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 jurisprudence, selective prosecution is a procedural defense in which defendants argue that they should not be held criminally liable for breaking the law, as the criminal justice system discriminated against them by choosing to prosecute. In claims of selective prosecution, defendants essentially argue that it is irrelevant whether they are guilty of violating a law, but that the fact of being prosecuted is based upon forbidden reasons. Such a claim might, for example, entail an argument that persons of different age, race, religion, sex, gender, or political alignment, were engaged in the same illegal acts for which the defendant is being tried yet were not prosecuted, and that the defendant is being prosecuted specifically because of a bias as to that class.
United States v. X-Citement Video, Inc., 513 U.S. 64 (1994), was a federal criminal prosecution filed in the United States District Court for the Central District of California in Los Angeles against X-Citement Video and its owner, Rubin Gottesman, on three charges of trafficking in child pornography, specifically videos featuring the underaged Traci Lords. In 1989, a federal judge found Gottesman guilty and later sentenced him to one year in jail and a $100,000 fine.
Nolle prosequi, abbreviated nol or nolle pros, is legal Latin meaning "to be unwilling to pursue". It is a type of prosecutorial discretion in common law, used for prosecutors' declarations that they are voluntarily ending a criminal case before trial or before a verdict is rendered; it is a kind of motion to dismiss and contrasts with an involuntary dismissal. This has been used frequently in the Commonwealth of Virginia.
Hartman v. Moore, 547 U.S. 250 (2006), is a decision by the Supreme Court of the United States involving the pleading standard for retaliatory prosecution claims against government officials. After a successful lobbying attempt by the CEO of a manufacturing company against competing devices that the US Postal Service supported, the CEO found himself the target of an investigation by US postal inspectors and a criminal prosecution that was dismissed for lack of evidence. The CEO then filed suit against the inspectors and other government officials for seeking to prosecute him in retaliation for exercising his First Amendment rights to criticize postal policy. The Court ruled 5-2 that to prove that the prosecution was caused by a retaliatory motive, the plaintiff bringing such a claim must allege and prove that the criminal charges were brought without probable cause.
Sorrells v. United States, 287 U.S. 435 (1932), is a Supreme Court case in which the justices unanimously recognized the entrapment defense. However, while the majority opinion by Chief Justice Charles Evans Hughes located the key to entrapment in the defendant's predisposition or lack thereof to commit the crime, Owen Roberts' concurring opinion proposed instead that it be rooted in an analysis of the conduct of the law enforcement agents making the arrest. Although the Court has stuck with predisposition, the dispute has hung over entrapment jurisprudence ever since.
Duro v. Reina, 495 U.S. 676 (1990), was a United States Supreme Court case in which the Court concluded that Indian tribes could not prosecute Indians who were members of other tribes for crimes committed by those nonmember Indians on their reservations. The decision was not well received by the tribes, because it defanged their criminal codes by depriving them of the power to enforce them against anyone except their own members. In response, Congress amended a section of the Indian Civil Rights Act, 25 U.S.C. § 1301, to include the power to "exercise criminal jurisdiction over all Indians" as one of the powers of self-government.
The Speedy Trial Act of 1974, establishes time limits for completing the various stages of a federal criminal prosecution in the United States.
Harris v. McRae, 448 U.S. 297 (1980), was a case in which the Supreme Court of the United States held that states participating in Medicaid are not required to fund medically necessary abortions for which federal reimbursement was unavailable as a result of the Hyde Amendment, which restricted the use of federal funds for abortion. The Court also held that the funding restrictions of the Hyde Amendment did not violate the Fifth Amendment or the Establishment Clause of the First Amendment.
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.
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:
Farmer v. Brennan, 511 U.S. 825 (1994), was a case in which the Supreme Court of the United States ruled that a prison official's "deliberate indifference" to a substantial risk of serious harm to an inmate violates the cruel and unusual punishment clause of the Eighth Amendment. Farmer built on two previous Supreme Court decisions addressing prison conditions, Estelle v. Gamble and Wilson v. Seiter. The decision marked the first time the Supreme Court directly addressed sexual assault in prisons.
United States v. Valenzuela-Bernal, 458 U.S. 858 (1982), is a United States Supreme Court case that determined the constitutionality of deporting aliens who might give testimony in criminal alien smuggling prosecutions. Because deporting alien witnesses might take away a testimony that would be both “material and favorable” to the defendant, it gives rise to a potential motion from the defense to dismiss the indictment under the Compulsory Process Clause of the Sixth Amendment and the Due Process Clause of the Fifth Amendment.
The United States Constitution contains several provisions regarding the law of criminal procedure.
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).
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.
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.
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.
TransUnion LLC v. Ramirez, 594 U.S. ___ (2021), was a United States Supreme Court case dealing with standing under Article III of the Constitution related to class-action suits against private defendants. In a 5–4 decision, the Court ruled that only those that can show concrete harm have standing to seek damages against private defendants.
