The Second Department noted that a valid waiver of appeal precludes review of the factual sufficiency of a plea allocution, but does not preclude review of a claim of ineffective assistance where the voluntariness of the plea may have been affected:
The defendant’s valid waiver of his right to appeal precludes review of his challenge to the factual sufficiency of his plea allocution … . While the valid waiver of his right to appeal would typically preclude review of the defendant’s claim that he was deprived of his right to effective assistance of counsel, here, the defendant claims that the alleged ineffective assistance may have affected the voluntariness of his plea, and, as such, his claim is reviewable … . Nevertheless, contrary to the defendant’s contention, his attorney provided him with meaningful representation … . Moreover, the Supreme Court providently exercised its discretion in denying the defendant’s motion to withdraw his guilty plea … . People v Milton, 2013 NY Slip Op 07507, 2nd Dept 11-13-13
