Obergefell v. Hodges, 576 U.S. 644 (2015), is a landmark decision of the Supreme Court of the United States which ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment of the Constitution. The 5–4 ruling requires all fifty states, the District of Columbia, and the Insular Areas to perform and recognize the marriages of same-sex couples on the same terms and conditions as the marriages of opposite-sex couples, with all the accompanying rights and responsibilities. Prior to Obergefell, same-sex marriage had already been established by statute, court ruling, or voter initiative in thirty-six states, the District of Columbia, and Guam.
Davis v. Ayala, 576 U.S. 257 (2015), was a case in which the Supreme Court of the United States upheld a death sentence of a Hispanic defendant despite the fact that all Blacks and Hispanics were rejected from the jury during the defendant's trial. The case involved a habeas corpus petition submitted by Hector Ayala, who was arrested and tried in the late 1980s for the alleged murder of three individuals during an attempted robbery of an automobile body shop in San Diego, California in April 1985. At trial, the prosecution used peremptory challenges to strike all Black and Hispanic jurors who were available for jury service. The trial court judge allowed the prosecution to explain the basis for the peremptory challenges outside the presence of Ayala's counsel, "so as not to disclose trial strategy". Ayala was ultimately sentenced to death, but he filed several appeals challenging the constitutionality of the trial court's decision to exclude his counsel from the hearings.
Kansas v. Carr, 577 U.S. ___ (2016), was a case in which the Supreme Court of the United States clarified several procedures for sentencing defendants in capital cases. Specifically, the Court held that judges are not required to affirmatively instruct juries about the burden of proof for establishing mitigating evidence, and that joint trials of capital defendants "are often preferable when the joined defendants’ criminal conduct arises out of a single chain of events". This case included the last majority opinion written by Justice Antonin Scalia before his death in February 2016.
Luis v. United States, 578 U.S. ___ (2016), was a case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution prohibits the pre-trial restraint of assets needed to retain a defendant's counsel of choice when those assets have not been used in conjunction with criminal activity.
Ocasio v. United States, 578 U.S. ___ (2016), was a United States Supreme Court case in which the Court clarified whether the Hobbs Act's definition of conspiracy to commit extortion only includes attempts to acquire property from someone who is not a member of the conspiracy. The case arose when Samuel Ocasio, a former Baltimore, Maryland police officer, was indicted for participating in a kickback scheme with an automobile repair shop where officers would refer drivers of damaged vehicles to the shop in exchange for cash payments. Ocasio argued that he should not be found guilty of conspiring to commit extortion because the only property that was exchanged in the scheme was transferred from one member of the conspiracy to another, and an individual cannot be found guilty of conspiring to extort a co-conspirator.
Foster v. Chatman, 578 U.S. ___ (2016), was a United States Supreme Court case in which the Court held that the state law doctrine of res judicata does not preclude a Batson challenge against peremptory challenges if new evidence has emerged. The Court held the state courts' Batson analysis was subject to federal jurisdiction because "[w]hen application of a state law bar 'depends on a federal constitutional ruling, the state-law prong of the court’s holding is not independent of federal law, and our jurisdiction is not precluded,'" under Ake v. Oklahoma.
Bravo-Fernandez v. United States, 580 U.S. ___ (2016), was a case in which the Supreme Court of the United States clarified the application of the Fifth Amendment's Double Jeopardy Clause to cases in which a jury returns irreconcilable verdicts that convict a defendant on one count and acquit a defendant on another count when both counts rely upon the same ultimate fact.
Shaw v. United States, 580 U.S. ___ (2016), was a United States Supreme Court case that clarified the application of the federal bank fraud statute to cases where a defendant intends to only defraud a customer of the bank, rather than the bank itself.
Lightfoot v. Cendant Mortgage Corp., 580 U.S. ___ (2017), was a United States Supreme Court case that clarified whether Fannie Mae can be sued in state courts. In a unanimous opinion written by Justice Sonia Sotomayor, the Court held that plaintiffs may file lawsuits against Fannie Mae in any state or federal court that is "already endowed with subject-matter jurisdiction over the suit."
Bell v. Cone, 535 U.S. 685 (2002), was a Supreme Court of the United States case that upheld a death sentence despite the defendant's argument that he should not be sentenced to death because he was suffering from drug-induced psychosis when he committed the crimes. Cone also argued that he was denied effective assistance of counsel because his attorney failed to present sufficient mitigating evidence during the sentencing phase of his trial and that his attorney inappropriately waived his final argument during the sentencing phase. In an 8–1 opinion written by Chief Justice William Rehnquist, the United States Supreme Court denied Cone's petition for a writ of habeas corpus. The Court held that the actions taken by Cone's attorney during the sentencing phase were "tactical decisions" and that the state courts that denied Cone's appeals did not unreasonably apply clearly established law. Justice John Paul Stevens wrote a dissenting opinion in which he argued that Cone was denied effective assistance of counsel because his attorney failed to "subject the prosecution's case to meaningful adversarial testing."
