미국 정부를 이해하는데 가장 중요한 판결이다.

• Marbury v. Madison (1803)
• McCulloch v. Maryland (1819)
• Gibbons v. Ogden (1824)
• Dred Scott v. Sandford (1857)
• Schenck v. United States (1919)
• Brown v. Board of Education (1954)
• Gideon v. Wainwright (1963)
• Miranda v. Arizona (1966)

Landmark court decisions in the United States change the interpretation of existing law. Such a decision may settle the law in more than one way:

• establishing a significant new legal principle or concept;
• overturning prior precedent based on its negative effects or flaws in its reasoning;
• 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.

Individual rights

Discrimination based on race and ethnicity

• Dred Scott v. Sandford, 틀:Ussc People of African descent that are slaves or were slaves and subsequently freed, along with their descendants, cannot be United States citizens. Consequently, they cannot sue in federal court. Slavery cannot be prohibited in U.S. territories before they are admitted to the Union as doing so would violate the Due Process Clause of the Fifth Amendment. After the Civil War, this decision was voided by the Thirteenth and Fourteenth Amendments to the Constitution.
• Strauder v. West Virginia, 틀:Ussc The exclusion of individuals from juries solely because of their race is a violation of the Equal Protection Clause. This was the first time that the Supreme Court reversed a state criminal conviction due to a violation of a constitutional provision concerning criminal procedure.
• Yick Wo v. Hopkins, 틀:Ussc Racially discriminatory application of a racially neutral statute violates the Equal Protection Clause of the Fourteenth Amendment.
• Plessy v. Ferguson, 틀:Ussc Segregated facilities for blacks and whites are constitutional under the doctrine of separate but equal. As long as the separate facilities are equal in quality, then such separation is not unconstitutional. (de facto overruled by Brown v. Board of Education (1954))
• Missouri ex rel. Gaines v. Canada, 틀:Ussc States with racially segregated educational systems cannot satisfy the "separate but equal" provision of Plessy merely by offering to pay for black students to be educated at an out-of-state institution; they must offer those opportunities in-state.
• Smith v. Allwright, 틀:Ussc Primary elections must be open to voters of all races.
• Steele v. Louisville & Nashville Railway Co., 틀:Ussc Imposed duty of fair representation on labor unions, requiring that they represent all members of their bargaining unit equally, without regard to race or union membership (later understood to include other protected categories).
• Korematsu v. United States, 틀:Ussc President Franklin D. Roosevelt's Executive Order 9066 is constitutional; therefore, American citizens of Japanese descent can be interned and deprived of their basic constitutional rights. This case featured the first application of strict scrutiny to racial discrimination by the government. (Potentially overruled by Trump v. Hawaii (2018))
• Morgan v. Virginia, 틀:Ussc A Virginia law that enforces segregation on interstate buses is unconstitutional.
• Shelley v. Kraemer, 틀:Ussc Courts may not enforce racial covenants on real estate.

• Hernandez v. Texas, 틀:Ussc The equal protection of the laws guaranteed by the Fourteenth Amendment covers any racial, national, and ethnic groups of the United States against whom discrimination can be proved.
• Brown v. Board of Education, 틀:Ussc Segregated schools in the states are unconstitutional because they violate the Equal Protection Clause of the Fourteenth Amendment. The Court found that the separate but equal doctrine adopted in Plessy "has no place in the field of public education".
• Bolling v. Sharpe, 틀:Ussc Segregated schools in the District of Columbia violate the Equal Protection Clause as incorporated against the federal government by the Due Process Clause of the Fifth Amendment.
• Sarah Keys v. Carolina Coach Company, 64 MCC 769 (1955) According to the Interstate Commerce Commission, the non-discrimination language of the Interstate Commerce Act of 1887 bans racial segregation on buses traveling across state lines. The Supreme Court later adopted and expanded this decision in Boynton v. Virginia (1960).
• Browder v. Gayle, 142 F.Supp. 707 (M.D. Ala. 1956) Bus segregation is unconstitutional under the Equal Protection Clause.
• Gomillion v. Lightfoot, 틀:Ussc Electoral district boundaries drawn only to disenfranchise blacks violate the Fifteenth Amendment.

