dissents in part as to defendant Pollock in a memorandum, as follows: I am in agreement with the court’s response to the issues presented *609by defendant Garcia’s motion for a new trial. However, I believe the conviction of the defendant Pollock should be reversed because the trial court, in denying his Sandoval motion, failed to apply the balancing test there mandated. The defendants were charged with the criminal sale of a controlled substance in the first degree arising out of an alleged sale of some four pounds of cocaine to an undercover police officer. Prior to trial, Pollock applied, pursuant to People v Sandoval (34 NY2d 371), to preclude the prosecution from cross-examining him should he take the witness stand in his own defense as to a pending drug charge quite comparable to that for which he was on trial. The motion was denied. The critical question on such a motion is whether (p 378) "the prejudicial effect of the admission of evidence thereof for impeachment purposes would so far outweigh the probative worth of such evidence on the issue of credibility as to warrant its exclusion.” I should have thought it obvious that the prejudicial impact of inquiry with regard to a pending narcotic charge closely analogous to the charge, on trial, would inevitably far exceed the legitimate value for impeachment purposes of such inquiry. However, the postSandoval decisions have shown a clear disposition to grant considerable discretion to Trial Judges in this area. (See, e.g., People v Duffy, 36 NY2d 258, 262-263.) What is more disturbing, however, is that in his explanatory comments, the Trial Judge indicated an approach to the issue that cannot be reconciled with the balancing test articulated in Sandoval. Thus, he stated: "The case has to be a rather extreme one, in my opinion or the circumstances have to be extreme, when such a motion is granted. As long as the crime involved does entail moral turpitude it seems to me that the jury has a right to know about it in evaluating the credibility of the witness.” Although reaffirming the broad discretionary power of the trial court with regard to such motions, the Court of Appeals has made it unmistakably clear that the Trial Judge must apply the balancing test set forth in Sandoval in the exercise of that discretion. (See People v Mayrant, 43 NY2d 236, 239; People v Davis, 44 NY2d 269.) In People v Mayrant (supra, p 240) the court said: "The difficulty with the Trial Judge’s determination here, however, is that, from the record before us, its language being accorded its ordinary meaning, we are compelled to conclude that, in denying defendant’s application, the court failed to consider both of the available alternatives * * * To the contrary, the Judge’s words suggest that he took into account only 'the defendant’s prior propensities for committing violent acts.’ ” The identical error occurred here. As in Mayrant, the surrounding circumstances are such that the error, which could have effectively precluded the defendant from testifying must be deemed prejudicial. Accordingly, Pollock’s conviction should be reversed and a new trial directed.
