The abuse defense is a criminal law defense in which the defendant argues that a prior history of abuse justifies violent retaliation. While the term most often refers to instances of child abuse or sexual assault, it also refers more generally to any attempt by the defense to use a syndrome or societal condition to deflect responsibility away from the defendant. Sometimes the concept is referred to as the abuse excuse, in particular by the critics of the idea that guilty people may use past victimization to diminish the responsibility for their crimes.
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.
In criminal law, the right to counsel means a defendant has a legal right to have the assistance of counsel and, if the defendant cannot afford a lawyer, requires that the government appoint one or pay the defendant's legal expenses. The right to counsel is generally regarded as a constituent of the right to a fair trial. Historically, however, not all countries have always recognized the right to counsel. The right is often included in national constitutions. Of the 194 constitutions currently in force, 153 have language to this effect.

Tennard v. Dretke, 542 U.S. 274 (2004), was a United States Supreme Court case in which the court was asked whether evidence of the defendant's low IQ in a death penalty trial had been adequately presented to the jury for full consideration in the penalty phase of his trial. The Supreme Court held that not considering a defendant's low IQ would breach his Eighth Amendment rights and constitute a cruel and unusual punishment.
Padilla v. Commonwealth of Kentucky, 559 U.S. 356 (2010), is a case in which the United States Supreme Court decided that criminal defense attorneys must advise noncitizen clients about the deportation risks of a guilty plea.

Deck v. Missouri, 544 U.S. 622 (2005), was a United States Supreme Court case that dealt with the constitutionality of shackling a prisoner during the sentencing phase of a trial. In a 7–2 opinion delivered by Justice Breyer, the court held that it is against due process, a right prescribed by the 5th and 14th Amendments, to shackle a defendant in the sentencing portion of a trial unless the shackling relates to a specific defendant and certain state interests.
The Assistance of Counsel Clause of the Sixth Amendment to the United States Constitution provides: "In all criminal prosecutions, the accused shall enjoy the right...to have the Assistance of Counsel for his defence."

In the United States, a public defender is a lawyer appointed by the courts and provided by the state or federal governments to represent and advise those who cannot afford to hire a private attorney. Public defenders are full-time attorneys employed by the state or federal governments. The public defender program is one of several types of criminal legal aid in the United States.
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.
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.
Shinn v. Ramirez, 596 U.S. ___ (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.
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.
