The Court of Appeals, in a full-fledged opinion by Judge Pigott, determined the doctrine of collateral estoppel did not prohibit testimony in defendant's second trial that the defendant threatened to cut a victim's throat with a razor blade, despite the fact defendant was acquitted of charges involving the use of a dangerous instrument in the first trial. The court concluded that the witness-victims could not give truthful testimony about the defendant's actions without reference to the razor blade. Therefore, the collateral estoppel doctrine, under the facts of this case, was properly not applied. The court went on to find that defense counsel's request to withdraw or her motion for a mistrial should have been granted. Defense counsel's statements at arraignment were used to impeach the defendant's version of events. After defense counsel reviewed her notes, she informed the court that her statements at arraignment were incorrect and that defendant's testimony at trial matched what he had told her before arraignment. Under these circumstances, the witness-advocate rule required that defense counsel withdraw or that a mistrial be declared. Defendant's conviction was therefore reversed:

… [T]he rigid application of collateral estoppel sometimes gives way to society's interest in ensuring the correctness of criminal prosecutions … . Thus, … if it becomes apparent … that collateral estoppel “cannot practicably be followed if a necessary witness is to give truthful testimony, then [the doctrine] should not be applied” …. . * * *

[Re: the use of defense counsel's erroneous statement to impeach defendant:] The situation went from bad to worse when it became clear that the only way for defense counsel to rehabilitate her client's credibility was to impugn her own, moments before she would argue for her client's innocence in summation. Any way you look at it, defense counsel had no choice but to withdraw. In these unusual circumstances, we hold that the trial court should have granted counsel's request to withdraw or declared a mistrial. People v Ortiz, 2015 NY Slip Op 09233, CtApp 12-16-15
