*614 Opinion
Petitioners are scheduled to be sentenced for a'violation of Vehicle Code section 23102, subdivision (a) (driving under the influence of intoxicating liquor). Each petitioner has admitted that he suffered one or more prior convictions of the same offense pursuant to guilty pleas entered after October 25, 1973, the date of the decision in
Mills
v.
Municipal Court
(1973)
Thereafter, each petitioner filed a petition for an alternative writ of prohibition and/or mandate in the superior court to compel the respondent court to strike his prior convictions. The superior court denied the petitions. Each petitioner thereafter filed a petition for a writ of supersedeas in this court. We chose to consider the petitions as a request for a writ of mandate and stayed all proceedings in the respondent court pending further order.
The fundamental issue is whether petitioners’ prior convictions of drunk driving are constitutionally invalid because the records of the entry of the guilty pleas do not show on their face that the petitioners expressly and explicitly waived their constitutional rights. Included within this question is whether an inadequate record of a waiver of constitutional rights creates a conclusive presumption of invalidity of the guilty plea so that the People are barred from offering any evidence outside the record to prove a valid waiver or whether the presumption is rebuttable so that the People may present extrinsic evidence to prove the waiver.
In
Boykin
v.
Alabama, supra,
the Supreme Court reversed a felony conviction which followed a plea of guilty because the record did not disclose that the accused voluntarily and understandingly waived his constitutional rights against self-incrimination, to trial by jury, and to confront one’s accusers. In
In re Tahl, supra,
In
Mills
v.
Municipal Court, supra,
Finally, in
Stewart
v.
Justice Court
(1977)
The present cases involve docket sheet entries which, like those in Stewart, do not recite that the petitioners expressly and explicitly waived their constitutional rights. 1
The People concede that the docket entries in the present cases do not comply with the requirements of Stewart, supra. Nonetheless, the Attorney General argues that the defective record merely raises a *616 rebuttable presumption as to the unconstitutionality of the plea; that the People should be allowed to present extrinsic evidence showing that petitioners were in fact advised of and expressly waived each of their Boykin-Tahl rights.
Assuming that an inadequate record raises a “presumption” that the defendant did not knowingly and voluntarily waive his constitutional rights, we hold that the presumption should be deemed conclusive for several reasons: First, in
Boykin
it is stated, “When the judge discharges that function [proper taking of plea on record] he leaves a record adequate for any review that may be later sought [citation] and forestalls the spin-off of collateral proceedings that seek to probe
murky
memories.” (Italics added,
Boykin
v.
Alabama, supra,
Second, one important purpose of the
Boykin-Tahl-Mills
rule is to simplify the process of ruling on the adequacy of guilty pleas by encouraging the development of complete records. Permitting extrinsic evidence to take the place of on-the-record evidence would be to undercut
Mills
and defeat the goal of simplification. It would strain the already overworked superior and municipal courts. (See
Stewart
v.
Justice Court, supra,
Third, the proposition that the People would be able to show a valid waiver in the face of a defective record is illusory at best. Because of the volume of pleas entered in our municipal and justice courts, it is doubtful that judges or court personnel would have any specific recollection of what an accused was asked and said in a specific case. Circumstantial evidence as to habit and custom of a judge in accepting guilty pleas would not suffice to rebut the presumption of invalidity. Such inferential
*617
reasoning cannot be used to establish a waiver.
(Stewart
v.
Justice Court, supra,
The People argue that we should declare Stewart v. Justice Court, supra, to be only prospective in its application so as to save the prior convictions here involved. The problem is that Stewart did not establish new law but held simply that the docket sheet used by the Avenal Justice Court after the date of Mills did not affirmatively show on its face the express and explicit waiver required by Mills. Stewart did not extend, add to, modify, or reject in any part the law established in Mills. Thus, we have no alternative but to apply Stewart retroactively to the Mills date—October 25, 1973.
It is ordered that writs of mandate issue in each of the above entitled cases directing that respondent municipal court grant petitioners’ motions to strike the prior convictions.
Brown (G. A.), P. J., and Hopper, J., concurred.
The petition of the real party in interest for a hearing by the Supreme Court was denied January 17, 1979.
Notes
The docket sheets recite: “Defendant advised of, understood, and knowingly and voluntarily waived all the following rights: his privilege against self-incrimination, the right to jury trial, and the right to confrontation and cross-examination of the witnesses against him. After questioning the defendant the Court determined that he understood the nature of the charge, the elements of the offense, the pleas available thereto, the possible defenses thereto, the possible range of penalties and other consequences of his plea (including the effect of the admission of any prior convictions and the required finding of guilt upon a plea of nolo contendere).”
The word “expressly” was subsequently added to the docket sheet by a court employee because of a misunderstanding. The Attorney General concedes it should not be given legal effect.
