What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
UNITED STATES, AS OWNER OF THE CHRISTOPHER GALE, v. NIELSON et al., TRADING AS DAUNTLESS TOWING LINE.
No. 210.
Argued March 1, 1955.
Decided May 16, 1955.
Ralph S. Spritzer argued the cause for the United States. With him on the brief were Solicitor General SobelojJ, Assistant Attorney General Burger and Samuel D. Slade.
Anthony V. Lynch, Jr. argued the cause and filed a brief for respondents.
Mr. Justice Black
delivered the opinion of the Court.
The respondent, Dauntless Towing Line, contracted to use two of its tugs in assisting the United States, petitioner here, move its steamship Christopher Gale from Hoboken to a Brooklyn pier. The Gale was to move under its own propelling power under guidance of one of respondent’s tugboat captains or some other licensed pilot. The contract further provided that a tugboat captain or pilot going on board would become the “servant of the owners of the vessel assisted in respect to the giving of orders to any of the tugs furnished to or engaged in the assisting service and in respect to the handling of such vessel, and neither those furnishing the tugs and/or pilot nor the tugs, their owners, agents, or charterers shall be liable for any damage resulting therefrom.” One of the respondent’s tug captains went aboard the government vessel to pilot it in connection with the moving operation. The two tugs of respondent were at the time fastened to the Gale by lines to help guide its movements. One of the tugs was crushed between the Gale and a pier while attempting to carry out a maneuver under orders of the tug captain piloting the Gale.
The respondent brought this suit in admiralty to recover damages from the United States alleging that damages to the tug were caused by negligent pilotage orders of the tug captain while temporarily acting as “servant” of the Gale. After hearings the District Court found that the damages were caused by the pilot’s negligence “in persisting in his attempt to enter the slip after he knew or should have known that he could not overcome the force of the wind and tide and keep the Christopher Gale from sagging down on Pier 1.” On this finding the District Court entered a decree requiring the United States to pay respondent for damages brought about by this negligence. This decree was entered over the Government’s contention that the contract was invalid if construed as exempting respondent from liability for its own servant’s negligence. 112 F. Supp. 730. Agreeing with the District Court’s reasoning and decree, the Court of Appeals affirmed. 209 F. 2d 958. We granted certio-rari to consider the meaning and validity of the pilotage clause, 348 U. S. 811, and at the same time granted cer-tiorari in two other cases, today decided, which involve validity of contracts exempting towers from liability for negligent towage. Bisso v. Inland Waterways Corp., ante, p. 85; Boston Metals Co. v. The Winding Gulf, ante, p. 122.
Sun Oil Co. v. Dalzell Towing Co., 287 U. S. 291, involved the meaning and validity of a pilotage contract substantially the same as the one here. One of Dalzell’s tug captains negligently piloted Sun Oil’s vessel causing the boat to ground and suffer damages. Sun Oil sued Dalzell. The contract exempting Dalzell from liability for pilotage was pleaded as a defense. This Court held that the tug company could validly contract against being “liable for any damage” caused by the negligence of one of its captains in piloting Sun Oil’s vessel and construed the contract there as having that effect. The question in this case, however, is whether the agreement of the ship being piloted to release the tug company from being “liable for any damage resulting” from negligent pilotage not only relieves the tug company from liability for damage, but allows it affirmatively to collect damages for injury to its own tug due to negligent pilotage by one of its tug captains.
An agreement that one shall not be liable for negligence of a third person cannot easily be read as an agreement that one is entitled to collect damages for negligence of that third person. And there is no reason to stretch contractual language to force payment of damages under circumstances like these. ' A person supplying his own employees for use by another in a common undertaking cannot usually collect damages because of negligent work by the employee supplied. Clear contractual language might justify imposition of such liability. But the contractual language here does not meet such a test and we do not construe it as authorizing respondent to recover damages from petitioner.
Reversed.
