opinion: Per Curiam.
  In this case the respondent Reggie Hammerstein, by her mother and guardian, commenced a paternity action against the petitioner in the Superior Court of California. Petitioner entered a special appearance in that court, alleging that it had no personal jurisdiction over him, as he was a New York resident. He moved to quash the service upon him in New York on the grounds that any judgment obtained against him in this proceeding would deprive him of due process. The motion to quash was denied. The superior court entered judgment for the respondent.
  Prior to the entry of the judgment, petitioner filed a petition for a writ of prohibition in the District Court of Appeal. This petition was denied without opinion. The California Supreme Court denied his application for a hearing. After judgment, petitioner filed in the California Supreme Court a petition for a writ of certiorari to review the superior court proceedings. The California Supreme Court denied this petition without opinion. We granted certiorari, 340 U. S. 919 (1951).
  Throughout these proceedings, petitioner preserved his federal questions, but since neither of the decisions below was accompanied by an opinion, it is not clear whether the California courts found it necessary to decide any federal question. If their judgments rest upon an adequate state ground, we, of course, will not review those judgments. If the denials of petitioner's applications for review were based upon a determination of the merits of his federal claim, the case will be ripe for our adjudication. In this circumstance, we think it advisable that we adhere to the procedure followed in Herb v. Pitcairn, 324 U. S. 117 (1945).
  We will continue the cause for such period as will enable counsel for the petitioner, with all convenient speed, to apply to the appropriate California courts for certificate or other expression, to show whether the judgments herein rest on adequate and independent state grounds or whether decision of the federal question was necessary to the judgments rendered. Cf. Loftus v. Illinois, 334 U. S. 804 (1948); Indiana ex rel. Anderson v. Brand, 303 U. S. 95 (1938).
  Cause continued.
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.
