Whether the Double Jeopardy Clause incorporates collateral estoppel and applies that protection against the States.
Holding
Yes. Collateral estoppel is an essential component of the Fifth Amendment guarantee against double jeopardy, and it binds the States through the Fourteenth Amendment.
Reasoning
Collateral estoppel means that when a valid final judgment has determined an issue of ultimate fact, the same parties may not litigate that issue again in a later case. Although the doctrine developed in civil litigation, it had long been part of federal criminal law. The Court rejected the idea that criminal defendants should receive less protection against relitigation than civil litigants receive over property or debt.
Benton v. Maryland changed the constitutional setting from that in Hoag v. New Jersey. Hoag had considered only whether a successive state prosecution was fundamentally unfair under general due process principles. After Benton, however, the question was whether the prosecution violated the specific federal guarantee against double jeopardy, making the applicability of collateral estoppel a constitutional question for the Court itself to decide.
The Double Jeopardy Clause protects an acquitted defendant from being forced to "run the gantlet" a second time. That protection would be incomplete if the State could evade an acquittal by bringing a new charge that required it to relitigate the very factual issue the first jury had resolved for the defendant.
