JUSTICE BLACKMUN delivered the opinion of the Court.
Stroud v. United States, 251 U.S. 15 (1919), concerned a defendant who was convicted of first-degree murder and sentenced
to life imprisonment, and who then obtained, upon confession of error by the Solicitor General, a reversal of his conviction and a new trial. This Court, by a unanimous vote in that case, held that the Double Jeopardy Clause of the Fifth Amendment*fn1 did not bar the imposition of the death penalty when Stroud at his new trial was again convicted.
The issue in the present case is whether the reasoning of Stroud is also to apply under a system where a jury's sentencing decision is made at a bifurcated proceeding's second stage at which the prosecution has the burden of proving certain elements beyond a reasonable doubt before the death penalty may be imposed.
Missouri law provides two, and only two, possible sentences for a defendant convicted of capital murder:*fn2 (a) death, or (b) life imprisonment without eligibility for probation or parole for 50 years. Mo. Rev. Stat. § 565.008.1 (1978).*fn3
Like most death penalty legislation enacted after this Court's decision in Furman v. Georgia, 408 U.S. 238 (1972),
the Missouri statutes contain substantive standards to guide the discretion of the sentencer. The statutes also afford procedural safeguards to the convicted defendant. Section 565.006 provides that the trial court shall conduct a separate presentence hearing for the defendant who is convicted by a jury of capital murder.*fn4 The hearing must be held before
the same jury*fn5 that found the defendant guilty, and "additional evidence in extenuation, mitigation, and aggravation of punishment" shall be heard. "Only such evidence in aggravation as the prosecution has made known to the defendant prior to his trial shall be admissible." The jury must consider whether the evidence shows that there exist any of the 10*fn6 aggravating circumstances or the 7 mitigating circumstances specified by the statute, see §§ 565.012.2 and 565.012.3; whether any other mitigating or aggravating circumstances authorized by law exist; whether any aggravating circumstances that do exist are sufficient to warrant the imposition of the death penalty; and whether any mitigating circumstances that exist outweigh the aggravating circumstances. § 565.012.1. A jury that imposes the death penalty must designate in writing the aggravating circumstance or circumstances that it finds beyond a reasonable doubt. § 565.012.4. It also must be convinced beyond a reasonable doubt that any aggravating circumstance or circumstances that it finds to exist are sufficient to warrant the imposition of the death penalty. Missouri Approved Instructions -- Criminal (MAI-Cr) § 15.42 (1979). A Missouri jury is instructed that it is not compelled to impose the death
penalty, even if it decides that a sufficient aggravating circumstance or circumstances exist and that it or they are not outweighed by any mitigating circumstance or circumstances. MAI-Cr. § 15.46. A jury's decision to impose the death penalty must be unanimous. If the jury is unable to agree, the defendant receives the alternative sentence of life imprisonment described above. § 565.006.2; MAI-Cr. § 15.48.
In December 1977, petitioner Robert Bullington was indicted in St. Louis County, Mo., for capital murder and other crimes arising out of the abduction of a young woman and her subsequent death by drowning.*fn7
The Circuit Court of St. Louis County granted petitioner's pretrial motion for a change of venue to Jackson County in the western part of the State. The prosecution, by letter, informed the defense that the State would seek the death penalty if the jury convicted the defendant of capital murder. App. 12. The letter-notice stated that the prosecution would present evidence of two aggravating circumstances specified by the statute: that "[the] offense was committed by a person . . . who has a substantial history of serious assaultive criminal convictions," § 565.012.2 (1), and that "[the] offense was outrageously or wantonly vile, horrible or inhuman in that it involved torture, or depravity of mind," § 565.012.2 (7).
At the guilt-or-innocence phase of petitioner's trial, the jury returned a verdict of guilty of capital murder. App. 21. On the following day, the trial court proceeded to hold the presentence hearing required by § 565.006.2. Evidence submitted by the prosecution was received. None was offered by the defense. After argument by counsel, instructions from the judge, and deliberation, the jury returned its
additional verdict fixing petitioner's punishment not at death, but at imprisonment for life without eligibility for probation or parole for 50 years. App. 27.
Petitioner then moved, on various grounds, for judgment of acquittal or in the alternative for a new trial. While that motion was pending, Duren v. Missouri, 439 U.S. 357 (1979), was decided. In that case this Court held that Missouri's constitutional and statutory provisions allowing women to claim automatic exemption from jury service deprived a defendant of his Sixth and Fourteenth Amendments right to a jury drawn from a fair cross-section of the community. The trial court overruled petitioner's motion for acquittal but, relying upon Duren, granted his motion for a new trial. App. 44.
Soon thereafter, the prosecution served and filed a formal "Notice of Evidence in Aggravation," stating that it intended again to seek the death penalty. The notice specified the same aggravating circumstances the State sought to prove at the first trial, see also Tr. of Oral Arg. 36, and asserted that it would introduce the evidence that was previously disclosed to defense counsel. App. 45-46. The defense moved to strike the notice, id., at 47, arguing that the Double Jeopardy Clause of the Fifth Amendment (as made applicable to the States through the Fourteenth Amendment, Benton v. Maryland, 395 U.S. 784, 794 (1969)) barred the imposition of the penalty of death when the first jury had declined to impose the death sentence.
The trial court announced that it would grant that motion and would not permit the State to seek the death penalty. Before the court issued a formal order to this effect, the prosecution sought a writ of prohibition or mandamus from the Missouri Court of Appeals for the Western District. After granting a temporary "stop order," App. 56, the Court of Appeals without opinion denied the State's request and dissolved the stop order. Id., at 57. The Supreme Court of Missouri, however, granted the prosecution's motion for
transfer of the case to that court and issued a preliminary writ of prohibition. After argument, the court, sitting en banc and by a divided vote, sustained the State's position and made the writ absolute. State ex rel. Westfall v. Mason, 594 S. W. 2d 908 (1980). It held that neither the Double Jeopardy Clause, nor the Eighth Amendment, nor the Due Process Clause barred the imposition of the death penalty upon petitioner at his new trial, and that allowing the prosecution to seek capital ...
