In
McDonald v. Chicago, the Court ruled that the recently recognized 2d Amendment right of
individuals to keep and bear arms was applicable against state and local laws, not only against federal ones. This is the last of the 5 criminal law-related cases among the "Top Ten" highlights of last term.
The Court had previously decided, in
D.C. v. Heller (2008), that the 2d Amendment guarantees the firearm right to individuals, not simply to states to form and maintain organized militias. But because the Bill of Rights, ratified in the early years of the Republic, provides protections only against the federal government, the question remained whether such an
individual firearm right was sufficiently fundamental to be a protection against state and local government infringement as well. That is, speaking constitutionally, whether the firearm right is part of the "liberty" that is guaranteed against state governments and their subsidiaries by the 14th Amendment--one of the Amendments ratified after the Civil War.
In
McDonald, a 5-4 majority answered in the affirmative. State and local gun control laws throughout the country are now subject to close constitutional scrutiny. Undoubtedly, many of them will be casualties of the
McDonald ruling.
