Unfortunately, there’s not really an analogous concept in double jeopardy jurisprudence. In our system, jeopardy attaches to a case when the finder of fact begins its role. Literally: jeopardy attaches to a case the instant the jury is sworn in. At a bench trial, jeopardy attaches the moment the judge begins hearing evidence (as opposed to argument). Our notion of double jeopardy does not contemplate any subsequent finder of fact trumping the first.
The trial judge would do that because he believes that, as a matter of law, the trial record did not reflect evidence that, if believed by the jury, could support a “beyond a reasonable doubt” verdict.
Let’s examine some specific scenarios.
Craig is charged with armed robbery. A store clerk testifies that a masked man, wearing blue jeans and a red hoodie, pointed a gun at her and demanded the money from the cash drawer. On cross-examination, the clerk admits she cannot identity Craig as the man, because she never saw his face, although his height and weight are consistent with the robber’s.
A police officer testifies that they responded to an alarm from the store and searched the area. In a nearby alley, they found Craig, wearing blue jeans and a dark T-shirt. He told police a man had rushed by him from the direction of the store, dumped something in a nearby trash container, and fled. The trash container was searched, says the officer, and contained a gun, the stolen money, and a red hoodie. On cross-examination, he admits that there was no physical evidence tying Craig to any of the items. He also blurts out, unasked, that he arrested Craig anyway because he knew Craig was a bad actor: he had previously arrested Craig for child molestation, although he concedes that that prior arrest did not result in a conviction.
Craig testifies at trial consistently with the story he told the officers.
The jury returns a finding of guilty.
The judge sets that verdict aside and orders an acquittal. Even though the jury found guilt, the evidence on which they relied was not sufficient to do so. No physical evidence or testimonial evidence tied Craig to the robbery. The proximity of the gun and money to where Craig was arrested in suspicious, of course, but not enough to prove guilt beyond a reasonable doubt, and the jury should never have heard about the child molestation arrest – it was highly prejudicial and unrelated to the matter on trial.
Now let’s change the facts a bit.
In our second scenario, the officer testifies that he arrested Craig because he had twice previously arrested Craig for armed robbery. In each case, Craig had shed a garment to change his description and claimed that he saw another robber abandon the property and go running away.
The judge sets that verdict aside and orders an acquittal, saying that the jury should never have heard about the prior arrests – it was highly prejudicial.
The prosecution should appeal that ruling, however. Prior bad acts are admissible when offered to prove a common plan, scheme, or motive, or as absence of mistake. The jury was allowed to consider that evidence along with the rest, and to infer guilt. The trial judge’s ruling was flawed as a matter of law. The appellate court can reverse the judge’s ruling of acquittal without offending the principle of double jeopardy, because the original jury verdict was “guilty.”
