The Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), Pub. L.Tooltip Public Law 104–132 (text)(PDF), 110 Stat. 1214, enacted April 24, 1996, was introduced to the United States Congress in April 1995 as a Senate Bill. The bill was passed with broad bipartisan support by Congress in response to the bombings of the World Trade Center and Oklahoma City. It was signed into law by President Bill Clinton.
Day v. McDonough, 547 U.S. 198 (2006), is a US Supreme Court case involving the one-year statute of limitations for filing habeas corpus petitions that was established by the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA). In a 5–4 decision, the Court ruled that if the government unintentionally failed to object to the filing of a petition after the AEDPA limitations period has expired, it is not an abuse of discretion for a district court to dismiss sua sponte the petition on that basis.
Carey v. Musladin, 549 U.S. 70 (2006), is a United States Supreme Court case involving the standard for when a federal court can grant habeas corpus relief to overturn a criminal conviction based on the state court's misapplication of established federal law. At issue was whether a criminal defendant's constitutional right to a fair trial was violated when relatives of the alleged victim were permitted to sit in the courtroom as spectators during the trial, wearing buttons that displayed the victim's image.
In United States law, habeas corpus is a recourse challenging the reasons or conditions of a person's confinement under color of law. A petition for habeas corpus is filed with a court that has jurisdiction over the custodian, and if granted, a writ is issued directing the custodian to bring the confined person before the court for examination into those reasons or conditions. The Suspension Clause of the United States Constitution specifically included the English common law procedure in Article One, Section 9, clause 2, which demands that "The privilege of the writ of habeas corpus shall not be suspended, unless when in cases of rebellion or invasion the public safety may require it."
Strickland v. Washington, 466 U.S. 668 (1984), was a landmark Supreme Court case that established the standard for determining when a criminal defendant's Sixth Amendment right to counsel is violated by that counsel's inadequate performance.
Panetti v. Quarterman, 551 U.S. 930 (2007), is a decision by the Supreme Court of the United States, ruling that criminal defendants sentenced to death may not be executed if they do not understand the reason for their imminent execution, and that once the state has set an execution date death-row inmates may litigate their competency to be executed in habeas corpus proceedings. This decision reaffirmed the Court's prior holdings in Ford v. Wainwright, and Stewart v. Martinez-Villareal.
Wiggins v. Smith, 539 U.S. 510 (2003), is a case in which the United States Supreme Court spelled out standards for "effectiveness" in the constitutional right to legal counsel guaranteed by the Sixth Amendment. Previously the court had determined that the Sixth Amendment included the right to "effective assistance" of legal counsel, but it did not specify what constitutes "effective", thus leaving the standards for effectiveness vague. In Wiggins v. Smith, the court set forth the American Bar Association Guidelines for the Appointment and Performance of Defense Counsel in Death Penalty Cases Guideline 11.8.6.(1989), as a specific guideline by which to measure effectiveness and competence of legal counsel.
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.
Premo v. Moore, 562 U.S. 115 (2011), is a United States Supreme Court case involving the right of individuals to federal habeas corpus relief on state-law claims. In a unanimous ruling, the court held that habeas relief may not be granted with respect to any claim that a state-court has found on the merits unless the state-court decision denying relief involves an "unreasonable application" of "clearly established federal law, as determined by" the Court.
The Supreme Court of the United States handed down eight per curiam opinions during its 2014 term, which began October 6, 2014 and concluded October 4, 2015.
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.
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."
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.
Brown v. Davenport, 596 U.S. ___ (2022), was a case decided by the United States Supreme Court. The case concerned whether habeas relief may be granted if the Brecht v. Abrahamson test alone is satisfied, or if the application of Chapman v. California by the state courts was unreasonable because of AEDPA. The court held that federal courts can not grant habeas relief when state courts have already ruled on a prisoner's claim, unless the situation satisfies the test laid out in Brecht v. Abrahamson, and the test laid out in AEDPA.
Howes v. Fields, 565 U.S. 499 (2012), was a decision by the U.S. Supreme Court that an interrogation of a prisoner was not a custodial interrogation per se, and certainly it was not "clearly established federal law" that it was custodial, as would be required by the Antiterrorism and Effective Death Penalty Act (AEDPA). Instead, the Court said, whether the interrogation was custodial depended on the specific circumstances, and moreover, in the particular circumstances of this case, it was not custodial. This decision overturned the rule of the Sixth Circuit, and denied the prisoner's habeas corpus petition.
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.
Martinez v. Ryan, 566 U.S. 1 (2012), was a United States Supreme Court case which considered whether criminal defendants ever have a right to the effective assistance of counsel in collateral state post-conviction proceedings. The Court held that a procedural default will not bar a federal habeas court from hearing ineffective-assistance-of-trial-counsel if there was no counsel or ineffective counsel in an initial-review collateral proceeding.
Cullen v. Pinholster, 563 U.S. 170, is a 2011 United States Supreme Court case concerning evidentiary development in federal habeas corpus proceedings. Oral arguments in the case took place on November 9, 2010, and the Supreme Court issued its decision on April 4, 2011. The Supreme Court held 5–4 that only evidence originally presented before the state court in which the claim was originally adjudicated on the merits could be presented when raising a claim under 28 U.S.C. § 2254(d)(1), and that evidence from a federal habeas court could not be presented in such proceedings. It also held that the convicted murderer Scott Pinholster, the respondent in the case, was not entitled to the habeas relief he had been granted by the United States Court of Appeals for the Ninth Circuit.
Schriro v. Landrigan, 550 U.S. 465 (2007), was a United States Supreme Court case decided on May 14, 2007. In a 5–4 decision written by Justice Clarence Thomas, the Court held that the District Court had not abused its discretion when it refused to grant an evidentiary hearing to convicted murderer Jeffrey Timothy Landrigan. In doing so, the Supreme Court also reversed the prior ruling to the contrary by the en banc United States Court of Appeals for the Ninth Circuit, which had held that Landrigan was entitled to habeas relief on the grounds that he had received ineffective assistance of counsel. The latter court had also held that the District Court's denial of such a hearing to Landrigan amounted to an "unreasonable determination of the facts", which is one of the two circumstances under which the Antiterrorism and Effective Death Penalty Act of 1996 permits the granting of federal habeas relief to state prisoners. The Supreme Court's decision also found that a criminal defendant could waive the right for their lawyer to present mitigating evidence on their behalf, and that such a waiver did not have to be "knowing and intelligent" in order to be valid, even in a capital case.
Williams v. Taylor, 529 U.S. 420 (2000), was a United States Supreme Court case concerning the interpretation of a provision of the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA). The case was argued on February 28, 2000, and decided on April 18, 2000. In a unanimous opinion written by Justice Anthony Kennedy, the Supreme Court held that the provision at issue only bars evidentiary hearings by state prisoners in federal habeas proceedings if "there is lack of diligence, or some greater fault, attributable to the prisoner or his counsel". This case concerned a convicted murderer, Michael Wayne Williams, who was incarcerated at Sussex State Prison in Waverly, Virginia. Confusingly, it was decided on the same day as another case called Williams v. Taylor, which concerned Terry Williams, a different convicted murderer incarcerated at the same prison; both cases named the prison's warden at the time, John B. Taylor, as the respondent.
