In one sentence

In Local 3621 v. City of New York, Judge Liman denied summary judgment without prejudice on disparate-impact claims, granted it on others, and denied expert exclusion.

Who this affects

The ruling affects Local 3621, Renae Mascol, Luis Rodriguez, the City of New York, the New York City Fire Department, and the Department of Citywide Administrative Services. The disparate-impact claims may proceed subject to a possible renewed summary-judgment motion; other claims were granted against, dismissed, or dismissed without prejudice as stated in the opinion.

What happened

In Local 3621, EMS officers Renae Mascol and Luis Rodriguez, along with their union, challenged New York City’s promotional practices for EMS officers. They claimed the practices unlawfully affected promotions based on race, gender, and disability.

The court found enough evidence for a trial on the claims that eligibility rules had a harmful unequal effect on non-white and female officers. It rejected Mascol’s gender-based treatment claims and dismissed Rodriguez’s city disability claim without prejudice because New York courts should address the unsettled state-law issue. It also dismissed the remaining equal-protection claims and claims the plaintiffs had abandoned.

Judge Liman denied the defendants’ summary-judgment motion without prejudice as to the disparate-impact claims, granted it as to the disparate-treatment and equal-protection claims, and denied the plaintiffs’ motion to exclude the defendants’ expert testimony.

Background

The plaintiffs were Local 3621, EMS officers Renae Mascol and Luis Rodriguez, and the union’s members. They challenged the New York City Fire Department’s promotional system for EMS officers seeking promotions above lieutenant. Promotions to captain and higher positions generally used eligibility requirements, interviews, and discretionary selection rather than civil-service examinations.

The plaintiffs alleged that the system caused unequal promotional effects based on race and gender and that particular decisions treated Mascol differently because she is a woman and Rodriguez differently because of injuries and related leave. Their claims arose under Title VII of the Civil Rights Act, the Equal Protection Clause through 42 U.S.C. § 1983, the New York State Human Rights Law, and the New York City Human Rights Law.

Before analyzing the remaining claims, the court stated that the plaintiffs had waived, withdrawn, or abandoned several claims. Those included all claims against the Fire Department and the Department of Citywide Administrative Services; all race-based disparate-treatment claims; certain of Rodriguez’s disability claims under Title VII and the New York State Human Rights Law; due-process claims under Section 1983; claims under 42 U.S.C. § 1981; and nearly all claims brought by Local 3621. The court dismissed those claims.

Disparate-impact claims

Mascol and Rodriguez claimed that three facially neutral eligibility rules had a disproportionate effect on non-white and female EMS lieutenants: the four-year time-in-title requirement, minimum annual performance ratings, and a clean disciplinary record during the preceding two years.

The plaintiffs’ expert, Dr. Shane Thompson, reported statistically significant differences in the racial and gender composition of lieutenants and captains and attributed those differences to the eligibility requirements. The defendants’ expert, Dr. Christopher Erath, analyzed officers who actually applied for promotion and concluded that women and non-white applicants were promoted at equal or higher rates than men and white applicants.

The court held that the two expert reports addressed different parts of the process and were not necessarily inconsistent. Dr. Erath examined people who applied, while Dr. Thompson examined whether the eligibility rules prevented some officers from applying. The court concluded that the relevant pool could include officers who did not apply because the challenged requirements allegedly prevented them from doing so. It also found that the plaintiffs had offered enough evidence to make an initial showing of disparate impact and that the defendants had not shown the absence of a genuine dispute of material fact.

The court nevertheless held that an individual plaintiff must show that the challenged policy personally harmed them. Mascol and Rodriguez met the eligibility requirements when they first applied for promotion, so they could not claim that the rules harmed them during those application periods. The court noted that they might still seek damages for earlier periods of ineligibility if they could show that they would have applied absent the challenged requirements. Because the parties had not adequately addressed that issue, the court denied summary judgment on the disparate-impact claims, including the New York City Human Rights Law claims, without prejudice. The court stated that the defendants could seek summary judgment again and raise additional arguments at the next stage of the analysis.

Mascol’s disparate-treatment claims

Mascol alleged that the defendants denied her promotions because of her gender. She relied on her 2014 discipline, alleged conduct by Chief James Booth, and the fact that three men with lower 2018 interview scores were promoted over her.

The court rejected the discipline-based theory because the complaint did not plead it, the plaintiffs had previously treated the issue as irrelevant during discovery, and Mascol had signed an agreement waiving claims concerning the disciplinary matter. The court also held that she had not exhausted that theory before the Equal Employment Opportunity Commission for purposes of Title VII. In addition, the court found that the male employees she identified were not similarly situated because the disciplinary allegations concerned Mascol’s alleged direction of subordinate employees.

As to Booth, the court found that Mascol’s declaration contained unsupported and conclusory allegations that he secretly removed her from consideration or treated her differently from male officers. Those allegations did not create a genuine dispute of material fact. As to the lower-scoring applicants promoted in 2018, the defendants offered a nondiscriminatory explanation: the three had experience in the Bureau of Communications, which needed additional captains, while Mascol did not. The court also noted that eight male applicants who scored as well as or better than Mascol were not promoted.

The court granted the defendants’ motion for summary judgment on Mascol’s disparate-treatment claims under Title VII, the New York State Human Rights Law, and the New York City Human Rights Law.

Rodriguez’s disability claim

Rodriguez brought a disability-discrimination claim only under the New York City Human Rights Law. He alleged that the defendants denied him promotions because he had taken leave and light-duty status after line-of-duty injuries, including a broken wrist.

The court noted that the complaint did not allege that Rodriguez was disabled and that the parties had provided limited facts about his injuries. It declined to decide whether a broken bone necessarily qualifies as a disability under the New York City Human Rights Law because that issue involved unsettled and complex state law. The court therefore declined to exercise supplemental jurisdiction and dismissed Rodriguez’s claim without prejudice to filing in state court.

Section 1983 equal-protection claims

Mascol, Rodriguez, and Local 3621 asserted equal-protection claims under Section 1983. In their summary-judgment briefing, they based those claims on the defendants’ alleged failure to use civil-service examinations and on resulting discrimination.

The court found that the complaint did not plead equal-protection claims based on those theories. Instead, the complaint described Section 1983 claims as involving statutory rights, did not identify the specific civil-service provisions at issue, and expressly stated that whether civil-service examinations were legally required was not part of the case. The court also found that the defendants lacked notice of the equal-protection theory and were prejudiced because they had addressed due process rather than equal protection in their opening brief.

The court therefore dismissed the equal-protection claims. It also stated in the alternative that the individual plaintiffs could not use Section 1983 to pursue disparate-impact or Title VII claims, and that disability discrimination claims of this type were not cognizable under Section 1983.

Motion to exclude expert testimony

The plaintiffs moved under Federal Rule of Evidence 702 to exclude Dr. Erath’s testimony and reports. The court denied that motion. It reasoned that the plaintiffs’ arguments about whether the testimony would help the jury or be relevant were better addressed in a later motion concerning evidence at trial. The court also found that any disagreement between Dr. Erath’s and Dr. Thompson’s analyses had not warranted summary judgment for the defendants. The motion was denied, rather than denied without prejudice, in the conclusion.

Disposition

Judge Liman held that the defendants’ motion for summary judgment was granted in part and denied in part. The motion was denied without prejudice as to the disparate-impact claims and granted as to the disparate-treatment and equal-protection claims. Rodriguez’s New York City Human Rights Law disability claim was dismissed without prejudice for filing in state court. The plaintiffs’ motion to exclude Dr. Erath’s testimony was denied.
