opinion: 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offenses committed by members of the conspiracy before petitioners had joined the conspiracy or after they had withdrawn from it.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for substantive offenses committed by members of the conspiracy before that individual had joined or after he had withdrawn from the conspiracy; and second, he concedes that in this case some of the convictions for the substantive offenses must be reversed because they are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.
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the ideological "direction" of the decision ("liberal", "conservative", or "unspecifiable"). Use "unspecifiable" if the issue does not lend itself to a liberal or conservative description (e.g., a boundary dispute between two states, real property, wills and estates), or because no convention exists as to which is the liberal side and which is the conservative side (e.g., the legislative veto). Specification of the ideological direction comports with conventional usage. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. In interstate relations and private law issues, consider unspecifiable in all cases.
