    No. M2008-01733-COA-R12-CV - Filed July 21, 2010
    The City of Chattanooga has appealed the decision by the Tennessee Regulatory Authority
    establishing a rate for the appellee, Tennessee American Water Company. The Tennessee
    American Water Company filed a Motion to Dismiss on the grounds that the issues before

    OPINION
    This appeal is brought pursuant to the Tennessee Uniform Administrative Procedures
    Act, Tenn. Code Ann. § 4-5-322(b)(1)(B)(iii)1 and is from a utility rate-making case decided
    by the Tennessee Regulatory Authority (TRA). The City of Chattanooga, Tennessee (City)
    and the Consumer Advocate and Protection Division of the Office of the Attorney General
    and Reporter (CAPD) are the appellants and the TRA and Tennessee American Water
    Company (TAWC) are the appellees.
    The determinative issue is whether the appeal is moot and should be dismissed. Only
    the facts and procedural history pertinent to the mootness issue are considered.
    TAWC provided a brief overview of the ratemaking process in Tennessee in its
    memorandum in support of its motion to dismiss the appeal based on mootness which is
    helpful for the following procedural history.
    TAWC is a public utility that provides water services to customers in and around
    Chattanooga, Tennessee. As a public utility, TAWC is subject to both federal and state laws
    and administrative regulations. The laws and regulations pertinent to this case prohibit
    TAWC from raising the rates it charges its customers unless it files a petition with TRA and
    TRA concludes that the proposed rates are just and reasonable. See Tenn. Code Ann. § 65-5-
    103. All the rates and charges TAWC is entitled to charge customers must be set forth in
    tariffs filed by TAWC with TRA and TAWC can only charge the rates that are set forth in
    a filed and effective tariff. See Tenn. Code Ann. § 65-5-102; Tenn. Comp. R. & Regs. 1220-
    4-1-.03.
    In the event TAWC wants to implement a rate increase based on an increase in its
    expenses or investments, decreased revenues, or other reasons, it must file a revision to the
    existing tariffs and a petition to revise the existing rates. See Tenn. Code Ann. § 65-5-103;
    Tenn. Comp. R. & Regs. 1220-4-1-.03 to .06. TRA has the authority to suspend the proposed
    rate increase pending an investigation regarding whether the proposed rate increase is just
    and reasonable. See Tenn. Code Ann. § 65-5-103. TRA can also convene a contested case
    and allow interested parties to intervene in the matter to oppose the proposed rates. If,
    following the investigation or contested hearing, TRA authorizes a rate revision other than
    1
    Tenn. Code Ann. § 4-5-322 (b)(1)(b)(iii) provides that “[a] person who is aggrieved by any final
    decision of the Tennessee regulatory authority, or by a final decision of the state board of equalization in a
    contested case involving centrally assessed utility property assessed in accordance with title 67, chapter 5,
    part 13, shall file any petition for review with the middle division of the court of appeals”. This appeal was
    filed in the middle section of the court of appeals but was transferred to the eastern section.
    -2-
    the one requested by TAWC, TAWC must file a revised tariff that sets out the rates
    authorized by TRA. Once the revised tariffs become effective, TAWC can charge its
    customers the increased rates and the tariffs remain in effect until they are subsequently
    modified. See Tenn. Code Ann. § 65-5-103; Tenn. Comp. R. & Regs. 1220-4-1-.03 to .06.
    The 2006 Rate Case and Appeal
    In accordance with the above stated ratemaking process, TAWC filed a petition and
    revised tariffs on November 22, 2006 with TRA. The petition sought an increase in rates
    based on TAWC’s claim that the then existing rates did not provide sufficient revenue to
    cover all costs incurred in providing water service to its customers. TRA suspended the
    proposed tariffs, convened a contested case, and permitted the intervention of CAPD, the
    City and Chattanooga Manufacturers Association (CMA). Over four days in April of 2007,
    a hearing was held on the merits of TAWC’s requested rate increase, and one of TAWC’s
    claimed increases in costs considered at the hearing was its Management Fees. This issue
    is the basis for the underlying appeal herein. Management fees are the charges from a
    contractor to TAWC for services under a service company contract. The services relate to
    accounting, administration, communication, corporate secretarial, engineering, finance,
    human resources, information systems, operations, rates and revenue, risk management and
    water quality.
