In United States law, ineffective assistance of counsel (IAC) is a claim raised by a convicted criminal defendant asserting that the defendant's legal counsel performed so ineffectively that it deprived the defendant of the constitutional right guaranteed by the Assistance of Counsel Clause of the Sixth Amendment to the United States Constitution. Ineffectiveness claims may only be brought where the defendant had the right to counsel, ordinarily during the critical stages of a prosecution.
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.

The Supreme Court of the United States handed down six per curiam opinions during its 2004 term, which began October 4, 2004 and concluded October 3, 2005.
House v. Bell, 547 U.S. 518 (2006), is a United States Supreme Court case challenging the permissibility of new DNA forensic evidence that becomes available post-conviction, in capital punishment appeals when those claims have defaulted pursuant to state law. The Court found that admitting new DNA evidence was in line with Schlup v. Delo (1995), which allows cases to be reopened in light of new evidence.
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.
Schlup v. Delo, 513 U.S. 298 (1995), was a case in which the United States Supreme Court expanded the ability to reopen a case in light of new evidence of innocence.
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.

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.
Townsend v. Sain, 372 U.S. 293 (1963), was a United States Supreme Court case wherein the Court expanded the circumstances in which federal courts should hold evidentiary hearings when presented with petitions for habeas corpus by state prisoners following denial of postconviction relief in state court. The Court held that federal district courts must hold evidentiary hearings if the state court did not resolve all material factual disputes in a full and fair hearing supported by the record.
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 procedurally defaulted Fourth Amendment claim 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.
Shinn v. Ramirez, 596 U.S. 366 (2022), was a case decided by the United States Supreme Court related to the Antiterrorism and Effective Death Penalty Act of 1996. The court held that new evidence that was not in the state court's records, based on ineffective assistance of post-conviction counsel, could not be used in an appeal to a federal court.
Martinez v. Ryan, 566 U.S. 1 (2012), was a United States Supreme Court case about ineffective assistance of counsel claims which allowed a narrow exception to Coleman v. Thompson. Coleman said that inadequate post-conviction counsel is not cause to excuse procedural default for a state habeas claim that was filed late under the state's procedural rules. The Supreme Court may excuse a procedural default if state procedures do not allow at least one "full and fair" opportunity to litigate the constitutional claim. The narrow holding of Martinez excused procedural default caused by attorney error in "initial review collateral proceedings" where state law requires that ineffective assistance claims are raised in post-conviction proceedings and makes no provision for post-conviction counsel.
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 who had instructed his defense counsel not to put on any mitigation case during the sentencing phase of a capital murder trial. 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.
