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 8–0 decision that Pennsylvania's Nonpublic Elementary and Secondary Education Act from 1968 was unconstitutional and in an 8–1 decision that Rhode Island's 1969 Salary Supplement Act was unconstitutional, violating the Establishment Clause of the First Amendment. The act allowed the Superintendent of Public Schools to reimburse private schools for the salaries of teachers who taught in these private elementary schools from public textbooks and with public instructional materials. Lemon was a major precedent in federal and local courts until it was effectively overturned by Kennedy v. Bremerton School District in 2022.
Rochin v. California, 342 U.S. 165 (1952), was a case decided by the Supreme Court of the United States that added behavior that "shocks the conscience" into tests of what violates due process clause of the 14th Amendment. This balancing test is often criticized as having subsequently been used in a particularly subjective manner.
Branzburg v. Hayes, 408 U.S. 665 (1972), was a landmark decision of the US Supreme Court invalidating the use of the First Amendment as a defense for reporters summoned to testify before a grand jury. The case was argued February 23, 1972, and decided June 29 of the same year. The reporters lost their case by a vote of 5–4. This case is cited for the rule that in federal courts, a reporter may not generally avoid testifying in a criminal grand jury, and is one of a limited number of cases in which the U.S. Supreme Court has considered the use of reporters' privilege.
Herrera v. Collins, 506 U.S. 390 (1993), was a case in which the Supreme Court of the United States ruled by 6 votes to 3 that a claim of actual innocence does not entitle a petitioner to federal habeas corpus relief by way of the Eighth Amendment's ban on cruel and unusual punishment.
BMW of North America, Inc. v. Gore, 517 U.S. 559 (1996), was a United States Supreme Court case limiting punitive damages under the Due Process Clause of the Fourteenth Amendment.
United States v. Leon, 468 U.S. 897 (1984), was a United States Supreme Court case in which the Court established the "good faith" exception to the Fourth Amendment exclusionary rule.
Shocks the conscience is a phrase used as a legal standard in the United States and Canada. An action is understood to "shock the conscience" if it is "grossly unjust to the observer."
Nebraska Press Association v. Stuart, 427 U.S. 539 (1976), was a landmark Supreme Court of the United States decision in which the Court held unconstitutional prior restraints on media coverage during criminal trials.
Parratt v. Taylor, 451 U.S. 527 (1981), was a case decided by the United States Supreme Court, in which the court considered the applicability of Due Process to a claim brought under Section 1983.
Schmerber v. California, 384 U.S. 757 (1966), was a landmark United States Supreme Court case in which the Court clarified the application of the Fourth Amendment's protection against warrantless searches and the Fifth Amendment right against self-incrimination for searches that intrude into the human body. Until Schmerber, the Supreme Court had not yet clarified whether state police officers must procure a search warrant before taking blood samples from criminal suspects. Likewise, the Court had not yet clarified whether blood evidence taken against the wishes of a criminal suspect may be used against that suspect in the course of a criminal prosecution.
Farmer v. Brennan, 511 U.S. 825 (1994), was a case in which the Supreme Court of the United States ruled that a prison official's "deliberate indifference" to a substantial risk of serious harm to an inmate violates the cruel and unusual punishment clause of the Eighth Amendment. Farmer built on two previous Supreme Court decisions addressing prison conditions, Estelle v. Gamble and Wilson v. Seiter. The decision marked the first time the Supreme Court directly addressed sexual assault in prisons.
Soldal v. Cook County, 506 U.S. 56 (1992), was a United States Supreme Court case in which the Court held that a seizure of property like that which occurs during an eviction, even absent a search or an arrest, implicates the Fourth Amendment. The Court also held that the Amendment protects property as well as privacy interests, in both criminal as well as civil contexts. Finally, saying that "certain wrongs affect more than a single right", the Court left open the possibility that the Fourteenth Amendment's protections against deprivation of property without due process of law may also be implicated.
Chavez v. Martinez, 538 U.S. 760 (2003), was a decision of the United States Supreme Court, which held that a police officer does not deprive a suspect of constitutional rights by failing to issue a Miranda warning. However, the court held open the possibility that the right to substantive due process could be violated in certain egregious circumstances and remanded the case to the lower court to decide this issue on the case's facts.
Breithaupt v. Abram, 352 U.S. 432 (1957), was a United States Supreme Court case in which the Court ruled that involuntary blood samples, taken by a skilled technician to determine intoxication, do not violate substantive due process under the Fourteenth Amendment of the United States Constitution. This case was only the second time the Court considered whether police could forcibly enter inside a suspect's body to extract evidence. Writing for a 6–3 majority, Justice Tom C. Clark argued that blood tests were necessary as a matter of public policy to ensure traffic safety on roads and highways, and that "modern community living requires modern scientific methods of crime detection." Chief Justice Earl Warren and Justice William O. Douglas both wrote dissenting opinions in which they argued that the involuntary blood sample taken in this case was "repulsive" and violated substantive due process.
The Supreme Court of the United States handed down eighteen per curiam opinions during its 2015 term, which began October 5, 2015 and concluded October 2, 2016.
Kingsley v. Hendrickson, 576 U.S. 389 (2015), is a United States Supreme Court case in which the Court held in a 5–4 decision that a pretrial detainee must prove only that force used by police is excessive according to an objective standard, not that a police officer was subjectively aware that the force used was unreasonable.
Voisine v. United States, 579 U.S. 686 (2016), was a United States Supreme Court case in which the Court held that the Domestic Violence Offender Gun Ban in U.S. federal law extends to those convicted of reckless domestic violence. The court reached its judgment in a 6–2 majority.
Plumhoff v. Rickard, 572 U.S. 765 (2014), is a United States Supreme Court case involving the use of force by police officers during high-speed car chases. After first holding that it had jurisdiction to hear the case, the Court held that the conduct of the police officers involved in the case did not violate the Fourth Amendment to the U.S. Constitution, which prohibits unreasonable searches and seizures.
Barr v. American Assn. of Political Consultants, Inc., 591 U.S. ___ (2020), was a United States Supreme Court case involving the use of robocalls made to cell phones, a practice that had been banned by the Telephone Consumer Protection Act of 1991 (TCPA), but which exemptions had been made by a 2015 amendment for government debt collection. The case was brought by the American Association of Political Consultants, an industry trade group, and others that desired to use robocalls to make political ads, challenging the exemption unconstitutionally favored debt collection speech over political speech. The Supreme Court, in a complex plurality decision, ruled on July 6, 2020, that the 2015 amendment to the TCPA did unconstitutionally favor debt collection speech over political speech and violated the First Amendment.
Lange v. California, 594 U.S. ___ (2021), was a United States Supreme Court case involving the exigent circumstances requirement related to the Fourth Amendment to the United States Constitution. The Court ruled unanimously that the warrantless entry into a home by police in pursuit of a misdemeanant is not unequivocally justified.
