    JJ.
    Opinion by Meredith, J.
    Filed: December 17, 2014
    Baltimore County, appellant, mounts a variety of challenges to an arbitration award
    regarding retirement benefits that was issued in 2008, affirmed in 2010 by the Circuit Court
    for Baltimore County, and ultimately affirmed again in 2012 by the Court of Appeals in FOP
    Lodge No. 4 v. Baltimore Co., 
    429 Md. 533
     (2012), reconsideration denied, 
    429 Md. 533
    (2013). Although the County contends that it is not appealing the arbitration award itself,
    but rather its enforceability, that contention is undermined by the arguments the County
    makes. In the rulings which led to the present consolidated appeals, the Circuit Court for
    Baltimore County held that, in accordance with the law of the case doctrine, the County was
    required to comply with the previously confirmed arbitration award. Under protest, the
    County did pay the amount due as a result of the arbitration award, but continues to challenge
    the enforceability of the award.
    QUESTIONS PRESENTED
    The County presented nine questions for our review, the majority of which had
    already been raised in proceedings prior to the previous appeal. The primary focus of the
    current appeal is:
    Did the trial court correctly apply the law of the case doctrine? 1
    1
    The following are the County’s questions presented:
    1.       Whether the arbitration award was unenforceable because there has
    never been an appropriation by the County Council to pay for the reset
    of the rates or for the ‘make whole’ relief granted in that award?
    2.       Whether the arbitration award was unenforceable because the County
    Council never enacted a budget containing funds for a reset or for make
    whole relief; instead it enacted FY 2008-2015 budgets which contained
    For the reasons that follow, we affirm the judgments of the Circuit Court for
    Baltimore County.
    the reduced subsidies negotiated by the Health Care Review
    Committee, and the Circuit Court was bound to respect those
    enactments as the only contract between FOP and the County?
    3.     Whether public policy, as clearly expressed in the Baltimore County
    Charter, the Baltimore County Code, and controlling Maryland case
    law, provides an exception to the enforcement of the arbitration award
    in this case?
    4.     Whether the Show Cause Order threatening incarceration was an
    unconstitutional exercise of judicial power calculated to coerce an
    appropriation or illegal payments in violation of the separation of
    powers doctrine?
    5.     Whether the arbitration award is unenforceable because the original
    grievance was not timely filed and the issue of the effect of that lack of
    timeliness on the arbitration award has never been resolved?
    6.     Whether the arbitration award is unenforceable as FOP’s grievance was
    invalid on its face, because under the MOU ‘retirees’ are not
    ‘employees’ entitled to bring any kind of grievance?
    7.     Whether the Circuit Court’s award of injunctive relief and damages to
    FOP was clearly erroneous, because FOP did not sustain any harm or
    damages as a result of the reduced subsidy rates?
    8.     Whether the Circuit Court’s refusal to allow the County’s witnesses to
    give any substantive testimony was clearly erroneous?
    9.     Whether FOP was entitled to prejudgment interest?
    As will be explained in this opinion, five of these questions (1, 2, 3, 5, and 6) have already
    been decided against the County in earlier decisions. We answer questions 7 and 8 in the
    negative, and we answer question 9 in the affirmative. Because question 4 is now moot, we
    decline to rule on the question.

    FACTS AND PROCEDURAL HISTORY
    This case has its roots in a grievance filed in 2007, although the backdrop to that
    grievance extends back to 1991. Appellee, FOP Lodge No. 4 (“appellee” or “FOP”), is the
    exclusive bargaining agent for the Baltimore County Police Department. Periodically, the
    FOP and the County negotiate a Memorandum of Understanding (“MOU”) setting forth each
    party’s rights and obligations. In 1991, owing to what the County has characterized as a bad
    economic climate, the County offered its eligible employees a retirement incentive program;
    among the County employees to whom it applied were FOP members. The retirement
    incentive program provided that eligible officers who retired on or before January 31, 1992,
    were guaranteed a 90/10 health-insurance subsidy split; that is, it was guaranteed to those
    retirees that the County would pay 90% of their health-insurance premium, and the retiree
    would pay 10%.
    The County notified those employees who did not take advantage of that incentive
    program that the health insurance split would be as follows: “An individual who retires on
    or after February 1, 1992, with 30 or more years of creditable service will receive the same
    subsidy as an active employee and that subsidy may go up or down as a result of labor
    negotiations[.]” But, as part of the negotiations for the 1996 MOU, which took effect on July
    1, 1995, the FOP and the County agreed that an 85/15 split would apply retroactively to those
    officers who retired between February 1, 1992, and July 1, 1995; they were, at that time,
    “locked in.” The specific language that “locked in” this split stated: “The health insurance
    3
    subsidy in place at the time of retirement shall remain in effect until the retiree becomes
    eligible for Medicare.” It was the FOP’s position that the practical effect of this provision
    was to guarantee an 85/15 subsidy split to those retirees.
    This arrangement was repeated in subsequent MOUs without dispute until the “2008
    MOU” that would become effective July 1, 2007, and run through June 30, 2008. During
    negotiations about that MOU, the County, citing runaway health-care costs, informed the
    FOP that it intended eventually to move to an 80/20 split, with a one-percent decrease in the
    County’s contribution to take effect each year in five successive years. The County proposed
    to change the benefit to an 84/16 split in 2008, followed by an 83/17 split in 2009, and so on.
    The FOP voted against this change, but it was nevertheless accepted by the Health Care
    Review Committee, the official bargaining agent as to healthcare issues for several unions
    for County employees, including the FOP. The County applied the less favorable split to all
    retirees, including those who had retired when there were MOUs in effect which included
    language the FOP considered a lock in of benefits.
    Pursuant to the procedures outlined in the relevant MOU, FOP filed a grievance
    against the County, alleging that the proposed downward adjustment of the health-care
    subsidy violated Section 7.3(a) and (c) of the 2007 MOU.2 The grievance was denied by the
    2
    Section 7.3 of the July 1, 2006-June 30, 2007 MOU (“2007 MOU”) provided, in
    relevant part:
    “Section 7.3(a)-Health Care Coverage
    Medical Plans. The County shall provide employees and retirees not eligible
    for Medicare with a Triple Option Medical Plan. Effective September 1, 2003,
    4
    Baltimore County will convert prior HCP and POS plans into the said Triple
    Option plan. The plan design shall be as follows. . . [chart omitted].
    The Triple Option Plan shall be available as an option to all active employees,
    all retirees not eligible for Medicare, and their eligible dependents.
    The County shall provide at least two (2) Health Maintenance Organization
    Plans (HMOs). These plans will also be available as an option to all active
    employees, all retirees not eligible for Medicare, and their eligible dependents.
    Subsidy. The County shall contribute 85% of the premium cost for the Triple
    Option Plan. Active Employees will pay 15% of the premium cost. Retirees
    not eligible for Medicare will receive a subsidy based on the amount of
    creditable service and consistent with County policy in force at the time of
    retirement.
    ***
    Section 7.3(c)-Retiree Health Insurance
    The County shall provide the same health insurance benefit plans offered to
    active employees for retirees not eligible for Medicare who attain sufficient
    creditable service for a full retirement within their bargaining unit, or retirees
    who qualify for disability retirement. The County will contribute toward the
    premiums for available benefit plans consistent with County policy in force at
    the time of retirement. The health insurance subsidy in place at the time of
    retirement shall remain in effect until the retiree becomes eligible for
    Medicare. Upon reaching eligibility for Medicare, County retirees are
    required to enroll in both part A and part B of Medicare in order to enroll in
    the County’s Medicare Supplemental Plan. The County subsidy for the
    Medicare Supplemental Plan is 75% of the plan premium.
    County retirees who would otherwise reach Medicare eligibility age, but who
    do not qualify on their own or through a spouse for Medicare coverage, will
    be allowed to remain in the County health plans offered to non-Medicare
    retirees. Upon reaching Medicare eligibility age, the County subsidy will be
    75% of the premium cost for the medical plan. Continuation of managed
    dental and vision coverage after reaching Medicare eligibility age is available
    only under the terms and conditions of Federal COBRA laws.”
    5
    Labor Commissioner on November 6, 2007; the Labor Commissioner concluded that,
    because FOP was complaining about a violation of Section 7.3 of the 2007 MOU, and that
    MOU expired on June 30, 2007, those sections were “no longer controlling,” and the County
    could not have violated them.
    FOP then demanded arbitration pursuant to the dispute-resolution provision of the
    MOU. On May 9, 2008, Arbitrator Richard Bloch, Esquire, conducted a hearing. One of the
    arguments made by the County was that the grievance had not been timely filed because it
    was not filed within ten workdays after the 2007 MOU’s expiration on July 1, 2007. Rather,
    the grievance was filed on September 14, 2007, which was within ten workdays of
    September 1, 2007, the date on which the County’s new 84/16 split began to be reflected in
    the retirees’ health-insurance premiums. The main argument made by the County, however,
    was that there was nothing left to either grieve or arbitrate relating to the now-expired 2007
    MOU. In his decision, Arbitrator Bloch rejected both of these contentions. Because the
    arbitrator’s findings have been affirmed in subsequent proceedings, and, we will hold, remain
    binding, we will quote from them extensively:
    During 1995 negotiations for a new collective bargaining agreement,
    the Union successfully negotiated a health insurance provision that locked in
    the subsidy in effect at the time of retirement until the retiree reached age 65.
    Moreover, the parties agreed to apply that benefit retroactively to officers who
    retired between February 1, 1992 and July 1, 1995, the effective date of the
    new Memorandum of Agreement (hereinafter “MOU”). Section 7.13 of the
    MOU stated, in relevant part:
    (Emphasis added.)
    6
    Section 7.13: Retiree Health Insurance-The County shall provide
    the same health insurance benefits (programs and contributions)
    for retirees under the age of sixty-five (65) as it does for active
    employees, at the time the employees retires (sic). The health
    insurance subsidy at the time of retirement will remain in effect
    until the retiree or the retiree’s surviving beneficiary reaches age
    sixty-five (65).
    Effective July 1, 1995, retirees who retired on or after
    February 1, 1992 shall receive the County contribution for
    health insurance as set forth above.[FN 3 OMITTED]
    As structured, this language had a two-fold impact. The first paragraph
    provided the “lock” for the subsidy in effect at the time of an officer’s
    retirement. The second paragraph ensured that officers who retired between
    February 1, 1992 and July 1, 1995 would receive the same guarantee with
    respect to the rate existing at their times of retirement. The language remained
    in subsequent MOUs until 2003-2004. [FN 4 OMITTED] The sole change at
    that time, however, related to removal of the sentence providing that
    “Effective July 1, 1995, retirees who retired on or after February 1, 1992 shall
    receive the County contribution for health insurance as set forth above.” (The
    parties did not then see that as a substantive change and do not claim here that
    it has any impact on the current dispute.) The critical lock-in language —
    “The health insurance subsidy in place at the time of retirement shall remain
    in effect until the retiree becomes eligible for Medicare” remained unchanged
    in the MOUs effective in 2004-2005, 200[ ]5-2006 and 2006-2007. [FN 5:
    “During those periods of time, the contribution split remained at 85/15.”]
    The dispute in this case centers on changes applicable to the July 1,
    2007 - June 30, 2008 MOU. In negotiations preceding the agreement, the
    County proposed the following language:
    E.     Retiree Health Insurance. The County shall provide the
    same health insurance benefit plans offered to active
    employees for retirees not eligible for Medicare who
    attain sufficient creditable service for a retirement within
    their bargaining unit, or retirees who qualify for
    disability retirement. The County will contribute toward
    the premium for available benefit plans in accordance
    with the Administrative Officer’s Policy, on Insurance
    7
    Benefits for Baltimore County retirees. Employees who
    retire from county service shall have the subsidy
    provided for in Exhibit (I). [FN 6 OMITTED]
    For all negotiations after 1995, the FOP, and other County unions, as
    well as a non-Union employee group, were represented (for health care issues)
    by a group known as the Health[care] Review Committee (“HRC”). [FN 7
    OMITTED] That Committee initially objected to the County’s proposed
    revised language, specifically the removal of the “lock-in” terms. [FN 8
    OMITTED] Nevertheless, the HRC agreed to the modified health insurance
    package. Ultimately, the final proposal from the County on retiree health
    insurance read as follows:
    E. Retire[e] Health Insurance
    “The County shall provide the same health insurance benefit
    plans offered to active employees for retirees not eligible for
    Medicare who attain sufficient creditable service for a
    retirement within their bargaining unit, or retirees who qualify
    for disability retirement: Individuals who retired prior to July 1,
    2007 who are Medicare eligible the County Subsidy for the
    Medicare Supplemental Plan is 75% of the plan premium. The
    County will contribute toward the premium for available benefit
    plans in accordance with the County Policy, on Insurance
    Benefits for Baltimore County retirees. Employees who retiree
    (sic) from county service shall have the subsidy provided for in
    Exhibit I.”
    Pursuant to the existing process, each union brought the health
    insurance package to its membership for separate votes. The FOP
    membership, for its part, rejected the health insurance package. On September
    7, 2007, the County moved to increase the retiree health insurance premium
    split. [FN 9 OMITTED]
    The FOP claims, in this arbitration, that the rejected portion of the
    health benefits package is not effective, as a result of its not having been
    ratified. Moreover, it contends the promises made during prior MOUs to
    retirees were in the nature of vested benefits and not only were not removed
    by the 2007 negotiations, but could not have been removed. Members covered
    by that language, it says, must continue to have health benefit subsidies remain
    at the level in effect at their retirement until they reach 65.
    8
    Issue
    Do officers who retired on or after February 1, 1992 and before
    July 1, 2007 have a vested right to retain the health insurance premium
    split applicable to active officers as of the time of their retirement? [FN 10
    OMITTED]
    FOP Position
    The FOP claims the promises made beginning in 1995 continue to be
    fully binding on the County. The right to lock in benefit splits at the levels in
    effect upon retirement is vested, says the FOP, and cannot be changed with
    respect to those employees. It requests the County be directed to: (1)
    rescind the modification to the premium split for such retirees, (2) reset
    the contribution split to the 85/15 level and (3) direct that the County shall
    not implement other scheduled changes to the premium split. It also
    requests that the County be ordered to make retirees whole for the
    increased premium amounts improperly charged to them since September
    1, 2007.
    County Position
    The County claims the grievance is not arbitrable. The grievance itself
    was filed September 14, 2007, based on language in the FY 2007 MOU. But,
    says the County, the previous MOU expired June 30, 2007. Any rights
    existing thereunder were thereby extinguished. Moreover, says the County, the
    MOU makes the grievance procedure applicable to “all employees.” The
    MOU defines an “employee” as “all sworn personnel up to and including the
    rank of lieutenant of the police department.” Since retirees are not
    “employees”, the FOP has no contractual right to grieve on their behalf. It
    requests that the grievance be denied.
    Analysis
    For the reasons that follow, the finding is this grievance has merit.
