What rights waive by a guilty plea?

The majority's elaborate discussion of the precise extent to which three rights waived by a guilty plea the rights to jury trial, to confrontation and cross-examination of witnesses, and to be free of compelled self-incrimination are available to a probationer is also beside the point. A probationer faced with revocation unquestionably has the rights spelled out in Gagnon v. Scarpelli. They may be different from the rights available to the accused when he is called upon to plead to the original charge, but they are no less important. In both situations the rights waived afford the defendant his primary protection against an unfair deprivation of liberty. The majority seizes upon the fact that before appellant pleaded guilty she was presumably advised of the rights she waived by that plea. But it can hardly be argued from this that appellant was aware of the additional and different rights she waived when she admitted the violations of the conditions of her probation.