• Garner v. Louisiana, 틀:Ussc Peaceful sit-in demonstrators protesting segregationist policies cannot be arrested under a state's "disturbing the peace" laws.
• Heart of Atlanta Motel, Inc. v. United States, 틀:Ussc The Commerce Clause gives Congress power to force private businesses to abide by Title II of the Civil Rights Act of 1964, which prohibits discrimination in public accommodations.
• Loving v. Virginia, 틀:Ussc Laws that prohibit interracial marriage (anti-miscegenation laws) are unconstitutional.
• Swann v. Charlotte-Mecklenburg Board of Education, 틀:Ussc The busing of students to promote racial integration in public schools is constitutional.
• Gates v. Collier, 501 F.2d 1291 (5th Cir. 1974) This decision brought an end to the trusty system and flagrant inmate abuse at the Mississippi State Penitentiary in Parchman, Mississippi. It was the first body of law developed in the Fifth Circuit that abolished racial segregation in prisons and held that a variety of forms of corporal punishment against prisoners is considered cruel and unusual punishment in violation of the Eighth Amendment.
• Regents of the University of California v. Bakke, 틀:Ussc Racial quotas in educational institutions violate the Equal Protection Clause, but a more narrowly tailored use of race in admission decisions may be permissible.
• Batson v. Kentucky, 틀:Ussc Prosecutors may not use peremptory challenges to dismiss jurors based on their race.
• Adarand Constructors, Inc. v. Peña, 틀:Ussc Race-based discrimination, including discrimination in favor of minorities (affirmative action), must pass strict scrutiny.
• Grutter v. Bollinger, 틀:Ussc A narrowly tailored use of race in student admission decisions may be permissible under the Equal Protection Clause because a diverse student body is beneficial to all students. This was hinted at in Regents v. Bakke (1978).
• Schuette v. Coalition to Defend Affirmative Action, 틀:Ussc A Michigan state constitutional amendment that bans affirmative action does not violate the Equal Protection Clause.

Discrimination based on sex

• Muller v. Oregon, 틀:Ussc Oregon's restrictions on the working hours of women are constitutional under the Fourteenth Amendment because they are justified by the strong state interest in protecting women's health.
• Glasser v. United States, 틀:Ussc The exclusion of women from the jury pool, other than members of the League of Women Voters who have attended a jury training class, violates the fair-cross section requirement of the Impartial Jury Clause of the Sixth Amendment. Noteworthy for being the first majority opinion of the Court to use the phrase "cross-section of the community" and the first jury discrimination case to invoke the Sixth Amendment rather than Equal Protection Clause of the Fourteenth Amendment.
• Phillips v. Martin Marietta Corp., 틀:Ussc An employer may not, in the absence of business necessity, refuse to hire women with preschool-age children while hiring men with such children.
• Reed v. Reed, 틀:Ussc Administrators of estates cannot be named in a way that discriminates on the basis of sex.
• Frontiero v. Richardson, 틀:Ussc Sex-based discriminations are inherently suspect. A statute that gives benefits to the spouses of male members of the uniformed services, but not to the spouses of female members, (on the assumption that only the former are dependent) is unconstitutional.
• Taylor v. Louisiana, 틀:Ussc Systematic exclusion of women from jury service on the basis of having to register for jury duty violates a criminal defendant's Sixth and Fourteenth Amendment rights.
• Craig v. Boren, 틀:Ussc Setting different minimum ages for females (18) and males (21) to be allowed to buy beer is unconstitutional sex-based discrimination contrary to the Equal Protection Clause of the Fourteenth Amendment.
• Mississippi University for Women v. Hogan, 틀:Ussc The single-sex admissions policy of the Mississippi University for Women's School of Nursing violated the Equal Protection Clause of the Fourteenth Amendment.
• Price Waterhouse v. Hopkins, 틀:Ussc Discrimination against an employee on the basis of sex stereotyping - that is, a person's nonconformity to social or other expectations of that person's gender - constitutes impermissible sex discrimination, in violation of Title VII of the Civil Rights Act of 1964. The employer bears the burden of proving that the adverse employment action would have been the same if sex discrimination had not occurred.
• J.E.B. v. Alabama ex rel. T.B., 틀:Ussc Prosecutors may not use peremptory challenges to dismiss jurors based on their sex.
• United States v. Virginia, 틀:Ussc Sex-based "separate but equal" military training facilities violate the Equal Protection Clause.
• Oncale v. Sundowner Offshore Services, 틀:Ussc The protection of Title VII of the Civil Rights Act of 1964 against workplace discrimination "because of... sex" applied to harassment in the workplace between members of the same sex.
• Burlington Northern & Santa Fe Railway Co. v. White, 틀:Ussc The anti-retaliation provision under Title VII of the Civil Rights Act of 1964 does not confine the actions and harms it forbids to those that are related to employment or occur at the workplace.

