delivered the opinion of the court.
This wаs a proceeding under a New Jersey statute, c. 95, Laws 1911, against a commori carrier by railroad, engaged in both interstate аnd intrastate commerce, to obtain compensation for the death of one of its employees. The employee was in charge of a switch engine in the carrier’s extensive yard at Croxton, New Jersey, and, was switching freight cars about in the yard, еspecially to and from a transfer station. The cars usually contained package freight and many were moved in the course of a day’s work. In some the freight was interstate, .in others intrastate and in still others it was of both classes. This was true of the cars movеd on the day in question. In concluding his work for that day the employee took his engine to the place where it was to remain for the bight and started to leave the yard. His route lay across some of the tracks and while passing over one he was struck by an engine and received injuries from which he soon died. No causal negligence was alleged or proved and both parties аssumed there was none. In these circumstances the trial judge, while not doubting that the fatal injury occurred in the course of the deсeased’s employment, held that he was not then employed in interstate commerce and that compensation should be made under the "state statute to the widow. A judgment in her favor was entered, but was reversed by the Supreme Court of the State, which concluded that the deceased’s employment at the time of the injury was in interstate commerce and that the case was controlled by the- Employers’ Liability Act *172 of Congress, which makes negligence the test of the carrier’s liability or obligation. That judgment was in turn reversed by the Court of Errors and Appeals, which, although assuming “that the conclusion of the Supreme Court as to the charactеr” of the deceased’s employment at the time of the injury “was justified by the facts proved,” .regarded the federal act as withоut bearing, because affording no remedy and imposing no liability in the absence of causal negligence. 88 N. J. L. 619.
The questions presented for decision are these: First, ■whether the federal act is regulative of the carrier’s liability or obligation in every instancе of the injury or death of one of its employees in interstate commerce, or only in those instances where there is causal negligence for which the carrier is responsible. Second, whether the facts proved sustain the conclusion that the dеceased was employed in interstate commerce at the time of the injury. Third, whether by reason of the state statute the сarrier became bound contractually to make compensation in this instance, even though it came within the federal act.
The first question is fully considered in New York Central R. R. Co. v. Winfield, the opinion in which has been just announced, ante, 147, and it suffices here to say that, for the reasons there given, we are of opinion that the federal act proceeds upon the principle which regards negligence as the basis of the duty to make compensation and excludes the existence of such a duty in the absence of negligence, and that Congress intended the act to be as comprehensive of those instances in which it Excludes liability as of those in which liability is imposed. It establishes a rule or regulation which is intended to operate uniformly in all the States, as respects interstate commerce, and in that field it is both paramount and exclusive.
The second question must be given an affirmative an
*173
swer. In leaving the carrier’s yard at the close of his day’s work the deceased was but discharging a duty of his employment. See
North Carolina R. R. Co.
v.
Zachary,
The third question requires some notice of the New Jersey statute. It consists of two parts. One conforms to the principle which regards negligence as the basis of liability and excludes liability in the absence of negligence. In its details, however, thаt part differs materially from the federal act. The other conforms to a different principle which rejects negligencе as a basis of liability and requires compensation to be made by the employer wherever the injury or death of the employee is an incident of the service in which he is employed. This part is described as "elective” and is not to be applied unlеss the employer and the' employee shall have agreed, expressly or impliedly, to be bound thereby and to surrender "their rights to any other method, form or amount of compensation or determination thereof.” Respecting the mode of manifesting suсh an agreement or the contrary, it is provided that every contract of hiring "shall be presumed to have been made” with refеrence to this part of the statute and, unless the contract or a notice from one party to the other contain "an express statement in writing” to the contrary, it "shall be presumed” that the parties "have agreed to be bound” by this part of the statute. There was no express agreement in this instance and there is no *174 basis for regarding the carrier as in any way bound by this part of the statute, save as it provides that an agreement to be bound by it shall be presumed in the absence of a declaration to the contrary. But such a presumption cannot be indulged here, and this for the reason that by the federal act the entire subject, аs respects carriers by railroad and their employees in interstate commerce, was taken without the reach of state laws. It is beyond the power of any State to interfere with the operation of that act, either by putting the carriers and their employees to an election between its provisions and those of a state statute or by imputing such an election tо them by means of a statutory presumption. The third question therefore must be answered in the negative.
It follows that the Court of Errors and Appeals erred in failing to give controlling effect to the federal act.
Judgment reversed.
