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.
Lemon v. Kurtzman Lemon v. Kurtzman, 403 U.S. 602 (1971), was a case argued before the Supreme Court of the United States. The court ruled in an 8–1 decision that Pennsylvania's Nonpublic Elementary and Secondary Education Act (represented through David Kurtzman) from 1968 was unconstitutional, violating the Establishment Clause of the First Amendment. The act allowed the Superintendent of Public Schools to reimburse private schools (mostly Catholic) for the salaries of teachers who taught in these private schools, from public textbooks and with public instructional materials. The decision also upheld a decision of the First Circuit, which had struck down the Rhode Island Salary Supplement Act providing state funds to supplement salaries at private elementary schools by 15%. As in Pennsylvania, most of these funds were spent on Catholic schools.
