The Firearms Policy Coalition filed a lawsuit against the Pennsylvania State Police on Friday requesting an emergency injunction just days after the state’s attorney general issued a legal opinion reclassifying certain unfinished weapons parts as firearms under state law.

“Rule by executive fiat was rejected by the Thirteen American Colonies, including Pennsylvania, when they declared independence from England, and we reject such lawlessness today,” Adam Kraut, the coalition’s director of legal policy, said in a press release. “The Attorney General’s revisionist legal opinion adds an entire class of inanimate objects to the definition of ‘firearm’ under Pennsylvania law that the General Assembly never considered, nor intended.”
