  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 This statute was repealed by the Oklahoma Legislature on May 26, 1951, Okla.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 type of decision made by the court among the following: Consider "opinion of the court (orally argued)" if the court decided the case by a signed opinion and the case was orally argued. For the 1791-1945 terms, the case need not be orally argued, but a justice must be listed as delivering the opinion of the Court. Consider "per curiam (no oral argument)" if the court decided the case with an opinion but without hearing oral arguments. For the 1791-1945 terms, the Court (or reporter) need not use the term "per curiam" but rather "The Court [said],""By the Court," or "By direction of the Court." Consider "decrees" in the infrequent type of decisions where the justices will typically appoint a special master to take testimony and render a report, the bulk of which generally becomes the Court's decision. This type of decision usually arises under the Court's original jurisdiction and involves state boundary disputes. Consider "equally divided vote" for cases decided by an equally divided vote, for example when a justice fails to participate in a case or when the Court has a vacancy. Consider "per curiam (orally argued)" if no individual justice's name appears as author of the Court's opinion and the case was orally argued. Consider "judgment of the Court (orally argued)" for formally decided cases (decided the case by a signed opinion) where less than a majority of the participating justices agree with the opinion produced by the justice assigned to write the Court's opinion.
