People v. Feldman 

Defendant pled guilty to unlawful possession of controlled substance. Court properly refused to allow Defendant to withdraw his guilty plea, as he did not claim a factual mistake, but instead that he was aware of alleged prescription but chose to stipulate, at plea hearing, that he did not have valid prescriptions for any of the hydrocodone drugs found in his possession. Defendant was accurately and meticulously admonished about his rights and the plea consequences. Defendant is estopped, by his waiver of proof (through his judicial admission), from contesting his prior stipulation. (DONOVAN and WEXSTTEN, concurring.)
