The Prosecutor’s Acting As an Unsworn Witness (Suggesting He Had Been Present at a Trial In Which the Defense Expert Had Lied) and The Prosecutor’s Repeated Questioning of the Expert and Another Defense Witness About Their Alleged Lying Deprived Defendant of a Fair Trial on the Murder Count

The Second Department reversed defendant’s murder conviction because of the misconduct of the prosecutor in questioning the defense expert and another defense witness.  The prosecutor acted as an unsworn witness by suggesting he was present in a trial where the defense expert lied and the prosecutor improperly and repeatedly questioned the expert and another defense witness about their alleged lying:

The prosecutorial misconduct during the voir dire questioning and cross-examination of the defense’s expert included statements that the expert had repeatedly lied to judges in other cases and during his testimony in the instant case. In addition, the prosecutor presented himself as an unsworn witness at the trial, suggesting that he had been present at the trial of another case at which the defendant’s expert had lied. The prosecutor furthermore repeatedly questioned another defense witness about lying. The cumulative effect of this misconduct … unfairly deprived the defendant of the ability to present his defense of extreme emotional disturbance to the charge of murder in the second degree … . People v Martinez, 2015 NY Slip Op 03568, 2nd Dept 4-29-15
