Sovereign immunity, or crown immunity, is a legal doctrine whereby a sovereign or state cannot commit a legal wrong and is immune from civil suit or criminal prosecution, strictly speaking in modern texts in its own courts. A similar, stronger rule as regards foreign courts is named state immunity.
Church of the Lukumi Babalu Aye, Inc. v. Hialeah, 508 U.S. 520 (1993), was a case in which the Supreme Court of the United States held that an ordinance passed in Hialeah, Florida, forbidding the "unnecessar[y]" killing of "an animal in a public or private ritual or ceremony not for the primary purpose of food consumption", was unconstitutional.
In the United States, qualified immunity is a legal principle that grants government officials performing discretionary (optional) functions immunity from civil suits unless the plaintiff shows that the official violated "clearly established statutory or constitutional rights of which a reasonable person would have known". It is a form of sovereign immunity less strict than absolute immunity that is intended to protect officials who "make reasonable but mistaken judgments about open legal questions", extending to "all [officials] but the plainly incompetent or those who knowingly violate the law". Qualified immunity applies only to government officials in civil litigation, and does not protect the government itself from suits arising from officials' actions.
Judicial immunity is a form of sovereign immunity, which protects judges and others employed by the judiciary from liability resulting from their judicial actions. It is intended to ensure that judges can make decisions free from improper influenced exercised on them, contributing to the impartiality of the judiciary and the rule of law. In modern times, the main purpose of "judicial immunity [is to shield] judges from the suits of ordinary people", mainly litigants who may be dissatisfied with the outcome of a case decided by the judge.
The Speech or Debate Clause is a clause in the United States Constitution. The clause states that "The Senators and Representatives" of Congress "shall in all Cases, except Treason, Felony, and Breach of the Peace, be privileged from Arrest during their attendance at the Session of their Respective Houses, and in going to and from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place."

Village of Arlington Heights v. Metropolitan Housing Development Corp, 429 U.S. 252 (1977), was a case heard by the Supreme Court of the United States dealing with a zoning ordinance that in a practical way barred families of various socio-economic, and ethno-racial backgrounds from residing in a neighborhood. The Court held that the ordinance was constitutional because there was no proof that "discriminatory purpose was a motivating factor in the Village's decision."
Monell v. Department of Social Services, 436 U.S. 658 (1978), is an opinion given by the United States Supreme Court in which the Court overruled Monroe v. Pape by holding that a local government is a "person" subject to suit under Section 1983 of Title 42 of the United States Code: Civil action for deprivation of rights. Additionally, the Court held that §1983 claims against municipal entities must be based on implementation of a policy or custom.
Christensen v. Harris County, 529 U.S. 576 (2000), is a Supreme Court of the United States case holding that a county's policy of requiring employees to schedule time off to avoid accruing time off was not prohibited by the Fair Labor Standards Act.
In United States law, the federal government as well as state and tribal governments generally enjoy sovereign immunity, also known as governmental immunity, from lawsuits. Local governments in most jurisdictions enjoy immunity from some forms of suit, particularly in tort. The Foreign Sovereign Immunities Act provides foreign governments, including state-owned companies, with a related form of immunity—state immunity—that shields them from lawsuits except in relation to certain actions relating to commercial activity in the United States. The principle of sovereign immunity in US law was inherited from the English common law legal maxim rex non potest peccare, meaning "the king can do no wrong." In some situations, sovereign immunity may be waived by law.
Hunter v. Erickson, 393 U.S. 385 (1969), was a United States Supreme Court case.
Santa Clara Pueblo v. Martinez, 436 U.S. 49 (1978), was a landmark case in the area of federal Indian law involving issues of great importance to the meaning of tribal sovereignty in the contemporary United States. The Supreme Court sustained a law passed by the governing body of the Santa Clara Pueblo that explicitly discriminated on the basis of sex. In so doing, the Court advanced a theory of tribal sovereignty that weighed the interests of tribes sufficient to justify a law that, had it been passed by a state legislature or Congress, would have almost certainly been struck down as a violation of equal protection.
Forrester v. White, 484 U.S. 219 (1988), was a case decided on by the United States Supreme Court. The case restricted judicial immunity in certain instances.
Freedom suits were lawsuits in the Thirteen Colonies and the United States filed by slaves against slaveholders to assert claims to freedom, often based on descent from a free maternal ancestor, or time held as a resident in a free state or territory.
Pembaur v. City of Cincinnati, 475 U.S. 469 (1986), is a United States Supreme Court case that clarified a previous case, Monell v. Department of Social Services (1978), and established that municipalities can be held liable even for a single decision that is improperly made.
Heffernan v. City of Paterson, 578 U.S. ___ (2016), was a United States Supreme Court case in 2016 concerning the First Amendment rights of public employees. By a 6–2 margin, the Court held that a public employee's constitutional rights might be violated when an employer, believing that the employee was engaging in what would be protected speech, disciplines them because of that belief, even if the employee did not exercise such a constitutional right.
Lane v. Franks, 573 U.S. 228 (2014), is a U.S. Supreme Court case involving public employee's freedom of speech rights. Edward Lane sued Steve Franks for unfairly firing him, out of retaliation for sworn testimony Lane gave during a federal fraud case. The Eleventh Circuit originally ruled in favor of Franks, “denying [Lane] first amendment protection to subpoenaed testimony”. The case was argued before the Supreme Court on April 28, 2014. The case was decided on June 19, 2014.
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.
Pierson v. Ray, 386 U.S. 547 (1967), was a United States Supreme Court case in which the Court first introduced the justification for qualified immunity for police officers from being sued for civil rights violations under Section 1983, by arguing that "[a] policeman's lot is not so unhappy that he must choose between being charged with dereliction of duty if he does not arrest when he had probable cause, and being mulcted in damages if he does."