    On May 15, 2007, the TRA panel assigned to the 2006 Rate case voted to authorize
    a rate increase of approximately $4 million dollars. On May 17, 2007, TAWC filed its
    revised tariffs that showed the rate increase approved by TRA, which became effective on
    May 22, 2007 (2006 Rate Case Tariffs). The 2006 Rate Case Tarriffs indicate they are the
    eighth revision of the tariffs and that they replace the seventh revision. The 2006 Final Order
    was not issued until more than a year later, on June 10, 2008. The 2006 Rate Case then was
    ripe for appeal.
    On August 8, 2008, the City filed its Petition for Direct Review of Administrative
    Proceedings of the 2006 Rate Case with this Court. The City indicated in the Petition that
    it intended to challenge TRA’s decision on the issue of the amount of management fees paid
    by TAWC to its service company, the amount of the overall rate and the soundness of the
    2006 Final Order based on the requirements for final orders found in Tenn. Code Ann. § 4-5-
    314. As to the management fee issue, the City claimed TRA failed to apply the appropriate
    statutory burden of proof when it failed to require TAWC to show that its management fees
    were just and reasonable and that the rate increase based on the management fees was just
    and reasonable. See Tenn. Code Ann. §§ 65-5-103(a)2 and 65-2-1093 and Tenn. Comp. R.
    2
    Tenn. Code Ann. § 65-5-103(a) provides that “[w]hen any public utility shall increase any existing
    individual rates, joint rates, tolls, fares, charges, or schedules thereof, or change or alter any existing
    (continued...)
    -3-
    & Regs. R. 1220-1-2-.16(2). The City’s appeal was based on its contention that there was
    no evidence in the record that TAWC had established a basis for the claimed management
    fees. The City’s prayer for relief was that this Court reverse the TRA’s June 10, 2008 Order
    to the extent it allowed TAWC to increase its rates. In its appellate brief, the City expanded
    its challenge regarding management fee costs to include the allegation that TAWC had not
    introduced any proof at the 2006 Rate Case hearing of its claimed costs regarding
    depreciation, taxes and rate of return on $25,891,327 in claimed additional capital
    investments and claimed regulatory expenses.
    On September 5, 2008, CAPD filed its Notice of Appearance in the 2006 Rate Case
    Appeal in support of the City’s position and TAWC filed its Notice of Appearance in
    opposition to the City. On July 10, 2009, TAWC filed a Motion to Dismiss Appeal for
    Mootness, which was opposed by the City and CAPD. This Court entered an order that it
    would consider the motion to dismiss the appeal following oral arguments.
    On March 14, 2008, TAWC filed a petition and revised tariffs seeking an additional
    increase in its rates, asserting that the rates authorized by TRA in the 2006 Rate Case no
    longer provided TAWC with sufficient revenue to cover all costs incurred in providing water
    service. TAWC requested that this Court take judicial notice of the record from the 2008
    Rate case in this appeal as that case is an issue in the 2006 Rate Case appeal. Because
    TAWC based its motion to dismiss the 2006 Rate Case appeal on its contention that the
    tariffs authorized by the TRA in the 2008 Rate Case made the 2006 Rate Case moot,
    TAWC’s request that this Court take judicial notice of the 2008 Rate case should be granted
    pursuant to Tenn. R. App. P. 13(c). We may take judicial notice of our Court's records and
    of records from “other cases advancing a similar claim of relief and involving the same
    parties or in collateral cases presenting similar or related issues.” Mosely v. Brandon, No.
    M2006-02398-CCA-R3-HC, 
    2007 WL 1774309
    at *4 (Tenn. Crim. App. Jun. 20, 2007).
