The question in this case is one of statutory interpretation: whether a police officer who has applied or been recommended for a disability retirement pension under the District of Columbia Police and Firefighters’ Retirement and Disability Act (the “Retirement and Disability Act”),1 loses his eligibility for such a pension if, for any reason, he is terminated from the police force before the Police and Firefighters’ Retirement and Relief Board (the “Retirement and Relief Board” or the “Board”) finally adjudicates his entitlement to the pension. Petitioner O’Rourke was an officer of the Metropolitan Police Department when he was injured while on active duty. As a result, he was recommended for a disability retirement annuity. While the recommendation was still in the administrative pipeline, the Department commenced a separate and unrelated disciplinary proceeding against O’Rourke. This disciplinary proceeding culminated in a decision to terminate his employment. Upon learning of O’Rourke’s termination, the Retirement and Relief Board ruled that he was no longer eligible to receive a disability pension because he was no longer a “member” of the Metropolitan Police. In his petition for review of that ruling, O’Rourke contends that his termination did not sever his right to be considered for a disability pension.
We agree with O’Rourke. We hold that his active membership in the Metropolitan Police Department at the time his retirement on disability was recommended to the Board was sufficient to preserve his *381right, upon a determination that he was otherwise eligible, to a disability annuity. As we interpret the Retirement and Disability Act, O’Rourke’s subsequent disciplinary termination did not render him ineligible for that annuity. In reaching that conclusion, we depart from our usual deference to an administrative body’s construction of the legislation it administers, because we conclude that the Board’s interpretation is incompatible with the broader statutory framework and the primary purpose of the Act. We therefore reverse and remand for further proceedings before the Board.
I.
After serving for twenty-six years with the New York City Police Department and for brief stints thereafter with the U.S. Mint Police and the U.S. Federal Protective Service, Joseph O’Rourke joined the District of Columbia Metropolitan Police Department in 2001. He was then fifty-two years old. O’Rourke was assigned to the Third District, where he served for the next several years as a patrol officer. In July 2007, O’Rourke sustained injuries to his head, hands, and left elbow when he fell onto a concrete walkway while chasing a suspected carjacker. O’Rourke was placed on medical leave; the Director of the Department’s Medical Services Division (the “Director”) classified his injuries as having been incurred in the performance of duty. A year later, after O’Rourke had undergone various unsuccessful medical treatments, the Police and Fire Clinic, with the Director’s approval, recommended to the Retirement and Relief Board that O’Rourke be retired on disability because his “ongoing pain and weakness of his left hand preclude him from carrying out the full duties of a police officer.” [App. 28] Accordingly, the Board held a hearing in February 2009 to determine O’Rourke’s eligibility for a disability retirement pension.
A decision by the Board was not soon forthcoming. Meanwhile, in September 2009, the Police Department served O’Rourke with notice of a proposed disciplinary action, namely termination of his employment. O’Rourke was charged with having secured his appointment to the force in 2001 by falsely stating in his Personal History Booklet that he never had been examined by a physician for “a disease or incorrect functioning of any part of [his] body, when [he] in fact underwent a series of tests to determine [his] qualification for disability” on account of a heart condition after he retired from the New York City police force. [S.A. 1A] In March 2010, following a hearing before a Police Department disciplinary panel, O’Rourke was found guilty of this charge, and the Police Department terminated his employment effective May 7, 2010.2 The notice of termination informed O’Rourke of his right to receive a deferred annuity under the Police and Firefighters’ Retirement Plan.3 It said nothing, however, about his eligibility for the disability retirement annuity for which he had been recommended. That recommendation still was pending before the Retirement and Relief Board.
The Board took note of the disciplinary proceedings. On May 27, 2010, it convened in executive session to consider the impact of O’Rourke’s dismissal. Thereaf*382ter, in a decision dated August 26, 2010, the Board concluded that because O’Rourke was no longer a “member” of the Metropolitan Police Department, he was no longer eligible for a disability retirement pension.
II.
