Hill v. McDonough, 547 U.S. 573 (2006), was a United States Supreme Court case challenging the use of lethal injection as a form of execution in the state of Florida. The Court ruled unanimously that a challenge to the method of execution as violating the Eighth Amendment to the United States Constitution properly raised a claim under 42 U.S.C. § 1983, which provides a cause of action for civil rights violations, rather than under the habeas corpus provisions. Accordingly, that the prisoner had previously sought habeas relief could not bar the present challenge.

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.
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.
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."
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.
Wilson v. Sellers, 584 U.S. ___ (2018), is a United States Supreme Court case concerning whether a federal court sitting in a habeas corpus proceeding should "look through" a summary ruling to review the last reasoned decision by a state court.
Plumhoff v. Rickard, 572 U.S. 765 (2014), is a United States Supreme Court case involving the use of force by police officers during high-speed car chases. After first holding that it had jurisdiction to hear the case, the Court held that the conduct of the police officers involved in the case did not violate the Fourth Amendment to the U.S. Constitution, which prohibits unreasonable searches and seizures.
Department of Homeland Security v. Thuraissigiam, 591 U.S. ___ (2020), was a United States Supreme Court case involving whether the Illegal Immigration Reform and Immigrant Responsibility Act of 1996, which limits habeas corpus judicial review of the decisions of immigration officers, violates the Suspension Clause of Article One of the U.S. Constitution. In the 7–2 opinion, the Court ruled that the law does not violate the Suspension Clause.
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.
