Gun law challenges in Delaware and Maryland are decided by the Supreme Court.

On Monday, the Supreme Court rejected appeals concerning gun laws in Delaware and Maryland.

The gun enthusiasts and firearm advocacy groups in Delaware were unable to have their appeal heard by the justices, who upheld the state's ban on assault-style rifles and large-capacity ammunition magazines, following a lower court's refusal to grant a preliminary injunction.

In 2022, Delaware passed gun safety laws that prohibit the sale and possession of certain semi-automatic long guns, including the AR-15 and AK47, except for those who owned them before the law was enacted, under specific conditions, reports Reuters.

The Supreme Court, with a 6-3 conservative majority, refused to hear a case challenging Maryland's handgun licensing requirements, which mandate safety training, fingerprinting, and a background check prior to purchasing a handgun.

The Second Amendment is being violated by the handgun law, according to the challengers, because it makes it excessively difficult for individuals to obtain firearms.

The 2012 Sandy Hook Elementary School shooting in Connecticut led to the passing of the law.

The three-judge appeals court panel overturned the law following a landmark 2022 Supreme Court ruling that broadened gun rights and mandated that firearm laws be grounded in the country's historical traditions. However, the full 4th U.S. Circuit Court of Appeals later reinstated the law after the majority concluded that it fell within the scope of historic firearm regulations.
