New paperwork has been filed in the lawsuit by some Sandy Hook families against Remington Arms.  A motion was filed this week by Attorney Josh Koskoff, who represents the families of nine children and adults killed and a teacher who survived. 

The motion claims that the appeal to dismiss the suit by Bushmaster Firearms' parent company should be denied because it is designed to preclude discovery that both sides have done to prepare for the trail, which has been scheduled. 

The gun company's lawyers argue the lawsuit is barred by a 2005 federal law that shields gun manufacturers from most lawsuits over criminal use of their products. 

The lawsuit says Remington knew or should have known the AR-15-style rifle was dangerous and meant for the military, but sold it to the public anyway and should be held accountable.