Discrimination based on sexual orientation or gender identity

• One, Inc. v. Olesen, 틀:Ussc (per curiam) Pro-homosexual writing is not per se obscene. This was the first Supreme Court ruling to deal with homosexuality and the first to address free speech rights with respect to homosexuality.
• Bowers v. Hardwick, 틀:Ussc A Georgia law that criminalizes certain acts of private sexual conduct between homosexual persons does not violate the Fourteenth Amendment (overruled by Lawrence v. Texas (2003)).
• Romer v. Evans, 틀:Ussc A Colorado state constitutional amendment that prevents homosexuals and bisexuals from being able to obtain protections under the law is a violation of the Equal Protection Clause of the Fourteenth Amendment.
• Lawrence v. Texas, 틀:Ussc A Texas law that criminalizes consensual same-sex sexual conduct furthers no legitimate state interest and violates homosexuals' right to privacy under the Due Process Clause of the Fourteenth Amendment. This decision invalidates all of the remaining sodomy laws in the United States.
• Goodridge v. Department of Public Health, 440 Mass. 309 (2003) The denial of marriage licenses to same-sex couples violates provisions of the state constitution guaranteeing individual liberty and equality and is not rationally related to a legitimate state interest. This was the first state court decision in which same-sex couples won the right to marry.
• United States v. Windsor, 틀:Ussc Section 3 of the Defense of Marriage Act, which defines—for federal law purposes—the terms "marriage" and "spouse" to apply only to marriages between one man and one woman, is a deprivation of the equal liberty of the person protected by the Due Process Clause of the Fifth Amendment. The federal government must recognize same-sex marriages that have been approved by the states.
• SmithKline Beecham Corporation v. Abbott Laboratories, 740 F.3d 471 (9th Cir. 2014) The Equal Protection Clause prohibits peremptory strikes to dismiss jurors based on their sexual orientation. This was the first holding by a federal appeals court that classifications based on sexual orientation must be subjected to heightened scrutiny.
• Obergefell v. Hodges, 틀:Ussc The Fourteenth Amendment requires a state to license a marriage between two people of the same sex with all the accompanying rights and responsibilities and to recognize a marriage between two people of the same sex when their marriage was lawfully licensed and performed out-of-state.
• Bostock v. Clayton County, 틀:Ussc, R.G. & G.R. Harris Funeral Homes Inc. v. Equal Employment Opportunity Commission, 틀:Ussc, and Altitude Express, Inc. v. Zarda, 틀:Ussc, Title VII of the Civil Rights Act of 1964 protects employees against discrimination due to their sexual orientation or gender identity. The Supreme Court ruled under Bostock but the ruling covered all three cases.

