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:
MOON v. MARYLAND
No. 267.
Argued April 22, 1970
Decided June 8, 1970
Robert Anthony Jacques argued the cause and filed a brief for petitioner.
Edward F. Borgerding, Assistant Attorney General of Maryland, argued the cause for respondent. With him on the brief was Francis B. Burch, Attorney General.
Per Curiam.
“When at the behest of the defendant a criminal conviction has been set aside and a new trial ordered, to what extent does the Constitution limit the imposition of a harsher sentence after conviction upon retrial?” This was the question the Court dealt with last Term in North Carolina v. Pearce, 395 U. S. 711. We held in that case that there exists no absolute constitutional bar to the imposition of a harsher sentence upon retrial, but that due process “requires that vindictiveness against a defendant for having successfully attacked his first conviction must play no part in the sentence he receives after a new trial.” Id., at 725. “In order to assure the absence of such a motivation,” we held that “whenever a judge imposes a more severe sentence upon a defendant after a new trial, the reasons for his doing so must affirmatively appear. Those reasons must be based upon objective information concerning identifiable conduct on the part of the defendant occurring after the time of the original sentencing proceeding.” Id., at 726. The Pearce case was decided on June 23, 1969.
In the present case the petitioner was found guilty of armed robbery by a Maryland jury and sentenced by the trial judge to 12 years’ imprisonment. The conviction was set aside on appeal by the Maryland Court of Appeals. At a second trial for the same offense in 1966 the petitioner was again convicted, and this time the trial judge imposed a sentence of 20 years’ imprisonment, less full credit for time served under the original sentence. This second conviction was affirmed on appeal. 250 Md. 468, 243 A. 2d 564. We granted certiorari, 395 U. S. 975, requesting counsel to brief and argue the question of the retroactivity of North Carolina v. Pearce, supra.
The facts that have emerged since the grant of cer-tiorari impel us to dismiss the writ as improvidently granted. As an appendix to its brief, the respondent has filed an affidavit of the judge who presided at the second trial, setting out in detail the reasons he imposed the 20-year prison sentence. Those reasons clearly include “objective information concerning identifiable conduct on the part of the defendant occurring after the time of the original sentencing proceeding.” But the dispositive development is that counsel for the petitioner has now made clear that there is no claim in this case that the due process standard of Pearce was violated. As counsel forthrightly stated in the course of oral argument, “I have never contended that Judge Pugh was vindictive.”
Accordingly, the writ is dismissed as improvidently granted.
Mr. Justice Black concurs in the result.
Mr. Justice Harlan would reverse the judgment below based on his separate opinions in Desist v. United States, 394 U. S. 244, 256, and in North Carolina v. Pearce, 395 U. S. 711, 744.
Mr. Justice Marshall took no part in the decision of this case.
