HARTFORD, Conn. (AP) — The Connecticut Supreme Court is set to hear arguments on whether gun maker Remington Arms should be held liable for the 2012 Newtown school massacre.

A hearing is scheduled for Tuesday in an appeal by a survivor and relatives of nine people killed in the shooting.

They're trying to sue Remington Arms, the North Carolina company that made the Bushmaster AR-15-style rifle used to kill 20 first-graders and six educators at Sandy Hook Elementary School. Gunman Adam Lanza's mother legally purchased the rifle.

A lower court judge dismissed the lawsuit, saying federal law shields gun makers from most lawsuits over criminal use of their products.

The company denies the lawsuit's allegations that it violated state law by selling such a dangerous weapon to the public.
