Acquittal on Assault Charges in First Trial Did Not Preclude Presentation of Evidence of the Assaults in Second Trial—Collateral Estoppel Doctrine Could Not Be Successfully Invoked Because the Meaning of the Acquittals Was Nearly Impossible to Discern

In a second trial, the defendant moved to preclude the prosecution from introducing evidence of two assaults which were the subjects of acquittals in the first trial.  The trial court allowed evidence of the two assaults.  On appeal the defendant argued that evidence of the assaults of which she was acquitted was precluded by the doctrine of collateral estoppel.  The Fourth Department disagreed and affirmed the trial court’s admission of the evidence, noting that the exact meaning of an acquittal in a criminal trial is often impossible to demonstrate:

“The doctrine of collateral estoppel, or issue preclusion, operates in a criminal prosecution to bar relitigation of issues necessarily resolved in defendant’s favor at an earlier trial” …. Thus, the doctrine applies in a situation such as this, where at a prior trial there was a mixed verdict in which the jury acquitted a defendant of certain charges, but was unable to reach a verdict on the remaining charges ….  “Application of the collateral estoppel doctrine requires that the court determine what the first judgment decided and how that determination bears on the later judgment . . . The rule is easily stated but frequently difficult to implement because the meaning of a general verdict is not always clear and mixed verdicts may, at times, appear inherently ambiguous.  Nevertheless, the court must assume the jury reached a rational result . . . , and a defendant claiming the benefit of estoppel carries the burden of identifying the particular issue on which he [or she] seeks to foreclose evidence and then establishing that the fact finder in the first trial, by its verdict, necessarily resolved that issue in his [or her] favor” …. “Defendant’s burden to show that the jury’s verdict in the prior trial necessarily decided a particular factual issue raised in the second prosecution is a heavy one indeed, and as a practical matter severely circumscribes the availability of collateral estoppel in criminal prosecutions . . . ‘[I]t will normally be impossible to ascertain the exact import of a verdict of acquittal in a criminal trial’ ” …. People v Brandie E…, KA 09-01366, 202, 4th Dept, 4-26-13
