In United States constitutional law, the good-faith exception is a legal doctrine providing an exemption to the exclusionary rule.
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.
The United States Reports are the official record of the Supreme Court of the United States. They include rulings, orders, case tables, in alphabetical order both by the name of the petitioner and by the name of the respondent, and other proceedings. United States Reports, once printed and bound, are the final version of court opinions and cannot be changed. Opinions of the court in each case are prepended with a headnote prepared by the Reporter of Decisions, and any concurring or dissenting opinions are published sequentially. The Court's Publication Office oversees the binding and publication of the volumes of United States Reports, although the actual printing, binding, and publication are performed by private firms under contract with the United States Government Publishing Office.
Herring v. United States, 555 U.S. 135 (2009), was a case decided by the Supreme Court of the United States on January 14, 2009. The court decided that the good-faith exception to the exclusionary rule applies when a police officer makes an arrest based on an outstanding warrant in another jurisdiction, but the information regarding that warrant is later found to be incorrect because of a negligent error by that agency.
Roberts v. United States Jaycees, 468 U.S. 609 (1984), was a decision of the Supreme Court of the United States overturning the United States Court of Appeals for the Eighth Circuit's application of a Minnesota antidiscrimination law. The case established what was at the time the prevailing framework for analyzing claims of associative freedom, holding that the Minneapolis branch of the United States Jaycees could not bar women from becoming voting members.
United States v. Karo, 468 U.S. 705 (1984), was a United States Supreme Court decision related to the Fourth Amendment protection from unreasonable search and seizure. It held that use of an electronic beeper device to monitor a can of ether without a warrant constituted an unlawful search. However, the Court upheld the conviction of Karo and his accomplices, stating that the warrant affidavit contained enough information not derived from the unlawful use of the beeper to provide sufficient basis for probable cause.
Spaziano v. Florida was two United States Supreme Court cases dealing with the imposition of the death penalty. In the first case, 454 U.S. 1037 (1981), the Supreme Court, with two dissents, refused Spaziano's petition for certiorari. However, the Florida Supreme Court would reverse Spaziano's death sentence based on the judge's receipt of a confidential report which was not received by either party. On remand, the judge reimposed the death penalty and the Florida Supreme Court upheld the sentence. In the second case, 468 U.S. 447 (1984), the Court heard Spaziano's appeal of his death sentence.
City of Dallas v. Stanglin, 490 U.S. 19 (1989), was a United States Supreme Court decision considering the First Amendment associational rights of teenagers at a dance hall. The Court upheld an ordinance imposing age limits on teen dance halls, ruling that gathering for recreational dancing is not an "expressive association" under the First Amendment.
Regan v. Wald, 468 U.S. 222 (1984), was a United States Supreme Court case in which the Court held by a 5–4 majority that restrictions upon travel to Cuba established as part of the Cuban Assets Control Regulations in 1963 did not violate the freedom to travel protected by the Due Process Clause of the Fifth Amendment.
