A federal judge has refused to dismiss a civil rights lawsuit filed by a Sewickley dog walker who says a Pittsburgh public works supervisor punched her and hurled a homophobic slur during a 2024 confrontation over dogs in a city park. Michelle Cook, 42, alleges the physical and verbal attack happened after Tara Pinnix, a supervisor with the city's Department of Public Works, told her dogs weren't allowed inside an enclosed court at Flynn Parklet in Highland Park.
U.S. District Judge William S. Stickman IV declined to dismiss Cook's federal lawsuit, ruling that her claim alleges a constitutional-rights violation distinct from the city-code issue already handled by a local civil rights panel, according to TribLIVE. The city had argued that a March 2026 Pittsburgh Human Relations Commission ruling, which awarded Cook $10,000 in damages for discrimination based on sexual orientation, gave her a full and fair opportunity to raise her constitutional claims and should end the matter. Stickman rejected that argument, writing that the commission cannot award the same remedies as a court or a jury.
Cook, a professional dog walker who runs Sky's the Limit Pet Care, which opened in Sewickley in January 2024, was walking 12 dogs in the parklet's enclosed court in June 2024 when the confrontation began. Pinnix told her the dogs weren't allowed there, then opened the gate, allowing some of the dogs to run into the street, and enticed others to leave the court before holding the gate closed and trapping Cook inside, according to the lawsuit's account reported by TribLIVE.
What Happened Inside the Enclosed Court
The confrontation escalated from there. Cook alleges Pinnix grabbed her shirt, breaking her necklace, and punched her in the face, giving her a black eye. Pinnix, who has claimed self-defense, injured a finger on her left hand during the altercation, an injury that required surgery and was covered under the city's workers' compensation policy, per the Pittsburgh Post-Gazette's reporting on the case. Pittsburgh police cited both women for disorderly conduct, but a court later acquitted them both of those citations.
Police body camera footage recorded during the initial response captured Pinnix admitting to officers that she used a homophobic slur during the confrontation, according to PublicSource. The city's Office of Municipal Investigation later found that Pinnix violated the disciplinary manual's provisions on fighting and abusive or offensive language. Despite that sustained finding, the city did not discipline her, according to Cook's lawsuit.
A Park With No Posted Rules
At the time of the dispute, Flynn Parklet's enclosed court had no posted signs prohibiting dogs, though it did feature a municipal sign asking owners to clean up after pets alongside a dog-waste bag dispenser, the same PublicSource reporting notes. Under Section 54102.02 and Ordinance 473.05b of the Pittsburgh Code of Ordinances, domestic animals are explicitly prohibited on city park playgrounds, ball fields, or sports courts at all times, though that rule wasn't visibly posted at the parklet when the confrontation occurred. As part of its March ruling, the Human Relations Commission ordered the city to install explicit signage clarifying court restrictions across Citiparks properties.
Cook filed her complaint with the Human Relations Commission in January 2025, and the commission found in March 2026 that she had been discriminated against on the basis of sexual orientation. Beyond the $10,000 award, the commission's ruling ordered the city to cover Cook's attorney fees and mandate staff training in conflict de-escalation, public engagement, and trauma-informed communication across the Department of Public Works, along with retraining supervisors on internal investigation and disciplinary protocols. The city did not appeal that decision.
City Challenged Its Own Civil Rights Panel
During the administrative proceedings, the city questioned the legal enforcement authority of its own Human Relations Commission to conduct public hearings and penalize city departments or municipal employees, with the city's solicitor arguing the commission lacked statutory clout to sanction municipal operations, per PublicSource. That internal friction adds another layer to a case in which discrimination complaints involving sexual orientation are relatively rare for the commission, accounting for just 17 of 325 total complaints filed over a nearly three-year period ending in late 2025, the outlet reported, citing data released under Pennsylvania's Right-to-Know Law.
The Pittsburgh Commission on Human Relations, established by a city ordinance in 1955, added sexual orientation as a protected class under the municipal anti-discrimination code in 1990, according to the City of Pittsburgh. As Parks Maintenance Manager for the Department of Public Works' Highland Division, Pinnix oversees daily maintenance and field staff across 25 city park facilities, including Highland Park and Flynn Parklet.
Cook's federal lawsuit, filed in November 2025 in the U.S. District Court for the Western District of Pennsylvania, invokes 42 U.S.C. Section 1983 to seek civil rights damages beyond what local administrative panels can award, according to the Pittsburgh Post-Gazette. The suit asserts claims for excessive force, false imprisonment, and equal protection violations against both Pinnix and the Public Works department. Joe Rush has said Pinnix was doing her job and should not be disciplined, a position that stands in contrast to the sustained misconduct findings against her. With Stickman's ruling allowing the federal case to proceed, the dispute that began over a locked gate at a neighborhood dog park now heads toward further litigation in federal court.