Power of Congress to enforce civil rights

• Civil Rights Cases, 틀:Ussc Neither the Thirteenth nor the Fourteenth Amendment empower Congress to safeguard blacks against the actions of private individuals.
• Heart of Atlanta Motel, Inc. v. United States, 틀:Ussc The Civil Rights Act of 1964 applies to places of public accommodation patronized by interstate travelers by reason of the Commerce Clause.
• Katzenbach v. McClung, 틀:Ussc The power of Congress to regulate interstate commerce extends to a restaurant that is not patronized by interstate travelers but which serves food that has moved in interstate commerce. This ruling makes the Civil Rights Act of 1964 apply to virtually all businesses.
• South Carolina v. Katzenbach, 틀:Ussc The Voting Rights Act of 1965 is a valid exercise of Congress's power under Section 2 of the Fifteenth Amendment.
• Katzenbach v. Morgan, 틀:Ussc Congress may enact laws stemming from Section 5 of the Fourteenth Amendment that increase the rights of citizens beyond what the judiciary has recognized.
• Jones v. Alfred H. Mayer Co., 틀:Ussc Section 1982, part of the Civil Rights Act of 1866, is constitutional under the Thirteenth Amendment and prohibits all racial discrimination in the sale or rental of property.
• City of Boerne v. Flores, 틀:Ussc Section 5 of the Fourteenth Amendment does not permit Congress to substantially increase the scope of the rights determined by the judiciary. Congress may only enact remedial or preventative measures that are consistent with the Fourteenth Amendment interpretations of the Supreme Court.
• Shelby County v. Holder, 틀:Ussc Section 4(b) of the Voting Rights Act of 1965, which contains the coverage formula that determines which state and local jurisdictions are subjected to federal preclearance from the Department of Justice before implementing any changes to their voting laws or practices based on their histories of racial discrimination in voting, is unconstitutional because it no longer reflects current societal conditions.

Immunity from civil rights violations

• Monroe v. Pape, 틀:Ussc While municipalities can not be liable under the Civil Rights Act of 1871, individuals acting “under color of law” can be sued for damages for denying the constitutional rights of individuals. (overruled in Monell v. Department of Social Services of the City of New York, 436 U.S. 658 (1978) (in part))
• Pierson v. Ray, 틀:Ussc Police officers are protected from being sued for civil rights violations under Section 1983 by the doctrine of qualified immunity.
• Stump v. Sparkman, 틀:Ussc A judge will not be deprived of judicial immunity because the action he took was in error, was done maliciously, or was in excess of his authority. He will be subject to liability only when he has acted in the clear absence of all jurisdiction.
• Monell v. Department of Social Services of the City of New York, 틀:Ussc Municipalities can be held liable for violations of Constitutional rights through 42 U.S.C. § 1983 actions. §1983 claims against municipal entities must be based on implementation of a policy or custom.
• Harris v. Harvey, 605 F.2d 330 (7th Cir. 1979) The Seventh Circuit established that a judge engaging in acts of public defamation inspired by racial prejudice is not protected by judicial immunity and therefore a civil lawsuit against a judge can be brought under the Civil Rights Act (42 U.S.C. § 1983).
• Will v. Michigan Department of State Police, 틀:Ussc Neither States nor state officials acting in their official capacities are "persons" within the meaning of 42 U.S.C. § 1983 when being sued for monetary damages.