    Central to the County’s rebuttal to the grievance, and its claim that the
    grievance is not arbitrable, is its contention that the 2007 MOU, on which the
    FOP’s grievance is premised, has expired. In the absence of any statutory
    foundation for healthcare benefits [FN 11 OMITTED] since the grievance was
    filed some three months after expiration of the 2007 agreement, says the
    9
    County, the benefit expired and, with it, the arbitrator’s authority to enforce the
    labor agreement.
    The end of a labor contract, however, does not always signal the death
    of negotiated rights thereunder, including the right to have a dispute over that
    matter resolved through arbitration. That principle was decided by the United
    States Supreme Court in Nolde Brothers, Inc. v. AFL-CIO [(
    430 U.S. 243
    (1977) (FN 12 OMITTED)]. . . .
    . . . [T]he Supreme Court held the grievance in that case did, in fact, survive
    the contract termination. . . . Concluding, finally, that national labor policy has
    established a strong presumption in favor of arbitrability [FN 16 OMITTED]
    the Court affirmed the arbitrability of the matter.
    In Litton v. National Labor Relations Board, et al. [Litton Financial
    Printing Division, a Division of Litton Business Systems, Inc., Petitioner v.
    National Labor Relations Board, et al., 
    501 U.S. 190
     (1991)][FN 17
    OMITTED], the Supreme Court took the opportunity to expand on the Nolde
    principles. It reiterated that the obligation to arbitrate disputes over post-
    expiration contract terms is by no means unlimited. An expired collective
    bargaining agreement, noted the Court, is no longer a legally enforceable
    document. [FN 18 OMITTED] But the Court highlighted an exception,
    significant here, in cases involving “obligations already fixed under the
    contract but as yet unsatisfied.” [(
    501 U.S. 190
     at 197) (FN 19 OMITTED)]
    The Nolde Brothers presumption is limited to disputes arising
    under the contract. A postexpiration grievance can be said to
    arise under the contract only where it involves facts and
    occurrences that arose before expiration, where an action taken
    after expiration infringes a right that accrued or vested under the
    agreement, or where, under normal principles of contract
    interpretation, the disputed contractual right survives expiration
    of the remainder of the agreement.
    [(
    501 U.S. 190
     at 205-06.)]
    ***
    In this case, the ultimate question is whether the retiree rights at issue
    may be considered vested and thus capable of continuing enforcement. There
    10
    is, in this case, a companion issue, however, that raises the question of whether
    the retiree rights were terminated through bargaining by the FOP’s designated
    bargaining agent, the Health[care] Review Committee. This opinion turns now
    to both those issues.
    As noted earlier, the HRC, while initially protesting the removal of the
    “lock-in” language, ultimately agreed to management’s proposed change. But
    this, one concludes, did not result in the FOP’s forfeiting the rights at issue.
    [FN 21 OMITTED] According to the record, the FOP rejected the health
    insurance package proposed by the County. [FN 22 OMITTED] The County
    directs the arbitrator’s attention to the decision of Arbitrator M. David
    Vaughan, who concluded, in January of 2008, that the County did not engage
    in an unfair labor practice by refusing to negotiate further with the FOP after
    it rejected the County’s proposed language changes. Vaughan concluded,
    among other things, that the Health[care] Review Committee was the
    authorized representative of the Unions, including the FOP, and that there was
    no provision, contractually or statutorily, for a dissenting unit to demand
    additional negotiations. This, however, does not set to rest the status of the
    retiree language. Arbitrator Vaughan held, in his decision, that the rejected
    proposal would not be made part of the FOP MOU:
    There is no “next step” in bargaining health care issues
    following rejection. The rejected proposal is not incorporated
    into the MOU, but through the County’s budget process, it can
    be funded and implemented as a Management initiative, outside
    of collective bargaining.
    [FN 23 OMITTED]
    The arbitrator’s conclusion that the FOP MOU would not contain the revised
    language is consistent with the language in each Union MOU, including the
    FOP’s, in which “tentative agreements are subject to ratification by the
    membership of each employee organization.” [FN 24 OMITTED]
    Significantly, the jurisdiction of the unfair labor practice arbitrator was
    confined solely to the question of whether the FOP could demand additional
    bargaining with the County over the issue. Mr. Vaughan was clear, in his
    decision, that the contract question here at issue was not before him:
    There is apparently a contractual grievance, not before me, in
    the instant ULP claim, with regard to existing retirees and the
    County contribution for health Insurance. [FN 25 OMITTED]
    11
    The remaining question — whether retirees had a vested right to the
    benefit here sought is answered directly by the unequivocal language of
    the MOUs: The statement that “the health Insurance subsidy in place at
    the time of retirement shall remain in effect until the retiree becomes
    eligible for Medicare” is subject to no interpretation other than that here
    proposed by the FOP. When the parties bargained this language, they made
    a binding promise to retirees that the subsidy would remain at whatever
    level existed at their retirement. That is a vested right, and it was not, and
    could not be, changed by the negotiations discussed in this Opinion. For
    these reasons, the finding is that the grievance is timely and that it should be,
    and is, granted.
    AWARD
    The grievance is granted. Officers who retired on or after February
    1, 1992 and before July 1, 2007 have a vested right to retain the health
    insurance split applicable to them as active officers at the time of their
    retirement. The County is directed to rescind its modification, to reset the
    contribution split applicable to these officers to 85/15, to continue that
    split so long as, by the terms of the language, these officers remain eligible
    and to make whole affected retirees for increased premium amounts
    improperly charged to them since September 1, 2007.
    (Emphasis added.)
    As noted, the Arbitrator’s decision that the grievance was timely and that it should be
    granted — and the accompanying “award” — was entered on July 15, 2008.
    On August 14, 2008, the County filed a complaint in the Circuit Court for Baltimore
    County, seeking to vacate the arbitration award. In its complaint, the County made the
    following contentions:
    •            “the Arbitrator exceeded his power, in that he did not have jurisdiction
    over the Grievance, which was filed on September 14, 2007 after the
    expiration of the Memorandum of Understanding (MOU) between the
    Baltimore County Administration and the Fraternal Order of Police,
    12
    Lodge No. 4 which was in effect from July 1, 2006 through June 30,
    2007”;
    •           “the Arbitrator had no authority to provide the relief requested by the
    FOP [because] the Arbitrator’s Award rewrote the healthcare subsidy
    provisions of the FY 2008 MOU which had been negotiated by the
    Healthcare Review Committee, FOP Lodge 4's health insurance
    bargaining agent”;
    •           “[the] Grievance was moot, because the FY 2007 MOU had expired at
    the time the Grievance was filed on September 14, 2007”;
    •           “[b]ecause the FY 2007 MOU had expired on June 30, 2007, there was
    no agreement to arbitrate healthcare subsidy language contained in the
    expired FY 2007 MOU. Accordingly, there was no arbitration
    agreement as described in Section 3-206 of the Courts and Judicial
    Proceedings Article, the issue was not adversely determined in
    proceedings under Section 3-208 of the Courts and Judicial
    Proceedings Article, and Baltimore County raised its objection in the
    Arbitration Hearing and in its Post-Hearing Brief”;
    •           “[t]he Arbitrator’s Award usurps the power of the Baltimore
    County Executive and the Baltimore County Council to enact a
    budget which provides for health insurance and health insurance
    subsidies pursuant to the terms negotiated by the Healthcare
    Review Committee, FOP Lodge 4's bargaining agent”;
    •           “[there] is no vested future right to the specific benefits prescribed in
    the expired FY 2007 MOU, as established by long-standing practice
    and applicable law”; and
    •           “[t]he Arbitration Award is contrary to the very clear public
    policy, as stated in the Baltimore County Charter and Code, that
    the Baltimore County Council appropriates the funds needed to
    provide healthcare subsidies for retirees. The Arbitrator has no
    power or authority to order the Baltimore County Council to
    appropriate funds as stated in his Award.”
    (Emphasis added.)
    13
    The County further argued that “retirees” are not “employees,” and therefore FOP was
    not empowered to file a class grievance on behalf of retirees. The County asserted:
    Section 1.2 of the FY 2007 MOU states that “the term ‘employee’ shall mean
    all sworn personnel up to and including the rank of Lieutenant of the Police
    Department.” The award on its face relates to the rights of retirees. Since
    retirees by definition are not “employees” covered by the MOU, FOP did not
    have the contractual right to file a class grievance on behalf of retirees as set
    forth in Section 8.4 of the MOU, . . . .
    The County also contended that the “Award involves mistakes so gross as to constitute
    manifest injustice,” and that the award “contains mistakes of law and fact which are apparent
    on the face of the Award.” The County requested that the circuit court vacate the arbitration
    award and remand the matter back to the Arbitrator with instructions to deny the FOP’s
    grievance. On March 13, 2009, the County filed a Motion for Summary Judgment in which
    it presented arguments asserting the above points.
    On April 3, 2009, FOP filed an opposition to the County’s motion for summary
    judgment, along with FOP’s own cross-motion for summary judgment.
    On August 28, 2009, the Circuit Court for Baltimore County denied both the County’s
    motion for summary judgment and FOP’s cross-motion, and the motions judge explained that
    “[t]here are too many questions that need to be asked for summary judgment to be granted
    in this case.” Both parties filed motions for reconsideration, and by order of court filed
    October 21, 2009, the motions for reconsideration were denied.
    On May 24, 2010, motions for summary judgment were again heard by the Circuit
    Court for Baltimore County. On August 17, 2010, the court filed a memorandum opinion
    14
    and order denying the County’s motion for summary judgment and granting the motion for
    summary judgment filed by FOP. Because several of the issues addressed in the circuit
    court’s grant of summary judgment to FOP have been argued in this Court once again in the
    County’s present appeal, we will reproduce here portions of the circuit court’s August 17,
    2010, opinion and order in favor of FOP, which, as noted above, has been previously
    affirmed by the Court of Appeals.
    First, the circuit court found that the grievance was timely and the award was
    arbitrable. The circuit court stated: “Here, unlike the facts presented in [Barclay Townhouse
    Associates v. Stephen L. Messersmith, Inc., 
    67 Md. App. 493
     (1986), a case cited by the
    County in support of its argument that the determination of the existence of an agreement to
    arbitrate is made by the court rather than the arbitrator], there was a written agreement
    between the County and the FOP to arbitrate any grievance filed under the MOU. [FN 24
    OMITTED]” Accordingly, the court found the FOP’s claim properly subject to binding
    arbitration:
    Applying the principles established in Nolde and Litton, the Court finds
    that the grievance was arbitrable, despite the fact that the MOU had expired
    prior to its filing. The FY 2007 MOU clearly stated: “The health insurance
    subsidy in place at the time of retirement shall remain in effect until the retiree
    becomes eligible for Medicare.” [FN 41 OMITTED] The clear, unambiguous
    language of the agreement creates a promise to retirees that the subsidy in
    place when they retire will remain the same until they become eligible for
    Medicare. As such, the retirees at issue have a vested right to the maintenance
    of that subsidy until they become Medicare eligible. As the Court noted
    above, each MOU since FY 1996 has contained similar language.
    Additionally, the FY 1996 agreement retroactively included those officers that
    had retired between 1992 and 1995. Consequently, the officers that retired
    15
    while these agreements were in place obtained the vested right. Therefore, the
    FOP’s grievance, alleging that the County’s action of increasing the subsidy
    splits after the agreement had terminated infringed on the vested right to
    maintain the prior split, arose under the contract as defined by Litton. As a
    result, Arbitrator Bloch had proper jurisdiction to arbitrate the grievance.
    (Emphasis in circuit court’s opinion.)
    As noted, the circuit court specifically addressed, and rejected, the County’s assertion
    that the grievance was not timely filed:
    The County contends that Arbitrator Bloch should have dismissed the
    grievance for being untimely. The FOP’s grievance was related to the FY 2007
    MOU, which expired on June 30, 2007. Section 8.2 of the MOU required a
    grievance to be filed “within ten (10) workdays of the event giving rise to the
    grievance, or within ten (10) workdays following the time when the employee
    should have reasonably gained knowledge of its occurrence.” [FN 42
    OMITTED] Here, the County contends that the event giving rise to the
    grievance occurred on March 12, 2007 when the FOP rejected the terms
    negotiated by the HCRC for the FY 2008 MOU. The County further argues
    that because the FOP was claiming a vested right in the FY 2007 MOU, the
    grievance had to arise, at the latest, on the date the MOU expired — June 30,
    2007. The FOP didn’t file its grievance until September 14, 2007, which was
    more than ten workdays after the MOU had expired. As a result, argues the
    County, Arbitrator Bloch should have dismissed the grievance as untimely.
    The Court disagrees.
    The question of whether a grievance is timely filed is for the arbitrator.
    [FN 43 OMITTED] The Court finds no error with Arbitrator Bloch’s award
    in relation to the timeliness of the grievance. Even though the FY 2007 MOU
    expired on June 30, 2007, the actual infringement of the vested right contained
    within the agreement, and [which] was the subject of the grievance, did not
    occur until the County implemented changes to the health insurance subsidy
    splits on September 1, 2007. It was at that point the effected [sic] retirees
    became subject to increased subsidy splits, which gave rise to the grievance.
    The FOP filed its grievance on September 14th, which was within ten
    workdays of the event giving rise to the grievance, as required under the MOU.
    Therefore, Arbitrator Bloch did not err by not dismissing the grievance as
    untimely.
    16
    The court also rejected the County’s argument that retirees are not “employees”
    entitled to bring a grievance — an argument that the County has renewed in this appeal:
    The County contends that the FOP’s filing does not constitute a
    grievance because, under the terms of the MOU, the FOP may only file a
    grievance on behalf of employees. [FN 44 OMITTED] Section 1.2 of the
    MOU defines employees to “mean all sworn personnel up to an[d] including
    the rank of Lieutenant of the Police Department.” The County argues that
    since the FOP’s grievance was filed on behalf of retirees who, by the terms of
    the MOU, are not employees, the FOP did not have a contractual right to file
    a class grievance on their behalf.
    The County cites to Allied Chemical and Alkali Workers v. Pittsburgh
    Plate Glass Co. [(
    404 U.S. 157
     (1971)] to support its contention. [FN 45
    OMITTED] In Allied, the Supreme Court held that retirees are not employees
    within the meaning of § 8(a)(5) of [the] National Labor Relations Act and
    could not be included in the collective bargaining unit. [FN 46 OMITTED]
    At issue in the case was whether the employer had committed an unfair labor
    practice by making unilateral changes to retiree benefits instead of bargaining
    for those changes with the union. This is very different from the issue
    presented by the County in this present case.
