Double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal in the same jurisdiction. A variation in civil 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 most of the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
Jury nullification (US), jury equity (UK), or a perverse verdict (UK) generally occurs when members of a criminal trial jury believe that a defendant is guilty, but choose to acquit the defendant anyway, because the jurors consider that the law itself is unjust, that the prosecutor has misapplied the law in the defendant's case, or that the potential punishment for breaking the law is too harsh. Some juries have also refused to convict due to their own prejudices in favour of the defendant.
In common law jurisdictions, an acquittal certifies that the accused is free from the charge of an offense, as far as the criminal law is concerned. The finality of an acquittal is dependent on the jurisdiction. In some countries, such as the United States, an acquittal operates to bar 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, the prosecuting authority may appeal an acquittal similar to how a defendant may appeal a conviction.
United States v. Alvarez-Machain, 504 U.S. 655 (1992), was a United States Supreme Court case in which the Court held that the fact of respondent's forcible abduction does not prohibit his trial in a United States court for violations of this country's criminal laws. It re-confirmed the Ker-Frisbie Doctrine established in Ker v. Illinois (1886) and Frisbie v. Collins (1952).
In law, sua sponte or suo motu describes an act of authority taken without formal prompting from another party. The term is usually applied to actions by a judge taken without a prior motion or request from the parties. The form nostra sponte is sometimes used by the court itself, when the action is taken by a multi-member court, such as an appellate court, rather than by a single judge. While usually applied to actions of a court, the term may reasonably be applied to actions by government agencies and individuals acting in official capacity.
A new trial or retrial is a recurrence of a court case. Depending on the rules of the jurisdiction, a new trial may occur if:
The Fifth Amendment to the United States Constitution addresses criminal procedure and other aspects of the Constitution. It was ratified, along with nine other articles, in 1791 as part of the Bill of Rights. The Fifth Amendment applies to every level of the government, including the federal, state, and local levels, in regard to a US citizen or resident of the US. The Supreme Court furthered the protections of this amendment through the Due Process Clause of the Fourteenth Amendment.
Holmes v. United States, 391 U.S. 936 (1968), was a case in which the Supreme Court of the United States denied a petition for writ of certiorari to a Jehovah's Witnesses minister who asked the Court to decide whether a draft of men into the Armed Forces in times of peace is constitutionally permissible. The minister argued that, in the absence of a declaration of war, a draft was not authorized and was equivalent to involuntary servitude.
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.
Jury nullification in the United States has its origins in colonial America under British law. In the United States, jury nullification occurs when a jury in a criminal case reaches a verdict contrary to the weight of evidence, sometimes because of a disagreement with the relevant law. The American jury draws its power of nullification from its right to render a general verdict in criminal trials, the inability of criminal courts to direct a verdict no matter how strong the evidence, the Fifth Amendment's Double Jeopardy Clause, which prohibits the appeal of an acquittal, and the fact that jurors cannot be punished for the verdict they return.
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:
Chambers v. Maroney, 399 U.S. 42 (1970), was a United States Supreme Court case in which the Court applied the Carroll doctrine in a case with a significant factual difference—the search took place after the vehicle was moved to the stationhouse. The search was thus delayed and did not take place on the highway as in Carroll. After a gas station robbery, a vehicle fitting the description of the robbers' car was stopped. Inside were people wearing clothing matching the description of that worn by the robbers. They were arrested, and the car was taken to the police station where it was later searched.
There are three types of juries in the United States: criminal grand juries, criminal petit juries, and civil juries. In the United States Constitution, juries are mentioned in Article Three and the Fifth, the Sixth, and the Seventh Amendments. Juries are not available in courts of American Samoa established pursuant to the Constitution of American Samoa.
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.
The United States Constitution contains several provisions regarding the law of criminal procedure.
Gillette v. United States, 401 U.S. 437 (1971), is a decision from the Supreme Court of the United States, adding constraints on the terms of conscientious objection resulting from draftees in the Selective Service.
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.
National Coalition for Men v. Selective Service System was a court case, decided in the United States District Court for the Southern District of Texas on February 22, 2019, that declared that requiring men but not women to register for the draft for military service in the United States was unconstitutional. The ruling did not specify which actions the government must take to resolve the conflict with the constitution. The ruling was appealed to the Fifth Circuit.
