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.
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.
Abrams v. United States, 250 U.S. 616 (1919), was a decision by the Supreme Court of the United States upholding the 1918 Amendment to the Espionage Act of 1917, which made it a criminal offense to urge the curtailment of production of the materials necessary to wage the war against Germany with intent to hinder the progress of the war. The 1918 Amendment is commonly referred to as if it were a separate Act, the Sedition Act of 1918.
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.
United States v. Booker, 543 U.S. 220 (2005), is a United States Supreme Court decision on criminal sentencing. The Court ruled that the Sixth Amendment right to jury trial requires that other than a prior conviction, only facts admitted by a defendant or proved beyond a reasonable doubt to a jury may be used to calculate a sentence exceeding the prescribed statutory maximum sentence, whether the defendant has pleaded guilty or been convicted at trial. The maximum sentence that a judge may impose is based upon the facts admitted by the defendant or proved to a jury beyond a reasonable doubt.
Scheidler v. National Organization for Women, 547 U.S. 9 (2006), was a lengthy and high-profile U.S. legal case interpreting and applying the federal Racketeer Influenced and Corrupt Organizations Act (RICO): a law originally drafted to combat the mafia and organized crime, the Hobbs Act: an anti-extortion law prohibiting interference with commerce by violence or threat of violence, and the Travel Act: a law prohibiting interstate travel in support of racketeering.
The Speech or Debate Clause is a clause in the United States Constitution. The clause states that members of both Houses of Congress
...shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their attendance at the Session of their Respective Houses, and in going to and from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place.
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:
Ashe v. Swenson, 397 U.S. 436 (1970), was a decision by the United States Supreme Court, which held that "when an issue of ultimate fact has once been determined by a valid and final judgment, that issue cannot again be litigated between the same parties in any future lawsuit." The Double Jeopardy Clause prevents a state from relitigating a question already decided in favor of a defendant at a previous trial. Here, the guarantee against double jeopardy enforceable through the Fifth Amendment provided that where the defendant was acquitted of robbing one victim, the government could not prosecute the criminal defendant in a second trial for a different victim in the same robbery.
Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), is a United States Supreme Court case in which the Court held that it was a violation of the Sixth Amendment right of confrontation for a prosecutor to submit a chemical drug test report without the testimony of the person who performed the test. While the court ruled that the then-common practice of submitting these reports without testimony was unconstitutional, it also held that so called "notice-and-demand" statutes are constitutional. A state would not violate the Constitution through a "notice-and-demand" statute by both putting the defendant on notice that the prosecution would submit a chemical drug test report without the testimony of the scientist and also giving the defendant sufficient time to raise an objection.
United States v. Kilbride, 584 F.3d 1240 is a case from the United States Court of Appeals for the Ninth Circuit rejecting an appeal from two individuals convicted of violating the Can Spam Act and US obscenity law. The defendants were appealing convictions on 8 counts from the District Court of Arizona for distributing pornographic spam via email. The second count which the defendants were found guilty of involved the falsification of the "From" field of email headers, which is illegal to do multiple times in commercial settings under 18 USC § 1037(a)(3). The case is particularly notable because of the majority opinion on obscenity, in which Judge Fletcher writes an argument endorsing the use of a national community obscenity standard for the internet.
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 Smith Act trials of Communist Party leaders in New York City from 1949 to 1958 were the result of US federal government prosecutions in the postwar period and during the Cold War between the Soviet Union and the United States. Leaders of the Communist Party of the United States (CPUSA) were accused of violating the Smith Act, a statute that prohibited advocating violent overthrow of the government. The defendants argued that they advocated a peaceful transition to socialism, and that the First Amendment's guarantee of freedom of speech and of association protected their membership in a political party. Appeals from these trials reached the US Supreme Court, which ruled on issues in Dennis v. United States (1951) and Yates v. United States (1957).
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.
Scales v. United States, 367 U.S. 203 (1961), was a 1960 decision of the United States Supreme Court that upheld the conviction of Junius Scales for violating of the Smith Act on the basis on his membership in the Communist Party of the United States (CPUSA).
Ginzburg v. United States, 383 U.S. 463 (1966), was a decision by the United States Supreme Court involving the application of the First Amendment to Federal obscenity laws. One of a trio of cases, Ginzburg was part of the Supreme Court's attempt to refine the definitions of obscenity after the landmark 1957 case Roth v. United States.
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.
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.