Birth control and abortion

• Griswold v. Connecticut, 틀:Ussc A Connecticut law that criminalizes the use of contraception by married couples is unconstitutional because all Americans have a constitutionally protected right to privacy.
• Eisenstadt v. Baird, 틀:Ussc A Massachusetts law that criminalizes the use of contraception by unmarried couples violates the right to privacy established in Griswold as well as the Equal Protection Clause of the Fourteenth Amendment.
• Roe v. Wade, 틀:Ussc Laws that restrict a woman's ability to have an abortion prior to viability are unconstitutional. Most restrictions during the first trimester are prohibited, and only health-related restrictions are permitted during the second trimester. The decision was partially overruled by Planned Parenthood v. Casey in 1992 and fully overruled by Dobbs v. Jackson Women's Health Organization in 2022.
• Carey v. Population Services International, 틀:Ussc Laws that restrict the sale, distribution, and advertisement of contraceptives to both adults and minors are unconstitutional.
• Planned Parenthood v. Casey, 틀:Ussc A woman is still able to have an abortion before viability, but several restrictions are now permitted during the first trimester. The strict trimester framework of Roe is discarded and replaced with the more flexible "undue burden" test. The decision was overruled by Dobbs v. Jackson Women's Health Organization in 2022.
• Stenberg v. Carhart, 틀:Ussc Laws that ban partial-birth abortion are unconstitutional if they do not make an exception for the woman's health or if they cannot be reasonably construed to apply only to the partial-birth abortion procedure and not to other abortion methods.
• Gonzales v. Carhart, 틀:Ussc The Partial-Birth Abortion Ban Act of 2003 is constitutional because it is less ambiguous than the law that was struck down in Stenberg. It is not vague or overbroad, and it does not impose an undue burden on a woman's right to choose to have an abortion.
• Burwell v. Hobby Lobby Stores, Inc., 틀:Ussc Closely held, for-profit corporations have free exercise rights under the Religious Freedom Restoration Act of 1993. As applied to such corporations, the requirement of the Patient Protection and Affordable Care Act that employers provide their female employees with no-cost access to contraception violates the Religious Freedom Restoration Act.
• Whole Woman's Health v. Hellerstedt, 틀:Ussc A Texas law that requires abortion providers to have admitting privileges at a hospital within 30 miles and to meet the same standards as ambulatory surgical centers places a substantial obstacle in the path of a woman seeking a pre-viability abortion, constitutes an undue burden on abortion access, and thus violates the Constitution. Overruled by Dobbs v. Jackson Women's Health Organization in 2022.
• Dobbs v. Jackson Women's Health Organization, (2022) The constitution does not provide for abortion protections, overruling both Roe v. Wade and Planned Parenthood v. Casey.

End of life

• Cruzan v. Director, Missouri Department of Health, 틀:Ussc When a family has requested the termination of life-sustaining treatments for their vegetative relative, the state may constitutionally oppose this request if there is a lack of evidence of a clear earlier wish by said relative.
• Washington v. Glucksberg, 틀:Ussc Washington's prohibition on assisted suicide is constitutional.
• Vacco v. Quill, 틀:Ussc New York's prohibition on assisted suicide does not violate the Equal Protection Clause.

Citizenship

• United States v. Wong Kim Ark, 틀:Ussc With only a few narrow exceptions, every person born in the United States acquires United States citizenship at birth via the Citizenship Clause of the Fourteenth Amendment.
• Afroyim v. Rusk, 틀:Ussc The right of citizenship is protected by the Citizenship Clause of the Fourteenth Amendment. Congress has no power under the Constitution to revoke a person's United States citizenship unless the person voluntarily relinquishes it.

Freedom of movement

• Edwards v. California, 틀:Ussc A state cannot prohibit indigent people from moving into it.

• Aptheker v. Secretary of State, 틀:Ussc Section 6 of the Subversive Activities Control Act of 1950, which makes it a crime for any member of a communist organization to attempt to use or obtain a passport, is an unconstitutional abridgment of the right to travel.
• United States v. Guest, 틀:Ussc There is a constitutional right to travel from state to state, and the protections of the Fourteenth Amendment extend to citizens who suffer deprivations of their rights at the hands of a private conspiracy where there is state participation in the conspiracy, no matter how minimal.
• Shapiro v. Thompson, 틀:Ussc The fundamental right to travel and the Equal Protection Clause forbid a state from reserving welfare benefits only for persons that have resided in the state for at least one year.
• Saenz v. Roe, 틀:Ussc A California law that limits new residents' benefits for the first year they live in the state is an unconstitutional violation of their right to travel.

Restrictions on involuntary commitment

• Jackson v. Indiana, 틀:Ussc A state violates due process by involuntarily committing a criminal defendant for an indefinite period of time solely on the basis of his or her permanent incompetency to stand trial on the charges filed against him or her.
• O'Connor v. Donaldson, 틀:Ussc A state cannot constitutionally confine a non-dangerous individual who is capable of surviving safely in freedom by themselves or with the help of willing and responsible family members or friends.