    Taking judicial notice of records from a separate case involving the same parties or related
    issues is appropriate when the proceedings in that case are “expressly made an issue in the
    case on appeal.” 
    Id. at *4.
    The appeal of the 2008 Rate Case is before the middle section
    of this Court and captioned Tennessee American Water Co. v. Tennessee Regulatory
    Authority, No. M2009-0053-COA-R12-CV.
    In the 2008 Rate Case, the TRA suspended the tariffs that contained the proposed

    (...continued)
    classification, the authority [TRA] shall have power either upon written complaint, or upon its own initiative,
    to hear and determine whether the increase, change or alteration is just and reasonable. The burden of proof
    to show that the increase, change, or alteration is just and reasonable shall be upon the public utility making
    the same. In determining whether such increase, change or alteration is just and reasonable . . . .

    increases, convened a contested case and permitted the CAPD and the City to intervene to
    oppose the proposed rate increase. A hearing on the merits was held in late August 2008, and
    on September 22, 2008, the TRA panel assigned to the 2008 Rate Case authorized a rate
    increase of approximately $1.65 million, which was less than TAWC had requested. TAWC
    then filed revised tariffs reflecting the rate increase approved by TRA on September 29,
    2008. The 2008 Rate Case tariffs provide that the revised tariffs were effective as of
    October 1, 2008 and that they cancelled and replaced the 2006 Rate Case tariffs that are the
    subject of the 2006 Rate Case Appeal under consideration here. The 2008 Rate Case petition
    was filed with TRA more than six months before the 2006 Rate Case Appeal was filed with
    this Court.
    TAWC filed its Petition for Direct Review of the Administrative Proceeding of the
    2008 Rate Case in this Court on March 16, 2009. The City and CAPD filed a Notice of
    Appearance on April 14, 2009.
    The issue we consider is whether the City’s appeal of the 2006 final order no longer
    serves as a means to provide relief and is therefore moot?
    The determination of whether a case is moot is a question of law, and our review is
    purely de novo. Charter Lakeside Behavioral Health Sys. v. Tennessee Health Facilities
    Comm'n, No. M1998-00985-COA-R3-CV, 
    2001 WL 72342
    at *5 (Tenn. Ct. App. Jan. 31,
    2001); Orlando Residence, Ltd. v. Nashville Lodging Co., No. M1999-00943-COA-R3-CV,
    
    1999 WL 1040544
    at *3 (Tenn. Ct. App. Nov. 17, 1999).
    The City and CAPD filed their appeal based on the contention that TRA erred when
    it determined the 2006 Rate Case Tariffs in the 2006 Rate Case. TAWC contends that the
    appeal is moot because the 2006 Rate Case Tariffs were cancelled and replaced by the 2008
    Rate Case Tariffs, thus the 2006 Rate Case Tariffs are no longer in effect and this Court
    cannot afford the appellant any relief.
    It is well established that courts in Tennessee cannot issue advisory opinions. State
    v. Rodgers, 
    235 S.W.3d 92
    , 97 (Tenn. 2007). “However convenient or desirable for either
    party that the questions mooted in the case be authoritatively settled for future guidance, the
    court is not justified in violating fundamental principles of judicial procedure to gratify this
    desire.” 
    Id. (quoting State
    ex rel. Lewis v. State, 
    347 S.W.2d 47
    , 48 (Tenn. 1961). The
    doctrine of mootness ensures that courts do not invest resources on matters that no longer
    represent live controversies and that courts do not issue irrelevant advisory opinions. State
    ex rel. Lewis at 48.
    The mootness doctrine is well established under Tennessee law. Alliance for Native
    American Indian Rights in Tennessee, Inc. v. Nicely, 
    182 S.W.3d 333
    , 339 (Tenn. Ct. App.
    2005)(citing Charter Lakeside Behavioral Health Sys. v. Tennessee Health Facilities
    -5-
    Comm'n, No. M1998-00985-COA-R3-CV, 
    2001 WL 72342
    at *5 (Tenn. Ct. App. Jan. 30,
    2001). A moot case is one that is no longer justiciable because it no longer involves a
    present, ongoing controversy. 
