The following is a partial list of landmark court decisions in the United States. Landmark decisions establish a significant new legal principle or concept or otherwise that substantially changes the interpretation of existing law. Such a decision may settle the law in more than one way:

  • distinguishing a new principle that refines a prior principle, thus departing from prior practice without violating the rule of stare decisis;
  • establishing a "test" or a measurable standard that can be applied by courts in future decisions.

In the United States, landmark court decisions come most frequently from the Supreme Court. United States courts of appeals may also make such decisions, particularly if the Supreme Court chooses not to review the case or if it adopts the holding of the lower court, such as in Smith v. Collin. Although many cases from state supreme courts are significant in developing the law of that state, only a few are so revolutionary that they announce standards that many other state courts then choose to follow.

Other rights regarding counsel[edit]

  • Strickland v. Washington, 466 U.S. 668 (1984) To obtain relief due to ineffective assistance of counsel, a criminal defendant must show that counsel's performance fell below an objective standard of reasonableness and that counsel's deficient performance gives rise to a reasonable probability that, if counsel had performed adequately, the result of the proceeding would have been different.
  • Padilla v. Kentucky, 559 U.S. 356 (2010) Criminal defense attorneys are duty-bound to inform clients of the risk of deportation under three circumstances. First, where the law is unambiguous, attorneys must advise their criminal clients that deportation "will" result from a conviction. Second, where the immigration consequences of a conviction are unclear or uncertain, attorneys must advise that deportation "may" result. Finally, attorneys must give their clients some advice about deportation—counsel cannot remain silent about immigration consequences.

Right to remain silent[edit]

Competence[edit]

Detainment of terrorism suspects[edit]

Capital punishment[edit]

  • Furman v. Georgia, 408 U.S. 238 (1972) The arbitrary and inconsistent imposition of the death penalty violates the Eighth and Fourteenth Amendments and constitutes cruel and unusual punishment. This decision initiates a nationwide de facto moratorium on executions that lasts until the Supreme Court's decision in Gregg v. Georgia (1976).
  • Gregg v. Georgia, 428 U.S. 153 (1976) Georgia's new death penalty statute is constitutional because it adequately narrows the class of defendants eligible for the death penalty. This case and the next four cases were consolidated and decided simultaneously. By evaluating the new death penalty statutes that had been passed by the states, the Supreme Court ended the moratorium on executions that began with its decision in Furman v. Georgia (1972).
  • Proffitt v. Florida, 428 U.S. 242 (1976) Florida's new death penalty statute is constitutional because it requires the comparison of aggravating factors to mitigating factors in order to impose a death sentence.
  • Jurek v. Texas, 428 U.S. 262 (1976) Texas's new death penalty statute is constitutional because it uses a three-part test to determine if a death sentence should be imposed.
  • Woodson v. North Carolina, 428 U.S. 280 (1976) North Carolina's new death penalty statute is unconstitutional because it calls for a mandatory death sentence to be imposed.
  • Roberts v. Louisiana, 428 U.S. 325 (1976) Louisiana's new death penalty statute is unconstitutional because it calls for a mandatory death sentence for a large range of crimes.
  • Coker v. Georgia, 433 U.S. 584 (1977) A death sentence may not be imposed for the crime of rape.
  • Enmund v. Florida, 458 U.S. 782 (1982) A death sentence may not be imposed on offenders who are involved in a felony during which a murder is committed but who do not actually kill, attempt to kill, or intend that a killing take place.
  • Ford v. Wainwright, 477 U.S. 399 (1986) A death sentence may not be imposed on the insane.
  • McCleskey v. Kemp, 481 U.S. 279 (1987) Evidence of a "racially-disproportionate impact" in the application of the dealth penalty indicated by a comprehensive scientific study is not enough to invalidate an individual's death sentence without showing a "racially discriminatory purpose."
  • Breard v. Greene, 523 U.S. 371 (1998) The International Court of Justice does not have jurisdiction in capital punishment cases that involve foreign nationals.
  • Atkins v. Virginia, 536 U.S. 304 (2002) A death sentence may not be imposed on mentally retarded offenders, but the states can define what it means to be mentally retarded.
  • Roper v. Simmons, 543 U.S. 551 (2005) A death sentence may not be imposed on juvenile offenders.
  • Baze v. Rees, 553 U.S. 35 (2008) The three-drug cocktail used for performing executions by lethal injection in Kentucky (as well as virtually all of the states using lethal injection at the time) is constitutional under the Eighth Amendment.
  • Kennedy v. Louisiana, 554 U.S. 407 (2008) The death penalty is unconstitutional in all cases that do not involve homicide or crimes against the state such as treason.
  • Glossip v. Gross, 576 U.S. ___ (2015) The Eighth Amendment requires prisoners to show 1.) there is a known and available alternative method of execution and 2.) the challenged method of execution poses a demonstrated risk of severe pain, with the burden of proof resting on the prisoners, not the state.

Other criminal sentences[edit]

  • Apprendi v. New Jersey, 530 U.S. 466 (2000) Other than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury and proved beyond a reasonable doubt.
  • Blakely v. Washington, 542 U.S. 296 (2004) Mandatory state sentencing guidelines are the statutory maximum for purposes of applying the Apprendi rule.
  • Graham v. Florida, 560 U.S. 48 (2010) A sentence of life imprisonment without the possibility of parole may not be imposed on juvenile non-homicide offenders.
  • Miller v. Alabama, 567 U.S. 460 (2012) A sentence of life imprisonment without the possibility of parole may not be a mandatory sentence for juvenile offenders.

Federalism[edit]

First Amendment rights[edit]

Freedom of speech and of the press[edit]

Freedom of religion[edit]

Freedom of association[edit]

Freedom of petition[edit]

Second Amendment rights[edit]

Third Amendment rights[edit]

  • Engblom v. Carey, 677 F.2d 957 (2d Cir. 1982) While not a Supreme Court case, this is the only case to have been heard by a federal appeals court based on Third Amendment claims. The ruling is notable for three important findings regarding the Third Amendment: 1) members of the National Guard are "soldiers" within the context of the Third Amendment; 2) the Third Amendment is incorporated by the Fourteenth Amendment; and 3) the "house[s]" which are protected by the Third Amendment are not limited solely to those arising out of fee simple ownership but extend to those recognized and permitted by society as founded on lawful occupation or possession with a legal right to exclude others.
