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:
HUTTO, ARKANSAS DEPARTMENT OF CORRECTION COMMISSIONER v. ROSS
No. 75-1726.
Decided November 1, 1976
Per Curiam.
In March 1972, in Johnson County, Ark., respondent was charged by information with the crime of embezzlement. With the assistance of counsel, respondent entered into plea negotiations with the prosecuting attorney, and the parties reached an agreement that respondent would enter a plea of guilty on the understanding that the prosecutor would recommend a 15-year prison sentence, with 10 years suspended. Approximately two weeks later, the prosecuting attorney asked respondent’s counsel whether respondent would be willing to make a statement concerning the crimes. Although counsel advised respondent of his Fifth Amendment privilege and informed him that the terms of the negotiated plea bargain were available regardless of his willingness to comply with the prosecuting attorney’s request, the respondent agreed to make a statement confessing to the crime charged. The record discloses that the statement was made under oath in the office of respondent’s counsel, with counsel present, and after respondent had been advised of his rights under Miranda v. Arizona, 384 U. S. 436 (1966).
Respondent subsequently withdrew from the plea bargain, retained new counsel, and demanded a jury trial. The trial court ruled, after hearing evidence outside the presence of the jury, that respondent had confessed voluntarily. The statement was admitted at trial, and respondent was convicted and sentenced to 21 years’ imprisonment. On appeal, the Arkansas Supreme Court affirmed. Ross v. State, 257 Ark. 44, 514 S. W. 2d 409 (1974). This Court denied certiorari. 421 U. S. 931 (1975).
Respondent then filed a petition for a writ of habeas corpus in the United States District Court for the Western District of Arkansas challenging the state court’s finding of voluntariness. 28 U. S. C. § 2254. The District Court held an evidentiary hearing, and on May 23, 1975, denied the petition, agreeing with the state court that the confession was voluntary and therefore admissible. Mobley ex rel. Ross v. Meek, 394 F. Supp. 1219 (1975).
The Court of Appeals for the Eighth Circuit reversed, finding the statement inadmissible because “it . . . was made in connection with an offer to plead guilty and after a [plea] bargain had been agreed upon.” 531 F. 2d 924, 926 (1976). It made no difference, in the court’s view, that the confession was not an express precondition of the plea bargain; the confession became “part and parcel” of the plea bargain because “[the] confession would [not] have been made at the request of the prosecution but for the plea bargain.” Ibid, (emphasis added). Since the plea bargain had not been executed, the court found the confession involuntary and therefore inadmissible.
The only question in this case is whether a confession is per se inadmissible in a criminal trial because it was made subsequent to an agreed upon plea bargain that did not call for such a confession. We conclude that the Court of Appeals erred when it held that any statement made as a result of a plea bargain is inadmissible.
The Court of Appeals reasoned that respondent’s confession was involuntary because it was made “as a result of the plea bargain” and would not have been made “but for the plea bargain.” Id., at 927, 926. But causation in that sense has never been the test of voluntariness. See Brady v. United States, 397 U. S. 742, 749-750 (1970). The test is whether the confession was “ ‘extracted by any sort- of threats or violence, [or] obtained by any direct or implied promises, however slight, [or] by the exertion of any improper influence.’ ” Bram v. United States, 168 U. S. 532, 542-543 (1897); see Brady v. United States, supra, at 753. The existence of the bargain may well have entered into respondent’s decision to give a statement, but counsel made it clear to respondent that he could enforce the terms of the plea bargain whether or not he confessed. The confession thus does not appear to have been the result of “ ‘any direct or implied promises’ ” or any coercion on the part of the prosecution, and was not involuntary. Bram v. United States, supra, at 542-543.
The petition for a writ of certiorari is granted, the judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
Me. Justice Stewaet dissents. Agreeing with the reasoning of the Court of Appeals, he would affirm its judgment.
It is so ordered.
Counsel for respondent testified at the federal habeas corpus hearing that the prosecuting attorney asked for the statement in order to complete his file "as to actually what occurred and how [respondent] took the money and used it.” 1 Record 37.
In response to questions asked by the prosecuting attorney at this meeting, respondent said that his confession was voluntary and that he had not been promised anything in return for making the confession. Mobley ex rel. Ross v. Meek, 394 F. Supp. 1219, 1221-1222 (WD Ark. 1975).
This case does not involve the admissibility at trial of a guilty plea subsequently withdrawn by leave of court. That issue was settled in Kercheval v. United States, 274 U. S. 220 (1927), which held that such pleas could not be used as evidence of guilt at a subsequent trial. Nor does this case involve the admissibility in criminal trials of statements made during the plea negotiation process. See Fed. Rule Crim. Proc. 11 (e) (6); Moulder v. State, 154 Ind. App. 248, 289 N. E. 2d 522 (1972) ; ABA Project on Standards for Criminal Justice, Pleas of Guilty § 3.4 (Approved Draft of 1968),
