The Supreme Court declined Monday to hear arguments in a pair of significant Second Amendment challenges involving certain semi-automatic weapons and high-capacity magazines, a move that leaves both of those laws in place.

The case from Maryland was the court’s latest opportunity to apply its recently announced history-based test for assessing the constitutionality of gun control laws.

WASHINGTON — A closely divided Supreme Court refused Monday to hear a 2nd Amendment challenge to the bans on semiautomatic rifles in Maryland, California and eight other blue states.
