What follows is an opinion from the Supreme Court of the United States. Your task is to identify the disposition of the case, that is, the treatment the Supreme Court accorded the court whose decision it reviewed. The information relevant to this variable may be found near the end of the summary that begins on the title page of each case, or preferably at the very end of the opinion of the Court. For cases in which the Court granted a motion to dismiss, consider "petition denied or appeal dismissed". There is "no disposition" if the Court denied a motion to dismiss.

Opinion:
SCHMIDT et al., dba SCHMIDT & POLLARD v. OAKLAND UNIFIED SCHOOL DISTRICT et al.
No. 81-1444.
Decided June 21, 1982
Per Curiam.
California Educ. Code Ann. § 39640 (West Supp. 1982) requires school districts to award any contracts for work involving more than $12,000 to the “lowest responsible bidder.” For projects over $100,000, the Oakland School District requires that to be considered responsible, general contractors must use minority-owned businesses for at least 25 percent of the dollar amount of the total bid. Petitioners submitted the low bid for an advertised project but were disqualified under the School District plan as not being responsible. They brought this action claiming damages and asserting that the affirmative-action plan violated not only the Federal Constitution but also state law. The Court of Appeals affirmed a judgment of the District Court upholding the plan on constitutional grounds. 662 F. 2d 550 (1981). Although the Court of Appeals acknowledged that under one of its prior decisions, the plan at issue might be invalid under state law, it declined to decide the state-law question since it was a sensitive matter and petitioners could present it to the state courts.
If the affirmative-action plan is invalid under state law, the Court of Appeals need not have reached the federal constitutional issue. Nevertheless, the Court of Appeals declined to resolve the pendent state-law claim. Under Hagans v. Lavine, 415 U. S. 528, 546 (1974), and Mine Workers v. Gibbs, 383 U. S. 715 (1966), this was an abuse of discretion in the circumstances of this case.
We accordingly grant the petition for certiorari, vacate the judgment of the Court of Appeals, and remand the case for further proceedings consistent with this opinion.
So ordered.