The Retirement and Disability Act provides that police and firefighters may be eligible for two types of disability retirement annuities: one for disabling injuries or diseases incurred or aggravated in the performance of official duty (“POD”), as set forth in D.C.Code § 5-710, and the other for disabilities due to injury or disease not received or contracted in the performance of duty, as set forth in § 5-709. The main difference between the two annuities is the rate of compensation.4 (An additional difference is that a police officer or firefighter must have completed at least five years of service to retire on non-POD disability, while there is no length-of-service condition for POD-disability retirement.5)
As the Retirement and Relief Board said in its decision, §§ 5-710 and 5-709 provide for the retirement of a disabled “member.” The term “member” is defined, somewhat circularly, to include “any officer or member of the Metropolitan Police force.”6 The sections say that a “member shall be retired” on disability only with the approval of the Mayor.7 The Board, acting in its capacity as the Mayor’s agent,8 construed this statutory requirement to mean that an officer cannot receive a disability annuity unless he is still a “member” of the Police force when the Board has completed its evaluation and is ready to render a decision — regardless of how long that administrative process may take. Therefore, the Board reasoned, an officer becomes ineligible for a disability annuity if he is discharged from the Police force while the Board is still considering his case — even if he would have been entitled to the annuity *383had the Board acted more promptly. The Board noted that this conclusion was consistent with an unpublished 1997 opinion of this Court.9
III.
Our review of the Board’s construction of the Retirement and Disability Act is de novo, for this court is “the final authority on issues of statutory construction” 10 and “the ultimate interpreter of the statutory provisions from which the Board, as a creature of the legislature, derives its powers.”11 Ordinarily, we have good reason to respect an administrative agency or board’s informed interpretation of the statute it administers, and we will defer to it “as long as that interpretation is reasonable and not plainly wrong or inconsistent with [the statute’s] legislative purpose.”12 But those caveats are important. We owe no deference where the administrative body has not considered the policy underlying the statute and has reached a result that is contrary to the purpose of the legislation and not reasonable.13 Because we perceive that to be the basic flaw in the Board’s interpretation in this case, we do not defer to it and we must reject it.
“The first step in construing a statute is to read the language of the statute and construe its words according to their ordinary sense and plain meaning.”14 If the statute is “clear and unambiguous, we must give effect to its plain meaning.” 15 But our focus cannot be too narrow, for “[t]he plainness or ambiguity of statutory language is determined [not only] by reference to the language itself,” but also by considering “the specific context in which that language is used, and the broader context of the statute as a whole.”16 “It is a fundamental canon of statutory construction that the words of a statute must be read in their context and with a view to their place in the overall statutory scheme. A court must therefore interpret the statute as a symmetrical and coherent regulatory scheme, and fit, if possible, all parts into an harmonious whole.”17 In short, we must construe *384§§ 5-709 and 5-710 “not in isolation, but together with other related provisions,” and derive their meaning “not from the reading of a single sentence or section, but from consideration of [the] entire enactment against the backdrop of its policies and objectives.”18
The Retirement and Relief Board reads the word “member” in §§ 5-709 and 5-710 restrictively, to include only someone who is a “current member” — as opposed to a “current or former member” — when the administrative decision finally is made whether to retire him on disability. If our analysis not only started, but also ended, with the words of the two statutory sections in question, this would be a possible reading. It is not an obvious or necessary reading, however. “[T]here is no temporal qualifier [of the word “member”] in the statute[s] such as would make plain” that only current members may be retired on disability.19 The definition of “member” in § 5-701(1) likewise contains no temporal qualifier. Moreover, both § 5-709 and § 5-710 include a provision that plausibly supports the broader reading that a disabled officer need only be an active “member” when the recommendation or application for retirement on disability is submitted to the Board in order to be eligible to receive a disability pension. Section 5-710(e-l) states that
Whenever the Board of Police and Fire Surgeons receives a recommendation from the Director for a disability retirement of a Metropolitan Police Department or Fire and Emergency Medical Services Department member pursuant to Chapter 6A of this title, the Board of Police and Fire Surgeons shall make a disability assessment and, if the member is unable to perform the full range of duties, shall retire the member as disabled regardless of whether the member is performing useful and efficient services that are less than the full range of duties. The member shall be retired on an annuity determined in accordance with subsection (e)(2) of this section [explaining how the amount of the annuity is calculated for a member retired for disability incurred or aggravated in the performance of duty]. [Emphasis added.]
Section 5-709(c) is materially identical. In conjunction with the mandatory character of the language in these provisions, we cannot ignore the fact that “the member” to whom the provisions repeatedly refer is simply the individual who is the subject of the Director’s disability retirement recommendation. Thus, even if considered in isolation, the two statutes may be read as requiring the Board to award a disability pension to a disabled former member who was a current member when the proceedings before the Board commenced. On the face of things, the Board’s contrary interpretation is not the only reasonable one, and the statutes are ambiguous.
