Task: sc_decisiontype

What follows is an opinion from the Supreme Court of the United States. Your task is to identify the type of decision made by the court among the following: Consider "opinion of the court (orally argued)" if the court decided the case by a signed opinion and the case was orally argued. For the 1791-1945 terms, the case need not be orally argued, but a justice must be listed as delivering the opinion of the Court. Consider "per curiam (no oral argument)" if the court decided the case with an opinion but without hearing oral arguments. For the 1791-1945 terms, the Court (or reporter) need not use the term "per curiam" but rather "The Court [said],""By the Court," or "By direction of the Court." Consider "decrees" in the infrequent type of decisions where the justices will typically appoint a special master to take testimony and render a report, the bulk of which generally becomes the Court's decision. This type of decision usually arises under the Court's original jurisdiction and involves state boundary disputes. Consider "equally divided vote" for cases decided by an equally divided vote, for example when a justice fails to participate in a case or when the Court has a vacancy. Consider "per curiam (orally argued)" if no individual justice's name appears as author of the Court's opinion and the case was orally argued. Consider "judgment of the Court (orally argued)" for formally decided cases (decided the case by a signed opinion) where less than a majority of the participating justices agree with the opinion produced by the justice assigned to write the Court's opinion.

Per Curiam.
In 1982, an Arizona jury convicted respondent Robert Douglas Smith of first-degree murder, kidnaping, and sexual assault. He was sentenced to death. The convictions and sentence were affirmed on direct appeal, and Smith’s state petitions for posteonviction relief proved unsuccessful. Smith then filed a petition for a writ of habeas corpus in the United States District Court for the District of Arizona. In none of these proceedings did Smith argue that he was mentally retarded or that his mental retardation made him ineligible for the death penalty. Smith had, however, presented evidence in mitigation during the sentencing phase of his trial showing that he had low intelligence.
The District Court denied Smith’s petition for habeas corpus in 1996. Following several rounds of appeals, remands, and petitions for certiorari to this Court (including one successful petition by the State, see Stewart v. Smith, 536 U. S. 856 (2002) (per curiam)), and after we had issued our decision in Atkins v. Virginia, 536 U. S. 304 (2002), the case returned to the Ninth Circuit. Shortly thereafter, Smith asserted in briefing that he is mentally retarded and cannot, under Atkins, be executed. The Ninth Circuit ordered suspension of all federal habeas proceedings and directed Smith to “institute proceedings in the proper trial court of Arizona to determine whether the state is prohibited from executing [Smith] in accordance with Atkins.” App. to Pet. for Cert. A-2. The court further ordered that the issue whether Smith is mentally retarded must “be determined ... by a jury trial unless the right to a jury is waived by the parties.” Ibid.
The State’s petition for certiorari is granted, the judgment of the Court of Appeals is vacated, and the case is remanded. The Ninth Circuit erred in commanding the Arizona courts to conduct a jury trial to resolve Smith’s mental retardation claim. Atkins stated in clear terms that “ ‘we leave to the State[s] the task of developing appropriate ways to enforce the constitutional restriction upon [their] execution of sentences.’ ” 536 U. S., at 317 (quoting Ford v. Wainwright, 477 U. S. 399, 416-417 (1986); modifications in original). States, including Arizona, have responded to that challenge by adopting their own measures for adjudicating claims of mental retardation. While those measures might, in their application, be subject to constitutional challenge, Arizona had not even had a chance to apply its chosen proee-dures when the Ninth Circuit pre-emptively imposed its jury trial condition.
Because the Court of Appeals exceeded its limited authority on habeas review, the judgment below is vacated, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Srmth’s motion to proceed informa pauperis is also granted.
