In People v Anderson ( 2011 NY Slip Op 09364 [4th Dept 12/23/11]), after holding the that there was a valid waiver of appeal, the Appellate Division, Fourth Department held that

We agree with defendant, however, that the waiver does not encompass his further contention concerning the denial of his request for youthful offender status. No mention of youthful offender status was made before defendant waived his right to appeal during the plea colloquy. Under those circumstances, we conclude that defendant did not knowingly waive his right to appeal with respect to Supreme Court's denial of the request by defendant for youthful offender status at sentencing (see generally People v McCarthy, 83 AD3d 1533, lv denied 17 NY3d 819; People v Fehr, 303 AD2d 1039, lv denied 100 NY2d 538; People v Hendricks, 270 AD2d 944).

The Court then rejected the defendant's contention that the court abused its discretion in denying his request for youthful offender status and declined to exercise our interest of justice jurisdiction to adjudicate him a youthful offender.