Does the Board’s choice deserve our deference? The Board did not provide a reasoned analysis explaining its construction of the disability retirement statutes in light of the broader statutory framework or the primary purpose of the Retirement and Disability Act. For his part, O’Rourke, seeking to cut the Gordian Knot without *385such in-depth analysis, urges us to be guided by the opinion of the Court of Appeals of the District of Columbia20 a century ago in Rudolph v. Mosheuvel. 21 Superficially, the legal question before the court in Rudolph was equivalent to the one before us now — whether a fireman injured in the line of duty had a right to be considered for a disability pension even though he was fired before the examining board determined his eligibility for that pension. The fireman’s dismissal could not, by itself, vitiate his entitlement to the pension, the court held, because “the right of the relator to retirement on a pension under the terms of the law were [sic] fixed at the time he received his injuries, provided, of course, that they permanently disabled him from duty and were not the result of his own indiscretion. The commissioners could not, by dismissing him on charges made thereafter, deprive him of the bounty provided by law, which they had no power to suspend.”22 However, because we operate under a very different statutory scheme today, Rudolph is distinguishable, and it is not binding on us here.23 At most, Rudolph is suggestive, not dispositive.
An interpretive issue similar to the one we now confront was presented to the Supreme Court in Robinson v. Shell Oil Company, 24 and we find the Court’s approach instructive. Section 704(a) of Title VII of the Civil Rights Act of 1964 makes it unlawful “for an employer to discriminate against any of his employees or applicants for employment” who have invoked Title VU’s protections or assisted others in doing so.25 Does this statute enable a terminated employee to sue his former employer for post-employment retaliation? “At first blush,” the Court said, “the term ‘employees’ in § 704(a) would seem to refer [only] to those having an existing employment relationship with the employer in question.”26 In context, however, the Court found it ambiguous whether “employees” excludes former employees. Because the opposite reading was “more consistent with the broader context of Title VTI and the primary purpose of § 704(a),” the Court resolved the ambiguity by holding that former employees are included within § 704(a)’s coverage.27
A similar inquiry into statutory context and purpose in the present case persuades us that the Board’s reading of §§ 5-709 and 5-710 is unreasonable. Admittedly, a review of the usage of the term “member” in the immediate statutory environment surrounding these two sections is inconclusive. Sometimes the term “member” is used in other provisions of the Retirement and Disability Act to include or mean former members. For example, the Act refers to officers who have been separated *386from the service simply as “members” when it provides how they may reestablish lost annuity rights.28 The section of the Act dealing with cost-of-living adjustments of annuities similarly refers to retired officers as “members.”29 But the Act is not entirely consistent in this regard; in other places it distinguishes “former members” from “members.”30 The inconsistent usage leaves us guessing; it simply underscores the ambiguity of the term “member” and the inadequacy of the Board’s analysis of its meaning in §§ 5-709 and 5-710. “Once it is established that the term [member] includes former [members] in some sections, but not in others, the term standing alone is necessarily ambiguous and each section must be analyzed to determine whether the context gives the term a further meaning that would resolve the issue in dispute.”31
Considering how the disability retirement provisions fit into the overall statutory framework, we find that the Board’s interpretation leads to perverse or incongruous consequences. Consider, first, that the Board’s holding is not limited to situations in which the member’s employment was terminated, as in O’Rourke’s case, for misconduct. A member may retire voluntarily by giving advance notice,32 or he may be retired for non-disciplinary reasons; the Board’s rationale applies equally to all such situations. With that in mind, it is easy to see why the Board’s ruling is problematic. To give just one example, D.C.Code § 5-712(b) provides that the Mayor may retire any member of the Metropolitan Police force or the Fire Department who has reached the age of sixty. Suppose an officer is injured in the line of duty and recommended for a disability annuity just as he is on the verge of retirement at age sixty pursuant to § 5-712(b)— the very day before his retirement is set to commence, perhaps. Under the Board’s interpretation of the disability retirement provisions, the happenstance of his immediate, mandated retirement at sixty would deprive the officer of a disability annuity simply because the Board could not finish evaluating and processing the disability re*387tirement recommendation quickly enough. We can conceive of no justification for such an arbitrary and harsh result.
