What follows is an opinion from the Supreme Court of the United States. Your task is to identify the disposition of the case, that is, the treatment the Supreme Court accorded the court whose decision it reviewed. The information relevant to this variable may be found near the end of the summary that begins on the title page of each case, or preferably at the very end of the opinion of the Court. For cases in which the Court granted a motion to dismiss, consider "petition denied or appeal dismissed". There is "no disposition" if the Court denied a motion to dismiss.

Per Curiam.
By its terms, the Longshoremen’s and Harbor Workers’ Compensation Act does not apply “if recovery for the disability or death through workmen’s compensation proceedings may . . . validly be provided by State law.” § 3, 44 Stat. 1426, 33 U. S. C. § 903 (a) (emphasis supplied). In Davis v. Department of Labor, 317 U. S. 249, we recognized that in some cases it was impossible to predict in advance of trial whether a worker’s injury occurred in an operation which, although maritime in nature, was so “local” as to allow state compensation laws validly to apply under the limitations of Southern Pacific Co. v. Jensen, 244 U. S. 205. As to cases within this “twilight zone,” Davis, in effect, gave an injured waterfront employee an election to recover compensation under either the Longshoremen’s Act or the Workmen’s Compensation Law of the State in which the injury occurred. It seems plain enough that petitioner’s injury occurred in the “twilight zone,” and that recovery for it “through workmen’s compensation proceedings,” could have been, and in fact was, validly “provided by State law” — the Oregon Workmen’s Compensation Act. Ore. Rev. Stat. §§ 656.002-656.990. Therefore, the Longshoremen’s Act did not bar petitioner’s claim under state law. But since his employer had elected to reject them the automatic compensation provisions of the Oregon Workmen’s Compensation Act did not apply to the claim. Section 656.024 of that law provides, however, that when an employer has elected to reject the Act’s automatic compensation provisions his injured employee may maintain in the courts a negligence action for damages. Of course, the employee could not do this if the case were not within the “twilight zone,” for then the Longshoremen’s Act would provide the exclusive remedy. Since this case is within the “twilight zone,” it follows from what we held in Davis that nothing in the Longshoremen’s Act or the United States Constitution prevents recovery.
