    Metropolitan Police Department (MPD), was retired on disability by the District of
    Columbia Police and Firefighters‘ Retirement and Relief Board. She seeks review
    of the Board‘s decision that her injury was not incurred in the performance of duty
    and that she is therefore not entitled to more generous retirement benefits. Lt.
    Nunnally relies principally on Nunnally v. District of Columbia Metropolitan
    Police Department, 
    80 A.3d 1004
    (D.C. 2013), a prior case of Lt. Nunnally‘s in
    which we concluded that, for purposes of the statute governing sick leave for
    public employees, D.C. Code § 1-612.03 (j), Lt. Nunnally‘s injury resulted from
    the performance of duty. 
    Id. at 1010–13.
    We conclude that the question here is controlled not by Nunnally but by our
    decision in Estate of Underwood v. National Credit Union Administration, 
    665 A.2d 621
    (D.C. 1995).      Underwood held that a disabling injury caused by
    workplace sexual harassment could not be an injury ―arising out of . . .
    employment‖ and was thus not compensable under the Workers‘ Compensation
    Act, D.C. Code § 36-301 et seq. (1993 Repl.), the private sector equivalent of the
    Police and Firefighters Retirement and Disability Act—or PFRDA, D.C. Code
    §§ 5-701 to -724—which is D.C.‘s workers‘ compensation plan for firefighters and
    police officers like Lt. 
    Nunnally. 665 A.2d at 630
    . Although Lt. Nunnally makes
    a formidable argument that we should interpret ―performance of duty‖ in the
    PFRDA as we construed the same phrase in the sick leave statute at issue in
    3
    Nunnally, we ultimately conclude that doing so would spark a much more
    substantive inconsistency in our case law by evading the rationale underlying our
    decision in Underwood and creating a legal anomaly in which our case law treats
    workplace sexual harassment differently for police officers and firefighters than for
    other employees in the city. For the reasons explained more fully in this opinion,
    we affirm the Board‘s decision in this case.
    I.
    In 2004, Ronda Nunnally filed an internal MPD complaint alleging that she
    was being sexually harassed by her supervisor. After an investigation, the MPD
    terminated the supervisor.2 Three years later, Lt. Nunnally reported to the Police
    and Fire Clinic that she had undergone several years of workplace stress and abuse
    related to the sexual harassment and to retaliation for reporting it. The clinic
    recommended that Lt. Nunnally be retired as disabled, and the Police and
    Firefighters‘ Retirement and Relief Board accepted this recommendation, finding
    by a preponderance of the evidence that Lt. Nunnally was incapacitated for further
    duty. The Board further concluded that, even viewing Lt. Nunnally‘s allegations
    2
    Lt. Nunnally also filed a civil complaint in Superior Court based on the
    same allegations against her supervisor and the District of Columbia. See Nunnally
    v. Graham, 
    56 A.3d 130
    (D.C. 2012).
    4
    of sexual harassment and retaliation in the light most favorable to her, the Board
    was foreclosed by our decision in Underwood from classifying the injury that gave
    rise to her disability as an injury incurred in the performance of her official duties.
    Lt. Nunnally was therefore entitled to an annuity under D.C. Code § 5-709 (b)3—
    which spells out retirement benefits for those who became disabled due to injury
    received ―other than in the performance of duty‖—rather than the more generous
    annuity provided under § 5-710 (e) for police officers who sustain injuries ―in the
    performance of duty‖ (POD injuries).4
    Lt. Nunnally appealed the Board‘s decision to this court, and we summarily
    remanded the case to the Board for further consideration in light of our holding, in
    Lt. Nunnally‘s separate appeal of the MPD‘s decision to charge her sick leave
    account for a lengthy absence from work, that the psychological injury she
    alleged—the same injury giving rise to her disability in this case—was an ―injury
    . . . resulting from the performance of duty‖ under the sick leave statute, D.C. Code
    3
    All D.C. Code citations are to the 2012 replacement volume unless
    otherwise indicated.
    4
    Specifically, annuities for non-POD injuries under § 5-709 (b) must be at
    least 30% of the officer‘s salary at the time of retirement, while the minimum
    annuity for POD injuries under § 5-710 (e) is 40% of that salary. The Board
    awarded Lt. Nunnally an annuity equal to approximately 35% of her salary at the
    time of her retirement.
    5
    § 1-612.03 (j). See 
    Nunnally, 80 A.3d at 1010
    –13. The Board issued a new final
    order reaffirming its previous conclusion that Lt. Nunnally‘s injury was not
    incurred in the performance of duty.      While taking notice of our holding in
    Nunnally, the Board decided that it was still precluded by Underwood from finding
    injuries caused by sexual harassment to be POD injuries. Lt. Nunnally appealed
    again from this order.
    II.
    The question before us on appeal is whether the Board was correct in
    determining that Underwood compelled the conclusion that Lt. Nunnally‘s injury
    was not sustained in the performance of duty under the provisions of PFRDA that
    set forth the annuities for those who have been retired on disability. See D.C. Code
    §§ 5-709 (b) and -710 (e). As ―[a]n agency‘s interpretation of our case law does
    not trigger any obligation of deference on our part,‖ we review that question de
    novo.5 
    Nunnally, 80 A.3d at 1012
    ; cf. O’Rourke v. District of Columbia Police &
    5
    To the extent our analysis entails a more straightforward interpretation of
    the phrase ―in the performance of duty‖ under D.C. Code §§ 5-709 (b) and -710
    (e), our review is also de novo, as ―we are presumed to have the greater expertise
    when the agency's decision rests on a question of law, and we therefore remain ‗the
    final authority on issues of statutory construction.‘‖ 
    Nunnally, 80 A.3d at 1010
    .
    ―Where we determine that a statutory term is ambiguous, however, we must defer
    to an agency's interpretation of that ambiguity that is reasonable and not plainly
    wrong or inconsistent with the legislature's intent.‖ Id.; see also MorphoTrust