Moreover, even if it could be limited to disciplinary terminations, the Board’s ruling poses a problem, for it is in tension with provisions of D.C. Law 13-160, the Omnibus Police Reform Amendment Act of 2000, that were enacted specifically to govern the retirement of police officers who are under disciplinary investigation.33 Although these provisions were legislated by the Council years after the enactment of §§ 5-709 and 5-710, they have a significant bearing on our construction of those statutes. As the Supreme Court has explained, other acts often may elucidate or affect a statute’s meaning, “particularly where [the legislature] has spoken subsequently and more specifically to the topic at hand.”34 Courts frequently
interpret a statutory text in the light of surrounding texts that happen to have been subsequently enacted. This classic judicial task of reconciling many laws enacted over time, and getting them to “make sense” in combination, necessarily assumes that the implications of a statute may be altered by the implications of a later statute.[35]
In D.C. Law 13-160, the Council provided for the completion of disciplinary investigations of members of the Metropolitan Police Department who retire or resign while under investigation for serious misconduct.36 Such a member, who previously could avoid being disciplined by voluntarily retiring or resigning, now is deemed to be in “conditional retirement” until the investigation is concluded.37 While he remains in that status, he “shall not be paid a pension or receive other accrued benefits of any kind, including salary.”38 The withholding of benefits is only temporary, however. If it is found that the conditionally retired member should be subjected to discipline for serious misconduct, that does not result in the loss of any retirement benefits the member is entitled to receive. Rather, the statute provides for the assessment of specified monetary penalties in lieu of the discipline that would have been imposed had the member not retired or resigned.39 If the conditionally retired member would have been terminated, the monetary penalty may range from $1000 *388to $5000.40 The monetary penalty “shall be treated as a debt owed to the District of Columbia government and shall be deducted from the member’s pension, retirement pay, or any other accrued benefits.”41
Accordingly, if the Retirement and Relief Board had found O’Rourke eligible for retirement on disability before the Police Department concluded its disciplinary proceedings, he would have been entitled under the conditional retirement statute to receive a disability annuity (subject to the Department postponing the effective start of his retirement, finishing its investigation, and assessing the penalty imposed). It is hard to see why it should make a material difference that the disciplinary investigation happened to be concluded first. When retirement and disciplinary inquiries are proceeding contemporaneously on parallel tracks, it is illogical for a member’s entitlement to a disability annuity to turn on irrelevant fortuities like the duration of the administrative or adjudicative processes in his particular matter — a factor that may vary greatly from case to case and that usually is outside the member’s control.42
Still less would it be acceptable to construe the Retirement and Disability Act as granting the Board the discretion to manipulate outcomes by deliberately delaying its decisions on disability retirement applications when it learns that the applicant may be terminated.43 The Board does not claim to have such discretion, and it denies having deliberately delayed ruling on O’Rourke’s entitlement to a disability annuity in order to await the outcome of his disciplinary proceeding and thereby prevent him from taking conditional retirement. Nonetheless, at oral argument the Board’s counsel suggested that such action would have been justified because the Board has a responsibility to protect the “integrity of the system” from an applicant seeking to capitalize on his fraud in obtaining his appointment to the Police force. This argument finds no support in the Retirement and Disability Act or our previous decisions. To the contrary, as this court has said, “it is not the province of the Retirement [and Relief] Board to exercise disciplinary functions.”44 Board proceedings are separate from and independent of departmental disciplinary proceedings and should not be entangled with them; indeed, we perceive no reason why the Board should be apprised of disciplinary proceedings that are unrelated to the factual issues before the Board. A deliberate decision by the Board to postpone its determination of a member’s entitlement to a disability annuity pending the outcome of a disciplinary proceeding would thwart the conditional retirement scheme adopted by the Council, disregard the Board’s statutory obligations to make a disability assessment (as set forth in §§ 5-709(c) and 5-710(e-l)), and arbitrarily deny or jeopardize the member’s legal rights.
