In the United States, the Miranda warning is a type of notification customarily given by police to criminal suspects in police custody advising them of their right to silence and, in effect, protection from self-incrimination; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. Named for the U.S. Supreme Court's 1966 decision Miranda v. Arizona, these rights are often referred to as Miranda rights. The purpose of such notification is to preserve the admissibility of their statements made during custodial interrogation in later criminal proceedings. The idea came from law professor Yale Kamisar, who subsequently was dubbed "the father of Miranda."
Miranda v. Arizona, 384 U.S. 436 (1966), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Fifth Amendment to the U.S. Constitution restricts prosecutors from using a person's statements made in response to interrogation in police custody as evidence at their trial unless they can show that the person was informed of the right to consult with an attorney before and during questioning, and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights but also voluntarily waived them.
In law, a reasonable person, reasonable man, or the man on the Clapham omnibus, is a hypothetical person of legal fiction crafted by the courts and communicated through case law and jury instructions.
In criminal procedure law of the United States, an exigent circumstance allows law enforcement to enter a structure without a search warrant, or if they have a "knock and announce" warrant, allows them to enter without knocking and waiting for the owner's permission to enter. It must be a situation where people are in imminent danger, evidence faces imminent destruction, or a suspect's escape is imminent. Once entry is obtained, the plain view doctrine applies, allowing the seizure of any evidence or contraband discovered in the course of actions consequent upon the exigent circumstances.
In criminal law, self-incrimination is the act of exposing oneself generally, by making a statement, "to an accusation or charge of crime; to involve oneself or another [person] in a criminal prosecution or the danger thereof". Self-incrimination can occur either directly or indirectly: directly, by means of interrogation where information of a self-incriminatory nature is disclosed; or indirectly, when information of a self-incriminatory nature is disclosed voluntarily without pressure from another person.
Dickerson v. United States, 530 U.S. 428 (2000), upheld the requirement that the Miranda warning be read to criminal suspects and struck down a federal statute that purported to overrule Miranda v. Arizona (1966).
Missouri v. Seibert, 542 U.S. 600 (2004), is a decision by the Supreme Court of the United States that struck down the police practice of first obtaining an inadmissible confession without giving Miranda warnings, then issuing the warnings, and then obtaining a second confession. Justice David Souter announced the judgment of the Court and wrote for a plurality of four justices that the second confession was admissible only if the intermediate Miranda warnings were "effective enough to accomplish their object." Justice Anthony Kennedy wrote in a concurring opinion that the second confession should be inadmissible only if "the two-step interrogation technique was used in a calculated way to undermine the Miranda warning."
eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), is a case in which the Supreme Court of the United States unanimously determined that an injunction should not be automatically issued based on a finding of patent infringement, but also that an injunction should not be denied simply on the basis that the plaintiff does not practice the patented invention. Instead, a federal court must still weigh what the Court described as the four-factor test traditionally used to determine if an injunction should be issued.
Massiah v. United States, 377 U.S. 201 (1964), was a case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution prohibits the government from eliciting statements from the defendant about themselves after the point that the Sixth Amendment right to counsel attaches.
The Fifth Amendment to the United States Constitution creates several constitutional rights, limiting governmental powers focusing on criminal procedures. It was ratified, along with nine other articles, in 1791 as part of the Bill of Rights.
Arizona v. Gant, 556 U.S. 332 (2009), was a United States Supreme Court decision holding that the Fourth Amendment to the United States Constitution requires law-enforcement officers to demonstrate an actual and continuing threat to their safety posed by an arrestee, or a need to preserve evidence related to the crime of arrest from tampering by the arrestee, in order to justify a warrantless vehicular search incident to arrest conducted after the vehicle's recent occupants have been arrested and secured.
Berghuis v. Thompkins, 560 U.S. 370 (2010), is a landmark decision by the Supreme Court of the United States in which the Court considered the position of a suspect who understands their right to remain silent under Miranda v. Arizona and is aware that they have the right to remain silent, but does not explicitly invoke or waive the right.
Chamber of Commerce v. Whiting, 563 U.S. 582 (2011), is a decision by the Supreme Court of the United States that upheld an Arizona state law suspending or revoking business licenses of businesses that hire illegal aliens.
