    The People of the State of New York, Respondent, v Chad Santmyer, Appellant.
    [648 NYS2d 69]
   Judgment unanimously affirmed. Memorandum: County Court properly exercised its discretion in excluding evidence of the complainant’s prior sexual encounter with another prosecution witness (see, CPL 60.42 [5]; People v Baldwin, 211 AD2d 638, lv denied 85 NY2d 935). The court properly permitted the prosecutor to question defendant about a previous assault conviction after defendant "opened the door” to such inquiry by testifying that he was not a violent person (see, People v Rios, 166 AD2d 616, 618, lv denied 77 NY2d 842). Defendant bore the burden of seeking an advance ruling on the admissibility of that conviction for purposes of impeachment (see, People v Matthews, 68 NY2d 118, 123) and any delay in the court’s Sandoval ruling is attributable to defendant’s failure to inform the court of the conviction (see, People v Sandoval, 34 NY2d 371, 378). Defendant’s challenge to the integrity of the Grand Jury proceeding (see, CPL 210.35 [5]) was not timely (see, CPL 255.20 [1], [3]). Defendant received meaningful representation (see, People v Satterfield, 66 NY2d 796, 798-799). The sentence imposed is not unduly harsh or severe. Defendant’s remaining contentions are not preserved for our review (see, CPL 470.05 [2]), and we decline to exercise our power to address them as a matter of discretion in the interest of justice (see, CPL 470.15 [6] [a]).
