What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
BELCHER v. STENGEL et al.
No. 75-823.
Argued November 2, 1976
Decided November 30, 1976
Robert A. Bell argued the cause for petitioner. With him on the brief were John L. Francis and Patrick M. McGrath.
John H. Lewis argued the cause and filed a brief for respondents.
Solicitor General Bork, Assistant Attorney General Pottinger, and Walter W. Barnett filed a brief for the United States as amicus curiae urging affirmance.
Michael E. Geltner, Melvin L. Wiilj, Joel M. Gora, Stanley K. Laughlin, and Nelson G. Karl filed a brief for the American Civil Liberties Union et al. as amici curiae.
Per Curiam.
This case grew out of a barroom affray in Columbus, Ohio, in the course of which the petitioner, an off-duty Columbus police officer, shot and killed two people and permanently disabled a third. The injured victim and the representatives of the deceased victims, who are the respondents here, brought an action against the petitioner in a Federal District Court under 42 U. S. C. § 1983. A jury awarded them monetary damages, and the judgment based upon that verdict was affirmed by the United States Court of Appeals for the Sixth Circuit. 522 F. 2d 438.
The petition for certiorari, which we granted on April 5, 1976, 425 U. S. 910, presented a single question:
“Does the fact that an off-duty police officer, out of uniform, is required by police department regulation to carry a weapon at all times, establish that any use of that weapon against the person of another, even though the officer is engaged in private conduct at the time, [is] an act 'under color of law’ within the meaning of 42 U. S. C. § 1983?”
The case having now been fully briefed and orally argued, it appears that the question framed in the petition for certiorari is not in fact presented by the record now before us. For in addition to the said police department regulation, there was evidence before the jury that showed: (1) The petitioner had been awarded workmen’s compensation benefits for the injuries he had received in the affray, on the ground that the injuries had been incurred in the course of his employment; (2) the petitioner, after the affray, had been granted official leave on account of injuries received “in line of duty under circumstances relating to Police duties”; (3) a Board of Inquiry convened to investigate the barroom episode had determined that the petitioner’s “actions were in the line of duty.”
Now that plenary consideration has shed more light on this case than in the nature of things was afforded at the time the petition for certiorari was considered, we have concluded that the writ should be dismissed as improvidently granted. See The Monrosa v. Carbon Black, Inc., 359 U. S. 180, 183-184 (1959).
It is so ordered.
Section 1983 provides:
“Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress.”
At no time during this litigation has the petitioner questioned the respondents’ claim that, if the petitioner was acting “under color of .law,” there was a deprivation of the respondents’ “rights, privileges, or immunities secured by the Constitution and laws” within the meaning of 42 ü. S. C. § 1983.
