National Association for Gun Rights v. City of Naperville, Illinois

Issue: (1) Whether the state of Illinois"s ban of certain handguns is constitutional in light of the holding in District of Columbia v. Heller that handgun bans are categorically unconstitutional; (2) whether the "in common use" test announced in Heller is hopelessly circular and therefore unworkable; and (3) whether the government can ban the sale, purchase, and possession of certain semi-automatic firearms and firearm magazines that are possessed by millions of law-abiding Americans for lawful purposes when there is no analogous Founding-era regulation.
