AUSTIN, Texas (AP) — A federal judge has blocked the Biden administration from enforcing a new rule in Texas that would require firearms dealers to run background checks on buyers at gun shows or other places outside brick-and-mortar stores.

The decision by U.S. District Judge Matthew Kacsmaryk, an appointee of former President Donald Trump, came before the rule had been set to take effect Monday. The order also prevents the federal government from enforcing the rule against several gun-rights groups, including Gun Owners of America. It does not apply to Louisiana, Mississippi and Utah, which were also part of the lawsuit.

“Plaintiffs understandably fear that these presumptions will trigger civil or criminal penalties for conduct deemed lawful just yesterday,” Kacsmaryk said in his ruling.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives declined to comment. The Justice Department didn’t immediately respond to a request for comment.
