Cullen v. Pinholster

United States Supreme Court
131 S. Ct. 1388 (2011)


Facts

Scott Lynn Pinholster (defendant) and two accomplices attempted burglary and killed two men who caught them in the act. Harry Brainard and Wilbur Dettmar were appointed by the California trial court to defend Pinholster. Pinholster was convicted of first-degree murder. Prior to the penalty phase of the trial, Brainard and Dettmar sought to exclude introduction of aggravating evidence that would support the death penalty. They argued that the prosecution had not provided notice of the evidence to be introduced and that the defense counsel was therefore unprepared to mitigate such evidence. The court found that Pinholster had in fact received notice and denied the defense’s motion. During the penalty phase, the prosecution brought eight witnesses. The defense only produced Pinholster’s mother. Although the defense had questioned a psychiatrist, Dr. John Stalberg, about Pinholster’s mental issues, they failed to produce a psychiatrist at the penalty phase. Pinholster was given the death penalty. The California Supreme Court affirmed. After three attempts, Pinholster was granted habeas relief by the Federal District Court on grounds that Pinholster had been denied effective counsel during the penalty phase of the trial. Specifically, Pinholster had argued that Brainard and Dettmar had failed to produce mitigating evidence regarding his mental disorders, and had submitted additional evidence to the District Court in support of his claims. The Court of Appeals for the Ninth Circuit affirmed the District Court’s decision. The State appealed on grounds that, under the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), Pinholster should not have been allowed to present additional evidence not before the state court that adjudicated the claim on its merits.
