By Lawrence Rosenthal, Professor of Law, Chapman University School of Law. Professor Rosenthal filed an amicus brief on behalf of the U.S. Conference of Mayors in McDonald v. City of Chicago in support of Chicago.
In its 2008 decision in District of Columbia v. Heller, a closely divided Supreme Court, applying what the majority characterized as "the original understanding of the Second Amendment," invalidated D.C.'s prohibition on the possession of handguns. Relying on eighteenth-century sources, the Court defined the Second Amendment right to "keep and bear arms" as "the individual right to possess and carry weapons in case of confrontation," and held that a prohibition on handguns was unconstitutional. The Court cautioned, however, that the Second Amendment is only a limitation on the powers of Congress, and reserved decision on the question whether it also applied to state and local governments by virtue of the Fourteenth Amendment. The Court noted that its nineteenth-century decisions had refused to apply the Second Amendment to state and local laws, but added that these cases "did not engage in the sort of Fourteenth Amendment inquiry required by our later cases."
The Court will now confront the applicability of the Second Amendment to state and local laws in McDonald v. City of Chicago. At issue is the constitutionality of Chicago's handgun ban. Chicago and its amici rely on the approach to incorporation of the first eight amendments within the Fourteenth that the Court has taken for nearly a century - asking whether a particular right is "implicit in the concept of ordered liberty." Under this approach, many of the rights in the first eight amendments have been incorporated within the Fourteenth Amendment's Due Process Clause - but not all.

The widely anticipated Second Amendment case pending before the Supreme Court is creating strange bedfellows,
