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:
BOSTIC v. UNITED STATES
No. 5250.
Argued April 21, 1971
Decided May 24, 1971
Thomas C. Binkley argued the cause for petitioner. With him on the brief was Philip M. Carden.
Beatrice Rosenberg argued the cause for the United States. With her on the brief were Solicitor General Griswold, Assistant Attorney General Wilson, and Jerome M. Feit.
Per Curiam.
We granted the writ of certiorari in this case to consider whether the Court of Appeals for the Sixth Circuit had erred in holding that the petitioner had properly been convicted of conspiracy to commit murder in order to avoid apprehension for the robbery of a federally insured bank. The Court of Appeals purported to uphold a conviction for this offense, though there was no evidence that the petitioner knew of the plan to commit murder, and he had been confined in prison for several months prior to the date the murder was committed. The memorandum for the United States in opposition to the granting of the writ urged that the petitioner was “responsible for the actions of his co-conspirators in killing one member of the group/’ and as to this issue, relied on the opinion of the Court of Appeals.
It now appears that these statements in the opinion of the Court of Appeals and in the memorandum of the United States were erroneous, and that the facts are not as we believed them to be at the time we granted the writ. The record shows that the petitioner was neither charged with nor convicted of the offense of conspiracy to commit murder. The conspiracy count on which the petitioner was convicted did not include any charge of conspiracy to murder. Indeed, in his closing argument to the jury the prosecutor stated that the petitioner had left the conspiracy prior to the murder, when he was returned to the penitentiary.
Inasmuch as our grant of the writ of certiorari in this case was predicated on the mistaken representation that the petitioner had been convicted of the offense of conspiracy to commit murder, we now dismiss the writ as improvidently granted.
It is so ordered.
400 U. S. 991.
424 F. 2d 951. The opinion recites that the conspiracy count on which the petitioner was convicted “alleged a conspiracy to rob federally insured banks with dangerous weapons and to commit murder to avoid apprehension for same.” 424 F. 2d, at 953. The court went on to say, “As to Bostic, although he had been returned to the penitentiary sometime before Ferguson’s murder, there is no evidence that he had renounced or withdrawn from the conspiracy.” 424 F. 2d, at 964.
