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:
BEARD v. STAHR, SECRETARY OF THE ARMY, et al.
No. 648.
Decided May 28, 1962.
Frederick Bernays Wiener for appellant.
Solicitor General Cox, Assistant Attorney General Orrick and John G. Laughlin, Jr. for appellees.
Per Curiam.
The judgment of the District Court is vacated and the cause is remanded with directions to dismiss the complaint. The action is premature. The appellant will not be removed from the active list of the Regular Army unless the Secretary of the Army exercises the discretionary authority to remove him conferred by 10 U. S. C. § 3794. The Secretary has not stated that he will so exercise his discretion as to remove appellant. If the Secretary does not remove the appellant it will be unnecessary to pass on the constitutional objections which have been urged. If appellant is removed, the Court is satisfied that adequate procedures for seeking redress will be open to him. Compare Aircraft & Diesel Corp. v. Hirsch, 331 U. S. 752, 772-773. Accordingly, the application for a stay is denied.
The Chief Justice is of the opinion that further consideration of the question of jurisdiction should be postponed to the hearing of the case on the merits and would grant the application for a stay.
Mr. Justice Frankfurter took no part in the decision of this case.
