Mr. Justice Douglas
delivered the opinion of the Court.
Petitioner brought this suit under the Jones Act, 46 U. S. C.- § 688, and recovered judgment after a jury trial. He was employed as mate on respondent’s barge. On the day prior to the injury the barge came to respondent’s repair yard to have a cargo pump fixed. At this repair yard respondent maintained' a covered lighter, known as the Winisook, which was used as a work barge. Its inshore side was connected with the dock by a plank runway. Between the Winisook and the dock was a raft used for chipping, painting, and welding on such barges as might need that service. The barge on which petitioner worked was not at this time being serviced by the raft. But the raft had been used in repair work on thé barge at other times and now needed new decking.
The barge was moored to adjoin the open water side of the Winisook, the crew of the barge using a catwalk around the sides of the Winisook whenever they left or boarded the barge. The morning after the barge was moored, petitioner’s supervisor ordered him to lay some decking on the raft, as petitioner had experience as a carpenter. Petitioner accordingly prepared to go to work on this new job assignment. As he was standing on the catwalk, preparatory to starting his work, releasing a line on the raft to permit him to maneuver it into place so he could board it, the catwalk gave way, causing the injury. The Court of Appeals reversed the judgment for - petitioner. 263 F. 2d 147. We granted the petition for certiorari because that decision seemed to be out of line with the authorities. 359 U. S. 952.
In O’Donnell v. Great Lakes Co., 318 U. S. 36, a seaman was allowed to recover under the Jones Act even though he was injured on shore. The seaman was a deckhand. The ship was discharging her cargo through a conduit that was connected at its outer end to a land pipe by means of a gasket. • The seaman in question' was ordered by the master to go ashore to assist in repairing the gasket. While so engaged, he was injured by reason of the negligence of a fellow employee. We held that the words “in the course of his employment”, as used in the Jones Act were not restricted to injuries occurring on navigable waters, that they were broadly used by Congress in support of “all .the constitutional power it possessed,” id., at 39, and that it was constitutionally permissible for Congress to supplement the remedy of maintenance and cure by extending a right of recovery in trial by jury to a seaman injured “while in the service of his vessel by negligence.” Id., at 43.
The test, as the O’Donnell case holds, is not whether the injury occurred on navigable waters, for that had been applied by the lower court, id., at 38, which we reversed. Rather it is whether the seaman was injured by negligence while “in the course of his employment.”
The injured party must of course have “status as a member of the vessel” for it is seamen, not others who may work on the vessel (Swanson v. Marra Bros., 328 U. S. 1, 4), to whom Congress extended the protection of the Jones Act. Niee questions often arise concerning the status of particular workmen and whether their duties give them the status óf “seamen” as that word is used in the Act. Desper v. Starved Rock Ferry Co., 342 U. S. 187. And see Gianfala v. Texas Co., 350 U. S. 879, reversing 222 F. 2d 382; Senko v. LaCrosse Dredging Corp., 352 U. S. 370; Butler v. Whiteman, 356 U. S. 271. The court below apparently thought that at the moment petitioner was injured he was not a “seaman”; and that conclusion apparently turned on its view that to be such he had to be engaged at the time of the injury in work which was in furtherance of the navigation of the vessel. The court, indeed, held it error not to have given instructions to that effect.
At times the work done by an employee will be crucial in determining what his status is for purposes of recovery. South Chicago Co. v. Bassett, 309 U. S. 251, 260; Swanson v. Marra Bros., supra; Desper v. Starved Rock Ferry Co., supra; Pennsylvania R. Co. v. O’Rourke, 344 U. S. 334; Grimes v. Raymond Concrete Pile Co., 356 U. S. 252; Butler v. Whiteman, supra. Those cases, however, are not relevant to our present''problem since the question whether petitioner’s duties on the.raft assignment were of the . type to bring one not otherwise a member of a ship’s crew within the scope of the Act is not presented in this case. Here we start with an employee who had the status of mate. The issue is whether petitioner, a mate and therefore a “seaman,” was injured “in the course of his employment.” We conclude that he was.
The fact that the injury did not occur on the vessel is not controlling, as Senko v. LaCrosse Dredging Corp., supra, 373, holds. A “seaman” may often be sent off ship to perform duties of his employment. O’Donnell v. Great Lakes Co., supra. In Marceau v. Great Lakes Transit Corp., 146 F. 2d 416, a ship’s cook was allowed to recover under the Jones Act when, pursuant to duty, he was returning to the ship and was injured on the dock while approaching a ladder used as ingress to the vessel.
We held that a seaman who was injured on the dock while departing from the ship on shore leave was in the service óf the vessel and was entitled to recover for maintenance and curé in Aguilar v. Standard Oil Co., 318 U. S. 724. It was there recognized that a seaman is as much in the service of his ship when boarding it on first reporting for duty, quitting it on being discharged, or going to and from the ship while on shore leave, as he is while on board at high sea. Id., at 736-737. We also held that a seaman injured in a dance hall while on shore leave was in the service of his ship in Warren v. United States, 340 U. S. 523, 529. These two cases were not brought under the Jones Act but involved maintenance and cure. Yet they make clear that the scope of a seaman’s employment or the activities which are related to the furtherance of the vessel are not measured by the standard's applied to land-based employment relationships. They also supply relevant guides to the meaning of the term “course of employment” .'under the Act since it is the equivalent of the “service of the ship” formula used in maintenance and cure cases. See Gilmore and Black, The Law of Admiralty, p. 284, And see O’Donnell v. Great Lakes, Co., supra, at 43; Marceau v. Great Lakes Transit Corp., supra.
Petitioner in the present case was ordered by a superior to perform some carpentry work on a raft which lay between the lighter and the dock. Petitioner was injured, as we have said, while on- the catwalk attempting to move the’raft into position for boarding. ■ The raft was used to facilitate chipping, painting and welding on respondent’s vessels. Cf. Grant Smith-Porter Co. v. Rohde, 257 U. S. 469. New decking was to be installed on the raft. The fact that the raft was not presently being used, to repair respondent’s barge is in our view immaterial. Petitioner- was acting “in the course of his employment” at the time of the injury, for at that moment he was doing the work of his employer pursuant to his employer’s orders. No more is required by the Jones Act, as the O’Donnell case indicates, petitioner being a seaman who was injured as' a consequence of the negligence of his employer.
The judgment of the Court of Appeals is reversed and the judgment of the District Court is reinstated.
So ordered.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. 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. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
