A federal appeals court on Monday upheld the core provisions of two gun control laws passed in New York and Connecticut after the 2012 mass murder at Sandy Hook Elementary School that banned possession of semiautomatic assault weapons.
The 2nd U.S. Circuit Court of Appeals in New York upheld the bans on semiautomatic weapons and large-capacity magazines, but struck down a New York provision regulating load limits and a Connecticut prohibition on the non-semiautomatic Remington 7615.
New York and Connecticut's gun control measures, among the strictest in the nation, were signed into law after a gunman killed 26 children and staff at the school in Newtown, Connecticut, in December 2012.

The Newtown shooting revived a national debate on gun control. At the time, President Barack Obama launched an aggressive gun control push but his efforts largely failed in Congress.
The appeals court, in upholding the provisions, ruled against coalitions that included firearms dealers, sports shooters and gun owners who claimed the mandates infringed on their Second Amendment rights to possess firearms in self-defense.
