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.
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.
Powell v. Alabama, 287 U.S. 45 (1932), was a landmark United States Supreme Court decision in which the Court reversed the convictions of nine young black men for allegedly raping two white women on a freight train near Scottsboro, Alabama. The majority of the Court reasoned that the right to retain and be represented by a lawyer was fundamental to a fair trial and that at least in some circumstances, the trial judge must inform a defendant of this right. In addition, if the defendant cannot afford a lawyer, the court must appoint one sufficiently far in advance of trial to permit the lawyer to prepare adequately for the trial.
Moore et al. v. Dempsey, 261 U.S. 86 (1923), was a United States Supreme Court case in which the Court ruled 6–2 that the defendants' mob-dominated trials deprived them of due process guaranteed by the Due Process Clause of the Fourteenth Amendment. It reversed the district court's decision declining the petitioners' writ of habeas corpus. This case was a precedent for the Supreme Court's review of state criminal trials in terms of their compliance with the Bill of Rights.
In American procedural law, a continuance is the postponement of a hearing, trial, or other scheduled court proceeding at the request of either or both parties in the dispute, or by the judge sua sponte. In response to delays in bringing cases to trial, some states have adopted "fast-track" rules that sharply limit the ability of judges to grant continuances. However, a motion for continuance may be granted when necessitated by unforeseeable events, or for other reasonable cause articulated by the movant, especially when the court deems it necessary and prudent in the "interest of justice."
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.
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:
The Compulsory Process Clause within the Sixth Amendment to the United States Constitution lets criminal case defendants attain witnesses in their favor by way of a court-ordered subpoena. The Clause is generally interpreted as letting defendants present their own case at trial, though several specific limitations have been placed by the Supreme Court of the United States since this rule began.
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.
Washington v. Texas, 388 U.S. 14 (1967), is a United States Supreme Court case in which the Court decided that the Compulsory Process Clause of the Sixth Amendment to the Constitution is applicable in state courts as well as federal courts. Jackie Washington had attempted to call his co-defendant as a witness, but was blocked by Texas courts because state law prevented co-defendants from testifying for each other, under the theory that they would be likely to lie for each other on the stand.
The blank pad rule is an American term for the legal doctrine and metaphor in common law that requires a tribunal to base its decision solely upon evidence established at trial. In the United States, the Supreme Court has established that in order for a trial to be fair and impartial, a "jury's verdict [must] be based on evidence received in open court, not from outside sources".
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.
Richmond Newspapers Inc. v. Virginia, 448 U.S. 555 (1980), is a United States Supreme Court case involving issues of privacy in correspondence with the First Amendment to the United States Constitution, the freedom of the press, the Sixth Amendment to the United States Constitution and the Fourteenth Amendment to the United States Constitution. After a murder case ended in three mistrials, the judge closed the fourth trial to the public and the press. On appeal, the Supreme Court ruled the closing to be in violation of the First Amendment and Fourteenth Amendment asserting that the First Amendment implicitly guarantees the press access to public trials.
Lafler v. Cooper, 566 U.S. 156 (2012), was a United States Supreme Court case in which the Court clarified the Sixth Amendment standard for reversing convictions due to ineffective assistance of counsel during plea bargaining. The Court ruled that when a lawyer's ineffective assistance leads to the rejection of a plea agreement, a defendant is entitled to relief if the outcome of the plea process would have been different with competent advice. In such cases, the Court ruled that the Sixth Amendment requires the trial judge to exercise discretion to determine an appropriate remedy.
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.
Napue v. Illinois, 360 U.S. 264 (1959), was a United States Supreme Court case in which the Court held that the knowing use of false testimony by a prosecutor in a criminal case violates the Due Process Clause of the Fourteenth Amendment to the United States Constitution, even if the testimony affects only the credibility of the witness and does not directly relate to the innocence or guilt of the defendant.
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.
Powers v. Ohio, 499 U.S. 400 (1991), was a United States Supreme Court case that re-examined the Batson Challenge. Established by Batson v. Kentucky, 476 U.S. 79 (1986), the Batson Challenge prohibits jury selectors from using peremptory challenges on the basis of race, ethnicity, gender, and sex. Powers expanded the jurisdictions of this principle, allowing all parties within a case, defendants especially, to question preemptory challenges during a jury selection, regardless of race. This holding was protected under the Equal Protection Clause of the Fourteenth Amendment.
Johnson v. Louisiana, 406 U. S. 356 (1972), was a court case in the U.S. Supreme Court involving the Due Process Clause and Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. The U.S. Supreme Court ruled that the Louisiana law that allowed less-than unanimous jury verdicts to convict persons charged with a felony, does not violate the Due Process clause. This case was argued on a similar basis as Apodaca v. Oregon.
