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:
LEVINE v. UNITED STATES.
No. 112.
Decided February 28, 1966.
Nicholas J. Capitano for petitioner in No. 112.
Thomas F. Call for petitioner in No. 125.
Joseph W. Wyatt for petitioner in No. 230.
Sidney M. Dubbin and E. David Rosen for petitioners in No. 234.
Solicitor General Marshall, former Solicitor General Cox, Assistant Attorney General Vinson, Beatrice Rosenberg and Daniel H. Benson for the United States.
Together with No. 125, Roberts v. United States, No. 230, Grene v. United States, and No. 234, Gradsky et al. v. United States, also on petitions for writs of certiorari to the same court.
Per Curiam.
Ten persons were found guilty by a jury on each count of a 10-count indictment. The count predicated on 18 U. S. C. § 371 (1964 ed.) charged all defendants with conspiring to violate § 17 of the Securities Act of 1933, 15 U. S. C. § 77q (a) (1964 ed.), and the Mail Fraud Act, 18 U. S. C. § 1341 (1964 ed.); each of the remaining nine counts charged all defendants with substantive offenses of violating these latter statutes. The Court of Appeals affirmed all the conspiracy convictions; and, with some exception for petitioner Roberts and two other defendants, that court also affirmed the convictions for the substantive offenses. 342 F. 2d 147. Four defendants petitioned for writs of certiorari, and a fifth defendant subsequently moved to be added as a co-petitioner in one of the petitions already filed (No. 234). We grant that motion; and we grant the petitions for writs of certiorari limited to the issue whether petitioners were improperly convicted of substantive offenses committed by members of the conspiracy before petitioners had joined the conspiracy or after they had withdrawn from it. In all other respects the petitions are denied.
In response to specific questions addressed by this Court, the Solicitor General has made a two-pronged concession: First, he concedes that an individual cannot be held criminally liable for substantive offenses committed by members of the conspiracy before that individual had joined or after he had withdrawn from the conspiracy; and second, he concedes that in this case some of the convictions for the substantive offenses must be reversed because they are inconsistent with this principle. On the basis of this concession, and upon consideration of the entire record, we vacate the judgment of the Court of Appeals insofar as it affirms petitioners’ convictions for the substantive offenses. We remand the case to that court with instructions to reverse the convictions the Solicitor General concedes must be reversed, and to determine, in light of the concession, the evidence, the instructions to the jury, and the applicable principles of law, whether in addition to the relief conceded by the Solicitor General petitioners are entitled to further relief regarding the convictions for the substantive offenses.
Vacated and remanded.
Specifically, the Solicitor General concedes that petitioner Levine’s convictions on Counts 1, 3, 4, 5, 6, 7, and 8, and petitioner Grene’s convictions on Counts 1 and 7 must be reversed.