    Firefighters’ Ret. & Relief Bd., 
    46 A.3d 378
    , 383 (D.C. 2012).
    Both of the statutes governing annuity rates for officers retired on disability
    are components of the PFRDA, which ―serves as the worker‘s compensation plan
    for the District‘s police and firefighters.‖ 
    O’Rourke, 46 A.3d at 389
    ; see also
    Vargo v. Barry, 
    667 A.2d 98
    , 101 n.4 (D.C. 1995). Like other such schemes, the
    PFRDA provides swift and certain compensation, but that compensation is limited
    and other remedies, such as common law suits, are precluded. This reflects ―the
    public policy trade-off implicit in workers‘ compensation statutes—substituting
    limited liability without fault for the right to sue in court.‖ 
    Vargo, 667 A.2d at 101
    .
    Lt. Nunnally primarily argues that our decision in Nunnally, which examines
    the same language in a different context, controls this case. In her view, the phrase
    ―performance of duty‖ should have the same meaning in the context of retirement
    for disability as it does for sick leave benefits. As noted above, we held in
    (…continued)
    USA, Inc. v. District of Columbia Contract Appeals Bd., 
    115 A.3d 571
    , 583 (D.C.
    2015) (―In accordance with the Supreme Court's decision in Chevron, . . . before
    we afford some deference to an agency's interpretation of the statute that it
    administers at least two conditions must be met: (1) the statutory language in
    question must be ambiguous, and (2) the agency's interpretation must be
    reasonable.‖).
    7
    Nunnally that Lt. Nunnally‘s psychological injury was incurred in the
    ―performance of duty‖ under the statute governing public employees‘ sick 
    leave. 80 A.3d at 1013
    . Although only that statute, D.C. Code § 1-612.03 (j)—a part of
    the Comprehensive Merit Personnel Act of 1978 (CMPA)6—was at issue in
    Nunnally, we drew parallels to the PFRDA, stating that ―[o]ur understanding of
    ‗performance of duty‘ under D.C. Code § 1–612.03 (j)‖ was ―in line with this
    court‘s broad interpretation of the same phrase when used in the related context‖ of
    the PFRDA.7 
    Id. at 1011.
    Nothwithstanding the analogy this court drew between the PFRDA and the
    sick leave statute in Nunnally, the Board deemed this case to be controlled by
    Underwood.     In Underwood, this court acknowledged precedents holding that
    emotional distress claims not based on sexual harassment might be compensable
    under the Workers‘ Compensation Act (WCA), which defines a compensable
    injury as an ―accidental injury or death arising out of and in the course of
    employment, . . . includ[ing] an injury caused by the willful act of third persons
    6
    D.C. Code §§ 1–601.01 to –636.03.
    7
    In Nunnally we noted a further ―linkage‖ between the sick leave statute
    and the PFRDA: D.C. Code § 5-708.01, a provision the D.C. Council added to the
    PFRDA in 2004 that governs claims processing for alleged POD injuries under
    § 1–612.03 
    (j). 80 A.3d at 1011
    n.14.