*389We therefore are compelled to conclude that the Board’s restrictive interpretation of §§ 5-709 and 5-710 is at odds with the conditional retirement statute and the statutory framework as a whole. It would be “far more consistent” to include former members within the scope of the “members” who may be retired on disability under §§ 5-709 and 5-710.45
The Board’s interpretation also conflicts with the primary purpose of the Retirement and Disability Act. That Act serves as the worker’s compensation plan for the District’s police and firefighters.46 “As in the case of workers’ compensation, those who apply for relief under the [Retirement and] Disability Act are assured of receiving ‘adequate and certain compensation expeditiously and without regard to fault.’ ”47 “Such remedial legislation is typically given liberal construction by the courts to effectuate its humanitarian purposes, with exemptions and exceptions narrowly construed and doubts resolved in favor of the employee.”48
As a rule, and as we have held in construing the District of Columbia Workers’ Compensation Act, the termination of an employee for reasons unrelated to his injury or claim does not disentitle the employee from receiving disability benefits. There is no reason why it should. In Upchurch v. District of Columbia Department of Employment Services, 49 where the employee initially was denied benefits after having been fired following his workplace injury, we stated:
This court can find no authority, from any jurisdiction or legal treatise, which would support the proposition that termination severs the causal link between injury and wage loss. To the contrary, according to one of the leading authorities on workers’ compensation law, the “Misconduct of the employee, whether negligent or wilful, is immaterial in compensation law, unless it takes the form of deviation from the course of employment, or unless it is of a kind specifically made a defense in the jurisdictions containing such a defense in their statutes.” 2 ARTHUR Larson, Larson’s Workers’ Compensation Law § 32.00 (2001). If the Director did indeed consider the termination of the petitioner as a basis in law for denying benefits, such a determination would not withstand judicial scrutiny as it would find no support in the District of Columbia Workers’ Compensation Act. Specifically, the Act does not provide that the subsequent termination of an employee, whether related or unrelated to a work injury, is a defense for an employer who denies an obligation to pay disability compensation.[50]
*390The general principle that an employee’s termination is immaterial to his entitlement to workers’ compensation benefits holds true even when the termination was for fraudulent or illegal activity, so long as “ ‘the illegal feature of the conduct was not the causative factor in producing the injury.’ ”51 That the employee made false statements to his employer to obtain his job, and would not have been hired at all but for his fraud, is not enough to convert that fraud into a causative factor. To the contrary, we have held that fraud in securing employment, the conduct for which O’Rourke was terminated, ordinarily “does not foreclose [a] claim for benefits” under the Workers’ Compensation Act.52
There are some exceptions to that usual rule, but the Board did not rely on them, and it appears that none of them apply here.53 The only exception that we perceive as having potential relevance in this case concerns the particular nature of O’Rourke’s alleged misrepresentations when he was hired. The Police Department terminated O’Rourke because it found that he falsely denied having been examined for any disease or physical impairment, when in fact he had been tested for a heart condition. Although this court has not-had occasion to address the question, other courts have held that an employee forfeits his claim for disability benefits if he lied about a pre-existing medical condition to which the claim is related.54 So far as the record indicates, however, that is not the case here; There is no indication that the injuries O’Rourke sustained in chasing a carjacker were related in any way to the condition of his heart, or to anything else he allegedly hid from the Police Department when he was hired.55 Nor did the Retirement and Relief Board base its decision in this case on that theory; the content of O’Rourke’s alleged misrepresentations was irrelevant to the Board’s ruling.
In sum, because the Retirement and Disability Act functions as a comprehensive workers’ compensation statute for police and firefighters, it must be construed “liberally in light of its humane purpose.”56 In this case, the Board did not approach its interpretive task in that spirit. It overlooked the general rule that employees do not lose their rights to dis*391ability benefits under workers’ compensation statutes when their employment is terminated, even for wrongdoing. Its conclusion that a member becomes ineligible to receive a disability annuity under the Retirement and Disability Act if he happens to be terminated while the administrative process before the Board is still in progress is both anomalous and inconsistent with the Act’s primary purpose.
We conclude that the Board has adopted an unreasonable interpretation of §§ 5-709 and 5-710, because it is incompatible with the broader statutory context and the humanitarian and remedial policy of the Act. As a result, we are not required to defer to it.57 In essence, the Board asks us to “accord a narrow and grudging construction to remedial legislation,”58 but it has provided us with no sound reason for doing so; and as we have done in the past, we decline to accept that invitation. There is no indication that the legislature, by vesting the Board with the authority to review disability retirement recommendations and applications, intended to do anything more than create a procedural pipeline through which the cases must pass. We therefore hold that membership at the time a recommendation or application for disability retirement reaches the Board is sufficient to satisfy the membership requirements of §§ 5-709 and 5-710, regardless of whether the member is terminated before the Board comes to its decision.59 “[O]nce this necessary information has been submitted, there will be some administrative delay ...; its duration will depend upon the speed of the Board’s internal adjudicative processes and will, presumably, vary from year to year and from annuitant to annuitant. [This delay does not result from] any fault of the annuitant....”60 The Board must conduct its normal analysis to determine whether the member is, in fact, disabled, and whether that disability arose from the performance of duty. But the Board may not deny a disability annuity solely on the grounds that the member’s employment was terminated while the matter was pending before it. The member’s substantive entitlement cannot be beholden to administrative delays.
IY.
For the foregoing reasons, we reverse the decision of the Retirement and Relief Board in this case and remand for further proceedings consistent with our opinion. On remand, the Board should determine whether O’Rourke is disabled within the meaning of the Retirement and Disability Act, and if so, whether his disability is performance-related and what disability annuity he is entitled to receive.
So ordered.