    Id. at 338.
    A case will generally be considered moot if it no
    longer serves as a means to provide relief to the prevailing party. McIntyre v. Traughber,
    
    884 S.W.2d 134
    , 137 (Tenn. App. 1994). A moot case is one that seeks a judgment on a
    matter that, when rendered, cannot have any practical effect upon a then-existing
    controversy; one in which no relief can be granted; or one in which the judgment rendered
    cannot be carried into effect. Boyce v. Williams, 
    389 S.W.2d 272
    , 277 (Tenn. 1965). Cases
    must remain justiciable throughout the course of the litigation, including an appeal. Alliance
    for Native American Indian Rights at 338; State v. Ely, 
    48 S.W.3d 710
    , 716 n. 3 (Tenn.
    2001). When a case is determined to be moot and when it does not fit into one of the
    exceptions to the mootness doctrine, an appellate court will ordinarily vacate the judgment
    below and remand the case to the trial court with directions that it be dismissed. Ford
    Consumer Fin. Co. v. 
    Clay, 984 S.W.2d at 617
    . However, if the case falls into one of the
    recognized exceptions to the mootness doctrine, the appellate court has the discretion to
    reach the merits of the appeal in spite of the fact that the case has become moot. Alliance for
    Native Am. Indian Rights at 339.
    TAWC’s contention that this appeal is moot is valid because the 2006 Rate Case
    Tariffs have been cancelled and replaced by the 2008 Rate Case Tariffs. The facts in the
    record establish that the 2006 Rate Case Tariffs were filed by TAWC on May 17, 2007 and
    they became effective on May 22, 2007. TAWC then filed the 2008 Rate Case Tariffs on
    September 29, 2008 and they became effective on October 1, 2008. By the terms of the 2008
    Rate Case Tariffs, they cancelled and replaced the 2006 Rate Case Tariffs. Accordingly, the
    rates approved by the TRA in the 2006 Final Order are not now in effect, and have not been
    in effect since October 1, 2008. Therefore, if this Court were to determine that TRA did
    commit error in the 2006 Rate Case Final Order, that decision of the Court would have no
    effect on the rates TAWC is permitted to charge its customers now or in the future. See
    McCord v. Nashville Gas Co., No. 87-108-II, 
    1987 WL 28387
    (Tenn. Ct. App. Dec. 23,
    1987).
    Appellants do not dispute that the 2006 Rate Case Tariffs are no longer in effect nor
    do they dispute that those tariffs were cancelled and replaced by the 2008 Rate Case Tariffs.
    Instead, they contend that the 2006 Rate Case Tariffs are still a justiciable issue because, at
    least to some extent, the 2008 Rate Case Tariffs were based upon the 2006 Rate Case Tariffs
    that included the erroneous management fees that form the basis of this appeal. Appellants’
    claim on this issue is not supported by the facts contained in the Final Order in the 2008 Rate
    Case. That Final Order specifically addresses the basis for TRA’s setting of the management
    fees in the 2008 Rate Case and specifically states that the fees were not based on the 2006
    Rate Case. The Order explains that TRA determined the management fees by starting with
    the management fees forecasted for 2005 in a 2004 Rate Case and that figure was adjusted
    for inflation. Based on the plain language of the Final Order in the 2008 Rate Case,
    -6-
    appellants’ argument on this issue is without merit. Accordingly, the appeal is moot as it is
    no longer justiciable as it no longer involves a present, ongoing controversy.
    Tennessee courts have recognized several exceptions to the mootness doctrine and if
    a case falls within one of these exceptions, in our discretion we may reach the merits of the
    appeal in spite of the fact that the case has become moot. The two most commonly occurring
    exceptions to the mootness doctrine are where there are issues of great public interest and
    issues capable of repetition yet evading review. McIntyre at 137. However, even if one of
    the exceptions is applicable, a decision to consider the case on the merits is within the
    discretion of the appellate court. 