    directed against an employee because of his [or her] 
    employment.‖ 665 A.2d at 631
    –32 & 633 (quoting D.C. Code § 32-1501 (12)). Special considerations led the
    court to reach a different result, however, ―when emotional distress allegedly
    attributable to sexual harassment (in contrast with some other cause) results in
    disabling injuries[.]‖ 
    Id. at 632–33.
    Based on what it called a ―significant policy
    consideration,‖ 
    id. at 637,
    the court in Underwood concluded that workplace
    sexual harassment was ―unrelated to any work task‖ and could not be an injury
    ―arising out of . . . employment.‖8 
    Id. at 634,
    637. That policy consideration was
    the likelihood that declaring injuries from workplace sexual harassment to be
    compensable in workers‘ compensation ―would frustrate implementation of the
    Human Rights Act,‖ 
    id. at 637,
    the local human rights law that prohibits sex
    discrimination, including sexual harassment, and provides both a private cause of
    8
    Indeed, the court noted, sexual harassment was forbidden by the District of
    Columbia Human Rights Act, D.C. Code §§ 2-1401 to -1403. And while
    compensable injuries to police officers may often arise out of activity prohibited by
    a statute, see, e.g., 
    O’Rourke, 46 A.3d at 381
    (officer injured while chasing
    suspected carjacker), such injuries are contemplated by law as potential hazards of
    employment as a police officer. By contrast, the Human Rights Act does not treat
    sex discrimination—including sexual harassment—as an odds-on occurrence that
    is incidental to employment. Cf. Bennett v. Furr’s Cafeterias, Inc., 
    549 F. Supp. 887
    , 890 (D. Colo. 1982) (denying defendant‘s request for summary judgment on
    plaintiff‘s sexual-harassment-related claims for assault and battery and outrageous
    conduct, stating that ―[i]ndeed, it would appear to lie outside the bounds of reason
    to propose that the sort of sexual assault and harassment heretofore described and
    the emotional trauma alleged to have been caused thereby result from risks
    inherent to the position of a ‗management trainee.‘‖).

    action and an administrative remedy through the Office of Human Rights. See
    D.C. Code § 2-1403.16 (private cause of action) and § 2-1403.04 (administrative
    remedy).
    As a workers‘ compensation scheme, the WCA provides an exclusive
    remedy against the employer for injuries within its scope, preempting causes of
    action based on the same alleged injuries. D.C. Code § 32-1504. The difficulty in
    deeming sexual harassment claims to be covered under the WCA was not,
    however, that the workers‘ compensation statute would preempt the Human Rights
    Act‘s remedies, and no one in Underwood argued 
    that.9 665 A.2d at 631
    . Instead,
    the concern of this court at the time, and of many courts considering appeals from
    the dismissal of sexual harassment suits, was the ability of sexual harassment
    9
    The Board in its decision misunderstood Underwood to have expressed
    concern that a WCA remedy would preempt Human Rights Act remedies, and the
    parties in their briefs have either shared that misunderstanding or failed to
    challenge it. In fact, Underwood emphasized as ―important background‖ its
    understanding—shared by the parties in that case—that the question of WCA
    preemption would not have arisen had the case contained a Human Rights Act
    
    claim. 665 A.2d at 631
    . It was because the ―case no longer contain[ed] a statutory
    sexual harassment claim‖ after the jury rejected that claim that the employer
    contended that ―the WCA—the only statute now in the picture—preempted a
    lawsuit for a common law tort,‖ which was the sole claim remaining in the
    plaintiff‘s case. Id.; cf. Johnson v. District of Columbia, 
    528 F.3d 969
    , 978 (D.C.
    Cir. 2008) (affirming dismissal of common law claims on ground that PFRDA was
    officer‘s exclusive remedy against the District but remanding to allow statutory
    claim to go to trial).

