In McDonald v. City of Chicago, a 5-4 majority of the Court overturned the Seventh Circuit and held that a Chicago gun control law violated the Second Amendment's guarantee of the right to bear arms. Building on a 2008 decision in District of Columbia v. Heller, which placed limits on what the federal government may do to regulate guns, the Court held that the right to bear arms is a fundamental right that limits state and local law, as well as federal law.
"In its decision today in McDonald v. Chicago, the Supreme Court, following its decision in Heller, ruled that the Second Amendment applies equally to the states in addition to the federal government. At the heart of this case is the fundamental right to protect oneself in the home. Today's opinion will ensure that any firearm regulation must be measured against the right the Second Amendment secures.
"I support the Court's decision and believe that today's opinion strengthens the protections of our Bill of Rights. Although state and local governments will now have to proceed more carefully when enacting firearms regulations, it will be in respect of a right that belongs to all Americans. "
