opinion: Per Curiam.
  The petition for a writ of certiorari is granted.
  The respondent, a shipowner, sought indemnity from the petitioner, a stevedoring company, for damages the shipowner had paid to an employee of the stevedore who was injured while working aboard the respondent’s ship. See Albanese v. N. V. Nederl. Amerik Stoomv. Maats., 382 U. S. 283 (1965). A jury found that the stevedoring company had fulfilled its duty of workmanlike service and, accordingly, that no indemnity was due. See Ryan Stevedoring Co. v. Pan-Atlantic S. S. Corp., 350 U. S. 124 (1956). The Court of Appeals reversed this verdict and held, as a matter of law, that the stevedore had not taken reasonable action to avert the injury. 392 P. 2d 763 (1968).
  The cause of the longshoreman’s injury was carbon monoxide inhalation that occurred as he and other longshoremen were using gasoline-powered vehicles to move cargo in the ship’s lower hold. The shipowner contends that the stevedore’s hatch boss acted unreasonably. When longshoremen complained about the lack of ventilation in the hold, the hatch boss informed one of , the ship’s officers that his men would walk off the job unless the officer turned on the ship’s ventilating system. The officer told the men to continue working and promised to activate the ventilating system, which was within the shipowner’s exclusive control and which was concededly adequate to ventilate the hold. When, less than 10 minutes later, the hatch boss realized that the ventilating system had not been turned on, he ordered the men from the hold. The injured longshoreman collapsed as he was ascending a ladder to leave.
  The Court of Appeals said that the hatch boss should have ceased work when he first learned that the ship’s ventilating system was not operating, despite the officer’s promise to turn on the system. Alternatively, he should have used the stevedore’s blowers, which had been left on the pier, to ventilate the hold. The jury, however, in response to a special interrogatory, found that the stevedore had acted reasonably in continuing to work for a brief period in reliance on the officer’s promise. We cannot agree with the Court of Appeals that the stevedore acted unreasonably as a matter of law. Under the Seventh Amendment, that issue should have been left to the jury’s determination. Any other ruling would be inconsistent with this Court’s decision in Atlantic & Gulf Stevedores, Inc. v. Ellerman Lines, Ltd., 369 U. S. 355 (1962).
  The judgment of the Court of Appeals is
  Reversed.
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.