Public health and safety

• Compagnie Francaise de Navigation a Vapeur v. Louisiana Board of Health, 틀:Ussc A state's police power to enforce quarantine laws extends to restricting the movements of uninfected individuals.
• Jacobson v. Massachusetts, 틀:Ussc Individual liberty is not absolute, and a state's police power must be held to embrace at least such reasonable regulations established directly by legislative enactment to protect public health and safety, which extends to compulsory vaccination laws.
• Zucht v. King, 틀:Ussc School districts can constitutionally exclude unvaccinated students.
• Prince v. Massachusetts, 틀:Ussc States have broad authority to regulate the actions and treatment of children. Parental authority is not absolute and can be permissibly restricted if doing so is in the interests of a child's welfare. While children share many of the rights of adults, they face different potential harms from similar activities. Compulsory vaccination is an example of a fundamental police power.
• Buck v. Bell 틀:Ussc State statutes permitting compulsory sterilization of the unfit, including the intellectually disabled, "for the protection and health of the state" did not violate the Due Process Clause of the Fourteenth Amendment. (partially overruled by Skinner v. Oklahoma (1942) and fully by the Americans with Disabilities Act of 1990)

Other areas

• Corfield v. Coryell, 6 Fed. Cas. 546 (C.C.E.D. Pa. 1823) Some of the rights protected by the Privileges and Immunities Clause include the freedom of movement through the states, the right of access to the courts, the right to purchase and hold property, an exemption from higher taxes than those paid by state residents, and the right to vote. This case was decided by Supreme Court Justice Bushrod Washington while riding circuit in the Circuit Court for the Eastern District of Pennsylvania. It is notable for Washington asserting the existence of cognizable rights within the ambit of the Privileges and Immunities Clause that are nowhere within the Constitution's text.
• Ex parte Milligan, 틀:Ussc Trying citizens in military courts is unconstitutional when civilian courts are still operating. Trial by military tribunal is constitutional only when there is no power left but the military, and the military may validly try criminals only as long as is absolutely necessary.

• Katz v. United States, 틀:Ussc The Fourth Amendment's ban on unreasonable searches and seizures applies to all places where an individual has a "reasonable expectation of privacy."

• Bivens v. Six Unknown Named Agents, 틀:Ussc Individuals may sue federal government officials who have violated their Fourth Amendment rights even though such a suit is not authorized by law. The existence of a remedy for the violation is implied from the importance of the right that is violated.
• United States v. United States District Court for the Eastern District of Michigan, 틀:Ussc Government officials must obtain a warrant before beginning electronic surveillance even if domestic security issues are involved. The "inherent vagueness of the domestic security concept" and the potential for abusing it to quell political dissent make the Fourth Amendment's protections especially important when the government spies on its own citizens.
• Illinois v. Gates, 틀:Ussc The totality of the circumstances, rather than a rigid test, must be used in finding probable cause under the Fourth Amendment.
• New Jersey v. T. L. O., 틀:Ussc The Fourth Amendment's ban on unreasonable searches applies to those conducted by public school officials as well as those conducted by law enforcement personnel, but public school officials can use the less strict standard of reasonable suspicion instead of probable cause.

Right to counsel

• Powell v. Alabama, 틀:Ussc Under the Due Process Clause of the 14th Amendment, a state must inform illiterate defendants charged with a capital crime that they have a right to be represented by counsel and must appoint counsel for defendants who cannot afford to hire a lawyer and give counsel adequate time to prepare for trial.

• Michigan v. Jackson, 틀:Ussc If a police interrogation begins after a defendant asserts his or her right to counsel at an arraignment or similar proceeding, then any waiver of that right for that police-initiated interrogation is invalid (overruled by Montejo v. Louisiana (2009)).
• Montejo v. Louisiana, 틀:Ussc A defendant may waive his or her right to counsel during a police interrogation even if the interrogation begins after the defendant's assertion of his or her right to counsel at an arraignment or similar proceeding.

