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 these cases, the United States Court of Appeals for the First Circuit upheld the District Court’s August 7, 1981, orders enjoining the Boston Police and Fire Departments from laying off policemen and firefighters in a manner that would reduce the percentage of minority officers below the level obtaining at the commencement of layoffs in July 1981. 679 F. 2d 965 (1982). These orders had the effect of partially superseding the operation of the State’s statutory last-hired, first-fired scheme for civil service layoffs, Mass. Gen. Laws Ann., ch. 31, § 39 (West 1979). Following the Court of Appeals’ decision, Massachusetts enacted legislation providing the city of Boston with new revenues, requiring reinstatement of all police and firefighters laid off during the reductions in force, securing these personnel against future layoffs for fiscal reasons, and requiring the maintenance of minimum staffing levels in the Police and Fire Departments through June 30, 1983. See 1982 Mass. Acts, ch. 190, § 25. In light of these changed circumstances, we vacate the judgment of the Court of Appeals and remand for consideration of mootness in light of 1982 Mass. Acts, ch. 190, § 25.
It is so ordered.
