Seamus P. McCaffery (born June 3, 1950) is an American retired Justice on the Supreme Court of Pennsylvania.

[2] He graduated from Cardinal Dougherty High School in Philadelphia and joined the United States Marine Corps.

McCaffery presided over the court, which was convened in the basement of Veterans Stadium, and handed out fines or jail time to fans arrested during games.

Because of this, defense attorneys asked him to recuse himself from trials involving the protests, but he refused, without hearing the arguments.

[8][11] The justices voting to suspend McCaffery cited King's Bench power to "protect and preserve the integrity" of the state's judicial system.

[13] In his concurring statement on the suspension, Chief Justice Castille described McCaffery as exhibiting the traits of a sociopath.