    Id. (citing Dockery
    v. Dockery, 
    559 S.W.2d 952
    , 954 (Tenn.
    Ct. App.1977); Gillespie v. City of Memphis, No. W2007-01786-COA-R3-CV, 
    2008 WL 2331027
    at * 5 (Tenn. Ct. App. Jun. 5, 2008).
    The courts invoke the “capable of repetition yet evading review” exception only where
    (1) there is a reasonable expectation that the official act that provoked the litigation will
    occur again, (2) there is a risk that effective judicial remedies cannot be provided in the event
    that the official act reoccurs, and (3) the same complaining party will be prejudiced by the
    official act when it reoccurs. A mere theoretical possibility that an act might reoccur is not
    sufficient to invoke the exception. Rather, there must be a reasonable expectation or a
    demonstrated probability that the same controversy will recur involving the same
    complaining party. 
    Id. Appellants urge
    this Court to apply the “capable of repetition yet evading review”
    exception to the mootness doctrine. First, appellants argue that there is a reasonable
    expectation that the “improper fees and costs comprising a large part of the tariff permitted
    in the 2006 Rate Case will continue to be sought by TAWC in future rate cases.” The City
    supports this position by arguing that TAWC, in the 2008 Rate Case, did not seek to cut the
    improper fees and expenses from its requested adjustment in rates, but rather sought rate
    increases in addition to what it received from the 2006 Rate Case. Assuming arguendo
    appellants argument on the “recurring” prong of the exception were valid, the facts do not
    support a finding that the second prong of this exception is met, that there is a risk that
    effective judicial remedies cannot be provided in the event that the official act reoccurs.
    Quite simply, the fact is that the 2008 Rate Case is currently on appeal before the Middle
    Section of this Court. Thus, even if TAWC had based its request for a rate increase in the
    2008 Rate Case on faulty evidence and TRA had granted TAWC’s petition based on that
    evidence, in other words, the “official act” at issue here had reoccurred, appellant review of
    that act is currently available to appellants should they choose to raise that issue in the
    ongoing appeal of the 2008 Rate Case. Accordingly, appellants’ position as to this exception
    is without merit.
    The Court in Dockery v. Dockery, 
    559 S.W.2d 952
    (Tenn. App. 1977), discussed the
    public interest exception to the mootness doctrine and held that an appellate court may
    -7-
    entertain an appeal for final determination if it involves questions of public interest, even
    though it has become moot so far as the particular action or parties are concerned. 
    Id. at 954.
    There, the Court stated that “[t]he decision as to whether to retain a moot case in order to
    pass on a question of public interest lies in the discretion of the court and generally a court
    will determine a moot question of public importance if it feels that the value of its
    determination as a precedent is sufficient to overcome the rule against considering moot
    questions.” 
    Id. (citing McCanless
    v. Klein, 
    188 S.W.2d 745
    , 747 (Tenn. 1945). The Dockery
    Court noted that this exception to the mootness doctrine is not to be used except in
    extraordinary circumstances “[b]ecause the general rule is to dismiss an appeal which has
    become moot, with the retention of such cases in the public interest being the exception to
    the rule, courts are inclined to refuse dismissal only under exceptional circumstances where
    the public interest clearly appears. Dockery at 954 - 955.
    The Tennessee Supreme Court, in Norma Faye Pyles Lynch Family Purpose LLC v.
