three protections to the criminal defendant. The first two, which are the most familiar, protect against a second prosecution for the same offense after acquittal, and against a second prosecution for the same offense after conviction. See, e. g., Ohio v. Johnson, 467 U. S. 493, 498 (1984). Neither of these protections against successive prosecutions is involved here. Rather, respondent’s initial conviction and sentence for both felony murder and the underlying felony violated the third aspect of the Double Jeopardy Clause, the protection against “multiple punishments for the same offense” imposed in a single proceeding. See North Carolina v. Pearce, 395 U. S. 711, 717 (1969). The constitutional question in this case is what remedy is required to cure the admitted violation.
The answer turns on the interest that the Double Jeopardy Clause seeks to protect. Our cases establish that in the multiple punishments context, that interest is “limited to ensuring that the total punishment did not exceed that authorized by the legislature.” United States v. Halper, 490 U. S. 435, 450 (1989); see Johnson, supra, at 499; Missouri v. Hunter, 459 U. S. 359, 366-367 (1983). The purpose is to ensure that sentencing courts do not exceed, by the device of multiple punishments, the limits prescribed by the legislative branch of government, in which lies the substantive power to define crimes and prescribe punishments. See, e. g., Johnson, supra, at 499. In this case, respondent’s conviction of both felony murder and attempted robbery gave rise to a double jeopardy claim only because the Missouri Legislature did not intend to allow conviction and punishment for both felony murder and the underlying felony. E. g., Hunter, supra, at 368; see also Morgan, supra, at 1; Olds, supra, at 510 (construing Missouri statute).
Given that, in its application to the case before us, “the Double Jeopardy Clause does no more than prevent the sentencing court from prescribing greater punishment than the legislature intended,” Hunter, supra, at 366, the state-court
