The US Supreme Court on Monday turned down the appeal of a Maryland man who said the state’s restrictive gun-permit law violated his constitutional right to carry a firearm in public for self defense.

The case, Williams v. Maryland, was being closely followed because it might have set the stage for another potential landmark Second Amendment decision by the high court.

The justices did not explain why they rejected the appeal, but the action does not end the possibility of a gun-rights case reaching the court this term. The Supreme Court is awaiting briefs in at least one other gun case, and several other Second Amendment cases are working their way to the Supreme Court.