    victims to obtain full and appropriate relief, particularly under tort theories—
    assault, infliction of emotional distress, defamation, battery, invasion of privacy,
    and the tort of ―outrage,‖ among others—that typically accompany a plaintiff‘s
    statutory sexual harassment claims.10
    Such tort claims, ―when premised on alleged disability from sexual
    harassment,‖ would be preempted if a WCA remedy were available, which would
    10
    See, e.g., Anderson v. Save-A-Lot, Ltd., 
    989 S.W.2d 277
    , 290 (Tenn.
    1999) (noting that a ruling that employee plaintiffs can recover worker‘s
    compensation for injuries stemming from sexual harassment could ―thwart the
    intent of the framers of the [Tennessee Human Rights Act] to provide sexual
    harassment victims with a full recovery‖). The Tennessee Supreme Court, which
    was considering an employee‘s appeal from the denial of workers‘ compensation
    for emotional injuries caused by sexual harassment by a manager, acknowledged
    that most of the published decisions on this subject involve circumstances in which
    ―the employee plaintiffs were seeking to recover under tort theories or pursuant to
    civil rights legislation.‖ 
    Id. at 282.
    The court in Anderson, in a decision expressly
    intended to protect sexual harassment victims‘ ability to recover for their injuries,
    ruled against the plaintiff, who was seeking worker‘s compensation, not the right
    to sue for sexual harassment. The court even ended its opinion with a quotation
    denigrating the value of the relief the employee was seeking: ―Except for the
    convenience of employers and the flimsy benefit the victims of sexual harassment
    might achieve by quicker, but much smaller awards, it is difficult to conjure a
    reason for workers‘ compensation courts handling sexual-harassment cases.‖
    
    Anderson, 989 S.W.2d at 290
    (quoting Darryll M. Halcomb Lewis, Sexual
    Harassment Under Workers’ Compensation Law, 44 Labor L.J. 297, 306 (1993)).
    Both Anderson and Ms. Nunnally‘s present appeal serve as a reminder that
    employees seeking remedies for workplace sexual harassment are not a
    homogeneous group, that their claims arise in countless ways, and that
    Underwood‘s holding that injuries caused by workplace sexual harassment do not
    arise out of employment will effectively prevent recovery for some victims whose
    claims or circumstances may not be conducive to a lawsuit.
    11
    ―frustrate Human Rights Act policy‖ in several ways.11 
    Id. at 637.
    Plaintiffs
    would be forced to split their claims between two forums, rather than attaching
    their tort claims to their Human Rights Act claims in court; to ―settle for a remedy
    out of keeping with the kind of injury involved,‖ given the ―severe cap on
    allowable recovery‖ in workers‘ compensation; and to face the specter of issue
    preclusion, which could doom a civil claim based on earlier findings by a workers‘
    compensation tribunal. 
    Id. at 637–38.
    We also noted that judicial economy would
    be disserved by encouraging claim-splitting and that a workers‘ compensation
    agency lacks expertise in adjudicating claims of emotional distress based on sexual
    harassment. 
    Id. at 637.
    These considerations contributed to Underwood‘s holding
    that ―disabling injuries from emotional distress caused by sexual harassment . . .
    ‗clearly are not compensable under the [WCA].‘‖ 
    Id. at 633
    (quoting Harrington
    v. Moss, 
    407 A.2d 658
    , 661 (D.C. 1979)). The Underwood court‘s rationale
    echoes that which many courts in other jurisdictions have relied upon in likewise
    holding that those states‘ workers‘ compensation laws do not bar tort suits related
    11
    Underwood urged caution regarding the scope of sexual harassment
    claims excluded from workers‘ compensation. 
    Id. at 633
    n.18. Here, we are not
    confronted with a case in which sexual harassment and related retaliation account
    for only one portion of an injury due to emotional distress; ―for example, a pattern
    of actionable emotional abuse by a supervisor over a period of months or years
    with no perceptible sexual content, followed by the supervisor‘s effort over
    succeeding months to reorient the relationship through sexual overtures and
    threats.‖ 
    Id. 12 to
    sexual harassment. See, e.g., Hart v. National Mortg. & Land Co., 235 Cal.
    Rptr. 68, 75 (Cal. Ct. App. 1987) (stating that ―when employers step out of their
    roles as such and commit acts which do not fall within the reasonably anticipated
    conditions of work, they may not then hide behind the shield of workers‘
    compensation‖); Dunn v Warhol, 
    778 F. Supp. 242
    , 244 (E.D. Pa. 1991) (rejecting
    employer‘s argument that Pennsylvania‘s workers‘ compensation act provided
    exclusive remedy for sexual harassment claim, stating that ―it does not follow‖ that
    ―sexual harassment by a supervisor who also happens to be the victim‘s employer
    is related to the scope of her employment‖); Harrison v. Edison Bros. Apparel
    Stores, Inc., 724 F. Supp 1185, 1191 (M.D.N.C. 1989) (rejecting employer‘s
    argument that the injuries resulting from sexual harassment ―are a natural risk of
    employment‖ and that North Carolina‘s workers‘ compensation act therefore
    provided exclusive remedy for plaintiff‘s negligent-retention claim), remanded on
    other grounds, 
    924 F.2d 530
    (4th Cir. 1991); cf. Lucero-Nelson v. Washington

    emotional distress claims that accompanied the employee‘s Title VII and Human
    Rights Act sexual harassment claims).12