    In United Steelworkers of America v. Canron, Inc. [(
    580 F.2d 77
     (3rd
    Cir. 1978)], the Court of Appeals for the Third Circuit was presented with a
    situation similar to this Court. In Canron, the union argued that the collective
    bargaining agreement obligated the employer to arbitrate a dispute over retiree
    benefits. [FNs 47 & 48 OMITTED] The employer countered that under Allied,
    the union lacked standing to sue on behalf of retirees. [FN 49 OMITTED] The
    Third Circuit rejected the employer’s contentions, reasoning that if the
    employer had contractually agreed to continue making premium payments for
    retirees, “then under accepted contract principles the union has a legitimate
    interest in protecting the rights of the retirees and is entitled to seek
    enforcement of the applicable contract provisions.” [FN 50 OMITTED]
    Specifically addressing the holding in Allied, the Third Circuit stated:
    Even though retirement benefits of former employees already
    retired are not a mandatory subject of collective bargaining, “it
    does not naturally follow, as the company implies, that a union
    loses all interest in the fate of its members once they retire.” We
    17
    therefore hold that the plaintiff union has standing to represent
    the retirees in seeking arbitration under its labor contract with
    Canron. [FN 51 OMITTED]
    The Third Circuit’s reasoning with regard to Allied is reinforced by the
    Eighth Circuit’s decision in Anderson v. Alpha Portland Industries, Inc. [(
    752 F.2d 1293
     (8th Cir. 1985)] [FN 52 OMITTED] In Anderson, retired employees
    sued their former employer in federal district court after the employer
    announced it was terminating insurance benefits for retirees. [FN 53
    OMITTED] The District Court entered summary judgment in favor of the
    employer on the basis that the retirees had not exhausted the grievance
    procedures referenced in the insurance agreement and contained in the
    collective bargaining agreement. [FN 54 OMITTED] In reversing the District
    Court, the Eighth Circuit rejected the employer’s contentions that case law,
    including Canron, required retirees to proceed through the union in order to
    pursue their disputes. [FN 55 OMITTED] However, the Court noted, Canron
    does provide “that a union has standing to assert retirees’ rights under a
    collective bargaining agreement to which it is a party if it chooses and that an
    employer may not refuse to arbitrate its contractual obligations with the
    union.” [FN 56 OMITTED] [(Emphasis in original.)]
    Here, it is clear that the FOP is a party to the FY 2007 MOU and that
    it has chosen to assert the rights of its retired members. As a result, the County
    may not refuse to arbitrate with the FOP over its contractual obligations to
    retirees. Based on the foregoing law, this Court finds that Arbitrator Bloch did
    not err in arbitrating the grievance made on behalf of retirees.
    The County also maintained that the arbitrator’s finding that the retirees’ rights to the
    subsidy split in place at the time of their retirement was vested was manifest error requiring
    vacation of the arbitration award, but the circuit court rejected this argument and explained:
    The County stridently maintains that Arbitrator Bloch’s finding of a
    vested right to the health insurance subsidy in place at the time of an officer’s
    retirement was an error so gross as to work a manifest injustice. The County
    contends that the letter of [the] County Administrator [] regarding the
    Retirement Incentive Program in 1991 made clear the County’s intention that
    health care subsidies for retirees could go up or down depending on future
    labor negotiations. [FN 57 OMITTED] In light of this fact, the County argues,
    18
    retiree health insurance subsidies are not vested rights and the language in
    Section 7.3(c) of the 1997 MOU can in no way be interpreted as providing
    such.
    ***
    Here, Arbitrator Bloch concluded that the language contained in Section
    7.3(c) was unequivocal and subject to only one interpretation — that the
    County made a binding promise to retirees that the subsidy split in effect at the
    time of their retirement would remain unchanged. Arbitrator Bloch’s
    conclusion is awarded a great deal of deference by this Court. [FN 60
    OMITTED] . . . Based on the foregoing facts and applicable law, the Court
    finds that Arbitrator Bloch did not commit manifest error, as alleged by the
    County, in concluding that the MOU created a vested right.
    Finally, the County made arguments related to its contentions that the arbitration
    award disregarded the negotiations of the Healthcare Review Committee, and that the award
    otherwise contravenes County budget procedures. These arguments are renewed in the
    present appeal. We will quote here the circuit court’s ruling relative to these arguments:
    Lastly, the County contends that Arbitrator Bloch exceeded his
    authority by effectively rewriting the health care subsidy provisions negotiated
    by the HCRC on behalf of the FOP for the FY 2008 MOU and by ordering the
    County to maintain the 85/15 subsidy split for officers that retired after
    February 1, 1992 and before July 1, 2007.
    Specifically, the County argues that Arbitrator Bloch exceeded his
    authority as set forth [at] Section 8.3, Step 4 of the FY 2007 MOU. That
    section provides:
    The arbitrator shall have no authority to add to, detract from,
    alter, amend or modify any provision of this Memorandum of
    Understanding or any rules or regulations of any agency of the
    County, or establish or alter any wage rate or wage structure.
    [FN 62 OMITTED]
    19
    The County further asserts that the Award was contrary to the Budgetary
    and Fiscal Procedures set forth in the Baltimore County Charter and the
    Baltimore County Code, which state the County Executive and County
    Council are responsible for enacting a budget and appropriating funds
    needed to run the County, including health care subsidies. Arbitrator
    Bloch’s Award, the County argues, usurped these powers by ordering the
    County to maintain and fund the 85/15 subsidy split.
    The FOP counters that Arbitrator Bloch’s Award concerned only the
    interpretation and enforcement of compensation terms that were previously set,
    and as such, does not usurp either the legislative or executive power of the
    County. The FOP points to the distinction between grievance arbitration,
    which uses a neutral third party to resolve a dispute over the interpretation of
    an existing contract, and interest arbitration, which uses a neutral third party
    to set the terms of a new contract. Under the prevailing case law, argues the
    FOP, grievance arbitration does not involve the delegation of legislative
    authority because the arbitrator is acting in [a] judicial capacity rather than a
    legislative one. [FN 63 OMITTED] “The authority to interpret an existing
    contract, therefore, does not constitute legislative authority, and the
    nondelegation principle is not implicated in grievance arbitration.” [FN 64
    OMITTED]
    The Court agrees with the FOP’s position. The County and the FOP
    agreed to submit “any dispute concerning the application or interpretation of
    the terms of [the FY 2007] Memorandum of Understanding” to binding
    arbitration. [FN 65 OMITTED] The grievance submitted to Arbitrator Bloch
    concerned the interpretation of Section 7.3(c), a contract term that had already
    existed and had been bargained for by the parties. In resolving the grievance,
    Arbitrator Bloch did no more than what was required of him – to interpret the
    disputed contract language in accordance with the facts presented and
    applicable law. Therefore, the Court finds that Arbitrator Bloch did not exceed
    his authority i[n] reaching his Award.
    (Emphasis added.)
    On August 19, 2010, the County noted its appeal of the circuit court’s grant of
    summary judgment in favor of FOP and the denial of the County’s own motion for summary
    judgment. In an unreported opinion filed on December 8, 2011, this Court reversed the
    20
    circuit court. We held that FOP had not been entitled to summary judgment in its favor as
    a matter of law, and that the County had demonstrated its entitlement to summary judgment.
    Baltimore County, Maryland v. Baltimore County Fraternal Order of Police, Lodge No. 4
    (No. 1428, September Term, 2010). In our opinion, we noted that, in the County’s brief, it
    had presented us with nine questions (which are strikingly similar to five of the questions
    raised by the County in the present appeal):
    1.     Whether the arbitrator lacked jurisdiction to arbitrate the grievance and
    whether the grievance was arbitrable, because the FY 2007 MOU had
    expired?
    2.     Whether the grievance was moot due to the expiration of the FY 2007
    MOU?
    3.     Whether the grievance was timely filed?
    4.     Whether the FOP’s late filing constituted a valid grievance since by
    definition “retirees” are not “employees” entitled to bring a class
    grievance?
    5.     Whether the Arbitrator had the authority to rescind and rewrite the
    language negotiated by the Health Care Review Committee, FOP’s
    health care benefit bargaining agent?
    6.     Whether there was a “vested right” to future health insurance benefits
    and subsidies prescribed in the expired FY 2007 MOU, based on the
    evidence, long-standing practice and applicable law, and whether it was
    manifest error for the Arbitrator to conclude so by relying on cases that
    interpret the NLRA?
    7.     Whether the Arbitrator’s own comments demonstrated the manifestly
    unjust and grossly mistaken nature of his award?
    8.     Whether the County clearly intended that health care subsidies would
    be negotiated annually and could “go up and down”?
    21
    9.     Whether, contrary to law and public policy, the Arbitrator’s Award
    usurped the power of the Baltimore County Executive and the
    Baltimore County Council to enact a budget which provides for health
    insurance and health insurance subsidies pursuant to the terms
    negotiated by the HCRC, FOP Lodge’s bargaining agent?
    In the footnote in which this Court recited the County’s nine questions presented in
    that previous appeal, we said: “For the reasons stated in our opinion, we cannot provide a
    certain answer to the County’s first question. Instead, we hold that the circuit court erred
    when it upheld the arbitration award and we leave the remaining questions to be resolved in
    a future arbitration or civil proceeding, if this litigation continues.” The mandate of this
    Court was: “Judgments Reversed. Case remanded to the Circuit Court for Baltimore County
    with instructions to enter judgment in favor of [the County]. Costs to be paid by [FOP].”
    But FOP’s petition for writ of certiorari was granted by the Court of Appeals. It
    appears that no cross-petition or conditional cross-petition was filed by the County. On
    November 19, 2012, the Court of Appeals reversed this Court’s judgment in favor of the
    County, and reinstated the judgment of the circuit court. The Court of Appeals ruled:
    We agree with the Circuit Court’s decision to leave undisturbed the
    arbitrator’s findings in this case. The fact that the MOU has expired does
    not mean the County had no duty to arbitrate disputes arising out of that MOU.
    A dispute may be arbitrable after the expiration of the underlying agreement,
    if the agreement contained a broad arbitration clause and the rights that are the
    subject of the dispute accrued or vested during the life of the agreement.
    The MOU’s arbitration clause was broad. It did not exclude grievances
    arising after the expiration of the MOU but pertained to “[a]ny dispute
    concerning the application or interpretation” of the MOU. The arbitrator
    found that FOP’s grievance was arbitrable even after the MOU’s expiration
    because — based on the arbitrator’s reading of the MOU’s health-insurance
    22
    clause — retirees’ rights to an 85/15 health-insurance premium split had vested
    at the time of their retirement. The Circuit Court was legally correct in
    granting summary judgment in FOP’s favor after subjecting the arbitrator’s
    findings to a deferential standard of review. Thus, we reverse the judgment of
    the Court of Special Appeals.
    FOP Lodge No. 4, supra, 429 Md. at 564-65 (emphasis added). The mandate of the Court
    of Appeals was not to remand to this Court so that all nine questions presented by the County
    in its 2011 appeal to this Court could be answered; instead, the mandate ordered a remand
    to this Court “with directions to affirm the judgment of the Circuit Court for Baltimore
    County” (emphasis added), with costs in both this Court and the Court of Appeals to be paid
    by the County.
    The County filed a motion for reconsideration in the Court of Appeals on December
    7, 2012. In that motion, the County asserted: 1) the FOP was bound by the negotiations of
    the Healthcare Review Committee (HCRC), which agreed to the reduction in the subsidy
    split (a reduction to which FOP expressly did not agree); and 2) “[c]onsistent with many prior
    decisions of this Court, this case should be remanded to the Court of Special Appeals for
    consideration of all undecided appellate issues.” As to this last point, the County specifically
    asserted the following:
    Of great practical consequence to the County, there has been no
    review of the following issue which was raised by the County in its Brief
    in the CSA:
    Contrary to law and public policy, the arbitrator’s award usurps
    the power of the Baltimore County Executive and the Baltimore
    County Council to enact a budget which provides for health
    23
    insurance and health insurance subsidies pursuant to the terms
    negotiated by the HCRC, FOP Lodge 4's bargaining agent.
    (Baltimore County’s CSA Brief at 34).
    The Arbitrator in this case had no power or authority to order the
    County Executive and the County Council to fund a split different from
    the negotiated split enacted into law as part of the FY 2008, 2009, 2010,
    2011 and 2012 budgets, to order the County Executive and County
    Council to reset the split at 85/15 in any future budgets, or to “make
    whole” affected retirees for increased premium amounts not budgeted by
    the County Executive and County Council.
    If this Court’s decision is allowed to stand, and this matter is remanded
    to the CSA with directions to affirm the judgment of the Circuit Court for
    Baltimore County, the Arbitrator’s affirmed award will be unenforceable, since
    there have been no funds appropriated through the executive budget process
    to afford the relief capriciously dictated by the Arbitrator.
    (Emphasis added.)
    On January 18, 2013, the Court of Appeals denied the County’s motion for
    reconsideration. 
    429 Md. 533
    . The mandate of the Court of Appeals issued the same day,
    and, as noted above, it directed this Court to affirm the judgment of the Circuit Court for
    Baltimore County. It did not direct this Court to consider further any other “undecided
    appellate issues.”
    On March 5, 2013, FOP filed in the circuit court a petition for award of costs and
    disbursements, seeking $130,691.90 in costs and disbursements, including attorneys’ fees.
    The petition was supported by billing records and an affidavit of trial counsel.
    On April 5, 2013, FOP filed in the circuit court a “motion to enforce this court’s
    judgment and for an order to show cause.” The motion asserted that the County “refuses to
    24
    comply with this Court’s judgment by providing the required relief.” FOP further asserted
    that the County’s refusal was “without any justification and accomplishes nothing other than
    to further delay resolution of this matter and gratuitously increase the parties’ expenses by
    unnecessarily prolonging litigation.” In support of the requested relief, the motion stated:
    . . . Notwithstanding the issuance of the mandate by the Maryland Court of
    Appeals and the order by the Court of Special Appeals vacating its earlier
    decision, the County refuses to provide the required relief.
    First, the County has refused to rescind its reduction of the retiree health
    care subsidy in effect at the time of each officer’s retirement. Stated
    differently, the County continues to overcharge retirees for health insurance.
    Second, the County refuses to make those retirees whole for the
    amounts that the County improperly charged to them. In this regard, the
    County has previously provided the FOP with a chart showing the amounts by
    which the County had charged each retiree above the rates in effect at the time
    of retirement. That chart, which is attached as Exhibit 3, shows that for
    overcharges through May of 2011, the County owes the retirees collectively
    $572,887.10, plus appropriate interest. The County has also refused to provide
    the data to calculate the amounts by which the County has overcharged retirees
    from May 2011 through the present.
    . . . In an effort to bring this longstanding litigation to a close without further
    delay or expense to either party, since the issuance of the Court of Appeals
    decision in November of 2012, FOP’s counsel has made many attempts to
    discuss with the County the County’s provision of the required relief to the
    affected retirees. On each occasion, the attorney for the County has stated
    simply that the County is continuing to consider its options. At no point,
    however, has the County offered any explanation as to why it was not
    providing the relief required by this Court’s order and judgment, as affirmed
    by the Maryland Court of Appeals, or a timeline by which it would provide the
    required relief.
    Accordingly, in order to resolve this matter without further litigation,
    on March 20, 2013, the FOP sent the County Attorney correspondence
    requesting that the County promptly take the following steps:
    25
    1.    Effective April 1, 2013, the County must provide each
    affected retiree with the retiree health subsidy in place at
    the time of his or her retirement.
    2.    The County must issue payment to the affected retirees
    in the amounts identified in [Exhibit 3] by Friday, March
    29, 2013.
