ROBERT BOYER, Executor of the Estate of Tamra Smith, Deceased; ROBERT BOYER v. MICHAEL MULVEY

March 4, 2026 ·3:19-cv-00242 ·Panel Decision ·HARDIMAN · By Aisha Johnson

The Third Circuit reversed the district court's denial of summary judgment, holding that a state trooper was entitled to qualified immunity for searching a former mayor's home. The court found that it was not clearly established at the time that a potential conflict of interest under state ethics laws provided probable cause for a warrantless search of a residence.

Robert Boyer, the former mayor of Wyoming Borough, operated a catering business out of the local firehouse while in office. After a news report highlighted that the firehouse renovation grant included upgrades to a banquet hall where Boyer's business operated, Pennsylvania State Trooper Michael Mulvey investigated whether Boyer violated the Pennsylvania Public Official and Employee Ethics Act. Mulvey consulted with the State Ethics Commission and the Attorney General's Office, who indicated an ethics violation might exist. Based on this investigation, Mulvey obtained a warrant to search Boyer's home for evidence of the violation. Boyer sued under 42 U.S.C. § 1983, claiming the search lacked probable cause and violated his Fourth Amendment rights. The district court denied Mulvey's motion for summary judgment, finding that the right to be free from unlawful searches was clearly established, without identifying a factually analogous case.

The Third Circuit reversed, holding that Trooper Mulvey was entitled to qualified immunity. First, the court noted that Mulvey received a presumption of qualified immunity because he consulted with two investigators from the State Ethics Commission before filing the warrant application. This reliance was objectively reasonable, and Boyer failed to show that a reasonable officer would not have relied on that advice. Second, the court criticized the district court for defining clearly established law too abstractly. The district court had stated generally that people have a right to be free from unlawful searches except on probable cause. The Third Circuit explained that Supreme Court precedent requires courts to define clearly established law with specificity to the officer's conduct in the particular circumstances. The court found that the cases the district court relied on, such as Messerschmidt v. Millender and Andrews v. Scuilli, did not present factually analogous situations that would put a reasonable officer on notice that the conduct was unlawful. Additionally, the court noted that under Pennsylvania law, determining whether an economic impact is de minimis is highly fact-specific, and no bright-line rule existed that would have alerted Mulvey that his conduct was clearly illegal.

The decision reverses the district court's denial of summary judgment, effectively granting immunity to the officer and ending the liability claim against him. It reinforces the requirement that plaintiffs must point to specific, factually analogous cases to prove that a right was clearly established, rather than relying on broad legal abstractions. The case is remanded for the entry of judgment in favor of the officer.
