As anyone who was awake during the fall of 2004 knows, the label of “flip-flopper” got considerable play during the presidential campaign. The term lives again in this appeal, which involves yet another challenge to the promotion procedures of the Chicago Police Department. The plaintiffs are minority police sergeants who claim their failure to be promoted after taking the 1998 lieutenant examination violated Title VII of the Civil Rights Act of 1964, 42 U.S.C. §§ 2000e to e-17. During the course of litigation, the plaintiffs elected to renounce one theory of recovery in order to pursue another. But later, when this fresh approach appeared *891 doomed, they tried to resuscitate their original claim. A federal district court did not allow it and entered summary judgment in favor of the City of Chicago.
First, some background. The promotional process at issue had three parts: a written qualifying test, an assessment exercise, and a merit selection process.
See Allen v. City of Chicago,
In their original complaint, filed in November of 1998, the plaintiffs alleged that the City’s employment test (the written qualifying test and the rank-order assessment exercise) unlawfully discriminated against them on the basis of race. The district court certified two subclasses of officers adversely affected by the 1998 promotion process. Subclass A plaintiffs are minority officers who failed the written qualifying test and are thus ineligible for promotions based on assessment or merit. Subclass B plaintiffs are those who passed the written qualifying test but did not score high enough on assessment to earn a promotion.
In July of 2000, the plaintiffs requested leave to file a “conditional amended complaint” and a stay of discovery pending resolution of the petition for a writ of
certiorari
filed in
Bryant v. City of Chicago,
A month later, the plaintiffs filed an amended complaint; this time alleging that merit promotions are an equally valid, less discriminatory alternative to the rank-order promotions and that the City violated Title VII by limiting them to 30 percent of all promotions. When discovery resumed, the plaintiffs, responding to the City’s request for admissions under Fed.R.Civ.P. 36(a), conceded the validity of the written qualifying test and the assessment exercise under Title VII. By the time discovery closed in August of 2002, the plaintiffs had failed to designate an expert to substantiate their claims.
The City moved for summary judgment in November of 2002, based on the plaintiffs’ failure to secure an expert, as well as the decision of a federal district court in
Allen v. City of Chicago,
The plaintiffs then tried to flip-flop, asking under Fed.R.Civ.P. 36(b) to withdraw their earlier admissions that the written qualifying test and assessment exercise are kosher under Title VII. The plaintiffs acknowledged that “Allen is fatal to any ‘equally valid, less discriminatory alternative’ argument in this case” and argued that they should be allowed to resurrect their claims relating to test validity because, in their view, Allen altered the City’s burden of proof for justifying a discriminatory selection method. The district court denied the request and then entered summary judgment in favor of the City.
On appeal, the plaintiffs contend that the district court erred by not allowing them to withdraw their admissions. Admissions, in some ways, are like sworn testimony. Once one is made, there is no need to revisit the point. Under Rule 36(b), matters admitted are “conclusively established.” In our case, the plaintiffs admitted, among other things, that the written qualifying test and assessment exercise of the 1998 exam “do not violate or contribute to any violation of Title VII.” Now, they wish to take back these admissions. A sort of flip-flop, if you will.
A court, in its discretion, may permit a party to rescind admissions when doing so better serves the presentation of the merits of the case and the party who benefits from the admissions (usually by relying on them) is not prejudiced. Fed.R.Civ.P. 36(b). We review a court’s refusal to allow the withdrawal of admissions only for an abuse of discretion.
United States v. Kasuboski,
Here, there was no abuse of discretion. In the first instance, the plaintiffs cannot, in the words of Rule 36(b), demonstrate that permitting them to withdraw their admissions “subserves the merits.” Their original, abandoned claims are likely foreclosed by
Bryant,
whether they admit it or not. Still, they contend the district court abused its discretion because there was a change in our analysis of disparate impact. To prevail on such a cause of action, the plaintiffs must establish that the City’s promotion process caused a disparate impact on minority sergeants. If this is shown, the burden shifts to the City to demonstrate that the promotion process is “job related” and “consistent with business necessity.” 42 U.S.C. § 2000e-2(k)(l)(A);
Allen,
The plaintiffs claim that our interpretation of this test has changed. Specifically, they contend that before Bryant, an employer could demonstrate the validity of rank-order selection only by using empiri *893 cal evidence of an association between performance on the exams and on the job. In their view, Bryant abandoned this requirement, leaving them no choice but to admit the validity of the 1998 test. But then later in Allen, so the argument goes, the requirement of statistical evidence demonstrating a correlation between test and job performance was reinstated.
The plaintiffs are misreading these cases. As we stated earlier, employers can establish job-relatedness by one of three methods, including “content validity,” which entails showing that
“the test
measures the job or adequately reflects the skills or knowledge required by the job.”
Gillespie v. Wisconsin,
Contrary to the plaintiffs’ assertion, our
pre-Bryant
cases authorized proceeding under the content-validity approach to establish job-relatedness, which as we have said does not require employers to come forth with statistical evidence.
See Billish,
Moreover, merits notwithstanding, the City met its burden of establishing prejudice. This lawsuit has been around since 1998. The plaintiffs forced the City to litigate the issue of test validity, only to abandon the theory with a vow not to litigate it. Discovery was then completed on the plaintiffs’ new theory that merit promotion was an equally valid, less discriminatory alternative. Once it became apparent that the plaintiffs could not win under this theory, they tried to go back where they started. ■ Throughout this litigation, the City has been subjected to long delays and voluminous discovery. Enough is enough.
Affirmed.
