In People v Towsley, 2008 NY Slip Op 06054 [4th Dept 7/3/08] [here], the Fourth Department held that it was an abuse of discretion for the trial court to issue a Sandoval ruling permitting the defendant to be cross examined regarding a prior Youthful Offender adjudication. This error was deemed harmless; but this seems like a ruling to remember when you have a client who previously received YO status.
