Two gunmakers facing a liability lawsuit in the wake of the Sandy Hook Elementary School massacre are asking the Connecticut Supreme Court to toss out the case, largely on the same grounds they used to win a dismissal last year.

Gun manufacturers Remington and Bushmaster argued several of the victims’ families have no standing under the negligent entrustment clause of the Connecticut Unfair Trade Practices Act or a separate federal law, which broadly protects manufacturers and distributors from liability suits. Remington owns Bushmaster, which made the AR-15 rifle used by Adam Lanza in the 2012 massacre.