J.D.B. v. North Carolina, 564 U.S. 261 (2011), was a case in which the Supreme Court of the United States held that age and mental status is relevant when determining police custody for Miranda purposes, overturning its prior ruling from seven years before. J.D.B. was a 13-year-old student enrolled in special education classes whom police had suspected of committing two robberies. A police investigator visited J.D.B. at school, where he was interrogated by the investigator, a uniformed police officer, and school officials. J.D.B. subsequently confessed to his crimes and was convicted. J.D.B. was not given a Miranda warning during the interrogation, nor an opportunity to contact his legal guardian.
Yarborough v. Alvarado, 541 U.S. 652 (2004), is a United States Supreme Court case in which the Court declined to overturn a state court's conclusion that a minor was not in custody for Miranda purposes during his police interview. Michael Alvarado helped his friend Paul Soto steal a truck in Santa Fe Springs, California. The truck owner was killed by Soto during the robbery and Alvarado was convicted of second-degree murder for his role in the crime. The evidence for Alvarado's conviction was primarily based on statements given by Alvarado during a two-hour police interrogation that occurred when Alvarado's parents brought him to the police station. Alvarado was 17 years old and was not read his Miranda rights before questioning. During Alvarado's murder trial in a state court, motions to suppress the statements given by Alvarado were denied on the ground that Alvarado was not in police custody at the time of the interrogation and thus did not have to be read his Miranda rights. Alvarado appealed his conviction, claiming that the determination that he was not in custody was incorrect because the courts did not take his age into account.
Leal Garcia v. Texas, 564 U.S. 940 (2011), was a ruling in which the Supreme Court of the United States denied Humberto Leal García's application for stay of execution and application for writ of habeas corpus. Leal was subsequently executed by lethal injection. The central issue was not Leal's guilt, but rather that he was not notified of his right to call his consulate as required by international law. The Court did not stay the execution because Congress had never enacted legislation regarding this provision of international law. The ruling attracted a great deal of commentary and Leal's case was supported by attorneys specializing in international law and several former United States diplomats.
Bailey v. United States, 568 U.S. 186 (2013), was a United States Supreme Court case concerning search and seizure. A 6–3 decision reversed the weapons conviction of a Long Island man who had been detained when police followed his vehicle after he left his apartment just before it was to be searched. Justice Anthony Kennedy wrote the majority opinion, and Antonin Scalia filed a concurrence. Stephen Breyer dissented.
Reed v. Town of Gilbert, 576 U.S. 155 (2015), is a case in which the United States Supreme Court clarified when municipalities may impose content-based restrictions on signage. The case also clarified the level of constitutional scrutiny that should be applied to content-based restrictions on speech. In 2005, Gilbert, Arizona adopted a municipal sign ordinance that regulated the manner in which signs could be displayed in public areas. The ordinance imposed stricter limitations on signs advertising religious services than signs that displayed "political" or "ideological" messages. When the town's Sign Code compliance manager cited a local church for violating the ordinance, the church filed a lawsuit in which they argued the town's sign regulations violated its First Amendment right to the freedom of speech.
Crooker v. California, 357 U.S. 433 (1958), was a decision by the Supreme Court of the United States that limited criminal suspects' constitutional right to counsel before trial, refusing to overturn a subsequent conviction without a showing that the refusal of counsel had a coercive or prejudicial effect. This holding was later overturned by Escobedo v. Illinois and Miranda v. Arizona.
In US patent law, non-obviousness is one of the requirements that an invention must meet to qualify for patentability, codified as a part of Patent Act of 1952 as 35 U.S.C. §103. An invention is not obvious if a "person having ordinary skill in the art" (PHOSITA) would not know how to solve the problem at which the invention is directed by using exactly the same mechanism. Since the PHOSITA standard turned to be too ambiguous in practice, the U.S. Supreme Court provided later two more useful approaches which currently control the practical analysis of non-obviousness by patent examiners and courts: Graham et al. v. John Deere Co. of Kansas City et al., 383 U.S. 1 (1966) gives guidelines of what is "non-obvious", and KSR v. Teleflex (2006) gives guidelines of what is "obvious".
