Opinion for the Court filed by Circuit Judge ROGERS.
In
Swanks v. WMATA,
I.
Michael Swanks suffers from a congenital condition known as spina bifida, which affects his urinary tract and leads to incontinence and infections. At the time he was hired in 1989 by WMATA as a special police officer, Swanks informed an interviewer and a WMATA examining physician of his condition. He initially worked at locations in the District of Columbia, Virginia, and Maryland, but his work site “stabilized” in 1991 when he began working at the West Falls Church METRO stop in Virginia. Viewing the evidence most favorably to Swanks, as we must,
see Boodoo v. Cary,
In September 1992, as part of a system-wide spot check, a supervisor asked to see Swanks’ special police commission. Swanks stated that it was in his wallet, which he had left the day before with his brother-in-law. Upon retrieving the wallet, however, he discovered that the commission was missing and went to the D.C. Metropolitan Police Department for a replacement. He was unaware before thеn that his commission had expired over a year earlier. Captain Rice subsequently recommended that Swanks be dismissed for not having his commission and for lying about having lost it when WMATA asked if he had it. In October, Swanks was dismissed from his job. When his wife telephoned to ask why her husband was being fired, Captain Rice told her that the termination was due to her husband’s absences and not the expiration of the “gun permit.” Swanks filed suit under the ADA, alleging that WMATA failed to provide reasonable accommodation for his disability and that it discharged him because of his disability.
II.
Although the court reviews
de novo
the denial of WMATA’s motion for judgment as a matter of law, or in the alternative, for a new trial,
see Scott v. District of Columbia,
A.
Under the now familiar three-part protocol established in
McDonnell Douglas Corp. v. Green,
the focus of proceedings at trial ... will be on whether the jury could infer discrimination from the combination of the plaintiffs prima facie case; (2) any evidence the plaintiff presents to attack the employer’s proffered explanation fоr its actions; and (3) any further evidence of discrimination that may be available to the plaintiff (such as independent evidence of discriminatory statements or attitudes on the part of the employer) or any contrary evidence that may be available to the employer (such as evidence of a strong track record in equal opportunity employment).
*934 Id. at 1289. The plaintiff retains the ultimate burden of persuasion, to demonstrate that he was in fact the victim of intentional discrimination. See id. at 1290.
To sustain a claim under the ADA, Swanks must prove that he had a disability within the meaning of the ADA, that he was “qualified” for the position with or without a reasonable accommodation, and that he suffered an adverse employment action because of his disability.
See Kiel v. Select Artificials, Inc.,
The ADA provides that “[n]o covered entity shall discriminate against a
qualified individual
with а disability because of the disability ... in regard to ... discharge of employees ... and other terms, conditions, and privileges of employment.” 42 U.S.C. § 12112(a) (1994) (emphasis added). The Act defines a “qualified individual” as a person “with a disability who, with or without reasonable accommodation, can perform the essential functions of the employment position that such individual holds or desires.”
Id.
§ 12111(8). It further provides that “cоnsideration shall be given to the employer’s judgment as to what functions of a job are essential, and if an employer has prepared a written description before advertising or interviewing applicants for the job, this description shall be considered evidence of the essential functions of the job.”
Id.; cf.
Carr
v. Reno,
Whether an individual is “qualified” for a job may at times present a pure question of law to be resolved by the court, but it may also, as in this case, be a question of fact that must be resolved by a fact-finder at trial. Thus, for example, in
Baert v. Euclid Beverage, Ltd.,
WMATA contends that the district court erred in denying its motion for judgment as a matter of law because the evidence showed that possеssing a special police commission is a requirement for Swanks’ position and that Swanks was therefore not qualified because he had allowed his commission to expire. The special police officer commission, WMATA contends, is “tantamount to a professional licence and ... without this license there is no authority to act in the capacity of special pоlice officer.” In WMATA’s view, the job description combined with Captain Rice’s testimony “made it clear that an essential requirement of the job of special police officer was the maintenance and possession of a special police commission.” Specifically, Captain Rice testified that the special commission was required of all special рolice, including those stationed in Virginia or Maryland, because “we work out of the District of Columbia,” which requires the license and which covers 90 to 95 percent of Metro locations. 3 He also testified that if the D.C. Metropolitan Police discover a special officer operating *935 without a commission' in the District, WMATA and the officer can be fined. 4
The difficulty with WMATA’s position is twofold. First, WMATA’s personnel description of the special police officer job states that an individual only need have the “[ajbility to obtain and maintain a Special Police Commission.” The “minimum qualifications and experience” include only that the applicant have graduated from high school (or received an equivalent certificate), and be at least 21 years old and a United States сitizen (or have an equivalent combination of education and experience); there is no mention of the commission. If after obtaining the commission, the officer allows it to expire, official WMATA policy provides that expiration “will result in your not being permitted to work until the job position requirement is met;” it does not provide for automatic discharge. Second, Swanks testified that in practice WMATA only required that he have the ability to maintain the commission. When he initially informed a supervisor that he had lost his commission, he testified that he was informed that he “did not need a gun permit to work in the State of Virginia” and that he was to report to work. Similarly, when it later was clear his commission had expired, he was told that he would be on leave until he renewed it. This evidence of WMATA’s prаctice was supported by Captain Rice’s testimony describing how new employees would apply for the commission after being hired and that the application process could last four to eight months.