    3.    In order to determine the additional amount that the
    County owes the affected retirees, by March 26, 2013,
    the County must update the attached chart [Exhibit 3]
    through March 31, 2013 (or later if the County fails to
    change the retiree health subsidy provided to the affected
    officers by that date) and provide the FOP with a copy of
    the entire chart in Microsoft Excel format.
    4.    The County agrees that it is required to pay pre- and post-
    judgment interest at the legal rate.
    . . . The County simply ignored this correspondence and continues to refuse
    to provide any of the relief required by this Court’s judgment. [FN 1
    OMITTED] . . .
    On April 23, 2013, the County filed a response to FOP’s motion to enforce the
    judgment. In its response, the County failed to refute FOP’s contention that the County was
    refusing to comply with the court’s order which confirmed the arbitration award. Instead,
    the County continued to dispute the validity of the arbitration award, and asserted once again
    that it was “contrary to the very clear requirements as stated in the Budgetary and Fiscal
    Procedures set forth in Article VII of the Baltimore County Charter and in § 10-1-113 of the
    Baltimore County Code.” The County argued that — despite the circuit court’s previous
    ruling which was affirmed by the Court of Appeals — under the Baltimore County Code,
    Charter, and
    26
    controlling case law, the Arbitrator had no power or authority to order the
    County Executive and County Council to fund a split different from the
    negotiated split enacted into law as part of the FY 2008, 2009, 2010, 2011,
    2012, and 2013 budgets, to order the County Executive and County Council
    to reset the split at 85/15 in any future budgets, or to “make whole” affected
    retirees for increased premium amounts not budgeted by the County Executive
    and County Council.
    The County further argued that the circuit court lacked the “power or authority” to
    enforce the arbitration award. The County also asserted: that “any rescission and resetting
    of the health care subsidy split would violate the agreement FOP’s bargaining agent, the
    Health Care Review Committee, made with the County”; that the circuit court’s August 10,
    2010, order granting summary judgment in favor of FOP did not constitute “an enforceable
    judgment against the County for a sum certain”; that the arbitrator lacked the authority “to
    rescind and rewrite the language negotiated by the Health Care Review Committee, FOP’s
    bargaining agent”; that “FOP never proved and the Arbitrator never determined the amount
    which would ‘make whole affected retirees’ or any liquidated sum that could be reduced to
    a judgment against the County”; that the “separation of powers doctrine prohibits this Court
    from ordering the County Executive and the County Council to appropriate funds, long after
    the Budgets for FY 2008-2013 have been enacted”; and finally, that “[e]nforcement of the
    Award at this stage of the proceedings would violate the County’s statutory right to have the
    [nine] issues it raised in the Court of Special Appeals [in the 2011 appeal] adjudicated.”
    On May 17, 2013, the circuit court held a hearing on FOP’s motion to enforce. At the
    hearing, counsel for the County indicated that the County was still pressing the arguments
    27
    it had raised in the first appeal. The application of the law of the case doctrine to the
    County’s public-policy argument is supported by the following colloquy:
    [BY THE COUNTY]:            Thank you, Your Honor. Before I discuss the
    seven arguments I presented in our response to
    the Motion to Enforce, I would like to
    characterize those seven arguments as essentially
    one argument which I did not articulate in specific
    terms but it is the public policy exception to the
    enforcement of an arbitration award and, in effect,
    our arguments, our seven arguments are asking
    this Court to find that as a matter of public
    policy as expressed in the Batimore County
    Charter and the Baltimore County Code, this
    matter is not enforceable. Now, there’s two
    parts to this procedure. One is our Complaint to
    Vacate the Award. [FOP’s counsel] has
    conveniently ignored the fact that the Court of
    Special Appeals reversed this Court and said that
    your decision was wrong. Now, is it wrong for us
    to believe an arbitrator’s award is beyond his
    powers to then file a Complaint to vacate that
    award with this Court. This Court agreed with the
    arbitrator, then file an appeal to the Court of
    Special Appeals, which agreed with us. So there
    is at least some debate here about the issues, legal
    issues. So up to the point where the Court of
    Special Appeals affirmed us, the case would have
    been in our favor. Of course, then I had to go
    through the Court of Appeals and, unfortunately,
    the Court of Special Appeals did not address the
    nine legal issues we raised, which we’re entitled
    to have addressed under the Court[s] and Judicial
    Proceedings Article in a direct appeal to that
    Court and if the Court will recall ----
    [BY THE COURT]:             But you made, you made that argument to the
    high, to the highest Court of this, of this State.
    28
    [BY THE COUNTY]:   I did, I argue, I did make the argument, I said
    —
    [BY THE COURT]:    And they rejected it, right?
    [BY THE COUNTY]:   Well, they did but the legal issues have not been
    decided, Your Honor. Where does that leave us?
    [BY THE COURT]:    It leaves you with a Court of Appeals opinion.
    [BY THE COUNTY]:   And the Court of Appeals opinion, to be quite
    frank with you, was rendered to, to that Court, to
    uphold a princip[le] concerning vesting. That’s
    all they were interested in. That was their agenda.
    Why? I don’t know. They didn’t want to hear
    anything else. They didn’t want to hear the fact
    that the bargaining agent for FOP and all of the
    unions sat down, negotiated with the County and
    agreed to this reduction. Simple contract law.
    They’re your agent, you agreed to it, the principal
    is bound. So if there’s any bad faith in this case,
    it’s the bad faith of the FOP. To sit, to agree that
    the health care agent is bargaining for them, they
    reach an agreement with the County and then FOP
    wants to pull the rug out from under the whole
    thing.
    [BY THE COURT]:    Well, that’s why the whole thing was litigated.
    [BY THE COUNTY]:   That’s correct.
    [BY THE COURT]:    And you have a Court of Appeals opinion.
    [BY THE COUNTY]:   But my, my point of bringing it up is we sat
    across the table with them and bargained with the
    health care bargaining agent and reached an
    agreement which now they want, they have
    nullified.
    29
    [BY THE COURT]:    Well, I mean, you don’t suggest that this whole
    issue has to be re-litigated?
    [BY THE COUNTY]:   No, I’m saying at this point, well, as far as I’m
    concerned, the nine issues remain unaddressed.
    The Court of Special Appeals said that the
    arbitrator did not address the County’s argument
    that the arbitration clause itself had expired. The
    Court [of Special Appeals] determined that this
    omission was a palpable mistake and the award
    should have been vacated. According to the
    Court of Special Appeals reversed the judgments
    of the Circuit Court granting FOP’s Motion for
    Summary Judgment and denying the County’s
    Motion for Summary Judgment which should
    have been granted. And the Court [of Special
    Appeals], in its footnote, first footnote in the case,
    listed the nine issues.
    [BY THE COURT]:    All right.
    [BY THE COUNTY]:   And indicated that those are, would only be
    addressed necessarily in any future litigation.
    [BY THE COURT]:    Well, that’s the Court of Special Appeals.
    [BY THE COUNTY]:   That’s correct.
    [BY THE COURT]:    The Court of Appeals is saying something
    different.
    [BY THE COUNTY]:   Well, the Court of Appeals never ruled on this
    issue. All they did was —
    [BY THE COURT]:    And the Court of Appeals is saying the Court of
    Special Appeals doesn’t need to.
    [BY THE COUNTY]:   They reversed the Court of Special Appeals and
    remanded it directly back to this Court for entry of
    judgment.
    30
    [BY THE COURT]:             Well, no, they remanded it to the Court of Special
    Appeals.
    [BY THE COUNTY]:            To have it remanded back here.
    [BY THE COURT]:             Right.
    [BY THE COUNTY]:            For entry of judgment —
    [BY THE COURT]:             They didn’t tell the Court of Special Appeals to
    address those issues.
    [BY THE COUNTY]:            No, they did not.     That was what we were
    requesting —
    [BY THE COURT]:             So what right do I have, what power do I have to
    do that?
    [BY THE COUNTY]:            You do not have that power. I’m just bringing
    it up as a matter of fairness. We had been denied
    the opportunity in a direct appeal to have our
    issues decided. . . .
    (Emphasis added.)
    In a later colloquy, the County attempted to explain why its current arguments about
    the unenforceability of the award were not exhausted:
    [BY THE COURT]:             So if, if, I guess I’m confused because if the, if
    the issue is that because there’s no
    appropriation made, tough luck, I guess
    basically, why did the County ever file to
    vacate the arbitration award? Why did you
    just, why didn’t you just say it’s not
    appropriated, we don’t need to worry about it.
    [BY THE COUNTY]:            Because we felt that there were very sound
    legal arguments to be made as to why that
    31
    arbitration award was erroneous. And, again
    —
    [BY THE COURT]:    But if it’s not appropriated, why waste five years?
    Why not just say, it’s not appropriated, we don’t
    have to pay it?
    [BY THE COUNTY]:   Well, as the matter moved forward, because there
    was no appropriation, because the health care
    agent, the health care review committee, the
    bargaining agent, had reached an agreement and
    under the budgetary process, that was the number
    that then became part of the budget submission
    that was passed by the Council and that has
    occurred each successive year. Now, why was it
    done? Because we felt like the, why did we
    appeal, why did we seek to vacate? Because we,
    we —
    [BY THE COURT]:    Yeah, I mean, if it’s not appropriated.
    [BY THE COUNTY]:   — thought it was wrong. We thought it was
    wrong and, it was legally wrong and we felt
    like we would win on that basis.
    [BY THE COURT]:    So win or lose, this was another argument you
    were, the County had that it was going to pull
    out of its back pocket at some time?
    [BY THE COUNTY]:   No, this was not pulled out of the back pocket,
    Your Honor. It was, it was —
    [BY THE COURT]:    Well, you’re, you’re saying it wasn’t appropriated
    so we don’t have to pay it. Why not just say,
    okay, the award is the award and we just don’t
    have to pay it because it’s not appropriated?
    [BY THE COUNTY]:   That’s what we’re saying now.
    [BY THE COURT]:    I know you’re saying that now.
    32
    [BY THE COUNTY]:             Now that they’re trying to enforce it.
    [BY THE COURT]:              So why’d you wait five years?
    [BY THE COUNTY]:             Because it was not at the position where it would
    be enforced. Now, it’s trying to, that’s point.
    [BY THE COURT]:              Okay.
    [BY THE COUNTY]:             The public policy does not allow its enforcement.
    We were trying to attack the legal basis, that, we
    were trying to attack the award as legally
    unsound for the reasons which have never been
    decided by any Court. Now that it’s being
    enforced or attempted to be enforced, we’re
    saying public policy bars its enforcement.
    (Emphasis added.)
    The circuit court took the matter under advisement, and allowed the County to file a
    supplemental memorandum in support of its public policy argument. On August 14, 2013,
    the circuit court issued a memorandum opinion and order granting FOP’s motion to enforce.
    This order was docketed on August 28, 2013.
    The circuit court’s opinion took note of all the arguments presented by the County,
    and concluded that the law of the case doctrine barred any further consideration of the
    arguments about the enforceability of the award. The circuit court ordered the County to take
    the following actions within twenty days: 1) “provide each affected retiree with the retiree
    health subsidy in place at the time of his or her retirement”; 2) “issue payment in the amount
    of” $572,887.10, “plus appropriate interest, which is the amount referenced in the chart
    previously prepared by [the County] and provided to [FOP] in May of 2011, attached as
    33
    Exhibit 3 to [FOP’s] Motion to Enforce,” and “issue payments directly to each affected
    retiree in the proportions set forth in the chart prepared by [the County]”; and 3) update the
    previously-referenced damages chart with “information sufficient for [FOP] to calculate a
    sum certain judgment to which it is entitled, including any appropriate pre[-] and post[-
    ]judgment interest,” and provide FOP with a copy of the updated damages chart.
    On September 6, 2013, the County filed a motion to alter or amend the judgment
    pursuant to Maryland Rule 2-534. On October 9, 2013, FOP filed its response. On October
    15, 2013, the court conducted a hearing on the County’s motion. At the hearing, the County
    continued to raise issues regarding the timeliness of the initial grievance and whether or not
    retirees were entitled to pursue a grievance. The County again pointed to the nine issues it
    had previously raised in its first appeal to this Court, and the County also renewed its public
    policy arguments about the County’s failure to make an appropriation to pay the amounts
    ordered by the Arbitrator. At one point during the hearing, counsel for the County seemed
    to disavow the reliability of the damages chart which had been previously provided by the
    County:
    [BY THE COURT]:              Does the, does the County dispute the numbers on
    this chart?
    [BY THE COUNTY]:             To be honest with you, I don’t know what the
    numbers really mean and I haven’t sorted through
    them. I don’t know, at this point, who prepared
    them. I haven’t been able to track it down. So,
    no, I don’t agree with, and I think I need to, I,
    there has to be an opportunity for us —
    34
    [BY THE COURT]:    This is, this is the document, as I recall, that the
    County supplied to the FOP?
    [BY THE COUNTY]:   As part of a global settlement discussion of all
    cases.
    [BY THE COURT]:    I understand that, but is there any, is there any
    dispute as to anything on that chart?
    [BY THE COUNTY]:   I dispute it because I don’t know what it says and
    I don’t know how it was arrived at.
    [BY THE COURT]:    Have you, have you had a chance to review it?
    [BY THE COUNTY]:   I have reviewed it.
    [BY THE COURT]:    You have?
    [BY THE COUNTY]:   Yes.
    [BY THE COURT]:    So having reviewed it, is there anything that you
    dispute on it?
    [BY THE COUNTY]:   Excuse us, Your Honor. Basically, there, the
    numbers are unsubstantiated in any manner which
    would, could relate to evidence that a judgment
    could be based on, Your Honor.
    [BY THE COURT]:    I’m just asking if you dispute anything on it?
    [BY THE COUNTY]:   I dispute them, yes, I do.
    [BY THE COURT]:    You dispute, you don’t know how the County
    created it, prepared it and transferred it to the
    opposing party in good faith negotiations for a
    global settlement, you dispute what’s on there, is
    that what you’re telling this Court?
    [BY THE COUNTY]:   I personally don’t know what it says or who
    prepared it, therefore, I have to dispute it.
    35
    [BY THE COURT]:    Okay. All right.
    [BY THE COUNTY]:   And it’s not substantiated in terms of a piece of
    evidence that you put somebody on the stand and
    say, Mr. Jones —
    [BY THE COURT]:    I, I, I understand your evidentiary point. My
    question is, this document that the County
    prepared and presented to the FOP, does the
    County dispute what’s on the County’s
    document?
    [BY THE COUNTY]:   I can’t speak for the County because I can only
    speak for myself.
    [BY THE COURT]:    You’re, you’re representing the County.
    [BY THE COUNTY]:   My investigation of it revealed that I couldn’t
    identify who had prepared it. Without that,
    talking to that person, I have to dispute it.
    [BY THE COURT]:    Okay. But as of this point in time, which has
    been, I don’t know when you turned the document
    over, it’s been several years though, right? Two
    thousand eleven?
    [BY THE COUNTY]:   Yes, it’s been a while.
    [BY THE COURT]:    All right. So it’s been about two, over two years.
    Has anything come to your attention, to the
    County’s attention, to, to bring into dispute
    anything on that document?
