A national gun industry group on Monday filed the latest lawsuit challenging Connecticut's new wide-ranging gun law, passed in the wake of the mass shooting at Sandy Hook Elementary School in Newtown.

The National Shooting Sports Foundation Inc., which is based in Newtown a few miles from Sandy Hook, claims the emergency legislation was illegally passed in April without proper public input, time for adequate review by members of the General Assembly, or a statement of facts explaining why lawmakers needed to bypass the usual legislative process.
