Heller, 554 U.S. 570 (2008), is a landmark case in which the Supreme Court of the United States held, in a 5--4 decision, that the Second Amendment protects an individual's right to possess a firearm unconnected with service in a militia for traditionally lawful purposes, such as self - defense within the home, and that Washington, D.C.'s handgun ban and requirement that lawfully - owned rifles and shotguns be kept "unloaded and disassembled or bound by a trigger lock" violated this guarantee . Due to Washington, D.C.'s special status as a federal district, the decision did not address the question of whether the Second Amendment's protections are incorporated by the Due Process Clause of the Fourteenth Amendment against the states, which was addressed two years later by McDonald v.

Prior to this decision the Firearms Control Regulation Act of 1975 also restricted residents from owning handguns except for those registered prior to 1975 . </P>
