Minnesota can no longer enforce its law barring people younger than 21 years old from obtaining a permit to carry a handgun in public after the U.S. Supreme Court refused on Monday to hear its appeal of a judicial decision deeming the age restriction a violation of constitutional protections for gun rights.

The Supreme Court has rejected an appeal from Minnesota asking to revive the state’s ban on gun-carry permits for young adults.

The Supreme Court declined to get involved in the ongoing Minnesota debate about age restrictions for weapons for 18- to 20-year-olds.