    A deep split has emerged in state courts—and in federal courts applying
    (continued…)
    13
    Like the WCA, the PFRDA provides a comprehensive and therefore
    exclusive compensation scheme. See Lewis v. District of Columbia, 
    499 A.2d 911
    ,
    913 (D.C. 1985); Johnson v. District of Columbia, 
    528 F.3d 969
    , 978 (D.C. Cir.
    2008).13   And while the WCA‘s language regarding its coverage of injuries

    state law—regarding the extent to which the exclusivity provisions of worker‘s
    compensation laws preclude plaintiffs‘ lawsuits for sexual harassment and related
    common law torts. Many courts have concluded that such claims do arise out of
    employment and that their workers‘ compensation scheme is the exclusive remedy.
    See, e.g., Guess v. Bethlehem Steel Corp., 
    913 F.2d 463
    , 465–66 (7th Cir. 1990)
    (affirming dismissal of plaintiff‘s sexual-harassment-related tort claims based on
    Indiana precedent establishing that such claims are ―within the exclusive
    jurisdiction of the workmen‘s compensation law‖); Doe v. Purity Supreme, Inc.,
    
    664 N.E.2d 815
    , 819 (Mass. 1996) (holding that the state‘s workers‘ compensation
    act barred the plaintiff‘s common law claims because ―the assistant store manager
    is alleged to have raped an employee during work hours on the employer‘s
    premises‖ and noting that ―the Legislature has provided employees with a separate
    remedy for sexual harassment‖); Campbell v. Jackson Bus. Forms Co., 841 F.
    Supp. 772, 774 (S.D. Miss. 1994) (ruling that the Mississippi workers‘
    compensation law barred the plaintiff‘s common law negligent-supervision-of-
    employees claim ―[b]ecause Campbell alleges that her claim arose out of the
    employer-employee relationship‖ between her and the employer ―and because the
    tort claim is clearly grounded in negligence‖).
    13
    Unlike the WCA and the CMPA, see D.C. Code § 32-1504 (b), § 1-623.16
    (c), the PFRDA contains no exclusivity provision stating that it is an officer‘s sole
    remedy for injuries that fall within the Act‘s parameters. In Lewis, we nevertheless
    adopted the ―principle . . . of long-standing application‖ that a comprehensive
    system of compensation set up to provide a remedy for employment-related
    injuries ―is presumed to be the exclusive means of redress against the government
    for all persons eligible for the system‘s benefits‖ even in the absence of statutory
    (continued…)
    14
    ―arising out of and in the course of employment‖ differs from the PFRDA‘s
    coverage of injuries incurred ―in the performance of duty,‖ the CMPA‘s
    performance-of-duty language is ―conceptually close‖ to the WCA standard and
    has been construed in some agency decisions as ―requiring that the ‗injury arise out
    of and in the course of employment,‘ the same standard used under the WCA.‖

    947 A.2d 1191

    640 A.2d 656
    , 664 (D.C. 1993)
    (finding ―no basis to conclude that CMPA‘s remedial system preempts Kidd‘s tort
    claim of intentional infliction of emotional distress based on acts of sexual
    harassment and subsequent retaliation‖);

    (―We
    perceive no distinction between public and private employment that could warrant
    a different result from King under the WCA, unless there are differences between
    CMPA and the WCA that would so require[.]‖). Lt. Nunnally‘s claim that she
    should receive a higher minimum annuity under the PFRDA (as opposed to a less
    generous annuity with the option to file a tort claim) is admittedly contextually
    distinct from the typical workers‘ compensation claim seeking payment, for
    example, of medical expenses stemming from an on-the-job injury. But we cannot

