The Supreme Court on Monday agreed to hear a major Second Amendment dispute that could settle whether the Constitution protects a right to carry guns in public.

The decision, announced in an order, comes as President Joe Biden faces pressure from activists to take action to limit the availability of high-powered weapons amid outcries over mass shootings.

Those in favor of increased gun control measures have expressed concern that the nation’s top court, which has a 6-3 majority of Republican appointees, could expand the reach of the Second Amendment.

In two landmark cases handed down more than a decade ago, the Supreme Court held that the Second Amendment protects the individual right to carry a gun for self-defense inside the home. Last year, it declined to issue a substantial ruling in its first major Second Amendment case since.

In the case the court agreed to hear Monday, New York State Rifle & Pistol Association v. Keith Corlett, No. 20-843, individuals and a state organization are challenging a New York law that requires individuals to show “proper cause” in order to receive a permit for the open carry of a handgun.

Robert Nash and Brendan Koch, the individuals who brought the suit, both applied for licenses to carry handguns for self-defense and were denied. A district court reasoned that neither man had proper cause because neither faced “any special or unique danger to [their] life.”

A federal appeals court upheld the lower court’s decision not to grant the men licenses.