    [BY THE COUNTY]:   No, because it never came up. The settlement
    negotiations ended and that was the end of that.
    There was not a settlement reached and, therefore,
    the document became irrelevant.
    [BY THE COURT]:    All right. Have you reviewed it since the Court’s
    Order back in, several months ago?
    36
    [BY THE COUNTY]:   Your Honor’s Order?
    [BY THE COURT]:    Um hm. Have you reviewed the document?
    [BY THE COUNTY]:   No, I haven’t really, I’ve looked at it but I
    haven’t reviewed it. I’m not —
    [BY THE COURT]:    Has anything, is there anything to dispute now
    about that document?
    [BY THE COUNTY]:   Yes, the whole thing.
    [BY THE COURT]:    Okay.
    [BY THE COUNTY]:   On both substantive, it’s unsubstantiated and on
    evidentiary grounds. I think Your Honor —
    [BY THE COURT]:    What substantively is incorrect on it?
    [BY THE COUNTY]:   It has, the document hasn’t been substantiated by
    the testimony of a witness who can say ----
    [BY THE COURT]:    What, what facts on the document are in dispute?
    [BY THE COUNTY]:   Well, I wouldn’t know that until I have a witness
    on the witness stand to know what’s in dispute
    and be able to either not prove it or prove it.
    [BY THE COURT]:    All right.
    [BY THE COUNTY]:   I’m not trying to play a game, Your Honor. I, I
    just, you know, this is a document that was
    prepared for settlement discussion. Now, it’s
    providing the basis for a, I guess, a half million or
    a million and a half dollar judgment.
    [BY THE COURT]:    Well, I guess I can understand if there’s a dispute
    as to the amount or the, or the facts on that
    document, there’s a bona fide dispute about that,
    then you need an evidentiary hearing.
    37
    [BY THE COUNTY]:             I can’t, I can’t, as I stand here say —
    [BY THE COURT]:              But if there’s no, if there’s no dispute, then
    there’s no need for a hearing.
    [BY THE COUNTY]:             There’s –
    [BY THE COURT]:              If you’re disputing —
    [BY THE COUNTY]:             Yes, I’m disputing —
    [BY THE COURT]:              If you, as the representative for the County, is
    disputing the document that the County prepared,
    I’d like to know what, what is it about that
    document that the County prepared that the
    County disputes.
    [BY THE COUNTY]:             I’m not sure if the numbers are accurate.
    [BY THE COURT]:              Okay.
    [BY THE COUNTY]:             But either way, I don’t think it’s a document that
    Your Honor can use because it’s part of a
    settlement discussion under the Rules of
    Evidence. In any event, and, and it shows that
    rather than using a document that was part of a
    settlement discussion, there needs to be a hearing
    where somebody proves something.
    [BY THE COURT]:              So, so you’re saying the County entered into a
    settlement discussion without vetting the
    document that’s being used as the basis for that
    negotiation?
    [BY THE COUNTY];             I have no idea. I wasn’t part of that.
    In response to the County’s refusal to admit the reliability of the document that it had
    previously prepared and provided to the FOP, the court permitted a brief period of discovery
    38
    for the purpose of ascertaining the damages amount, and the court scheduled a damages
    hearing for January 28, 2014. As part of its order of November 5, 2013, the court stayed
    paragraphs 3 and 4 of its order of August 28, 2013; in other words, it stayed the part of the
    order requiring the County to pay $572,887.10, “plus appropriate interest,” and to update the
    damages chart within 20 days.
    On November 8, 2013, the County noted an appeal to this Court of the November 5,
    2013, order. It also filed a motion for a stay pending appeal, which was denied by the circuit
    court in a memorandum opinion and order filed on December 15, 2013. The County then
    made application to this Court for a stay pending appeal, and that was denied on December
    26, 2013.
    A damages hearing was held on February 6, 2014. Admitted in evidence as FOP’s
    Exhibit 1 was an updated chart, provided by the County, showing that the updated damages
    amount through the end of January 2014 was $1,413,120.81. That balance was growing by
    approximately $28,000 per month for every month the County refused to comply with the
    court’s previous orders to reset the subsidies and “make whole” the retirees. FOP produced
    an expert economist who testified as to pre- and post-judgment interest, which, at the time
    of the damages hearing, was “a little over $219,000 in total” and growing by “approximately
    $7,000 to $8,000 of interest each month.” FOP also produced evidence showing that its total
    attorneys fees were up to $240,412.80.
    39
    At the damages hearing, the County again argued that FOP was entitled to no damages
    whatsoever. FOP called as its first witness Becky Ellis, a health-insurance administrator for
    the County and the individual who prepared the damages spreadsheet at issue that reflected
    that the County owed the affected retirees in excess of $1.4 million. The County objected
    to the admission of the document prepared by its employee at its direction on the basis that,
    “although it’s authentically what she prepared, what [it] is being presented for is not
    proper[.]” The objection was overruled.
    When it came time to cross-examine Ms. Ellis, the County asked its employee, “[d]oes
    the County owe the retirees [ ] damages?” The question drew an objection that was sustained.
    The County explained that the question “relates to our argument that these retirees are
    entitled to zero damages.” The County then proffered that Ms. Ellis’s “answer would be that
    there are no damages because the Health Care Review Committee agreed to the change in
    the subsidy rate.”
    FOP then called its expert economist, Dr. Amy McCarthy, to testify regarding her
    interest calculations, which showed that the amount of interest that accrued between
    September 1, 2007, and December 31, 2013, was $219,175.22.
    The County was then permitted to call a witness, Fred Homan, out of turn. Mr.
    Homan testified that he was the County administrative officer, “responsible for the day-to-
    day operation of the county.” Prior to holding his then-current position, Mr. Homan had been
    the Director of Budget and Finance for the County from November 1989 until July 2007.
    40
    The County’s repeated attempts to have Mr. Homan testify that it was his opinion that the
    retirees were not due any compensatory damages drew objections that were sustained, but
    the County was permitted to proffer what Mr. Homan’s testimony would be. Among the
    contentions appellant makes on this appeal is a claim that the court, in sustaining “virtually
    every objection by FOP to every substantive question posed to the County’s witnesses,”
    committed legal error in “refus[ing] to allow the County’s witnesses to give any substantive
    testimony” at the February 6, 2014 damages hearing. The following colloquy reflects the
    proffered testimony that was excluded.
    [BY THE COUNTY]:             Mr. Homan, in your capacity as the County’s
    administrative officer and being the director of
    Budget and Finance, you’re familiar with the
    County’s executive budget system —
    [BY FOP’S COUNSEL]:          Your Honor, I object to the relevance of what I
    am now imagining this entire line of questioning
    to be, to not be about ascertaining the amount of
    damages which is the sole purpose of this hearing,
    but instead to relitigate for countless time the
    merits of this litigation.
    [BY THE COURT]:              Mr. [County’s counsel]?
    [BY THE COUNTY]:             Your Honor, again, this goes back to our
    contention that with respect to this damages
    hearing there are no damages, and Mr. Homan
    will explain why.
    [BY THE COURT]:              Okay. I’ll sustain the objection.
    [BY THE COUNTY]:             Then I would like to make a proffer.
    ***
    41
    Mr. Homan will testify that under the County’s
    Executive Budget System as set forth in the
    Baltimore County Charter and Code, specifically
    Section 715 of the Charter and Section 10-1-113
    of the Baltimore County Code, which if he were
    allowed to testify I would offer as exhibits in
    support of his testimony. The Executive Budget
    System entered into and formed a part of the FY
    2007 MOU as if expressly referred to and
    incorporated into the MOU, and that’s under
    Maryland case law.
    Under that system any agreements [a]ffecting
    appropriations are fully subject to the County’s
    annual budget process. This principle embraces
    unlike those provisions which [a]ffect the validity,
    construction, discharge, and enforcement of a
    contract. Even if the retirees had a vested right to
    certain rates, that vested right was fully subject to
    the Executive Budget System and the agreement
    negotiated by the Health Care Review Committee.
    I’d then ask Mr. Homan the following question —
    well, I will ask him and if there’s an objection I’ll
    proffer the answer.
    [BY THE COURT]:       All right.
    [BY THE COUNTY]:      Do you agree or disagree with the following
    statement, Mr. Homan? If the final enacted
    ledger contains the agreed upon appropriations
    from which health care subsidies should have
    been paid, then is the County obligated to pay —
    [BY FOP’S COUNSEL]:   I’m gonna object on two —
    [BY THE COURT]:       All right. Sustained.
    [BY FOP’S COUNSEL]:   I don’t even believe a proffer is appropriate
    because you’re the judge and he’s asking now Mr.
    42
    Homan. That question is improper, period,
    because —
    [BY THE COURT]:       I sustained the objection, and you may proffer.
    [BY THE COUNTY]:      The answer — the proffer would be as follows: If
    the final enacted budget contains the agreed upon
    appropriations from which health care subsidies
    should have been paid, then the County is
    obligated to pay, but if the final enacted budget
    contains less appropriations than were previously
    agreed upon, then the budget controls and the
    County is only liable up to the amount actually
    appropriated.
    Next question, Mr. Homan, do you agree with the
    following statement? If the final enacted budgets
    for FY 2008 to 2014 contain the health care
    subsidy reductions agreed to by the Health Care
    Review Committee, then the County is under no
    obligation to pay any other subsidy —
    [BY FOP’S COUNSEL]:   Objection, Your Honor.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be that if the final enacted
    budgets —
    [BY THE COURT]:       This is a proffer.
    [BY THE COUNTY]:      This is a proffer, correct. If the final enacted
    budgets for FY 2008 to 2014 contain the health
    care subsidy reductions agreed to by the Health
    Care Review Committee, then the County is not
    under any obligation to pay any other subsidy.
    Next question, Mr. Homan, under the C[h]arter
    and the Code can the County comply with any
    order of the Court to “issue payment” of alleged
    43
    excess contributions to affect[ed] retirees “plus
    appropriate interest” ---
    [BY FOP’S COUNSEL]:   Objection, Your Honor.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      And the answer would be —
    [BY THE COURT]:       Proffer.
    [BY THE COUNTY]:      The proffer would be no. The next question
    would be why not, and the answer would be —
    [BY FOP’S COUNSEL]:   Your Honor, if you want me to object to —
    [BY THE COURT]:       I think you should object.
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The proffer would be because there has never
    been an appropriation ordinance by the county
    coun[ci]l for such payments.
    Next question, Mr. Homan, under the Charter and
    Code can the County comply with any order by
    this Court that the County “shall provide each
    effective [sic] retiree with [the] health care
    subsidy in place at the time of his or her
    retirement” ---
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be no. The next question to
    Mr. Homan, why not —
    44
    [BY FOP’S COUNSEL]:         Objection.
    [BY THE COURT]:             Sustained.
    [BY THE COUNTY]:            The answer would be —
    [BY THE COURT]:             It’s a proffer. They’re all proffers.
    [BY THE COUNTY]:            The proffer would be because there’s never been
    an appropriation ordinance by the county
    coun[ci]l for such reset or such repayments —
    such payments, pardon me. That would be Mr.
    Homan’s testimony.
    A similar pattern of proffers was used during the examination of the County’s two
    other witnesses at the damages hearing, Keith Dorsey and George Gay. Mr. Dorsey testified
    that, since July 2007, he has been the Director of Budget and Finance for Baltimore County.
    The following colloquy is pertinent:
    [BY THE COUNTY]:            Now, pursuant to the budget bearing physical [sic]
    proceedings of the County Charter and the County
    Code, was the County Council in its budgetary
    enactments for FY 2008 and 2014 appropriated
    the funds to pay for the health care subsidy split
    negotiated by the Health Care Review Committee
    in 2007?
    [BY MR. DORSEY]:            Yes, I did —
    [BY FOP’S COUNSEL]:         Objection, your Honor. This is outside the scope
    of today’s hearing.
    [BY THE COURT]:             All right. Sustained. Strike the question and the
    answer.
    [BY THE COUNTY]:            Well, observe the same —
    45
    [BY THE COURT]:       You can make a proffer.
    [BY THE COUNTY]:      — process. I will proffer that the answer will be
    the County has appropriated the funds to pay for
    the health care subsidy split negotiated by the
    Health Care Review Committee in 2007.
    Next question, Mr. Dorsey, has the County
    Council in its budgetary enactments fiscal year
    2008 to 2014 appropriated the funds to pay for
    health care subsidy split in effect prior to July 1,
    2007 —
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      I’ll proffer, your Honor. The answer would be
    no.
    Next question, Mr. Dorsey, has the County
    Council appropriated the funds for any alleged
    damages claimed in this case —
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The proffer would be that the County Coun[ci]l
    has not appropriated any funds to pay for any
    alleged damages claimed in this case.
    Mr. Dorsey, the next question is has the County
    Council appropriated the funds to pay for any
    retroactive reset of the retiree health care subsidy
    splits to their pre-July 1, 2007 level –
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    46
    [BY THE COUNTY]:           The proffer is that the County Council has not
    appropriated the funds for any retroactive reset of
    the health care retiree subsequent to their pre-July
    1, 2007 level.
    Mr. Dorsey, has the County Council appropriated
    the funds to pay for any award of interest,
    attorney fees or litigation expenses in connection
    with this case —
    [BY FOP’S COUNSEL]:        Objection.
    [BY THE COURT]:            Sustained.
    [BY THE COUNTY]:           The proffer would be the answer is no, the County
    Council has not appropriated the funds to pay for
    any award of interest, attorney fees or litigation
    expenses. That would be the testimony of — the
    proffered testimony of Mr. Dorsey.
    George Gay testified next on behalf of the County. At the time of the damages
    hearing, Mr. Gay was the County’s Director of Human Resources, but in his previous
    position as Labor Commissioner, he denied the FOP’s initial grievance in this matter
    following a hearing on November 6, 2007. Mr. Gay’s testimony, in part, was as follows:
    [BY THE COUNTY]:           Let me show you what has been marked as
    Plaintiff’s Exhibit 5. Do you recognize that?
    [BY MR. GAY]:              It appears to be the grievance filed by the FOP
    concerning the health care subsidy split.
    [BY THE COUNTY]:           Is this the grievance that resulted in a hearing that
    you conducted?
    47
    [BY MR. GAY]:              I didn’t.[3]
    [BY THE COUNTY]:           What was your finding in connection with that
    hearing —
    [BY FOP’S COUNSEL]:        Objection, your Honor. It’s outside the scope of
    today’s hearing.
    [BY THE COURT]:            Sustained.
    [BY THE COUNTY]:           I will proffer that the result was the grievance was
    denied.
    Mr. Gay, do you see where in the box where it
    says [“]employee’s name[”], the [“]Baltimore
    County FOP Lodge 4[”] appears?
    [BY MR. GAY]:              Yes.
    [BY THE COUNTY]:           Is FOP Lodge 4 an employee —
    [BY FOP’S COUNSEL]:        I object, your Honor. Same objection.
    [BY THE COURT]:            Sustained.
    [BY THE COUNTY]:           The answer would be as I proffer it, your Honor,
    no.