The district court, therefore, properly denied WMATA’s motion for judgment &s a matter of law in light of evidence making qualification an issue of fact. Based upon the evidence, a rеasonable juror could find that possessing the commission was not a prerequisite to being hired, and that new employees simply had to possess the ability to obtain such a commission, and hence the jury had sufficient evidence to find that Swanks was a “qualified individual” with a disability under the ADA.
B.
The question remains whether WMATA presented a nondiscriminatory reason for discharging Swanks and if so, whether Swanks presented evidence upon which a reasonable juror could rely to conclude that WMATA’s true motivation for firing him was discriminatory. Our standard of review here is deferential: a jury’s verdict may be overturned only if no reasonable juror could find that WMATA discriminated against Swanks.
Anderson,
The evidence before the jury as to WMATA’s true reason for terminating Swanks was conflicting. On the one hand, Captain Rice testified, and his memorandum recommending Swanks’ dismissal stated, that the cause for Swanks’ discharge was the expiration of the special commission and Swanks’ alleged fabrications when WMATA asked to see his commission. On the other hand, Swanks testified that he was unaware that his commission, which he believed he had lost, had expired. 5 Furthermore, his *936 wife’s testimony, that Captain Rice had told her that her husband’s absences, rather than the “gun permit,” was the reason for his discharge, was bolstered by evidence that WMATA had threatened disciplinary action because of his absences and had been unreceptive to his attempts, with doctor’s stаtements, to explain how his condition caused these absences. 6
The issue of witness credibility “is quintessentially one for the finder of fact,”
Aka,
To the extent that WMATA contends for the first time in its reply brief, and at oral argument, that even if Swanks could show that he was fired for excessive absenteeism, regular attendance at work is an “essential function” of his job, its argument comes too late.
8
See Chedick v. Nash,
Finally, WMATA contends in its reply brief that even if it “had full knowledge that Mr. Swanks’ absenteeism was caused by his disability, there can be no finding of discrimination because the jury found against Mr. Swanks on the accommodation issue [claim].” Because Swanks had no opportunity to respond to this contention in his brief, the court need not consider it.
See Herbert v. National Academy of Sciences,
Accordingly, we affirm the judgment.
Notes
. On April 8, 1999, the court denied WMA-TA’s motion to postpone oral argument in viеw of the Supreme Court’s grant of a petition for writ of certiorari in
Cleveland v. Policy Management Sys. Corp.,
. Swanks testified that he used his sick leave only when he was sick, using twelve days in 1989-90, 18 days in 1990-91, and 22 days in 1991-92. Swanks also testified that he used annual leave for vacation and to care for his wife when she was sick.
. See D.C.Code Ann. § 4-114 (1994) (conferring authority on the Mayor to appoint special pоlice officers).
. See D.C. Mun. Regs. tit. 6A, §§ 1101.2, 1104.2, 1108.1 (1S>88). Section 1104.2 of Title 6A provides that:
Each special police officer appointed under the provisions of D.C.Code § 4-114 (1981), shall, within twenty-four (24) hours after the expiration or revocation of his or her commission ... deliver to the Chief of Police his or her badge, commission, or other emblem of authority, and upon his or her failure so to do, he or she shall, upon conviction thereof in the Superior Cоurt for the District of Columbia, be punished by a fine or [sic] not more than three hundred dollars ($300).
. Although Swanks maintains that WMATA presented "no evidence of untruthfulness,” Captain Rice’s October 1992 memorandum stated that "Officer Swanks' inability to provide a copy of his D.C. Special Police Commission and his subsequent story of his "brother-in-law” taking his wallet only em-phasises [sic] that he: a) was aware that his *936 commission was invalid; [and] b) wаnted to have time to get to MPD [Metropolitan Police Department] to obtain a renewal,” and further, that Swanks admitted to MPD Detective Owens that he was aware his commission had expired "but only after he was confronted with the information.”
. This evidence contradicts WMATA’s statement in its brief that it "had no way of knowing that Mr. Swanks' excessive absenteeism was a result of his spina bifida occulta.”
. Citing
Proud v. Stone,
.WMATA’s regulations provide that a special police officer "must be dependable, regular in attendance and never absent from work without making advance arrangements with the sergeant, except in the case of illness or extreme emergency.” Def.’s Ex. 7, ¶ 10 (Protective Sеrvices Bureau Rules & Regulations for Special Police Officers). They also define "unsatisfactory attendance” as "unscheduled absences so frequent as to indicate that the employee is undependable.” Id. ¶ 24. Captain Rice testified that special police officers accrue 3.75 hours of sick leave and 3.75 hours of annual leave every two weeks, in addition to federal holidays. Over the course of approximately 26 pay-periods an officer would therefore annually accrue 97.5 hours of sick leave. Although Captain Rice testified that officers accrue approximately 10 to 11 days of sick leave per year, with a tour of duty lasting 7.5 hours, the number of sick days would equal 13 (97.5 divided by 7.5). By that calculation, Swanks used less than the full annual amount of sick leave during his first year and exceeded that amount by five days in his second year and nine days in his third year.
