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:
CASE v. NEBRASKA.
No. 843.
Argued April 28, 1965.
Decided May 24, 1965.
Daniel J. Meador, by appointment of the Court, 379 U. S. 995, argued the cause and filed a brief for petitioner.
Melvin Kent Kammerlohr, Assistant Attorney General of Nebraska, argued the cause for respondent. With him on the brief was Clarence A. H. Meyer, Attorney General.
Per Curiam.
Petitioner sought a writ of habeas corpus in the District Court for Lancaster County, Nebraska, alleging that he was unconstitutionally denied the assistance of counsel when he entered a plea of guilty in that court to a charge of burglary. The trial court dismissed the petition without a hearing, and filed no opinion. The Nebraska Supreme Court affirmed. 177 Neb. 404, 129 N. W. 2d 107. The Supreme Court’s opinion recognized that petitioner’s allegations, if true, would establish a violation of the Federal Constitution. 177 Neb., at 410,129 N. W. 2d, at 111. The Supreme Court held, however, that, in Nebraska, “Habeas corpus is not available to discharge a prisoner from a sentence of penal servitude if the court imposing it had jurisdiction of the offense and of the person charged with the crime, and the sentence was within the power of the court.” 177 Neb., at 412, 129 N. W. 2d, at 112. We granted certiorari, 379 U. S. 958, to decide whether the Fourteenth Amendment requires that the States afford state prisoners some adequate corrective process for the hearing and determination of claims of violation of federal constitutional guarantees.
After certiorari was granted, the Nebraska Legislature enacted a statute providing a postconviction procedure. Neb. Leg. Bill 836, Seventy-fifth Session, effective April 12, 1965. On its face, the statute provides for a hearing of petitions such as this one, alleging denial of federal constitutional rights. Therefore, the judgment is vacated and the cause remanded to the Nebraska Supreme Court for reconsideration in light of the supervening statute.
It is so ordered.