    disability and non-POD retirement disability, among other provisions, as grounds
    for concluding the PFRDA ―is comprehensive, and thus exclusive‖); Ray v.
    District of Columbia, 
    535 A.2d 868
    , 870–71 (D.C. 1987) (rejecting a firefighter‘s
    contention that a civil action was available for claims arising from injuries that
    were not on-the-job injuries but were suffered while he was retired on disability, as
    such injuries were ―within [the] range of consequences to which [PRFDA] affords
    the exclusive remedy‖).
    Lt. Nunnally‘s Nunnally-based argument is not without force. It is awkward
    to classify a single injury as an injury ―resulting from the performance of duty‖
    under D.C. Code § 1-612.03 (j) but as an ―injury received . . . other than in the
    performance of duty‖ under D.C. Code § 5-709 (b). The natural presumption that
    the same term should be interpreted consistently in different statutes, however, is
    far from irrebuttable. Even within the same statute a term ―may take on distinct
    characters from association with distinct statutory objects calling for different
    implementation strategies.‖ Envtl. Def. v. Duke Energy Corp., 
    549 U.S. 561
    , 573–
    74 (2007); see also Atl. Cleaners & Dyers, Inc. v. United States, 
    286 U.S. 427
    , 433
    (1932). The presumption of identical meaning may be even weaker where, as here,
    the two statutes were enacted at different times by different legislatures. The
    16
    CMPA, including the sick leave statute, was enacted by the District of Columbia
    Council in 1979, while the relevant PFRDA provisions were enacted by Congress
    in 1916 and amended by Congress in 1957 and 1979.14
    In the end, interpreting ―performance of duty‖ in the PFRDA in line with
    what we have determined that phrase means in the sick leave statute would bring
    about a more significant peculiarity:      workplace sexual harassment would be
    treated differently for police and firefighters than for everyone else in the District.
    For private sector workers, injuries from sexual harassment are not compensable in
    workers‘ compensation and the courts remain open to common law claims,
    
    Underwood, 665 A.2d at 638
    , and a similar rule applies for most public sector
    workers, 
    King, 640 A.2d at 664
    . Only police officers and firefighters alleging
    sexual harassment would be relegated to the exclusive and limited remedies of
    workers‘ compensation.      In the absence of any legislative intent or apparent
    rationale supporting this distinction, our decision in Underwood precludes us from
    14
    As originally enacted, the PFRDA spoke of injuries incurred ―in the line
    of duty.‖ Act of Sept. 1, 1916, ch. 433, § 12, 39 Stat. 678, 718; see also Dougherty
    v. United States ex rel. Roberts, 
    30 F.2d 471
    , 471–72 (D.C. Cir. 1929). The 1957
    amendments introduced the ―performance of duty‖ language to this section. Police
    and Firemen‘s Retirement and Disability Act Amendments of 1957, Pub. L. No.
    85-157, § 3, 71 Stat. 391, 394–95 (1957).
    17
    causing this arbitrary and anomalous result.15 We therefore hold that injuries from
    sexual harassment are not injuries incurred ―in the performance of duty‖ under
    D.C. Code §§ 5-709 (b) and -710 (e).
    III.
    For the reasons in this opinion, we affirm the Board‘s conclusion that Lt.
    Nunnally‘s injury was ―received . . . other than in the performance of duty.‖ D.C.
    Code § 5-709 (b).
    So ordered.
    15
    Lt. Nunnally also relies on Pierce v. District of Columbia Police and
    Firefighters’ Retirement & Relief Board, 
    882 A.2d 199
    (D.C. 2005). The claimant
    in Pierce argued that the disabling mental illness for which she was retired from
    the MPD was due to a POD injury—namely workplace harassment and
    discrimination. 
    Id. at 203–04.
    Most of the harassment she alleged was nonsexual,
    but she did assert that ―she was inappropriately touched by a male supervisor,
    while another male supervisor would ask her to kiss him.‖ 
    Id. at 209.
    We noted
    that if true this allegation could be ―a basis for recovery,‖ but concluded that the
    Board had a reasoned basis for believing these acts had never occurred. 
    Id. We do
    not read this single sentence in Pierce—which was unnecessary to the result, did
    not specify the means of whatever recovery it contemplated, and did not cite the
    contrary precedent of Underwood or attempt to reconcile its conclusion—as having
    settled the question whether sexual harassment was compensable in workers‘
    compensation. See Murphy v. McCloud, 
    650 A.2d 202
    , 205 (D.C. 1994) (―The
    rule of stare decisis is never properly invoked unless in the decision put forward as
    precedent the judicial mind has been applied to and passed upon the precise
    question.‖ (quoting Fletcher v. Scott, 
    277 N.W. 270
    , 272 (Minn. 1938))).
