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:
FOWLER v. WILKINSON, WARDEN.
No. 620.
Argued April 30, 1957.
Decided June 3, 1957.
Leon S. Epstein argued the cause for petitioner. With him on the brief was R. Monroe Schwartz.
Ralph S. Spritzer argued the cause for respondent. With him on the brief were Solicitor General Rankin, Assistant Attorney General Olney, Beatrice Rosenberg and James W. Booth.
Mr. Justice Clark
delivered the opinion of the Court.
The factual background and the question presented in this case are the same as in Jackson v. Taylor, ante, p. 569, decided today. The case reaches us from the Court of Appeals for the Fifth Circuit, 234 F. 2d 615, which had reversed the District Court. We granted certiorari, 352 U. S. 940.
There are additional reasons to those in Jackson v. Taylor advanced for reversal in this case. Fowler contends that the 20-year sentence is arbitrarily severe, even though within the statutory maximum, citing United States v. Voorhees, 4 U. S. C. M. A. 509, 16 C. M. R. 83 (1954). But as we said in Burns v. Wilson, 346 U. S. 137 (1953), this Court exerts “no supervisory power over the courts which enforce [military law]; the rights of men in the armed forces must perforce be conditioned to meet certain overriding demands of discipline and duty, and the civil courts are not the agencies which must determine the precise balance to be struck in this adjustment. The Framers expressly entrusted that task to Congress.” Id., at 140. If there is injustice in the sentence imposed it is for the Executive to correct, for since the board of review has authority to act, we have no jurisdiction to interfere with the exercise of its discretion. That power is placed by the Congress in the hands of those entrusted with the administration of military justice, or if clemency is in order, the Executive. It may be that the board’s judgment was harsh or that the military’s highest court should have intervened as it did in the Voorhees case, but we have no jurisdiction in that regard. As long ago as 1902 this Court recognized that it was a “salutary rule that the sentences of courts martial, when affirmed by the military tribunal of last resort, cannot be revised by the civil courts save only when void because of an absolute want of power, and not merely voidable because of the defective exercise of power possessed.” Carter v. McClaughry, 183 U. S. 365, 401.
We note that petitioner’s reliance on Voorhees’ case is misplaced when he cites it as apposite to the problem here presented. While the Court of Military Appeals held there that the board should have ordered a rehearing, the rehearing was to include a reconsideration of the finding of guilt as well as the sentence. Though, as Judge Lati-mer indicates in his opinion, the board of review had the power to approve the sentence, dismissal from the service, such approval was found by that court to be an abuse of the discretion placed in the board under the particular circumstances of the case. We, of course, do not sit to pass on the exercise of discretion by the military authorities. Judge Latimer further indicated the Court of Military Appeals’ recognition of the power of the board of review to affirm such parts, or amount of a sentence, as it finds correct in fact and law. The case, then, instead of supporting petitioner’s position, indicates authority for the power of the board to modify the sentence. See United States v. Bigger, 2 U. S. C. M. A. 297, 8 C. M. R. 97 (1953).
The argument that the adjustment of the sentence by the board deprives the petitioner of two appeals likewise is without merit. He contends that if the resentencing were done by a court-martial he would have a review of that resentencing by the convening authority as well as the board of review. But Congress did not intend any such result. The accused has already had his day before the court-martial and the convening authority. It is not for us to say that the procedure established by Congress is unwise. There are no constitutional questions before us. We have determined that the board of review had jurisdiction to modify the sentence. Our inquiry cannot be extended beyond that question.
For these reasons, and those stated in Jackson v. Taylor, ante, p. 569, the judgment is
Affirmed.
The Chief Justice, Mr. Justice Black, Mr. Justice Douglas, and Mr. Justice Brennan dissent for the reasons stated in the dissenting opinion of Mr. Justice Brennan in No. 619, Jackson v. Taylor, ante, p. 581.