Packingham v. North Carolina, 582 U.S. ___ (2017), is a case in which the Supreme Court of the United States held that a North Carolina statute that prohibited registered sex offenders from using social media websites is unconstitutional because it violates the First Amendment to the U.S. Constitution, which protects the freedom of speech.
Peña-Rodriguez v. Colorado, 580 U.S. ___ (2017), was a United States Supreme Court decision holding that the Sixth Amendment requires a racial bias exception to the no-impeachment rule. According to two jurors, a third juror made a number of biased statements about the defendant's Mexican ethnicity, stating, "I think he did it because he’s Mexican and Mexican men take whatever they want." In a 5–3 vote, the Court held that, notwithstanding a state evidentiary rule, the trial court must be permitted to consider the two jurors' testimony.
Manuel v. Joliet, 580 U.S. ___ (2017), was a case in which the United States Supreme Court held that a criminal defendant may bring a claim under the Fourth Amendment of the United States Constitution to challenge pretrial confinement. In a 6-2 majority opinion written by Justice Elena Kagan, the Court stated that "the Fourth Amendment governs a claim for unlawful pretrial detention even beyond the start of legal process". This decision reversed and remanded the judgment of the Seventh Circuit Court of Appeals. Justice Clarence Thomas wrote a dissenting opinion. Justice Thomas also joined a dissenting opinion by Justice Samuel Alito.
Life Technologies Corp. v. Promega Corp., 580 U.S. ___ (2017), was a case in which the United States Supreme Court clarified the application of the Patent Act of 1952 to the sale of components of patented inventions in foreign markets. In an opinion written by Associate Justice Sonia Sotomayor, the Court held that the sale of a "single component" in a foreign market "does not constitute a substantial portion of the components that can give rise to liability under [the Patent Act of 1952]." Justice Samuel Alito wrote an opinion concurring in part and concurring in the judgment, in which he was joined Justice Clarence Thomas. Chief Justice John Roberts took no part in the decision of the case.
Bethune-Hill v. Virginia State Bd. of Elections, 580 U.S. ___ (2017), was a case in which the United States Supreme Court evaluated whether Virginia's legislature – the Virginia General Assembly – violated the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution by considering racial demographics when drawing the boundaries of twelve of the state's legislative districts.
Beckles v. United States, 580 U.S. ___ (2017), was a case in which the United States Supreme Court evaluated whether the residual clause in the United States Advisory Sentencing Guidelines was unconstitutionally vague.
Cone v. Bell, 556 U.S. 449 (2009), was a case in which the United States Supreme Court held that a defendant was entitled to a hearing to determine whether prosecutors in his 1982 death penalty trial violated his right to due process by withholding exculpatory evidence. The defendant, Gary Cone, filed a petition for postconviction relief from a 1982 death sentence in which he argued that prosecutors violated his rights to due process under the Fourteenth Amendment by withholding police reports and witness statements that potentially could have shown that his drug addiction affected his behavior. In an opinion written by Justice John Paul Stevens, the Supreme Court held that Cone was entitled to a hearing to determine whether the prosecution's failure to disclose exculpatory evidence violated Cone's right to due process; the Court noted that "the quantity and the quality of the suppressed evidence lends support to Cone’s position at trial that he habitually used excessive amounts of drugs, that his addiction affected his behavior during his crime spree". In 2016, Gary Cone died from natural causes while still sitting on Tennessee's death row.
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.
Garza v. Idaho, 586 U.S. ___, 139 S. Ct. 738 (2019), was a case in which the United States Supreme Court held that the presumption of prejudice for Sixth Amendment purposes applies regardless of whether a defendant has waived the right to appeal.
Kimmelman v. Morrison, 477 U.S. 365 (1986), was a decision of the U.S. Supreme Court that clarified the relationship of the right to effective assistance of counsel under the Sixth Amendment to other constitutional rights in criminal procedure. In this case, evidence against the defendant was probably seized illegally, violating the Fourth Amendment, but he lost the chance to argue that point due to his lawyer's ineffectiveness. The prosecution argued that the defendant's attempt to make a Sixth Amendment argument via a habeas corpus petition was really a way to sneak his Fourth Amendment argument in through the back door. The Court unanimously disagreed, and held that the Fourth Amendment issue and the Sixth Amendment issue represented different constitutional values, and had different requirements for prevailing in court, and therefore were to be treated separately by rules of procedure. Therefore, the habeas corpus petition could go forward. In its opinion, the Court also gave guidance on how to apply its decisions in Stone v. Powell and Strickland v. Washington.
