A constitutional challenge to Massachusetts restrictions on certain semi-automatic firearms and large-capacity magazines reached the U.S. Supreme Court on Monday, marking the fourth gun-related petition that asks the high court for regulatory guidance in the new term.

The Massachusetts petition—in the case Worman v. Healey—was filed on behalf of a group of firearm owners, dealers and an advocacy organization. John Parker Sweeney, a Bradley Arant Boult Cummings partner in Washington, is lead counsel for the challengers.
