Collateral Estoppel and Double Jeopardy

Collateral Estoppel and Double Jeopardy

The text of the Double Jeopardy Clause speaks only of a person being put in jeopardy twice "for the same offence," and it says nothing about issues, findings, or estoppel.¹ The Supreme Court nonetheless found an issue-preclusion rule inside it. In Ashe v. Swenson the Court held that the doctrine of collateral estoppel is embodied in the Double Jeopardy Clause and bars a later prosecution where an issue of ultimate fact has once been determined by a valid and final judgment.² The Court described the doctrine as meaning "simply that when an issue of ultimate fact has once been determined by a valid and final judgment, that issue cannot again be litigated between the same parties in any future lawsuit."³ That sentence is the rule this chapter develops, and each phrase in it does separate work.

The rule protects the defendant in a way the same-offense inquiry cannot, and the facts of Ashe show why. The second prosecution there charged the robbery of a different poker player. Because the victim was different, the two charges were different offenses, so neither a second prosecution nor added punishment would have been barred by the same-offense test.⁴ That test compares one charge against another and asks whether the crimes overlap. It cannot detect that a legally distinct second charge would force the State to prove again a fact the first jury had decided against it. Preclusion supplies the missing comparison by setting what the first verdict decided against what the second prosecution must prove.⁵ A student who stops at different victims, different offenses has therefore finished only half of the analysis.

Three terms in the rule carry the analysis. A valid and final judgment is one that comes out of a completed proceeding and ends the matter, as an acquittal entered on a jury's verdict does. An issue of ultimate fact is a fact the prosecution must establish as part of its case in the second prosecution, such as whether the defendant was one of the robbers.⁶ The same-parties requirement is met in a criminal case because the State and the accused face each other in both trials, and the State is the party the doctrine binds, since it is the one that lost on the issue. Later sections develop each term: how a court works out what an ordinary general verdict decided, why only facts essential to the first judgment qualify, and why the protection runs to the defendant alone.

The Court treated the rule as a constitutional requirement and not as a convenience borrowed from civil practice. It asked whether the established federal rule was embodied in the Fifth Amendment guarantee against double jeopardy and answered, without hesitation, that it was.⁷ Because the guarantee applies to the States through the Fourteenth Amendment, as Benton v. Maryland held, the rule binds state prosecutors too, and Ashe itself came from a Missouri prosecution.⁸ The reasons for the rule come from two sources. Civil collateral estoppel exists to spare a litigant the burden of relitigating an identical issue and to save courts from needless repeat litigation.⁹ The Double Jeopardy Clause adds a protection for the individual: the State, with all its resources, should not be allowed to make repeated attempts to convict, and a jury's judgment should stay final once it is entered.¹⁰ That is why the State's concession in Ashe that it had treated the first trial as a dry run for the second drew the Court's response that this is precisely what the guarantee forbids, since it protects an acquitted person from having to "run the gantlet" a second time.¹¹

Two situations that differ in one fact show where the rule applies and where it does not. In Ashe the first jury acquitted the defendant of robbing one poker player after a trial in which the only rationally contestable question was whether he was one of the robbers, so the State could not try him for robbing a second player in the same holdup.¹²

Both second charges name a different victim, so the victim cannot be what moves the answer. The difference is whether conviction on the second charge would require the State to prove again a fact the first jury resolved in the defendant's favor. In Ashe it would, and in the Monday and Friday robberies it would not.

The doctrine is real but narrow in practice. Most criminal juries return a general verdict of guilty or not guilty without giving reasons, and most cases require the jury to decide several ultimate issues, so a bare acquittal often does not reveal which issue the jury resolved for the defendant.¹³ The sections that follow show how courts work around that problem and where the doctrine stops.
