Montana Attorney General Austin Knudsen is leading a 27-state coalition urging the U.S. Supreme Court to overturn Washington state’s ban on firearm magazines that hold more than 10 rounds. The coalition filed an amicus brief Monday in Gator’s Custom Guns, Inc. v. State of Washington, arguing the law violates the Second Amendment.
In May, the Washington Supreme Court upheld the 2022 ban, reversing a lower court ruling that had struck down the law as unconstitutional. Knudsen and his counterparts say the decision misinterprets both history and precedent established in landmark Supreme Court cases.
