opinion: 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.
  The judgment is reversed and the cause is remanded to the Supreme Court of Oregon for proceedings not inconsistent with this opinion.
  The Chief Justice and Mr. Justice Frankfurter took no part in the consideration or decision of this case.
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to identify whether administrative action occurred in the context of the case prior to the onset of litigation. The activity may involve an administrative official as well as that of an agency. To determine whether administration action occurred in the context of the case, consider the material which appears in the summary of the case preceding the Court's opinion and, if necessary, those portions of the prevailing opinion headed by a I or II. Action by an agency official is considered to be administrative action except when such an official acts to enforce criminal law. If an agency or agency official "denies" a "request" that action be taken, such denials are considered agency action. Exclude: a "challenge" to an unapplied agency rule, regulation, etc.; a request for an injunction or a declaratory judgment against agency action which, though anticipated, has not yet occurred; a mere request for an agency to take action when there is no evidence that the agency did so; agency or official action to enforce criminal law; the hiring and firing of political appointees or the procedures whereby public officials are appointed to office; attorney general preclearance actions pertaining to voting; filing fees or nominating petitions required for access to the ballot; actions of courts martial; land condemnation suits and quiet title actions instituted in a court; and federally funded private nonprofit organizations.
