What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
KAISER STEEL CORP. v. W. S. RANCH CO.
No. 1328.
Decided June 3, 1968.
/. R. Modrall for petitioner.
William R. Federici for respondent.
Boston E. Witt, Attorney General, and F. Harlan Flint, Special Assistant Attorney General, filed a brief for the State of New Mexico on the relation of the New Mexico State Engineer, as amicus curiae, in support of the petition.
Per Curiam.
Respondent brought this diversity suit in the United States District Court for the District of New Mexico, claiming an illegal trespass by petitioner and seeking damages and an injunction. Petitioner admitted the alleged trespass but claimed it was authorized to do this by N. M. Stat. Ann. § 75-1-3 (1953), in order to use water rights it had been granted by the State. Respondent contended that if § 75-1-3 were construed to authorize condemnation of private land to secure water for a private business, the law would violate the New Mexico Constitution, which permits the taking of private property only for “public use.” N. M. Const., Art. II, § 20. The crucial issue thus became the interpretation of the term “public use” in the State Constitution. The District Court held that the property had been taken for a public use, rejecting the suggestion in petitioner’s brief that the action be stayed pending decision of the crucial question by the state courts. The Court of Appeals reversed on the merits, 388 F. 2d 257 (1967), and rejected petitioner’s motion to stay the federal court’s action until the state law issues could be settled in a declaratory judgment suit then pending in the state courts, 388 F. 2d, at 262 (1968) (on petition for rehearing).
The Court of Appeals erred in refusing to stay its hand. The state law issue which is crucial in this case is one of vital concern in the arid State of New Mexico, where water is one of the most valuable natural resources. The issue, moreover, is a truly novel one. The question will eventually have to be resolved by the New Mexico courts, and since a declaratory judgment action is actually pending there, in all likelihood that resolution will be forthcoming soon. Sound judicial administration requires that the parties in this case be given the benefit of the same rule of law which will apply to all other businesses and landowners concerned with the use of this vital state resource.
The writ of certiorari is granted, the judgment of the Court of Appeals is reversed, and the case is remanded with directions that the action be stayed in accordance with the prayer of petitioner. Federal jurisdiction will be retained in the District Court in order to insure a just disposition of this litigation should anything prevent a prompt state court determination.
It is so ordered.
