The Third Department reversed County Court and determined leading questions and elicitation of hearsay in the grand jury proceedings did not constitute prosecutorial misconduct:

“Dismissal of an indictment pursuant to CPL 210.35 (5) is a drastic, exceptional remedy and should thus be limited to those instances where prosecutorial wrongdoing, fraudulent conduct or errors potentially prejudice the ultimate decision reached by the [g]rand [j]ury” … .  Contrary to County Court’s finding, the record as a whole does not reveal a “pervasive mishandling” of the manner in which this case was presented to the grand jury.  To the extent that the prosecutor asked leading questions or elicited hearsay testimony from the various witnesses, we note that “not every improper comment, elicitation of inadmissible testimony, impermissible question or mere mistake renders an indictment defective.  [Rather], the submission of some inadmissible evidence [typically] will be deemed fatal only when the remaining evidence is insufficient to sustain the indictment” … .  Inasmuch as we are satisfied – based upon our review of the grand jury minutes – that there otherwise is legally sufficient (and admissible) evidence to sustain count 1 of the indictment, the isolated instances of hearsay testimony, which were accompanied by appropriate limiting instructions, do not warrant dismissal thereof … .  We similarly are persuaded that the prosecutor’s limited use of leading questions did not impair the integrity of the grand jury proceeding… . People v Miller, 105721, 3rd Dept 10-17-13
