In common law jurisdictions, an acquittal means that the prosecution has failed to prove that the accused is guilty beyond a reasonable doubt of the charge presented. It certifies that the accused is free from the charge of an offense, as far as criminal law is concerned. The finality of an acquittal is dependent on the jurisdiction. In some countries, such as the United States, an acquittal prohibits the retrial of the accused for the same offense, even if new evidence surfaces that further implicates the accused. The effect of an acquittal on criminal proceedings is the same whether it results from a jury verdict or results from the operation of some other rule that discharges the accused. In other countries, like Australia and the UK, the prosecuting authority may appeal an acquittal similar to how a defendant may appeal a conviction — but usually only if new and compelling evidence comes to light or the accused has interfered with or intimidated a juror or witness.
Palko v. Connecticut, 302 U.S. 319 (1937), was a United States Supreme Court case concerning the incorporation of the Fifth Amendment protection against double jeopardy.
Benton v. Maryland, 395 U.S. 784 (1969), is a Supreme Court of the United States decision concerning double jeopardy. Benton ruled that the Double Jeopardy Clause of the Fifth Amendment applies to the states. In doing so, Benton expressly overruled Palko v. Connecticut.
Fong Foo v. United States, 369 U.S. 141 (1962), was a Supreme Court ruling that upheld the protection from double jeopardy by the federal government. While the protection from double jeopardy did not get incorporated to apply to the state governments until 1969, the Supreme Court ruled that the Fifth Amendment to the United States Constitution prevented the Federal Government from bringing a defendant to trial twice for the same charge. In this case, the court ruled that despite the error of the District Judge, the 5th Amendment protected the defendants from facing a second trial for the same charge.
Heath v. Alabama, 474 U.S. 82 (1985), is a case in which the United States Supreme Court ruled that, because of the doctrine of "dual sovereignty", the double jeopardy clause of the Fifth Amendment to the Constitution does not prohibit one state from prosecuting and punishing somebody for an act of which they had already been convicted of and sentenced for in another state.
United States v. Felix, 503 U.S. 378 (1992), was a decision by the United States Supreme Court, which held that "a[n]…offense and a conspiracy to commit that offense are not the same offense for double jeopardy purposes." The Supreme Court rejected the Tenth Circuit's reversal of Felix's conviction, finding that the Court of Appeals read the holding in Grady v. Corbin (1990) too broadly.
The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides: "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb..." The four essential protections included are prohibitions against, for the same offense:
Grady v. Corbin, 495 U.S. 508 (1990), was a United States Supreme Court decision holding that: "the Double Jeopardy Clause bars a subsequent prosecution if, to establish an essential element of an offense charged in that prosecution, the government will prove conduct that constitutes an offense for which the defendant has already been prosecuted."
Waller v. Florida, 397 U.S. 387 (1970), was a decision by the United States Supreme Court, which held that the Double Jeopardy Clause protects defendants from successive prosecutions by states and municipalities for offenses based on the same criminal conduct.
Blockburger v. United States, 284 U.S. 299 (1932), was a case in which the Supreme Court of the United States set an important standard to prevent double jeopardy.
United States v. Lara, 541 U.S. 193 (2004), was a United States Supreme Court landmark case which held that both the United States and a Native American (Indian) tribe could prosecute an Indian for the same acts that constituted crimes in both jurisdictions. The Court held that the United States and the tribe were separate sovereigns; therefore, separate tribal and federal prosecutions did not violate the Double Jeopardy Clause.
Ludwig v. Massachusetts, 427 U.S. 618 (1976), was a case in which the Supreme Court of the United States held that the Massachusetts two-tier court system did not deprive Ludwig of his U.S. Const., Amend. XIV right to a jury trial and did not violate the double jeopardy clause of the U.S. Const., Amend. V.
United States v. Wheeler, 435 U.S. 313 (1978), was a United States Supreme Court case in which the Court held the Double Jeopardy Clause does not bar the federal prosecution of a Native American (Indian) who has already been prosecuted by the tribe.
Abbate v. United States, 359 U.S. 187 (1959), is a decision of the U.S. Supreme Court. The decision held that the double jeopardy Clause of the Fifth Amendment to the U.S. Constitution does not prohibit the prosecution of a conspiracy in federal court under federal law when that same conspiracy has already resulted in a conviction in state court under state law.
Puerto Rico v. Sanchez Valle, 579 U.S. 59 (2016), is a criminal case that came before the Supreme Court of the United States, which considered whether Puerto Rico and the federal government of the United States are separate sovereigns for purposes of the Double Jeopardy Clause of the United States Constitution.
United States v. Dixon, 509 U.S. 688 (1993), was a decision of the United States Supreme Court concerning double jeopardy. The case overruled Grady v. Corbin (1990) and revived the traditional Blockburger standard. The case held that subsequent convictions for offenses that contained the same elements were violative of the Double Jeopardy Clause.
Burks v. United States, 437 U.S. 1 (1978), is a United States Supreme Court decision that clarified both the scope of the protection against double jeopardy provided by the Fifth Amendment to the United States Constitution and the limits of an appellate court's discretion to fashion a remedy under section 2106 of Title 28 to the United States Code. It established the constitutional rule that where an appellate court reverses a criminal conviction on the ground that the prosecution failed to present sufficient evidence to prove the defendant's guilt beyond a reasonable doubt, the Double Jeopardy Clause shields the defendant from a second prosecution for the same offense. Notwithstanding the power that appellate courts have under section 2106 to "remand the cause and direct the entry of such appropriate judgment, decree, or order, or require such further proceedings to be had as may be just under the circumstances," a court that reverses a conviction for insufficiency of the evidence may not allow the lower court a choice on remand between acquitting the defendant and ordering a new trial. The "only 'just' remedy" in this situation, the Court held, is to order an acquittal.
Gamble v. United States, No. 17-646, 587 U.S. ___ (2019), was a United States Supreme Court case about the separate sovereignty exception to the Double Jeopardy Clause of the Fifth Amendment to the United States Constitution, which allows both federal and state prosecution of the same crime as the governments are "separate sovereigns". Terance Martez Gamble was prosecuted under both state and then federal laws for possessing a gun while being a felon. His argument that doing so was double jeopardy was found unpersuasive due to the exception. In June 2019, the Supreme Court affirmed the lower court decision 7–2, with the majority opinion stating that there was not sufficient cause for overturning the dual sovereignty doctrine.
Cassirer v. Thyssen-Bornemisza Collection Foundation, 596 U.S. ___ (2022), was a United States Supreme Court case in which the Court held that, in a suit raising non-federal claims against a foreign state or instrumentality under the Foreign Sovereign Immunities Act, a court should determine the substantive law by using the same choice-of-law rule applicable in a similar suit against a private party.
United States v. Taylor, 596 U.S. ___ (2022), was a United States Supreme Court case in which the Court held that an attempted Hobbs Act robbery does not qualify as a "crime of violence" under 18 U.S.C. § 924(c)(3)(A) because no element of the offense requires proof that the defendant used, attempted to use, or threatened to use force.
