  These two appeals challenge the constitutionality of Okla. Stat., 1941 (Cum. Supp. 1949), Tit. 52, §§ 286.1-286.17, providing for unitized management of common sources of supply of oil and gas in Oklahoma. This statute was repealed by the Oklahoma Legislature on May 26, 1951, Okla. Laws 1951, c. 3a, § 16, p. 142, and we ordered the causes continued in order to determine the effect of this repeal on the matters raised in these appeals. 342 U. S. 35 (1951). After being advised by the Supreme Court of Oklahoma that this repeal had no effect on these causes, we noted probable jurisdiction and heard argument.
  Appellants contend that this statute and an order issued thereunder by the Oklahoma Corporation Commission impair their contractual rights in violation of U. S. Const., Art. I, § 10, and amount to a denial of the Due Process and Equal Protection Clauses of the Fourteenth Amendment. Specifically, appellants argue that the statute is an unreasonable exercise of the State’s police power and an unreasonable delegation of legislative and judicial power to private groups. In addition, appellants maintain that the statute is too vague and indefinite to furnish the Commission with any reasonable guide for the issuance of orders approving unitization plans, and that the evidence does not support the Commission’s findings of fact.
  In the light of our previous decisions, appellants have failed to raise any substantial federal questions and the appeals are therefore dismissed. Cities Service Gas Co. v. Peerless Oil & Gas Co., 340 U. S. 179 (1950); Railroad Commission of Texas v. Rowan & Nichols Oil Co., 311 U. S. 570 (1941); Railroad Commission of Texas v. Rowan & Nichols Oil Co., 310 U.

instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to identify the federal agency involved in the administrative action that occurred prior to the onset of litigation. If the administrative action occurred in a state agency, respond "State Agency". Do not code the name of the state. The administrative activity may involve an administrative official as well as that of an agency. If two federal agencies are mentioned, consider the one whose action more directly bears on the dispute;otherwise the agency that acted more recently. If a state and federal agency are mentioned, consider the federal agency. Pay particular attention to 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.
