Two cases are pending this fall which offer the Supreme Court opportunities to delve into Second Amendment rights and the powers of Congress to regulate interstate commerce.
The Court's seminal decisions - establishing a constitutional right to have handguns in homes for self defense in Heller (2008) and applying the Second Amendment to states and localities in McDonald (2010) - reportedly have spawned more than 700 civil and criminal cases raising Second Amendment issues. Most of the cases that have gone to decision have upheld existing laws.
