The Supreme Court yesterday, as expected, granted certiorari to McDonald v. Chicago. In the 2007-2008 session of the Supreme Court, it decided District of Columbia v. Heller. In Heller the Supreme Court decided that the Second Amendment to the Constitution granted individuals a limited right to possess guns. Prior to Heller the general view was that the Second Amendment only grant a collective right to members of militias to possess guns.

Heller involved Federal law since it involved the District of Columbia. Therefore the Supreme Court did not decide whether the Second Amendment limited the ability of the states and local governments to control gun ownership. The Bill of Rights originally only protected citizens from the actions of the United States government. Over time the Supreme Court has gradually decided that the Fourteenth Amendment incorporated the various rights guaranteed by the Bill of Rights into the national law guaranteeing such rights against state and local limitations. However the Second Amendment has not been incorporated by the Supreme Court. This question will be decided in McDonald The Seventh Circuit took the traditional view following Nineteenth Century precedent in ruling that Heller is limited to Federal laws. On appeal the Supreme Court will rule whether it applies to state and local governments.

The traditional way to incorporate rights guaranteed by the bill of Rights is through the Due Process Clause of the Fourteenth Amendment, While Allen Gura, the attorney who argued Hellerr before the Supreme Court and who will argue McDonald will argue that the Supreme Court should use the Due Process Clause to incorporate the Second Amendment, alternatively he will argue that the Court should use the Privileges and Immunities Clause of the Fourteenth Amendment. Many modern scholars believe that the Privileges and Immunities Clause is the appropriate way to incorporate the rights guaranteed by the Bill of Rights. This will give us an opportunity to see whether the Supreme Court will adopt this theory.
