opinion: EX PARTE GEORGE.
  No. 375.
  Decided November 13, 1962.
  Arthur J. Mandell for petitioner.
  Tom M. Davis for respondent.
  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 issue area of the Court's decision. Determine the issue area on the basis of the Court's own statements as to what the case is about. Focus on the subject matter of the controversy rather than its legal basis. In specifying the issue in a legacy case, choose the one that best accords with what today's Court would consider it to be. Choose among the following issue areas: "Criminal Procedure" encompasses the rights of persons accused of crime, except for the due process rights of prisoners. "Civil rights" includes non-First Amendment freedom cases which pertain to classifications based on race (including American Indians), age, indigency, voting, residency, military or handicapped status, gender, and alienage. "First Amendment encompasses the scope of this constitutional provision, but do note that it need not involve the interpretation and application of a provision of the First Amendment. For example, if the case only construe a precedent, or the reviewability of a claim based on the First Amendment, or the scope of an administrative rule or regulation that impacts the exercise of First Amendment freedoms. "Due process" is limited to non-criminal guarantees. "Privacy" concerns libel, comity, abortion, contraceptives, right to die, and Freedom of Information Act and related federal or state statutes or regulations. "Attorneys" includes attorneys' compensation and licenses, along with trhose of governmental officials and employees. "Unions" encompass those issues involving labor union activity. "Economic activity" is largely commercial and business related; it includes tort actions and employee actions vis-a-vis employers. "Judicial power" concerns the exercise of the judiciary's own power. "Federalism" pertains to conflicts and other relationships between the federal government and the states, except for those between the federal and state courts. "Federal taxation" concerns the Internal Revenue Code and related statutes. "Private law" relates to disputes between private persons involving real and personal property, contracts, evidence, civil procedure, torts, wills and trusts, and commercial transactions. Prior to the passage of the Judges' Bill of 1925 much of the Court's cases concerned such issues. Use "Miscellaneous" for legislative veto and executive authority vis-a-vis congress or the states.
