Batson v. Kentucky, 476 U.S. 79 (1986), was a landmark decision of the United States Supreme Court ruling that a prosecutor's use of a peremptory challenge in a criminal case—the dismissal of jurors without stating a valid cause for doing so—may not be used to exclude jurors based solely on their race. The Court ruled that this practice violated the Equal Protection Clause of the Fourteenth Amendment. The case gave rise to the term Batson challenge, an objection to a peremptory challenge based on the standard established by the Supreme Court's decision in this case. Subsequent jurisprudence has resulted in the extension of Batson to civil cases and cases where jurors are excluded on the basis of sex.
Strauder v. West Virginia, 100 U.S. 303 (1880), was a landmark decision of the Supreme Court of the United States about racial discrimination and United States constitutional criminal procedure. Strauder was the first instance where the Supreme Court reversed a state court decision denying a defendant's motion to remove his criminal trial to federal court pursuant to Section 3 of the Civil Rights Act of 1866.
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.
Stromberg v. California, 283 U.S. 359 (1931), was a landmark decision of the Supreme Court of the United States in which the Court held, 7–2, that a California statute banning red flags was unconstitutional because it violated the First and Fourteenth Amendments to the United States Constitution. In the case, Yetta Stromberg was convicted for displaying a red flag daily in the youth camp for children at which she worked, and was charged in accordance with California law. Chief Justice Charles Hughes wrote for the seven-justice majority that the California statute was unconstitutional, and therefore Stromberg's conviction could not stand.
United States v. Ballard, 322 U.S. 78 (1944), was a United States Supreme Court case from the October 1943 term.
McCleskey v. Kemp, 481 U.S. 279 (1987), is a United States Supreme Court case, in which the death sentence of Warren McCleskey for armed robbery and murder was upheld. The Court said the "racially disproportionate impact" in the Georgia death penalty indicated by a comprehensive scientific study was not enough to mitigate a death penalty determination without showing a "racially discriminatory purpose." McCleskey has been described as the "most far-reaching post-Gregg challenge to capital sentencing."
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.
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.
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:
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.
David Christopher Baldus was an American legal scholar. He was the Joseph B. Tye Professor of Law at the University of Iowa. He held the position from 1969 until his death in 2011.

The Supreme Court of the United States handed down nineteen per curiam opinions during its 2009 term, which began on October 5, 2009, and concluded October 3, 2010.
Vasquez v. Hillery, 474 U.S. 254 (1986), is a United States Supreme Court case, which held that a defendant's conviction must be reversed if members of their race were systematically excluded from the grand jury that indicted them, even if they were convicted following an otherwise fair trial.
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.
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.
Flowers v. Mississippi, No. 17–9572, 588 U.S. 284 (2019), is a United States Supreme Court decision regarding the use of peremptory challenges to remove black jurors during a series of Mississippi criminal trials for Curtis Flowers, a black man convicted on murder charges. The Supreme Court held in Batson v. Kentucky that the use of peremptory challenges solely on the basis of race is unconstitutional. This case examined whether the Mississippi Supreme Court erred in how it applied Batson to this case. The Supreme Court ruled that Flowers' case fell under Batson and that the state inappropriately removed most of the potential black jurors during the trials.
Ramos v. Louisiana, 590 U.S. 83 (2020), is 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 criminal trials. See 590 U.S. 83 at 90 (2020) "Wherever we might look to determine what the term “trial by an impartial jury” meant at the time of the Sixth Amendment's adoption—whether it's the common law, state practices in the founding era, or opinions and treatises written soon afterward—the answer is unmistakable. A jury must reach a unanimous verdict in order to convict." 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.
Chapman v. California, 386 U.S. 18 (1967), was a decision by the Supreme Court of the United States that a federal "harmless error" rule must apply, instead of equivalent state rules, for reviewing trials where federally-protected rights had been violated.
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.
