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 determine the ideological "direction" of the decision ("liberal", "conservative", or "unspecifiable"). Use "unspecifiable" if the issue does not lend itself to a liberal or conservative description (e.g., a boundary dispute between two states, real property, wills and estates), or because no convention exists as to which is the liberal side and which is the conservative side (e.g., the legislative veto). Specification of the ideological direction comports with conventional usage. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. In interstate relations and private law issues, consider unspecifiable in all cases.