    Do you see down where it says “Box 2 What do
    you think should be done about it?” You see
    that?
    [BY MR. GAY]:              Yes, uh-huh.
    [BY THE COUNTY]:           You see anywhere in that box where the FOP
    requested, “Make whole relief” ---
    3
    We assume this is a transcription error; Mr. Gay did conduct a hearing on FOP’s
    grievance on November 6, 2007, and denied the grievance in an opinion he issued on
    November 19, 2007.
    48
    [BY FOP’S COUNSEL]:   Objection, your Honor. It’s outside the scope.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be no, that’s the proffer. If I
    could have Exhibit Number 2, please.
    I’m showing you what’s been previously marked
    and admitted into evidence as Exhibit Number 2,
    which is the complaint filed in this case.
    I want to direct your attention to Exhibit 2
    attached to that complaint, which is the FY 2000
    MOU between Baltimore County and FOP Lodge
    4. Do you recognize that?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      In looking at that can you explain what the health
    care subsidy split was as it existed as of the
    effective date and up to the time it became
    expired of that MOU?
    [BY MR. GAY]:         It varies based on the levels of coverage, because
    there’s an HCP, there’s also a triple option plan.
    [BY THE COUNTY]:      You said what is it, an HCP?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      What does that mean?
    [BY MR. GAY]:         Health care preferred, and a PLS plan into said
    triple option plan.
    [BY THE COUNTY]:      Okay. Is it accurate to say that the amount of the
    subsidy is various subsidies for the different
    health plans in this MOU are different from what
    was negotiated by the Health Care Review
    Committee in 2007 —
    49
    [BY FOP’S COUNSEL]:   Objection, your Honor.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer as proffered would be yes, these are
    different.
    Let me show you what has been marked as the
    next County Exhibit, which is Number 6. Do you
    recognize that document?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      What is it?
    [BY MR. GAY]:         It’s   p o rtio n s of th e m e m o ra n d u m o f
    understanding between the County and the
    American Federation of State, County and
    Municipal Employees.
    [BY THE COUNTY]:      What fiscal year is this MOU effective?
    [BY MR. GAY]:         July 1st of 2007 through June 30 of ‘08.
    [BY THE COUNTY]:      So, could we call that one the FY 2008 MOU with
    A[FS]CME?
    [BY MR. GAY]:         Correct.
    [BY THE COUNTY]:      Does that MOU incorporate the changes that were
    negotiated by the Health Care Review Committee
    during negotiations with that committee regarding
    the health care subsidies —
    [BY FOP’S COUNSEL]:   Your Honor, I object to the question and I also
    object to the admission of the document, both are
    outside the scope.
    [BY THE COURT]:       Care to be heard, Mr. [County’s counsel]?
    50
    [BY THE COUNTY]:      Just trying to establish that the A[FS]CME — this
    is an illustrative MOU. The Health Care Review
    Committee negotiated the changes on behalf of all
    the unions, and they voted in favor of the changes,
    and FOP was the only one who would not go
    along with the changes. That’s why they filed a
    grievance. All the other unions as illustrated by
    this MOU of A[FS]CME agreed to the changes
    and have abided by them ever since then. This
    MOU does contain the changes negotiated by the
    Health Care Review Committee.
    [BY THE COURT]:       All right. Sustained.
    [BY THE COUNTY]:      I think my explanation, I ask that be considered
    the proffer.
    [BY THE COURT]:       It is.
    [BY THE COUNTY]:      Just to be clear I offer it into evidence at this time,
    that is the MOU.
    [BY THE COURT]:       Any objection?
    [BY FOP’S COUNSEL]:   Yes, I object to the admission of the document.
    [BY THE COURT]:       Sustained. It will not be admitted.
    [BY THE COUNTY]:      Mr. Gay, going back to Exhibit 2 attached to the
    complaint you have in front of you, which is the
    FY FOP —
    [BY MR. GAY]:         FOP, yes. Exhibit 2, I have that.
    [BY THE COUNTY]:      Do you see under Section 1.2 which appears, the
    page designated E22, the definition of employee
    —
    [BY FOP’S COUNSEL]:   Objection, your Honor. It’s outside the scope.
    51
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be yes, he does see that. I
    would ask him then to read the definition, and it
    would be read as follows: “Employee defined.
    Whenever used in this memorandum of
    understanding, the term ‘Employee’ shall mean all
    sworn personnel up to and including the rank of
    lieutenant of the police department.”
    Mr. Gay, the meaning of employee there, does
    that include retirees —
    [BY FOP’S COUNSEL]:   Objection, your Honor.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The proffer would be that the term employee as
    defined herein does not include retirees.
    Does a person who is not an employee have the
    right to bring a grievance?
    [BY FOP’S COUNSEL]:   Objection, your Honor.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be no, they do not have a right
    to bring a grievance.
    Turning to page E35 of the document, Mr. Gay,
    do you see Section 8.4, Class Grievance?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      Could you read that, please —
    [BY FOP’S COUNSEL]:   Objection, your Honor.
    [BY THE COURT]:       Sustained.
    52
    [BY THE COUNTY]:      The reading would be if the grievance —
    [BY FOP’S COUNSEL]:   Your Honor, it’s already in the record. It doesn’t
    need to be read into the record.
    [BY THE COURT]:       Okay. It’s in the record.
    [BY THE COUNTY]:      Okay.
    Are retirees employees entitled to bring a chance
    [sic] grievance?
    [BY FOP’S COUNSEL]:   Objection.
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      The answer would be no.
    Take a look, if you would, at Section 7.2(d), page
    E29. Do you see that first sentence?
    [BY MR. GAY]:         Say that again, please.
    [BY THE COUNTY]:      Page E29, Section 7.2(d), Health Care Bargaining
    Agent. Do you see that?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      The first sentence?
    [BY MR. GAY]:         Yes.
    [BY THE COUNTY]:      What does that state?
    [BY FOP’S COUNSEL]:   Objection, your Honor. It’s already in the —
    [BY THE COURT]:       Sustained.
    [BY THE COUNTY]:      Mr. Gay, in your experience have you ever seen a
    claim for award of attorney’s fees in connection
    53
    with a grievance, an arbitration or a complaint to
    vacate an arbitration award?
    [BY MR. GAY]:                  No, I haven’t.
    [BY THE COUNTY]:               Is there any provision in the MOU to support such
    a claim with such an award —
    [BY FOP’S COUNSEL]:            Objection, your Honor.
    [BY THE COURT]:                Sustained.
    [BY THE COUNTY]:               The answer as proffered would be no. That’s all
    the questions I have of Mr. Gay.
    On March 6, 2014, the court filed an order reflecting its partial grant of FOP’s motion
    to enforce. The March 6 order awarded FOP, “pursuant to the ‘make whole’ provision of the
    Arbitrator’s Award,” damages of $1,413,120.81, but declined to award any attorney’s fees
    or pre-judgment interest. In a footnote, the court explained:
    [FOP] is not entitled to compound pre-judgment interest. Med. Mut. Liab. Ins.
    Soc. of Maryland v. Davis, 
    389 Md. 95
    , 112 (2005), Walker v. Acting Dir.,
    Dep’t of Forests & Parks, 
    284 Md. 357
    , 367 (1979). The Court is unable to
    determine an amount for simple pre-judgment interest because [FOP’s] Exhibit
    4 computes pre-judgment interest compounded monthly. Accordingly, the
    Court cannot award pre-judgment interest to [FOP].
    Both the County and FOP noted appeals to this Court following entry of the March
    6 order.4
    On February 18, 2014, FOP filed a motion “to clarify amount of prejudgment
    interest.” FOP informed the court that it agreed that, to the extent FOP was owed any
    4
    FOP filed a Line in this Court on July 31, 2014, dismissing its cross-appeal.
    54
    prejudgment interest, it was owed only simple interest, not interest compounded in any
    manner. FOP attached to the motion an affidavit of its expert economist, Dr. Amy McCarthy,
    in which Dr. McCarthy averred that she had “recalculated the interest owed to the affected
    retirees based on the amounts reflected in the spreadsheet provided by the County to the
    FOP,” and that, using the annual rate of 6% simple interest, the retirees were owed
    $213,446.47 in prejudgment interest. A spreadsheet showing the supporting calculations was
    attached to Dr. McCarthy’s affidavit.
    On February 26, 2014, the County filed its opposition to the motion. On March 14,
    2014, FOP filed a motion to reconsider the March 6 order, pointing to the simple-interest
    calculations of Dr. McCarthy as sufficient evidence of the amount, and asking the court to
    perform the “ministerial task” of awarding the properly-computed pre-judgment interest
    which FOP claimed. FOP additionally noted that it would not object to the County deposing
    or otherwise questioning Dr. McCarthy. The County filed its supplemental opposition on
    March 28, 2014. On April 28, 2014, the court granted FOP’s motion for reconsideration, and
    entered an amended judgment awarding FOP the original judgment amount of $1,413,120.81,
    plus pre-judgment interest of $213,446.47, for a total judgment of $1,626,567.28. On April
    25, 2014, the County noted its appeal of the amended judgment order.5
    5
    The amended order was signed on April 17, 2014, but not docketed until April 28,
    2014. However, counsel were copied on the order once it was signed, which may explain
    how the County was able to note an appeal to this Court on April 25, 2014. See Maryland
    Rule 8-602(d), which deems a notice of appeal filed after the rendering of a judgment, but
    before the judgment is docketed, as being filed on the same day as the docket entry of the
    judgment.
    55
    Meanwhile, on April 15, 2014, FOP filed a petition for an order of constructive civil
    contempt against the County, County Executive Kevin Kaminetz, Director of the Office of
    Budget & Finance Keith Dorsey, and County Administrative Officer Fred Homan.6 In its
    contempt petition, FOP noted that it had been several months since the County’s liability had
    been determined; the County’s attempts to have the matter stayed by the circuit court and
    this Court had failed; and the County’s refusal to make payment in accordance with the
    court’s orders left FOP with no other option than to ask that the officials who were refusing
    to pay be held in contempt. On April 15, the circuit court issued a show cause order,
    directing the County and the named officials to appear at a hearing on June 26, 2014, and
    “show cause why the Court should not hold each in contempt and/or impose sanctions,
    including incarceration.”
    On April 14, 2014, the County filed a response to the petition for an order of
    constructive civil contempt.7     It also filed an answer to the petition for an order of
    6
    This was FOP’s second petition for order of constructive civil contempt. On October
    4, 2013, it filed a petition for order of constructive civil contempt against the County and
    Messrs. Kamenetz and Dorsey. The County filed an opposition that was docketed on
    October 2, 2013 — before FOP’s petition was even docketed. It appears that FOP’s petition
    had been transmitted to the County’s counsel on September 20, 2013, which may explain
    why the opposition was docketed before the petition it opposed was docketed. Nevertheless,
    FOP voluntarily withdrew that first petition for order of constructive civil contempt in open
    court on February 6, 2014.
    7
    The docket entries reflect that FOP filed its second petition for order of constructive
    civil contempt against the County and Messrs. Kamenetz, Dorsey, and Homan on April 15,
    2014, but the County filed its opposition to that petition on April 14, 2014. The date on the
    signature page of FOP’s petition is March 28, 2014, as is the date on the letter from FOP to
    the Clerk of the Circuit Court for Baltimore County that accompanied the petition. We
    56
    constructive civil contempt on April 28, 2014, incorporating by reference its earlier-filed
    response to that petition. On April 28, 2014, the County also filed a motion to quash the
    show cause order, and asked the court to exempt the individual County officials from having
    to personally appear on June 26.
    On May 16, 2014, FOP filed an opposition to the motion to quash, and on May 28,
    2014, the court denied the County’s motion to quash.
    On May 30, 2014, the County filed a certification of compliance with outstanding
    court orders, representing that it had, under protest, paid the judgment amount of
    $1,413,120.81; $213,446.47 in pre-judgment interest; $55,348.68, representing the subsidy
    for the months of April and May of 2014; $14,260.32 in post-judgment interest at 10% per
    annum, accounting from the docketing of the court’s amended judgment on April 28, 2014,
    through May 30, 2014; and $227.70 in post-judgment interest for the April 2014 subsidy, for
    a grand total of $1,696,403.98. Additionally, the certification contained an affirmation of
    Keith Dorsey that the subsidy rates had been reset as ordered by the court in its November
    5, 2013, order. The rest of the certification made clear that the County made these payments
    “solely as a result of the coercion and duress imposed upon it,” and that it reserved all of its
    appeal rights. A second supplemental certification followed on June 10, 2014, representing
    surmise that the County’s April 14 opposition to FOP’s yet-to-be-docketed petition was
    triggered by the County’s receipt of FOP’s petition sometime between March 28 and April
    14.

    that another payment of $20,209.56 had been made by the County to account for prejudgment
    interest from February 1, 2014, through April 28, 2014.
    In the present appeal, the County challenges the circuit court’s orders of November
    5, 2013 (ordering the County to reset the retiree health insurance split to the rate in effect at
    the time of retirement); March 6, 2014 (entering judgment in favor of FOP for
    $1,413,120.81); and April 28, 2014 (entering an amended judgment in favor of FOP for
    $1,626,576.28).
    DISCUSSION
    I.     The Law of the Case doctrine
    The law of the case doctrine provides generally that, “[o]nce an appellate court has
    answered a question of law in a given case, the issue is settled for all future proceedings”
    between the litigants. Stokes v. American Airlines, Inc., 
    142 Md. App. 440
    , 446 (2002). The
    doctrine “prevents trial courts from dismissing appellate judgment and re-litigating matters
    already resolved by the appellate court.” 
    Id.
     “The function of this doctrine is to prevent
    piecemeal litigation.” Fid.-Balt. Nat’l Bank & Trust Co. v. John Hancock Mut. Life Ins. Co.,
    
    217 Md. 367
    , 371-72 (1958).
    In Reier v. State Dept. of Assessments and Taxation, 
    397 Md. 2
    , 21 (2007), the Court
    of Appeals described the doctrine by quoting the following passage from Fid.-Balt Nat’l
    Bank & Trust Co.:
    It is the well-established law of this state that litigants cannot try their
    cases piecemeal. They cannot prosecute successive appeals in a case that raises
    58
    the same questions that have been previously decided by this Court in a former
    appeal of that same case; and, furthermore, they cannot, on the subsequent
    appeal of the same case raise any question that could have been presented
    in the previous appeal on the then state of the record, as it existed in the
    court of original jurisdiction. If this were not so, any party to a suit could
    institute as many successive appeals as the fiction of his imagination could
    produce new reasons to assign as to why his side of the case should
    prevail, and the litigation would never terminate. Once this Court has
    ruled upon a question properly presented on an appeal, or, if the ruling
    be contrary to a question that could have been raised and argued in that
    appeal on the then state of the record, as aforesaid, such a ruling becomes
    the ‘law of the case’ and is binding on the litigants and courts alike, unless
    changed or modified after reargument, and neither the questions decided
    nor the ones that could have been raised and decided are available to be
    raised in a subsequent appeal.
    
    217 Md. at 371-72
     (emphasis added).
