Gun advocates asked the U.S. Supreme Court on Monday to overturn a lower court’s ruling against state laws designed to buck federal gun rules.
Earlier this year, the 9th U.S. Circuit Court of Appeals upheld a district judge’s decision against the 2009 Montana Firearms Freedom Act. The law attempts to declare that federal firearms regulations don’t apply to guns kept in the state where they were manufactured.
Other pro-gun states have passed similar measures.
