Which was decided first, Graham v. Florida or District of Columbia v. Heller?
District of Columbia v. Heller District of Columbia v. 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. City of Chicago" (2010) in which it was found that they are. It was the first Supreme Court case to decide whether the Second Amendment protects an individual right to keep and bear arms for self-defense.
Barrett v. United States Barrett v. United States, 169 U.S. 218 (1898), was a case in which the Supreme Court of the United States held that South Carolina had never effectively been subdivided into separate judicial districts. Therefore, it was held, a criminal defendant allegedly tried in one district for a crime committed in the other had in fact been permissibly been tried in a separate division of a single district.