Other rights regarding counsel

• Strickland v. Washington, 틀:Ussc 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.

First, where the law is unambiguous, attorneys must advise their criminal clients that deportation "will" result from a conviction.

Finally, attorneys must give their clients some advice about deportation—counsel cannot remain silent about immigration consequences.

Right to remain silent

• Berghuis v. Thompkins, 틀:Ussc The right to remain silent does not exist unless a suspect invokes it unambiguously.
• Salinas v. Texas, 틀:Ussc The Fifth Amendment's protection against self-incrimination does not protect an individual's refusal to answer questions asked by law enforcement before he or she has been arrested or given the Miranda warning.

• Gregg v. Georgia, 틀:Ussc Georgia's new death penalty statute is constitutional because it adequately narrows the class of defendants eligible for the death penalty.

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, 틀:Ussc 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.

• Bucklew v. Precythe, 587 U.S. ___ (2019), Baze v. Rees and Glossip v. Gross govern all Eighth Amendment challenges alleging that a method of execution inflicts unconstitutionally cruel pain.

Brewer, 틀:Ussc The Supreme Court extended Fourteenth Amendment due process protection to the parole revocation process, hold that the due process clause of the Fourteenth Amendment requires a "neutral and detached" hearing body such as a parole board to give an evidentiary hearing prior to revoking the parole of a defendant and spelled out the minimum due process requirements for the revocation hearing.
• Gagnon v. Scarpelli, 틀:Ussc The Supreme Court issued a substantive ruling regarding the rights of individuals in violation of a probation or parole sentence.

• Wolff v. McDonnell, 틀:Ussc In administrative proceedings regarding discipline, prisoners retain some of their due process rights. When a prison disciplinary hearing might result in the loss of good-time credits, due process requires that the prison notify the prisoner in advance of the hearing, afford him an opportunity to call witnesses and present documentary evidence in his defense, and furnish him with a written statement of the evidence relied on and the reason for the disciplinary action.
• Bearden v. Georgia, 틀:Ussc A sentencing court cannot properly revoke a defendant's probation for failure to pay a fine and make restitution, absent evidence and findings that he was somehow responsible for the failure or that alternative forms of punishment were inadequate to meet the State's interest in punishment and deterrence.

Election-related cases

Gore, 틀:Ussc The recount of ballots in Florida during the 2000 presidential election violated the Equal Protection Clause because different standards of counting were used in the counties that were subjected to the recount.

• Pollock v. Farmers' Loan & Trust Co., 틀:Ussc Income taxes on interest, dividends, and rents are, in effect, direct taxes that must be apportioned among the states according to their populations.

• National Labor Relations Board v. Jones & Laughlin Steel Corporation, 틀:Ussc The National Labor Relations Act and, by extension, the National Labor Relations Board are constitutional because the Commerce Clause applies to labor relations.

Also, a local commercial activity that is considered in isolation may still constitute interstate commerce if that activity has a "close and substantial relationship" to interstate commerce.
• Steward Machine Company v. Davis, 틀:Ussc The federal government is permitted to impose a tax even if the goal of the tax is not just the collection of revenue.

• South Dakota v. Dole, 틀:Ussc Congress may attach reasonable conditions to funds disbursed to the states without violating the Tenth Amendment.
• United States v. Lopez, 틀:Ussc The Gun-Free School Zones Act of 1990 is unconstitutional. The Commerce Clause of the Constitution does not give Congress the power to prohibit the mere possession of a gun near a school because gun possession by itself is not an economic activity that affects interstate commerce even indirectly. Notable because it was the first time since the New Deal that the Supreme Court invalidated a law which was passed by Congress ostensibly permissible under the Commerce Clause.
• U.S. Term Limits, Inc. v. Thornton, 틀:Ussc The states cannot create qualifications for prospective members of Congress that are stricter than those specified in the Constitution. This decision invalidates provisions that had imposed term limits on members of Congress in 23 states.