    Putnam County, 
    301 S.W.3d 196
    (Tenn. 2009), clarified when the circumstances of a case
    will warrant the invocation of the public interest exception to the mootness doctrine. The
    circumstances of Lynch were that Putnam County and the City of Cookville (County and
    City) filed an eminent domain action to condemn private property owned by Lynch to
    develop an industrial park. The County and City, however, had failed to obtain a certificate
    of public purpose and necessity prior to filing the complaint as required by statute.4 The
    County and City voluntarily dismissed their complaint to allow time to obtain the needed
    certificate after the landowner, Lynch, filed a motion to dismiss based on failure to comply
    with the statute. The landowner then filed a motion for attorney's fees and costs, as well as
    a separate action seeking a partition in kind, an accounting, and damages. In response, the
    County and City opposed the property owner's request for attorney's fees and filed an answer
    in the partition case that included a counterclaim to condemn the property. The County and
    City also moved to set aside the voluntary dismissal of their original condemnation
    complaint. The trial court granted the motion to vacate the dismissal of the condemnation
    complaint, consolidated the condemnation and partition proceedings, and reserved addressing
    the property owner's request for attorney's fees. The landowner applied to the trial court for
    permission to file an interlocutory appeal, which was denied. The landowner then filed an
    application for extraordinary appeal in the Court of Appeals, which was also denied. The
    landowner renewed its application for an extraordinary appeal in the Supreme Court, which
    was granted. Following the Supreme Court’s granting of the application, the County and
    City abandoned their efforts to condemn the property and reconfigured their industrial park
    project to exclude the Lynch property. Following this action, the County and City requested
    that the Supreme Court dismiss the landowner's appeal on the grounds of mootness. The
    landowner opposed the motion for dismissal based on the argument that the interpretation
    of the statute that required a certificate of public purpose and necessity before a
    condemnation suit is filed was “an interest of public character” that “applies to any
    4
    Tenn. Code Ann. § 13-16-207(f).
    -8-
    landowner”. The Supreme Court held that (1) the appeal should not be dismissed for
    mootness based on the public interest exception and (2) that the trial court erred by failing
    to dismiss the County's and City’s condemnation complaint because it had been filed before
    the City and County obtained the certificate of public purpose and necessity required by
    Tenn. Code Ann. § 13-16-207(f). Lynch at 199 - 202.
    Only the first holding of the Supreme Court in Lynch regarding the public interest
    exception to the mootness doctrine is applicable to the matter before this Court here. First,
    the Supreme Court visited the history of the mootness doctrine and the public interest
    exception to that doctrine in Tennessee courts. 
    Id. at 208
    - 210. The Court then summarized
    the general rule of the public interest exception to the mootness doctrine as it stands in
    Tennessee today as follows:
    Our judicial heritage speaks to restraint in addressing issues when the parties do not
    have a continuing, real, live, and substantial interest in the outcome. Tennessee's
    appellate courts should dismiss appeals that have become moot regardless of how
    appealing it may be to do otherwise. However, under “exceptional circumstances
    where the public interest clearly appears,” Dockery v. Dockery, 
    559 S.W.2d 952
    , 955
    (Tenn. Ct. App.1977), the appellate courts may exercise their judgment and discretion
    to address issues of great importance to the public and the administration of justice.
    State v. Rodgers, 235 S.W.3d [92] at 97 [Tenn. 2007].
    Lynch at 210.
    After recognizing that the public interest exception to the mootness doctrine can be
    utilized in extraordinary circumstances at the appellate court’s discretion, the Supreme Court
    offered four threshold considerations that the appellate courts need to address before
    exercising their discretion. Those threshold considerations are: (1) the public interest
    exception should not be invoked in cases affecting only private rights and claims personal
    to the parties; (2) the public interest exception should be invoked only with regard to “issues
    of great importance to the public and the administration of justice”; (3) the public interest
    exception should not be invoked if the issue is unlikely to arise in the future; and (4) the
    public interest exception should not be invoked if the record is inadequate or if the issue has
    not been effectively addressed in the earlier proceedings. 
    Id. at 210
    - 211.
    The Supreme Court then provided that if the threshold considerations do not exclude
    the application of the public policy exception to the mootness doctrine, the appellate court
    has the duty to determine whether the issues in the case are exceptional enough to address
    despite general rule of law that courts will not address an issue that is moot. The Court
    provided the following guidelines that appellant courts may consider in making the
    “exceptional enough” determination: (1) the assistance that a decision on the merits will
    provide to public officials in the exercise of their duties, (2) the likelihood that the issue will
    -9-
    recur under similar conditions regardless of whether the same parties are involved, (3) the
    degree of urgency in resolving the issue, (4) the costs and difficulties in litigating the issue
    again, and (5) whether the issue is one of law, a mixed question of law and fact, or heavily
    fact-dependent. 
