Harris v. Washington Applied
The record in Ashe was favorable to the defendant in several ways: the robbery itself was uncontested, the first trial turned on identity alone, and the State later admitted it had used that trial as a rehearsal. A reader could fairly ask whether the rule depends on those features. Harris v. Washington answers that it does not. The Court held that issue preclusion, the rule that an issue already decided between the same parties cannot be litigated again, bars a second prosecution when an ultimate issue such as the identity of the person who committed the act was decided in the defendant's favor at the first trial, even if the first jury lacked all the relevant evidence and the State acted in good faith in bringing the second case.1 The state court had declined to apply Ashe because identity had not been "fully litigated" at the first trial, since the trial judge had excluded evidence on grounds having "no bearing on the quality of the evidence."2 The Supreme Court reversed, holding that the guarantee applies "irrespective of whether the jury considered all relevant evidence, and irrespective of the good faith of the State in bringing successive prosecutions."3
The holding has two parts, and each has its own reason. The first concerns incomplete evidence. Preclusion attaches to what the first verdict decided; how well informed that verdict was does not enter the analysis. Once a jury determines an ultimate issue in the defendant's favor, the same issue cannot be relitigated in a later proceeding.4 If the completeness of the first presentation could reopen the issue, the State could reopen it in almost every case, because it can nearly always point to a witness it did not call or an exhibit the judge did not admit, and the rule would give way in just the cases it exists to cover. The same logic governs acquittals generally, which stay final even when the trial judge improperly excluded prosecution evidence or gave faulty instructions.5 A second trial after even a mistaken acquittal would let the State, with its far greater resources, wear the defendant down until an innocent person might be convicted.6 Harris applies that reasoning to the single issue a verdict resolved.
The new witness changes the quality of the State's proof, and the first verdict is untouched by that change, because the verdict is defined by what the jury decided and not by what it might have heard. The trap is treating a stronger second case as a reason to reopen an issue the first jury already resolved. Preclusion asks only what the verdict established, and in the burglary example it established the answer on identity.
The second part of the holding concerns the State's motives. Good faith in bringing the second case is no answer to a preclusion claim, and the reason follows from what the protection secures. The harm the guarantee prevents is an acquitted person being made to defend again on an issue a jury has already resolved, and that burden is identical whether the prosecutor acted from bad motives or sincerely believed the second case was proper. A motive-based exception would also tie the protection to a fact the State is best placed to describe and the defendant least able to disprove. In Ashe the State had frankly conceded that it treated the first trial as no more than a dry run for the second prosecution, and a reader might suppose that this candor drove the result. Harris shows that it did not, because the rule applies even when the State's conduct looks sympathetic rather than strategic.7
That rule does not mean a defendant may invoke Ashe regardless of how the separate trials came about. In Currier v. Virginia the Court rejected an Ashe claim from a defendant who had asked that one charge be severed and tried last, so the separate trials were of the defendant's own making.8 That boundary belongs with the State's charging and joinder choices, which come later in this chapter, and it leaves the good-faith point intact for a defendant who did nothing to split the trials.
Preclusion also fails where the first verdict did not necessarily decide the issue the State wants to prove again, and the contrast with the burglary example shows which fact does the work.
The only difference between the two examples is the range of grounds on which the first jury could rationally have acquitted. Neither the missing evidence nor the State's sincerity moves the answer in either direction; what moves it is whether the verdict necessarily resolved identity, a question the next section takes up under the heading of reading the prior verdict. One naming caution belongs here as well. Younger v. Harris, 401 U.S. 37 (1971), is a different decision despite the shared name: it concerns whether a federal court may enjoin a pending state prosecution and is not a double jeopardy case.9