• Bond v. United States (2011), 틀:Ussc An individual litigant has standing to challenge a federal statute on grounds of federalism.

• National Federation of Independent Business v. Sebelius, 틀:Ussc The Patient Protection and Affordable Care Act's expansion of Medicaid is unconstitutional as-written—it is unduly coercive to force the states to choose between participating in the expansion or forgoing all Medicaid funds. In addition, the individual health insurance mandate is constitutional by virtue of the Taxing and Spending Clause (though not by the Commerce Clause or the Necessary and Proper Clause).
• Murphy v. National Collegiate Athletic Association, 틀:Ussc The Professional and Amateur Sports Protection Act of 1992 violates the Tenth Amendment because it prohibits the states from passing laws that authorize and regulate sports betting.

Native American law

• Johnson v. M'Intosh, 틀:Ussc Private citizens cannot purchase lands from Native Americans.
• Worcester v. Georgia, 틀:Ussc The Supreme Court laid out the relationship between tribes and the state and federal governments.

• Ex parte Crow Dog, 틀:Ussc U.S. courts do not have criminal jurisdiction in cases where one Native American murders another on reservation lands. The Supreme Court also ruled that tribes held exclusive jurisdiction over their own internal affairs, including murder cases. The U.S. Congress responded with the Major Crimes Act, by which Congress has exercised since absolute (plenary) power over tribal jurisdiction by excluding certain crimes from that jurisdiction. This case was the beginning of the plenary power legal doctrine that has been used in Indian case law to limit tribal sovereignty.

• County of Oneida v. Oneida Indian Nation of New York State, 틀:Ussc Indian tribes have a federal common law cause of action, not preempted by the Nonintercourse Act, for possessory claims based upon aboriginal title; such action is not barred by limitations, abatement, ratification or nonjusticiability, and due to the Eleventh Amendment, there is no ancillary jurisdiction for counties' cross-claims against a state.
• Lyng v. Northwest Indian Cemetery Protective Association, 틀:Ussc The American Indian Religious Freedom Act of 1978 (AIRFA) does not create a cause of action under which to sue, nor does it contain any judicially enforceable rights.
• United States v. Lara, 틀:Ussc As an Indian tribe and the United States are separate sovereigns, both the United States and a Native American (Indian) tribe can prosecute an Indian for the same acts that constituted crimes in both jurisdictions without invoking double jeopardy if the actions of the accused violated Federal law.
• Herrera v. Wyoming, 틀:Ussc Wyoming's statehood did not void the Crow Tribe's right to hunt on "unoccupied lands of the United States" under an 1868 treaty, and that the Bighorn National Forest did not automatically become "occupied" when the forest was created.
• McGirt v. Oklahoma 틀:Ussc Oklahoma's land reserved for the Creek Nation since the 19th century remains "Indian country". Native Americans residing in the reservation cannot be criminally prosecuted by the state of Oklahoma.

• Tinker v. Des Moines Independent Community School District, 틀:Ussc Public school students have free speech rights under the First Amendment. Therefore, wearing armbands as a form of protest on public school grounds qualifies as protected symbolic speech.
• Brandenburg v. Ohio, 틀:Ussc The mere advocacy of the use of force or of violation of the law is protected by the First Amendment. Only inciting others to take direct and immediate unlawful action is without constitutional protection.

• Gertz v. Robert Welch, Inc., 틀:Ussc The First Amendment permits the states to formulate their own standards of liability for defamation against private individuals as long as liability is not imposed without fault.

• Texas v. Johnson, 틀:Ussc A Texas law that criminalizes the desecration of the American flag is unconstitutional because it violates the First Amendment's protection of symbolic speech.

• Kaelin v. Globe Communications, Case no. 97-55232 (3rd Cir. 1998) A headline on the cover of a magazine which "falsely insinuated" a criminal act may be grounds for a libel action even if the related article inside the magazine is not defamatory.

• Little v. Barreme, 틀:Ussc The President does not have "inherent authority" or "inherent powers" that allow him to ignore a law passed by the US Congress.
