In jurisprudence, double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal or conviction and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. Double jeopardy is a common concept in criminal law. In civil law, a similar concept is that of res judicata. Variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit or autrefois convict. These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem.
In legal terms, a plea is simply an answer to a claim made by someone in a criminal case under common law using the adversarial system. Colloquially, a plea has come to mean the assertion by a defendant at arraignment, or otherwise in response to a criminal charge, whether that person pleaded or pled guilty, not guilty, nolo contendere, no case to answer, or Alford plea.
The Sixth Amendment to the United States Constitution sets forth rights related to criminal prosecutions. It was ratified in 1791 as part of the United States Bill of Rights. The Supreme Court has applied all but one of this amendment's protections to the states through the Due Process Clause of the Fourteenth Amendment.
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,[which?] 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.
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.
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.
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:
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.
United States v. Josef Perez, 22 U.S. 579 (1824), is a case of the Supreme Court of the United States. The decision held that when a criminal trial results in a hung jury, the Double Jeopardy Clause of the Fifth Amendment does not prevent the defendant from being retried.
The United States Constitution contains several provisions regarding the law of criminal procedure.
Glasser v. United States, 315 U.S. 60 (1942), was a landmark decision of the US Supreme Court on two issues of constitutional criminal procedure. Glasser was the first Supreme Court decision to hold that the Assistance of Counsel Clause of the Sixth Amendment required the reversal of a criminal defendant's conviction if his lawyer's representation of him was limited by a conflict of interest.
North Carolina v. Pearce, 395 U.S. 711 (1969), is a United States Supreme Court case that forbids judicial “vindictiveness” from playing a role in the increased sentence a defendant receives after a new trial. In sum, due process requires that a defendant be “free of apprehension” of judicial vindictiveness. Time served for a new conviction of the same offense must be “fully credited,” and a trial judge seeking to impose a greater sentence on retrial must affirmatively state the reasons for imposing such a sentence.
Taylor v. Illinois, 484 U.S. 400 (1988), is a United States Supreme Court decision in which the Court held that defense witnesses can be prevented from testifying under certain circumstances, even if that hurts the defense's case. Taylor was the first case to hold that there is no absolute bar to blocking the testimony of a surprise witness, even if that is an essential witness for the defendant, a limitation of the broad right to present a defense recognized in Washington v. Texas (1967).
Blueford v. Arkansas, 566 U.S. 599 (2012), was a decision of the Supreme Court of the United States that clarified the limits of the Double Jeopardy Clause. The Supreme Court held that the Double Jeopardy Clause does not bar retrial of counts that a jury had previously unanimously voted to acquit on, when a mistrial is declared after the jury deadlocked on a lesser included offense.
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.
Oregon v. Kennedy, 456 U.S. 667 (1982), was a United States Supreme Court decision dealing with the appropriate test for determining whether a criminal defendant has been "goaded" by the prosecution's bad actions into motioning for a mistrial. This matters because the answer determines whether a defendant can be retried. Ordinarily, a defendant who requests a mistrial can be forced to stand trial a second time, see United States v. Dinitz. However, if the prosecution's conduct was "intended to provoke the defendant into moving for a mistrial," double jeopardy protects the defendant from retrial. The Court emphasized that only prosecutorial actions where the intent is to provoke a mistrial — and not mere "harassment" or "overreaching" — trigger the double jeopardy protection.
United States v. Jorn, 400 U.S. 470 (1971), was a United States Supreme Court decision clarifying when a criminal defendant may be retried after a mistrial. In this case, where a trial judge abruptly declared a mistrial to prevent the prosecution's witness from incriminating himself, a second trial was barred by the Double Jeopardy Clause.
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.