    In this appeal, the County argues that the law of the case doctrine does not apply
    because it is now challenging the “enforceability of the recent orders,” not the “legally
    distinct issue[ ] . . . of the legal validity of the award itself.” The County contends that the
    Court of Appeals never decided any issue related to enforceability. The County again
    contends that the nine questions it presented to this Court in its 2011 appeal “were never
    addressed by the Court of Special Appeals or the Court of Appeals.” It claims the Court of
    Appeals’s refusal to grant the County’s request to remand the case to this Court for
    consideration of the nine questions it raised in its previous appeal “effectively denied the
    County’s right of appeal which is guaranteed by Courts & Judicial Proceedings Article, § 12-
    301.”8 The County contends that the circuit court’s application of the law of the case
    8
    Md. Code, Courts & Judicial Proceedings Article (1973, 2013 Repl. Vol.) (“CJP”),
    § 12-301 provides:
    59
    doctrine was “patently erroneous in light of the Court of Appeals holding in Garner v.
    Archers Glen Partners, Inc., 
    405 Md. 43
     (2008).” The County is incorrect, and its reliance
    on Garner is misplaced.
    In Garner, a group of citizens filed a petition for judicial review in the Circuit Court
    for Prince George’s County, contesting the approval, by the Prince George’s County
    Planning Board, of a preliminary plan. The circuit court affirmed the Planning Board, and
    the citizens appealed to this Court. In an unreported opinion (“Archers Glen I”), this Court
    held that the Planning Board “failed to articulate sufficiently the findings in support of its
    conclusion that the Preliminary Plan conformed to the recommendations of the Master Plan.”
    
    405 Md. at 49
    . This Court vacated the circuit court’s affirmance of the Planning Board and
    directed that the case be remanded to the Planning Board for further proceedings, but first,
    “[i]n an attempt to avoid the expense and delay of additional appeals,” we offered for
    guidance dicta “discussing the potential legal effect to be accorded the General Plan in the
    subdivision process[.]” 
    Id. at 52
    . On remand, the Planning Board again approved the
    Preliminary Plan, and the citizens again contested that approval by filing a petition for
    judicial review. When the circuit court considered the second petition for judicial review,
    Except as provided in § 12-302 of this subtitle, a party may appeal from
    a final judgment entered in a civil or criminal case by a circuit court. The right
    of appeal exists from a final judgment entered by a court in the exercise of
    original, special, limited, statutory jurisdiction, unless in a particular case the
    right of appeal is expressly denied by law. In a criminal case, the defendant
    may appeal even though imposition or execution of sentence has been
    suspended. In a civil case, a plaintiff who has accepted a remittitur may cross-
    appeal from the final judgment.
    60
    it ordered the case remanded to the Planning Board for further fact-finding. The developer
    and the Planning Board appealed to this Court.
    In this second appeal, we reversed the circuit court’s remand order, and we filed a
    reported opinion.    Archers Glen Partners, Inc. v. Garner, 
    176 Md. App. 292
     (2007)
    (“Archers Glen II”.) One of the arguments the citizens made in Archers Glen II was that this
    Court’s discussion, in dicta, in Archers Glen I was “the law of the case,” and therefore, “the
    recommendations of the General Plan were binding on the Planning Board in considering and
    acting on the Preliminary Plan.” 
    405 Md. at 52
    . We held in Archers Glen II that the dicta
    in our earlier opinion was merely dicta that did not constitute the law of the case. The
    citizens appealed our decision in Archers Glen II, and the Court of Appeals affirmed, noting:
    “[I]t is clear that, in Maryland, dicta not adopted as a final determination may not serve as
    the binding law of the case.” 
    Id. at 57
    .
    By contrast, in the instant case, the Court of Appeals’s decision affirming the circuit
    court’s grant of summary judgment in favor of FOP was not mere dicta. It was a final
    determination that FOP was entitled, as a matter of law, to the judgment to enforce the
    arbitration award. That decision necessarily embraced and resolved all of the issues that the
    County raised, as well as any other issues that were then available to raise, challenging the
    validity of the arbitration award.
    In the previous appeal of this case, in its opinion ruling that the circuit court’s order
    to enforce the arbitration award was affirmed, the Court of Appeals stated:
    61
    Thus, the Circuit Court would be legally correct in granting
    summary judgment in FOP's favor, if (1) it reviewed the arbitrator's findings
    under a proper standard of review and (2) if FOP was entitled to judgment
    as a matter of law.
    As the arbitrability of FOP's grievance was a decision to be initially
    made by the arbitrator, that decision was subject to the same deferential
    standard of review as the arbitrator's findings on the merits. Thus, the Circuit
    Court needed to make sure that both the arbitrator's findings (1) that FOP's
    grievance was arbitrable and (2) that FOP was entitled to relief did not
    constitute a “palpable mistake of law or fact apparent on the face of the award
    or a mistake so gross as to work manifest injustice.” Prince George's Cnty.
    Educators' Ass'n, 309 Md. at 105, 522 A.2d at 941 (quotation marks omitted).
    Because the Circuit Court was unsure what standard to apply in reviewing the
    arbitrator's arbitrability finding, the Circuit Court subjected that finding to both
    a deferential and non-deferential standard of review. As for the award itself,
    the court “awarded great deference” to the arbitrator's findings. Accordingly,
    the Circuit Court applied a proper standard of review in both instances.
    We now look to the arbitrator's findings to determine whether the
    Circuit Court was legally correct in granting summary judgment in FOP's
    favor. The arbitrator began his opinion by acknowledging the County's
    argument about the supposedly preclusive effect of the MOU's expiration on
    the arbitrability of FOP's grievance. Relying on Nolde[9] and Litton [10] , the
    arbitrator responded to the County's challenge by stating that “[t]he end of a
    labor contract, however, does not always signal the death of negotiated rights
    thereunder, including the right to have a dispute over that matter resolved
    through arbitration.” The arbitrator then discussed Nolde and Litton for their
    vesting principles and concluded that “the ultimate question is whether the
    retiree rights at issue may be considered vested and thus capable of continuing
    enforcement.”
    In the arbitrator's view, the question of vesting “is answered directly by
    the unequivocal language of the MOUs: The statement that ‘the health

    62
    insurance subsidy in place at the time of retirement shall remain in effect until
    the retiree becomes eligible for Medicare’ is subject to no interpretation other
    than that here proposed by the FOP.” He continued, “[w]hen the parties
    bargained this language, they made a binding promise to retirees that the
    subsidy would remain at whatever level existed at their retirement. That is a
    vested right, and it was not, and could not be, changed by the [subsequent]
    negotiations....” The arbitrator concluded: “[o]fficers who retired on or after
    February 1, 1992 and before July 1, 2007 have a vested right to retain the
    health insurance split applicable to them as active officers at the time of their
    retirement.”
    The County attacks the arbitrator's findings on several fronts. In
    addition to arguing against the application of Nolde and Litton to this case, the
    County suggests that the “Arbitrator acknowledged, but did not address, the
    County's argument that all obligations under the Agreement expired, including
    both the healthcare obligations and the independent obligation to arbitrate.”
    According to the County, this alleged failure to consider whether the
    arbitration clause had expired gives basis to vacate the arbitration award not
    only for a palpable mistake in law, but also for failure “to consider all matters
    submitted.”
    The County also argues that the healthcare subsidy was not a vested
    right. Here, the County asserts that “[t]here is no ‘vested right’ to future health
    insurance benefits and subsidies in the expired FY 2007 MOU, based on
    evidence, long-standing practice, and applicable law.” In support of this
    statement, the County mentions the Labor Commissioner's testimony, where
    he stated that “there is no vested right to health insurance benefits and there
    never has been such a right in Baltimore County.” The County also points out
    that “there is no statutory requirement that County employees be provided with
    health care benefits.”
    The County's arguments are unavailing. First, we agree with FOP
    that “as a corollary to his express findings that the right had vested, and as a
    necessary precondition to his granting the grievance, the arbitrator necessarily
    determined that the arbitration clause was enforceable and that the grievance
    was arbitrable.” The arbitrator's consideration of the arbitrability of the dispute
    and the merits of the case illustrates the interconnectedness of these two issues
    in cases where arbitrability depends on the interpretation of the underlying
    agreement. Having found that the retirees were entitled to the health-insurance
    premium split in effect at the time of their retirement, the arbitrator necessarily
    63
    also found, by implication, that the arbitration clause survived the MOU's
    expiration, and the dispute was arbitrable. See Nolde, 
    430 U.S. at 249
    , 
    97 S.Ct. at 1071
     (“[I]n determining the arbitrability of the dispute, the merits of the
    underlying claim for severance pay are not before us. However, it is clear that,
    whatever the outcome, the resolution of that claim hinges on the interpretation
    ultimately given the contract clause providing for severance pay.”); Litton, 
    501 U.S. at
    205–06, 
    111 S.Ct. at 2225
     (“A postexpiration grievance can be said to
    arise under the contract only where it involves facts and occurrences that arose
    before expiration, where an action taken after expiration infringes a right that
    accrued or vested under the agreement, or where, under normal principles of
    contract interpretation, the disputed contractual right survives expiration of the
    remainder of the agreement.”).
    Second, like the Circuit Court, we see no reason to disturb the
    arbitrator's finding of vesting. The County's arguments on the lack of county
    employees' statutory entitlement to health care based on Commissioner Gay's
    testimony simply miss the point. The arbitrator found that the rights had
    vested based on his interpretation of the underlying MOU, which stated
    that “the health insurance subsidy in place at the time of retirement shall
    remain in effect until the retiree becomes eligible for Medicare.” We do not
    think that the arbitrator's reading of this clause as a “binding promise”
    constituted a “manifest disregard of the law” or resulted in “manifest
    injustice.” Prince George's Cnty. Educators' Ass'n, 309 Md. at 105, 522 A.2d
    at 941. On the contrary, we agree with the Circuit Court that the
    arbitrator's interpretation of this language was consistent with the
    objective theory of contract interpretation that Maryland adheres to,
    under which courts give primary effect to the terms of the agreement.
    Cochran v. Norkunas, 
    398 Md. 1
    , 16, 
    919 A.2d 700
    , 709 (2007).
    In any event, the arbitrator's findings are awarded a great deal of
    deference and should not be disturbed, unless the arbitrator demonstrates
    a “manifest disregard of the law ... beyond and different from a mere
    error in the law or failure on the part of the arbitrator[ ] to understand
    or apply the law.” Prince George's Cnty. Educators' Ass'n, 309 Md. at 102,
    522 A.2d at 939. Since we see no such mistakes here, we conclude that the
    Circuit Court correctly determined that FOP was entitled to judgment as
    a matter of law. Thus, we reverse the judgment of the Court of Special
    Appeals.
    429 Md. at 561-64 (emphasis added).
    64
    Plainly, the Court of Appeals affirmed the circuit court’s conclusion that the grievance
    was arbitrable, which means that it necessarily agreed that the grievance was properly
    pursued by FOP on behalf of the retirees — despite the County’s insistence that retirees are
    not employees entitled to bring a grievance — and that the grievance was timely. Summary
    judgment would not have been properly granted to FOP if it were otherwise.
    Similarly, the Court of Appeals could have remanded, but did not remand, the case
    to this Court for further consideration of the “nine questions” the County raised in the 2011
    appeal. In a motion for reconsideration, the County expressly asked the Court of Appeals to
    remand for further consideration, and made the following arguments — a portion of which
    we quoted above — in support of the remand requests:
    Compounding its error in nullifying a negotiated agreement, the Court
    [of Appeals] either mistakenly or intentionally refused the County’s request to
    remand this case to the [Court of Special Appeals] for consideration of the
    issues which the County had raised, but which were not addressed by that
    Court. (See the issues listed in the [Court of Special Appeals’s] Unreported
    Opinion at note 1, reproduced at Petitioner’s App. 217-218). Thus, the County
    has been denied the right of appeal which is guaranteed by Courts & Judicial
    Proceedings Article, § 12-301 from the final judgment entered by the Circuit
    Court for Baltimore County.
    The Court’s decision to remand to the [Court of Special Appeals] “with
    directions to affirm the judgment of the Circuit Court for Baltimore County”
    is inconsistent with its many prior decisions remanding “to the intermediate
    appellate court for consideration of undecided issues.”
    ***
    Of great practical consequence to the County, there has been no review
    of the following issue which was raised by the County in its Brief in the [Court
    of Special Appeals]:
    65
    Contrary to law and public policy, the arbitrator’s award
    usurps the power of the Baltimore County Executive and the
    Baltimore County Council to enact a budget which provides for
    health insurance and health insurance subsidies pursuant to the
    terms negotiated by the HCRC, FOP Lodge 4's bargaining agent.
    The Arbitrator in this case had no power or authority to order the
    County Executive and County Council to fund a split different from the
    negotiated split enacted into law as part of the FY 2008, 2009, 2010, 2011
    and 2012 budgets, to order the County Executive and County Council to
    reset the split at 85/15 in any future budgets, or to “make whole” affected
    retirees for increased premium amounts not budgeted by the County
    Executive and County Council.
    If this Court’s decision is allowed to stand, and this matter is remanded
    to the [Court of Special Appeals] with directions to affirm the judgment of the
    Circuit Court for Baltimore County, the Arbitrator’s affirmed award will be
    unenforceable, since there have been no funds appropriated through the
    executive budget process to afford the relief capriciously dictated by the
    Arbitrator.
    (Emphasis added.)
    Notwithstanding these arguments, the Court of Appeals denied the County’s motion
    for reconsideration, and left in place its order to affirm the judgment of the circuit court.
    “[O]nce an appellate court rules upon a question presented on appeal, litigants and lower
    courts become bound by the ruling, which is considered to be the law of the case.” Scott v.
    State, 
    379 Md. 170
    , 183-84 (2004). As the Court of Appeals made plain in Fid. Balt. Nat’l.
    Bank, 
    supra,
     
    217 Md. at 372
    , “neither the questions decided [by the appellate courts] nor the
    ones that could have been raised and decided are available to be raised in a subsequent
    appeal.” (Emphasis added.)
    66
    In the Court of Appeals’s opinion in Garner v. Archers Glen Partners, Inc., supra,
    
    405 Md. at 56
    , it quoted the following from Turner v. Housing Auth. of Balt., 
    364 Md. 24
    ,
    34 (2001):
    It is well settled that the law of the case doctrine does not apply when one of
    three exceptional circumstances exists: the evidence on a subsequent trial was
    substantially different, controlling authority has since made a contrary decision
    on the law applicable to such issues, or the decision was clearly erroneous and
    would work a manifest injustice.
    But none of those “exceptional circumstances” is present here.
    Moreover, the public policy arguments about enforceability that the County complains
    have never been addressed were, in fact, presented to and ruled on by the circuit court before
    the first round of appeals. In the circuit court’s memorandum opinion and order granting
    summary judgment in favor of FOP, the court noted that one of the County’s arguments was
    that “the Arbitrator had no authority to rewrite the FY 2008 MOU and order the County to
    reset the previous 85/15 split for the retirees in question.” As noted above, the circuit court
    addressed the County’s public policy arguments as follows:
    Lastly, the County contends that [the Arbitrator] exceeded his authority
    by effectively rewriting the health care subsidy provisions negotiated by the
    HCRC on behalf of the FOP for the FY 2008 MOU and by ordering the
    County to maintain the 85/15 subsidy split for officers that retired after
    February 1, 1992 and before July 1, 2007.
