Results
Summary Judgment Affirmed by Pennsylvania Commonwealth Court in Police Pursuit Case
We were affirmed the granting of summary judgment in favor of our client in a high-speed police pursuit case. The plaintiff was severely injured after a brief police pursuit involving the driver, who died as a result of the pursuit. The plaintiff then sued the local municipality for negligence, arguing that the officers caused the wreck by turning a traffic stop into a high-speed chase. Following discovery, the court granted summary judgment in favor of the Township, finding that the so-called vehicle exception to municipal liability found in the Pennsylvania Political Subdivision Tort Claims Act did not apply. The trial court reasoned that pursuant to the Pennsylvania Supreme Court’s holding in Sellers v. The Township of Abington, 106 A. 3d 679 (Pa. 2014), the defendants did not owe the plaintiff a duty of care because his existence or connection to the driver were unknown to the officers at the time of the pursuit. The Commonwealth Court issued an opinion affirming the trial court and held that the exception to the exception for vehicle liability involving high-speed police pursuits did not apply because the plaintiff was unable to establish the threshold requirement that the defendants owed him a duty of care.
Defense Obtains Dismissal of a Complex Federal Civil Rights Action
We obtained the dismissal of a federal civil rights action alleging that a municipality retaliated against a real estate developer after the sale of a large tract of local property.
