Mcdonald V. City Of Chicago (2010)
U.S. Supreme Court decision in which the Court declared that the Second Amendment right to keep and bear arms applies to the states, so the Amendment's protections can be used to strike down state and local laws that limit gun rights. The Court's 5-4 ruling came after a constitutional challenge to Chicago-area laws that amount to a near-outright ban on the possession of handguns.
