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.
Reynolds v. United States, 98 U.S. 145 (1878), was a Supreme Court of the United States case that held that religious duty was not a defense to a criminal indictment. Reynolds was the first Supreme Court opinion to address the First Amendment's protection of religious liberties, impartial juries and the Confrontation Clauses of the Sixth Amendment.
Cheek v. United States, 498 U.S. 192 (1991), was a United States Supreme Court case in which the Court reversed the conviction of John L. Cheek, a tax protester, for willful failure to file tax returns and tax evasion. The Court held that an actual good-faith belief that one is not violating the tax law, based on a misunderstanding caused by the complexity of the tax law, negates willfulness, even if that belief is irrational or unreasonable. The Court also ruled that an actual belief that the tax law is invalid or unconstitutional is not a good faith belief based on a misunderstanding caused by the complexity of the tax law, and is not a defense.
The Supreme Court of the United States handed down sixteen per curiam opinions during its 2005 term, which lasted from October 3, 2005, until October 1, 2006.
Cohen v. Cowles Media Co., 501 U.S. 663 (1991), was a U.S. Supreme Court case holding that the First Amendment freedom of the press does not exempt journalists from generally applicable laws.
Hoyt v. Florida, 368 U.S. 57 (1961), was an appeal by Gwendolyn Hoyt, who had killed her husband and received a jail sentence for second degree murder. Although she had suffered mental and physical abuse in her marriage and showed neurotic, if not psychotic, behavior, a six-man jury deliberated for just 25 minutes before finding her guilty. They sentenced her to 30 years of hard labor. Hoyt claimed that her all-male jury led to discrimination and unfair circumstances during her trial. The decision was subsequently overruled by Taylor v. Louisiana in 1975.
Apodaca v. Oregon, 406 U.S. 404 (1972), was a United States Supreme Court case in which the Court held that state juries may convict a defendant by a less-than-unanimous verdict in a felony criminal case. The four-justice plurality opinion of the court, written by Justice White, affirmed the judgment of the Oregon Court of Appeals and held that there was no constitutional right to a unanimous verdict. Although federal law requires federal juries to reach criminal verdicts unanimously, the Court held Oregon's practice did not violate the Sixth Amendment right to trial by jury and so allowed it to continue. In Johnson v. Louisiana, a case decided on the same day, the Court held that Louisiana's similar practice of allowing criminal convictions by a jury vote of 9–3 did not violate due process or equal protection under the Fourteenth Amendment.
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.
Griffin v. California, 380 U.S. 609 (1965), was a United States Supreme Court case in which the Court ruled, by a 6–2 vote, that it is a violation of a defendant's Fifth Amendment rights for the prosecutor to comment to the jury on the defendant's declining to testify, or for the judge to instruct the jury that such silence is evidence of guilt.
Burch v. Louisiana, 441 U.S. 130 (1979), was a case decided by the United States Supreme Court that invalidated a Louisiana statute allowing a conviction upon a nonunanimous verdict from a jury of six for a petty offense. The statute allowed for conviction if only five jurors agreed, and this was held to be a violation of the Sixth Amendment.
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.
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.
The representation of women on United States juries drastically increased during the last hundred years because of legislation and court rulings. Until the latter part of the twentieth century, women were routinely excluded from jury service. The push for women's jury rights sparked a debate similar to that surrounding the women's suffrage movement. At the time, it permeated the media with arguments for and against. Federal and state court case rulings increased women's participation on juries. Some states allowed women to serve on juries much earlier than others, while also differing on whether women's suffrage also implied women's jury service.
Simmons v. South Carolina, 512 U.S. 154 (1994), is a United States Supreme Court case holding that, where a capital defendant's future dangerousness is at issue, and the only alternative sentence available is life imprisonment without the possibility of parole, the sentencing jury must be informed that the defendant is ineligible for parole.
United States v. Sineneng-Smith, 590 U.S. ___ (2020), was a case of the United States Supreme Court, in which the justices considered the constitutionality of 8 U.S.C. § 1324(a)(1)(A)(iv), a provision of the Immigration and Nationality Act of 1952 that criminalizes encouraging or inducing illegal immigration. The case attracted attention from civil liberties groups and immigration advocates, including the American Civil Liberties Union, the Immigrant Defense Project, and the National Lawyers Guild.
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.
Edwards v. Vannoy, 593 U.S. ___ (2021), was a United States Supreme Court case involving the Court's prior decision in Ramos v. Louisiana, 590 U.S. ___ (2020), which had ruled that jury verdicts in criminal trials must be unanimous under the Sixth Amendment to the U.S. Constitution. The Supreme Court ruled 6–3 that Ramos did not apply retroactively to earlier cases prior to their verdict in Ramos.
Iowa v. Tovar, 541 U.S. 77 (2004), was a unanimous decision of the Supreme Court of the United States that clarified how well-informed a defendant had to be to waive their right to counsel under the Sixth Amendment. The defendant in this case had waived his right to counsel and pled guilty to drunk driving, and then had been convicted of drunk driving twice more, with sentences increasing as his convictions piled up. He argued that the judge in the first case had not explained that multiple drunk driving convictions would lead to more severe sentences, so his waiver of counsel had been invalid. The Supreme Court disagreed, saying that the judge's warnings had been adequate, and the defendants' waiver was "knowing, voluntary, and intelligent."
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.
