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. The double jeopardy protection in criminal prosecutions only bars an identical prosecution for the same offense, however, a different offense may be charged on identical evidence at a second trial. Res judicata protection is stronger - it precludes any causes of action or claims that arise from a previously litigated subject matter.
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.
Hamdan v. Rumsfeld, 548 U.S. 557 (2006), is a United States Supreme Court case in which the Court held that military commissions set up by the Bush administration to try detainees at Guantanamo Bay violated both the Uniform Code of Military Justice (UCMJ) and the Geneva Conventions ratified by the U.S.
In law, the venue is the location where a case is heard.
Whorton v. Bockting, 549 U.S. 406 (2007), was a United States Supreme Court case about the application of the Confrontation Clause and whether Crawford v. Washington (2006) applied retroactively. Justice Samuel Alito, writing for a unanimous Court, ruled that Crawford did not apply retroactively.
Smith v. Texas, 550 U.S. 297 (2007), was a United States Supreme Court case about a challenge to a Texas death penalty court procedure. Justice Anthony Kennedy wrote the opinion of the Court, holding 5-4 that the Texas procedure was improper. Justice Samuel Alito wrote a dissent.
Kennedy v. Louisiana, 554 U.S. 407 (2008), is a landmark decision by the Supreme Court of the United States which held that the Eighth Amendment's Cruel and Unusual Punishments Clause prohibits the imposition of the death penalty for a crime in which the victim did not die and the victim's death was not intended.
United States criminal procedure derives from several sources of law: the baseline protections of the United States Constitution; federal and state statutes; federal and state rules of criminal procedure ; and state and federal case law. Criminal procedures are distinct from civil procedures in the US.
Snyder v. Louisiana, 552 U.S. 472 (2008), was a United States Supreme Court case about racial issues in jury selection in death penalty cases. Justice Samuel Alito, writing for the 7–2 majority, ruled that the prosecutor's use of peremptory strikes to remove African American jurors violated the Court's earlier holding in Batson v. Kentucky. Justice Clarence Thomas dissented.
Giles v. California, 554 U.S. 353 (2008), was a case decided by the Supreme Court of the United States that held that for testimonial statements to be admissible under the forfeiture exception to hearsay, the defendant must have intended to make the witness unavailable for trial.
United States v. Dinitz, 424 U.S. 600 (1976), was a case in which the Supreme Court of the United States determined that the U.S. Const., Amend. V protection against double jeopardy did not prevent a retrial of a defendant, who had previously requested a mistrial.
The United States Constitution contains several provisions regarding the law of criminal procedure.
The Vicinage Clause is a provision in the Sixth Amendment to the United States Constitution regulating the vicinity from which a jury pool may be selected. The clause says that the accused shall be entitled to an "impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law". The Vicinage Clause limits the vicinity of criminal jury selection to both the state and the federal judicial district where the crime has been committed. This is distinct from the venue provision of Article Three of the United States Constitution, which regulates the location of the actual trial.
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.
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.
McCoy v. Louisiana, 584 U.S. ___ (2018), was a United States Supreme Court case in which the Court held the Sixth Amendment guarantees a defendant the right to decide that the objective of his defense is to maintain innocence at all costs, even when counsel believes that admitting guilt offers the defendant the best chance to avoid the death penalty.
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.
Ramos v. Louisiana, 590 U.S. ___ (2020), was a U.S. Supreme Court decision in which the Court ruled that the Sixth Amendment to the U.S. Constitution requires that guilty verdicts be unanimous in trials for serious crimes. Only cases in Oregon and Louisiana were affected by the ruling because every other state already had this requirement. The decision incorporated the Sixth Amendment requirement for unanimous jury criminal convictions against the states, and thereby overturned the Court's previous decision from the 1972 cases Apodaca v. Oregon and Johnson v. Louisiana.
Samia v. United States, 599 U.S. 635 (2023), was a United States Supreme Court case related to the Confrontation Clause of the Sixth Amendment to the United States Constitution.