    Specifically, the County argues that [the Arbitrator] exceeded his
    authority as set forth [in] Section 8.3, Step 4 of the FY 2007 MOU. That
    section provides:
    The arbitrator shall have no authority to add to, detract from,
    alter, amend or modify any provision of this Memorandum of
    67
    Understanding or any rules or regulations of any agency of the
    County, or establish or alter any wage rate or wage structure.
    The County further asserts that the Award was contrary to the Budgetary and
    Fiscal Procedures set forth in the Baltimore County Charter and the Baltimore
    County Code, which state the County Executive and County Council are
    responsible for enacting a budget and appropriating funds needed to run the
    County, including health care subsidies. [The Arbitrator’s] Award, the County
    argues, usurped these powers by ordering the County to maintain and fund the
    85/15 subsidy split.
    The FOP counters that [the Arbitrator’s] Award concerned only the
    interpretation and enforcement of compensation terms that were previously set,
    and as such, does not usurp either the legislative or executive power of the
    County. The FOP points to the distinction between grievance arbitration,
    which uses a neutral third party to resolve a dispute over the interpretation of
    an existing contract, and interest arbitration, which uses a neutral third party
    to set the terms of a new contract. Under the prevailing case law, argues the
    FOP, grievance arbitration does not involve the delegation of legislative
    authority because the arbitrator is acting in [a] judicial capacity rather than a
    legislative one. “The authority to interpret an existing contract, therefore, does
    not constitute legislative authority, and the nondelegation principle is not
    implicated in grievance arbitration.” [City & County of Denver v. Denver
    Firefighters Local No. 858, 
    664 P.2d 1032
    , 1038 (Colo. 1983).]
    The Court agrees with the FOP’s position. The County and the FOP
    agreed to submit “any dispute concerning the application or interpretation of
    the terms of [the FY 2007] Memorandum of Understanding” to binding
    arbitration. The grievance submitted to [the Arbitrator] concerned the
    interpretation of Section 7.3(c), a contract term that had already existed and
    had been bargained for by the parties. In resolving the grievance, [the
    Arbitrator] did no more than what was required of him – to interpret the
    disputed contract language in accordance with the facts presented and
    applicable law. Therefore, the Court finds that [the Arbitrator] did not exceed
    his authority i[n] reaching his Award.
    (Footnotes omitted.)
    68
    We are not persuaded by the County’s argument that the law of the case doctrine
    should not apply because the public policy arguments it made previously went to the merits
    of the award, whereas the present arguments attack the enforceability of the award. The
    arbitrator’s award expressly directed the County to take the actions the FOP asked the circuit
    court to compel in the motion to enforce. The award stated:
    The County is directed to rescind its modification, to reset the contribution
    split applicable to these officers to 85/15, to continue that split so long as, by
    the terms of the language, these officers remain eligible and to make whole
    affected retirees for increased premium amounts improperly charged to them
    since September 1, 2007.
    The County was obligated to assert all of its arguments that might support vacating
    the award, including all of its arguments against enforcement of the award, during the first
    round of circuit court proceedings. When the Court of Appeals confirmed in 2012 that FOP
    was entitled to the grant of summary judgment in its favor, all of the public policy arguments
    the County had made, or could have made, about enforceability of the arbitration award were
    resolved against the County. Consequently, the arguments that the County makes on this
    appeal related to enforceability — including its questions presented 1, 2, and 3 — have
    already been conclusively resolved by the Court of Appeals’s prior ruling in favor of FOP.
    We will not consider these questions further.
    Similarly, the County’s arguments about the timeliness of the initial grievance and the
    right of the retirees to file a grievance — appellant’s questions presented 5 and 6 — have
    also already been conclusively resolved. The circuit court determined, as a predicate to its
    69
    August 17, 2010, grant of summary judgment in favor of FOP, that the grievance was timely
    filed and that the retirees had standing to pursue it. This finding was necessarily affirmed
    by the Court of Appeals’s 2012 ruling affirming the grant of summary judgment in FOP’s
    favor.
    II. The balance of the County’s contentions on this appeal
    Having held that the County’s questions presented 1, 2, 3, 5, and 6 are not before us
    for review due to the law of the case doctrine, we turn now to the County’s remaining
    contentions, which raise issues that arose for the first time after the remand.
    First, in question 4, the County asks whether the show cause order’s threat of
    incarceration was “an unconstitutional exercise of judicial power calculated to coerce an
    appropriation or illegal payments in violation of the separation of powers doctrine.” Because
    the circuit court never ordered the incarceration of any County official, this issue is moot.
    Suter v. Stuckey, 
    402 Md. 211
    , 219 (2007) (“A case is moot when there is . . . no longer an
    effective remedy the Court could grant.”). We decline to render an advisory opinion on the
    constitutional question.
    Next, in question 7, the County asks whether the circuit court’s “award of injunctive
    relief and damages to FOP was clearly erroneous, because FOP did not sustain any harm or
    damages as a result of the reduced subsidy rates.” In support of its claim that the court erred,
    the County cites one case: L.W. Wolfe Enterprises, Inc. v. Maryland National Golf, L.P., 
    165 Md. App. 339
    , 343 (2005). But L.W. Wolfe is a case about a mechanic’s lien that a
    70
    subcontractor wanted to obtain against an entire golf course as a remedy for unpaid work the
    subcontractor did on certain cart paths at the golf course. The trial court found that the
    subcontractor was not entitled to the mechanic’s lien on the entire property because the work
    it did on the cart paths was repair, not new construction. L.W. Wolfe’s applicability to the
    issues presented in the instant case is not readily apparent.
    The circuit court action in this case began when the County filed a motion to vacate
    the arbitrator’s award. That motion recited the basic facts, including that FOP filed a class
    grievance on September 14, 2007, complaining, on behalf of its affected members, about the
    altered subsidy split. The motion to vacate made numerous arguments, but never asserted
    that FOP lacked standing to pursue a grievance on behalf of its members. Moreover, the
    FOP’s motion to enforce the arbitration award provided an adequate basis for the court to
    enter the order for payment of compensation contemplated by the arbitrator’s ruling.
    The County asks in question 8 whether the circuit court erred in refusing to allow its
    witnesses to testify, at the damages hearing, about their thoughts regarding whether there was
    any merit to the underlying grievance in the first instance, or whether certain appropriations
    had been made. The court sustained FOP’s objections to these questions, and the County was
    allowed to proffer what its witnesses’ answers would be, which were generally that the
    grievance was improper and the retirees FOP represents were not entitled to any relief. But
    a damages hearing was not an appropriate forum to relitigate the validity of the underlying
    award. Consequently, we perceive no error in the refusal of the court to permit the County’s
    71
    witnesses to give irrelevant testimony. See Maryland Rule 5-402 (“Evidence that is not
    relevant is not admissible.”)
    Finally, in question 9, the County asks whether FOP was entitled to pre-judgment
    interest. The County argues that the circuit court erred in relying on the affidavit of Dr. Amy
    McCarthy, FOP’s economist expert, and in entering an amended judgment that awarded pre-
    judgment interest. The County complains that Dr. McCarthy’s affidavit was hearsay not
    within any exception, and that the court’s post-hearing reliance on it prevented the County
    from cross-examining Dr. McCarthy. The County complains further that, in any event, FOP
    was not entitled to pre-judgment interest because “there is no entitlement to prejudgment
    interest on unliquidated claims.” The County’s arguments fail.
    An unliquidated claim is “one, the amount of which has not been fixed by agreement
    or cannot be exactly determined by the application of rules of arithmetic or of law.” 3
    S AMUEL W ILLISTON & R ICHARD A. L ORD, A T REATISE ON THE L AW OF C ONTRACTS § 7:34
    (4th ed. 2008). The County complains that the amount it owed the retirees in damages was
    unliquidated. But the County’s own evidence proved otherwise. At issue was the County’s
    liability, vel non, for its decision to discontinue the 85/15 subsidy split it had paid for retirees
    between 1992 and 2007.          The higher amounts charged the retirees were specifically
    ascertainable amounts. Although the total amounts were not known by FOP, these amounts
    were readily quantifiable, and were not unliquidated. The arbitrator, the circuit court, and
    the Court of Appeals all found that the County had made a vested benefit agreement to
    72
    maintain an 85/15 subsidy split for a specifically identifiable group of retirees until each
    became eligible for Medicare. Once liability was determined, the amount of damages was
    readily ascertainable from the County’s own records. It depended on four fixed, known
    numbers: the total premium cost of the insurance, the amount the County should have been
    charging the retirees (15%), the amount the County had charged the retirees post-September
    1, 2007, and the difference between what the County should have been charging and what
    it had actually collected from those retirees. The County provided the spreadsheet showing
    all these numbers, and FOP’s expert witness, Dr. McCarthy, explained the numbers to the
    court at the damages hearing. The court had previously determined that FOP was entitled
    to prejudgment interest; the principal amount on which that interest was to be calculated was
    ascertainable (but growing each month); and therefore the court was permitted to perform
    the ministerial task of determining the amount of prejudgment interest due without convening
    another hearing. In the absence of any suggestion — either in the circuit court or on appeal
    — that Dr. McCarthy’s arithmetic was incorrect, we perceive no error in the circuit court’s
    reliance upon her computations.
    In Blue Cross & Blue Shield of Maryland, Inc. v. Chestnut Lodge, Inc., 
    81 Md. App. 149
     (1989), this Court quoted with approval from Affiliated Distillers Brands Corp. v. R.W.L.
    Wine & Liquor Co., Inc., 
    213 Md. 509
    , 516 (1957) (citations omitted):
    The law in Maryland with reference to interest is well settled. The general rule
    is that interest should be left to the discretion of the jury, or the Court when
    sitting as a jury. However, this general rule is subject to certain exceptions that
    are as well established as the rule itself. Among the exceptions are cases on
    73
    bonds, or on contracts, to pay money on a day certain, and cases where the
    money has been used. If the contractual obligation be unilateral and is to pay
    a liquidated sum of money at a certain time, interest is almost universally
    allowed from the time when its payment was due.
    Here, FOP’s entitlement to prejudgment interest was clear. All that remained to be
    done was the math. In Ali v. CIT Technology Financing Services, Inc., 
    188 Md. App. 269
    (2009), we remanded a case because we could not discern, from the record, how the trial
    court arrived at its prejudgment interest award. We noted, however, that “we are unaware
    of any case requiring the trial judge to disclose its method of calculating prejudgment
    interest.” Id. at 298. That is not an issue here. In this case, the County provided
    spreadsheets showing the subsidy amount being paid, the subsidy amount that should have
    been paid, what the retirees were actually charged, and the difference. Dr. McCarthy
    performed the arithmetic and testified at the damages hearing. The County cross-examined
    her at the hearing and questioned her at her deposition.
    FOP points to a case from the United States Court of Appeals for the Fourth Circuit,
    Kosnoski v. Howley, 
    33 F.3d 376
     (4th Cir. 1994), in support of its contention that the circuit
    court in this instance was permitted, without holding another hearing, to perform the task of
    computing the amount of already-awarded prejudgment interest, as such a computation
    would involve only plugging numbers into a formula, not revisiting the merits of the award
    itself. In its reply brief, the County cited no cases in opposition to this notion. We find the
    reasoning of the 4th Circuit in Kosnoski persuasive. There, Kosnoski, the owner of two
    companies, agreed with Howley that, if Howley found a buyer for his companies, Kosnoski
    74
    would pay Howley a finder’s fee of 5%. Howley found a buyer, and Kosnoski paid the 5%
    finder’s fee as to one of the companies he sold, but refused to pay Howley his finder’s fee
    relative to the other company. Kosnoski sued Howley and sought to have their arrangement
    declared unenforceable under West Virginia law. Howley counterclaimed, seeking his 5%
    finder’s fee on the second company. The United States District Court for the Southern
    District of West Virginia sided with Howley, and ordered Kosnoski to pay Howley the 5%
    finder’s fee he was due, “plus any appropriate pre-judgment and post-judgment interest at
    the legal rate.” 
    Id. at 377
    .
    Kosnoski appealed to the 4th Circuit, and lost. He then filed a motion for rehearing
    or rehearing en banc, which was denied. Kosnoski still refused to pay, and asserted that the
    District Court had not set the start date from which the interest would accrue. Howley filed
    a motion to fix interest, which Kosnoski argued was really a motion to alter or amend under
    Federal Rule of Civil Procedure 59(e). Because the motion had been filed more than ten days
    after the entry of judgment, Kosnoski argued it was untimely and had to be denied. Howley
    argued that it was not a motion to alter or amend because the District Court had already
    determined that he was entitled to prejudgment interest, and his motion merely asked the
    judge to do the math and set the amount. The District Court agreed with Howley.
    Kosnoski again appealed, and the 4th Circuit again ordered him to pay Howley the
    prejudgment interest that was due. Pointing out that it had already been determined that
    75
    Howley was entitled to prejudgment interest, the 4th Circuit held that the District Court was
    permitted to fill in the blanks as to the precise amount due:
    [S]uch a court does not revisit the merits of the question [regarding entitlement
    vel non to prejudgment interest] and certainly does nothing that can be called
    “reconsidering” the matter. Instead, the court is asked to perform a completely
    ministerial task by plugging the time period, the interest rate and the judgment
    amount into a preset formula and announcing the result.
    The facts of this case demonstrate the ministerial nature of the court’s
    responsibility: both parties understood that interest had been awarded; both
    parties understood that West Virginia law set the rate of prejudgment interest
    at ten percent; and both parties understood the time frame for computation.
    The court’s only task was to do the calculation and make the amount official.
    We simply do not believe that by performing this function the court altered or
    amended the judgment. Rather, we are persuaded that the court, in
    undertaking such a task, merely supplies a figure to the judgment, the amount
    of which had already been fixed at the time of the entry of judgment. This
    omission is the type of error that is properly within the scope of [Fed.] Rule
    [Civ. Pro.] 60(a).[11]
    ***
    The task required of the court was completely ministerial, and involved
    the mere application of a series of facts previously determined to a set formula
    in order to elucidate a part of the judgment order that, while providing notice
    to all as to their positions, was sufficiently inexact to allow Kosnoski to
    attempt not to comply.
    
    Id. at 379
    .
    11
    Federal Rule of Civil Procedure 60(a) states:
    (a) Corrections Based on Clerical Mistakes; Oversights and Omissions.
    The court may correct a clerical mistake or a mistake arising from oversight
    or omission whenever one is found in a judgment, order, or other part of the
    record. The court may do so on motion or on its own, with or without notice.
    ...
    76
    The reasoning in Kosnoski applies with equal force here. A calculation of simple
    interest at the rate of 6% for pre-judgment interest — or 10% for post-judgment interest —
    on a fixed sum is a ministerial task and one for which the court did not need to convene a
    new hearing.
