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:
RAY, CHAIRMAN OF THE STATE DEMOCRATIC EXECUTIVE COMMITTEE OF ALABAMA, v. BLAIR.
No. 649.
Argued March 31, 1952.
Decided April 3, 1952.
Marx Leva and Harold M. Cook argued the cause for petitioner. With them on the brief were James J. May-field, George A. LeMaistre and Louis F. Oberdorjer.

Per Curiam.
In this proceeding, an Alabama circuit court entered an order directing petitioner to certify to the Secretary of State of Alabama the name of respondent as a candidate for nomination for Presidential and Vice-Presidential elector in the primary election of the Democratic Party to be held on May 6, 1952. The Alabama Supreme Court affirmed on the single ground that the order was compelled by Article II, Section 1 and the Twelfth Amendment of the United States Constitution.
Petitioner applied to this Court for a stay of the judgments and mandates of the Alabama courts and filed a petition for writ of certiorari to review the judgment of the Alabama Supreme Court. On March 24, 1952, we granted certiorari and ordered the judgments and mandates of the courts below stayed pending further consideration and disposition of the case by this Court. The case was assigned for argument on the stay as well as the merits on March 31, 1952. 343 U. S. 901.
The question raised in this case has been thoroughly briefed and argued. The Court has fully considered the question and has reached its conclusion. It now announces its decision and enters its judgment in advance of the preparation of a full opinion which, when prepared, will be filed with the Clerk. [See post, p. 214.]
The Court holds that Article II, Section 1 and the Twelfth Amendment of the Constitution do not compel issuance of the order and judgment entered below.
The judgment below is reversed. The mandate of this Court is directed to issue forthwith.
Reversed.
