A federal judge blocked Idaho on Tuesday from enforcing a new law that would have made it a crime to use public restrooms or changing facilities that do not align with one’s sex assigned at birth, ruling that key provisions of the measure were likely unconstitutional.

U.S. District Judge Amanda Brailsford issued a preliminary injunction preventing Idaho’s House Bill 752 from taking effect July 1 while a lawsuit challenging the measure proceeds through federal court, marking a win for the transgender Idahoans who brought the case forward. The judge also provisionally certified a class of transgender Idaho residents, extending the injunction beyond the six plaintiffs who brought the case.
