Whether the Double Jeopardy Clause requires credit for punishment already served under a conviction later set aside when the defendant is reconvicted of the same offense.
Holding
Yes. The Constitution requires full credit for all punishment already exacted, including time served and applicable good-time credit, when sentencing after reconviction for the same offense.
Reasoning
The Double Jeopardy Clause protects not only against a second prosecution after acquittal or conviction, but also against multiple punishments for the same offense. Its protection against multiple punishment applies even when the defendant himself obtained reversal of the first conviction.
Without credit, the State would effectively add a new punishment to punishment already served. A defendant who served three years on a vacated conviction and then received a new ten-year sentence for an offense carrying a ten-year maximum would serve thirteen years for an offense the legislature authorized punishment by no more than ten years.
The Court rejected the idea that time spent imprisoned under an invalid conviction can simply be ignored. Although a later acquittal cannot restore lost years, a reconviction permits—and constitutionally requires—the State to return those years by subtracting them from the new sentence. Rice therefore could not be denied credit for his prior imprisonment.
