Majority — Murphy J.
delivered the opinion of the Court.
The right of jury trial in civil cases at common law is a basic and fundamental feature of our system of federal jurisprudence which is protected by the Seventh Amendment. A right so fundamental and sacred to the citizen,
Petitioner’s testimony[3] is the complete answer to the question whether the case should have been taken from
1 41 Stat. 988 , 1007, 46 U. S. C. § 688 .
2 The complaint set forth two causes of action — the first for personal injuries, and the second for maintenance and cure. Respondent moved to dismiss only the first cause of action. At the same time, in settlement of the second cause of action, respondent offered to consent to judgment for loss of wages from the time of the accident until petitioner returned to work. This offer was refused by petitioner’s counsel and the second cause was thereupon dismissed. The Circuit Court of Appeals, sua sponte, directed that judgment be entered on the second cause of action for petitioner, in the amount admitted to be due from respondent. That judgment is not in issue here. Only the first cause of action, that for personal injuries, survives for our consideration.
3 Petitioner was the sole witness in his own behalf. The trial court did not allow an opinion witness, called for the purpose of establishing the best type of wrench for the work petitioner was doing at the time of the accident, to testify.
The Jones Act, in addition to giving injured seamen the right to trial by jury in actions arising under the Act, also incorporates “all statutes of the United States modifying or extending the common-law right or remedy in cases of personal injury to railway employees.” Among such statutes is 45 U. S. C. § 51 , which provides in part that a carrier is liable for “injury or death ... by reason of any defect or insufficiency, due to its [the carrier’s] negligence, in its cars, engines, appliances, machinery, track, roadbed, works, boats, wharves, or other equipment.”
Although proof of negligence is an essential to recovery under the Jones Act, Kunschman v. United States, 54 F. 2d 987 ; cf. Beadle v. Spencer, 298 U. S. 124 , 128, contributory negligence and assumption of risk are not available defenses. The admiralty doctrine of comparative negligence applies. Socony-Vacuum Co. v. Smith, 305 U. S. 424 . The salient points of petitioner’s testimony, summarized above, made a sufficient showing to allow the jury to consider the issue of respondent’s negligence. The wrench petitioner was using had become defective for the purpose for which it was designed. After discovering that defect, petitioner made three requests to the proper person, the chief engineer, for a new wrench. The
The simple tool doctrine, used by the courts below to bolster their belief that the evidence was insufficient, does not affect our conclusion. In the first place, the contrariety of opinion as to the reasons for and the scope of the simple tool doctrine, and the uncertainty of its application,[4] suggest that it should not apply to cases arising under
4 See 3 Labatt, Master and Servant (2d ed.), pp.. 2476-2484.
5 Compare McCarthy v. Palmer, 113 F. 2d 721 , with Spain v. Powell, 90 F. 2d 580 .
6 If the doctrine is but a phase of assumption of risk or contributory negligence, as has been suggested (see Labatt, op. cit., pp. 2479, 2480, 2484), it is manifestly not applicable to actions under the Jones Act, for those common-law affirmative defenses are not available in such actions. Socony-Vacuum Co. v. Smith, 305 U. S. 424 . And, if the scope of the doctrine is that a master is under no duty to furnish reasonably safe and suitable simple tools (see Allen Gravel Co. v. Yarbrough, 133 Miss. 652 , 98 So. 117 ; Middleton v. National Box Co., 38 F. 2d 89 ), the doctrine is hardly compatible with the scheme of the Jones Act fixing liability on a master for injuries caused by defects and insufficiencies in his appliances due to his negligence.
Since there must be a new trial, we deem it appropriate to state that, in our opinion, no reversible error was committed when the trial court refused to allow opinion testimony as to the best type of tool for the work.[8] Respondent’s duty was not to supply the best tools, but only tools which were reasonably safe and suitable. Cf. The Tawmie, 80 F. 2d 792 ; The Cricket, 71 F. 2d 61 .
The judgment is reversed and the cause remanded to the District Court for further proceedings in conformity with this opinion.
Reversed.
Mr. Justice Frankfurter and Mr. Justice Jackson concur in the result.
