opinion: Per Curiam.
  The petition for certiorari is granted. We vacate the judgment of the Supreme Court of Texas setting aside the original writ of habeas corpus issued by it on July 10, 1961, and remand the cause to that court for further proceedings not inconsistent with this opinion.
  American Oil Company was involved in a labor dispute with the National Maritime Union, which represented unlicensed crew members aboard company vessels. The union peacefully picketed a refinery operated by a subsidiary of American that had a valid collective bargaining agreement with the Oil, Chemical and Atomic Workers International Union. Upon findings that the object of the National Maritime Union’s picketing of the refinery was to secure the disregard, breach or violation of the collective bargaining agreement by the refinery workers and their union, in violation of Art. 5154d, § 4, Vernon’s Tex. Rev. Civ. Stat., Ann., the subsidiary-obtained a temporary injunction from the Tenth Judicial District Court of Galveston County against picketing at the refinery. The injunction in express terms bound the petitioner, an official'of the National Maritime Union. Petitioner nevertheless picketed the refinery after publicly announcing his intention so to do, on the ground that he did not believe that the court had jurisdiction to issue the injunction. He was adjudged in contempt.
  The only issue mooted on the habeas corpus proceeding was the jurisdiction of the District Court to issue the injunction. Under Texas law one may not be punished for contempt for violating a temporary injunction, as here, granted by a court having no' jurisdiction of the subject matter. Ex parte Twedell, 158 Tex. 214, 309 S. W. 2d 834; Ex parte Dilley, 160 Tex. 522, 334 S. W. 2d 425. The District Court was without jurisdiction if petitioner’s picketing was arguably prohibited or arguably protected by the National Labor Relations Act. “In the absence of the Board’s clear determination that an activity is neither protected nor prohibited or of compelling precedent applied to essentially undisputed facts, it is not for this Court to decide whether such activities are subject to state jurisdiction.” San Diego Building Trades Council v. Garmon, 359 U. S. 236, 246. The Texas Supreme Court held that petitioner’s conduct was neither arguably prohibited nor arguably protected by the Act. 163 Tex.-, 358 S. W. 2d 590. We disagree. Even assuming, without deciding, that the picketing would not fall within the prohibitions of § 8 (b)(1)(A) or § 8 (b)(4)(i)(B) of the National Labor Relations Act, as amended, we hold, in light of the District Court’s finding that American wholly owns the subsidiary and “directs'and controls all of . . . [its] activities,” that petitioner’s picketing was conduct at least arguably protected by § 7 of the Act.
  Vacated and remanded.
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.
