In In re Tahl (1969) 1 Cal.3d 122, the California Supreme Court set forth the requirements for a constitutionally valid guilty plea: "The record must contain on its face direct evidence that the accused was aware, or made aware, of his right to confrontation, to a jury trial, and against self-incrimination, as well as the nature of the charge and the consequences of his plea. Each must be enumerated and responses elicited from the person of the defendant." (Tahl, supra, 1 Cal.3d at p. 132, )