    Id. at 211.
    In the case before us, the threshold issues set forth by the Supreme Court are met. By
    its very nature, the case does not involve only private rights and claims. TAWC is a public
    utility that provides water to its customers, the members of the public in and around
    Chattanooga, Tennessee, and TRA is charged with regulating the rates TAWC charges those
    customers. Thus, the actions of both TAWC and TRA affect the interests of the public and
    appellants, the City and the CAPD, intervened in the rate case to represent and protect the
    interests of the public.
    The issue on appeal is whether the evidence presented to the TRA by TAWC proved
    that the proposed rate tariffs in the 2006 Rate Case were just and reasonable. The justness
    and reasonableness of the tariffs approved in the Rate Case is of great importance to the
    public and the administration of justice so the second threshold consideration is met by the
    very nature of the controversy.
    The third threshold consideration is whether the issue is unlikely to arise in the future.
    As TAWC will always have the burden of proving that its proposed tariffs are just and
    reasonable it is possible that TRA or other entities representing the interests of TAWC
    customers may raise the issue of the sufficiency of the evidence presented by TAWC in a
    future rate case. Accordingly, it is unrealistic to conclude that the issue is “unlikely” to arise
    in the future.
    The fourth threshold consideration is also met. The record from the 2006 Rate Case,
    consisting of voluminous transcripts of testimony and exhibits, is adequate for review by this
    Court and the issue of the sufficiency of the evidence was addressed during the Rate Case.
    Having concluded that the four threshold considerations for invoking the public
    interest exception to the mootness doctrine are present, we must consider whether the
    circumstance of this case are so exceptional that we should, in our discretion, employ the
    exception and consider the appeal. The Supreme Court in Lynch offered several suggested
    factors the appellate courts may consider when determining whether a moot case was so
    exceptional that it should be considered. Unlike the threshold considerations, these factors
    were only suggestions or examples of the type of issues an appellate court can consider when
    examining a case for exceptionalism and Lynch does not require, or suggest, that all or any
    of the factors listed must be considered by the appellate court.
    The fifth factor listed in Lynch is whether the issue presented for review is one of law,
    mixed law and fact or fact-dependent. Here, there is no dispute between the parties that
    -10-
    TAWC bore the statutory burden of proving that its proposed rates were just and reasonable
    pursuant to Tenn. Code Ann. § 65-5-103, thus there is no pure question of law at issue. The
    issue raised by appellants is whether the evidence presented by TAWC was sufficient to
    show that the proposed rates were just and reasonable. This issue is clearly one of fact and
    we do not think this Court’s decision in the 2006 Rate Case regarding the sufficiency of the
    testimony and exhibits specific to that case would be of much assistance to another court in
    the future that would be called upon to examine a completely different offer of proof as to
    the just and reasonableness of proposed rates in a different case. Based on the fact intensive
    nature of this appeal, we, in our discretion, decline to apply the public interest exception to
    the mootness doctrine. Moreover, one of the other factors suggested by Lynch comes into
    play here - the degree of urgency in resolving the issue. We cannot appreciate any degree of
    urgency here. First, the rates at issue ceased to be in effect in October 2008. Second, if, in
    another rate case, similar issues arise, the right and ability to appeal will be available to all
    parties. In fact, if these issues are a concern in the 2008 Rate Case, the appellants can raise
    them in the 2008 Appeal which is currently pending. In the exercise of discretion, we will
    not invoke the public interest exception to consider this case which is no longer a justiciable
    controversy.
    In sum, we dismiss this appeal on the grounds of mootness, and remand, with the cost
    of the appeal in our discretion assessed one-half to the City of Chattanooga, Tennessee, and
    one-half to the Tennessee American Water Company.
