What rights does an appellant have when pleading guilty to a charge of sexual assault?

Before he entered his plea, appellant was fully advised of his Boykin/Tahl rights, his right to a preliminary hearing, and the penal, financial, and immigration consequences of his plea. (Boykin v. Alabama (1969) 395 U.S. 238; In re Tahl (1969) 1 Cal.3d 122.) Before he was sentenced, appellant claimed he had not understood he was entitled to a preliminary hearing on the charges, but he declined an opportunity to withdraw his plea that was given to him by the court at the sentencing hearing after consulting with counsel. He confirmed that he understood his right to a preliminary hearing, his right to a jury trial, his right to confront and cross-examine witnesses, his right to remain silent, his right to present evidence and the right to be represented by counsel. Appellant was sentenced in accordance with his plea agreement.
