OPINION

RACANELLI, P.J.

Pursuant to a plea bargain, defendant pled guilty in the municipal court to maintaining a place for the sale of heroin; an additional charge of sale of heroin was dismissed. Defendant was thereafter sentenced by the superior court to prison for the middle term of two years.

I. Habeas Corpus^fn_

D. APPEAL

(1a) Finally, defendant argues Mr. Jaycox neglected to preserve his appeal by failing to file a timely notice of appeal and to obtain a certificate of probable cause.

Defendant was sentenced on September 21, 1987, and the written judgment and abstract of judgment were signed and filed the next day. (2) (See fn. 2.) The notice of appeal prepared and signed by his attorney was not filed until November 23, 1987, three days beyond the prescribed sixty-day period. (1b) Accordingly, we grant the petition for habeas corpus only insofar as it seeks to perfect a timely notice of appeal. Because defendant justifiably relied on his attorney to initiate the filing of the notice of appeal, we apply the doctrine of constructive filing and deem the notice of appeal timely filed. ( In re Benoit (1973) 10 Cal.3d 72, 86-87 [ 109 Cal.Rptr. 785, 514 P.2d 97]; see also In re Hernandez (1974) 40 Cal.App.3d 893 [ 115 Cal.Rptr. 495].)

Penal Code section 1237.5 normally requires a certificate of probable cause for an appeal after a plea of guilty or nolo contendere. (3) But no probable cause certificate is required if the appeal is "based solely upon on grounds (1) occurring after entry of such plea which do not challenge the validity of the plea or (2) involving a [contested] search or seizure. . . ." (Cal. Rules of Court, rule 31(d).) (Hereafter rule 31(d).) Sentencing questions fall within the former exception. ( People v. Sumstine (1984) 36 Cal.3d 909, 915, fn. 3 [ 206 Cal.Rptr. 707, 687 P.2d 904]; People v. Jerome (1984) 160 Cal.App.3d 1087, 1098 [ 207 Cal.Rptr. 199].) Accordingly, defendant was not required to obtain a certificate of probable cause to raise his alleged claim of sentencing error.

But rule 31(d) further provides that "the appeal shall not be operative unless the notice of appeal states that it is based upon such grounds." (4) (See fn. 3.), (5) In the present case, defendant's notice of appeal does specify a ground, but it is not the sentencing issue now asserted on appeal. The question therefore arises whether this court may properly hear defendant's appeal.

In People v. Ballard (1985) 174 Cal.App.3d 982 [ 220 Cal.Rptr. 323], this court viewed the rule 31(d) requirement that appropriate grounds be stated in the notice of appeal as jurisdictional. We there held that when a notice of appeal fails to include a cognizable ground, the appeal "is not operative [and t]he appropriate disposition for such an inoperative appeal is dismissal." (174 Cal.App.3d at p. 985.)

In Ballard, the defendant belatedly attempted to raise a search and seizure issue and other undefined issues on appeal subsequent to his guilty plea. Following our review and discussion of relevant authorities, we determined that defendant was precluded from raising the other issues because he had not obtained a certificate of probable cause. (174 Cal.App.3d at pp. 986-989.) We further concluded that as to the search and seizure issue (for which no certificate of probable cause is required), defendant was likewise precluded by reason of his failure to specify an appropriate ground in his notice of appeal: "That defendant's search and seizure contention would have been cognizable on this appeal if he had complied with the second paragraph of rule 31(d) provides no good reason for our ignoring the fact that he has not complied. Nor does any good reason occur to us for giving `shall not be operative' a different meaning in the second paragraph of rule 31(d) from that which it has in the first paragraph." ( People v. Ballard, supra, 174 Cal.App.3d at p. 989.)

Here, as noted, defendant seeks to raise a postplea claim of sentencing error without having specified such ground in his notice of appeal as required by rule 31(d). Our analysis of the question presented requires that we reexamine the broad language of our holding in Ballard concerning the legal effect of such noncompliance. We will conclude that the omission from the notice of appeal of an appropriate ground for an appeal following a guilty plea is not a jurisdictional defect. As we will explain, we construe the language in the second paragraph of rule 31(d) to affect only the process for preparation of the record by the superior court clerk and not the jurisdictional competency of this court to consider a cognizable appeal.

As earlier noted, Penal Code section 1237.5 establishes the jurisdictional limits of this court over appeals after a guilty plea: "No appeal shall be taken" without a certificate of probable cause. Rule 31(d) implements that statutory requirement. ( People v. Laudermilk (1967) 67 Cal.2d 272, 281, fn. 8 [ 61 Cal.Rptr. 644, 431 P.2d 228], cert. den. 393 U.S. 861 [21 L.Ed.2d 128, 89 S.Ct. 139].)

When originally promulgated in 1965, rule 31(d) declared that following a guilty plea a notice of appeal "shall not be operative" unless a certificate of probable cause is filed within specified time limits. Further, the final paragraph of the rule provided then, as now: "The time for preparing, certifying and filing the record on appeal or for filing an agreed statement shall commence to run when the appeal becomes operative."

This language signifies that the operative status of the appeal directly relates to the preparation of the record. The rule was apparently designed to instruct superior court clerks not to prepare the record on improper appeals that would surely be dismissed by the Court of Appeal. (See Davis v. Superior Court (1969) 272 Cal.App.2d 707, 709-710 [ 77 Cal.Rptr. 779].)

However, as a result of the holding in People v. Ward (1967) 66 Cal.2d 571 [ 58 Cal.Rptr. 313, 426 P.2d 881], which carved out an exception to section 1237.5 (postplea errors appealable without a certificate of probable cause), a dilemma was created for superior court clerks since the absence of a certificate of probable cause no longer signalled that the record need not be prepared. (See In re Harrell (1970) 2 Cal.3d 675, 706 [ 87 Cal.Rptr. 504, 470 P.2d 640], cert. den. 401 U.S. 914 [27 L.Ed.2d 814, 91 S.Ct. 890]; Davis v. Superior Court, supra, 272 Cal.App.2d at p. 710.)

This predicament led then Presiding Justice Kaus in Davis v. Superior Court, supra, to suggest a temporary solution that a defendant seeking to raise postplea errors should file a statement so stating. "If such a statement is filed, the appeal should be processed. If no such statement is filed, no record needs to be prepared." (272 Cal.App.2d at p. 710.) The obvious purpose of Justice Kaus's suggested expedient was to alert the superior court clerks for purposes of record preparation.

In response to this suggested procedure, the Judicial Council in 1970 added the second paragraph to rule 31(d) to provide, as now, that if a defendant appealed upon postplea grounds which do not challenge the plea itself, the requirements of Penal Code section 1237.5 are inapplicable, "but the appeal shall not be operative unless the notice of appeal states that it is based upon such grounds." Like the language in the first paragraph of rule 31(d) concerning appeals requiring a certificate of probable cause, this language is similarly directed to the superior court clerks. (See People v. Ribero, supra, 4 Cal.3d at p. 64, fn. 5.)

In short, rule 31(d) does no more than establish a screening mechanism for the aid and benefit of superior court clerks regarding their obligation to prepare an appellate record. The clerks are instructed that no record need be prepared unless the defendant who appeals following a guilty plea has complied with the requirements of Penal Code section 1237.5 (1st par.) or has filed a notice of appeal clearly reflecting that the statutory statement and certificate are unnecessary (2d par.). (See People v. Ballard, supra, 174 Cal.App.3d at p. 988; People v. Nigro (1974) 39 Cal.App.3d 506, 509-510 [ 114 Cal.Rptr. 213].)

We conclude that the specification of appropriate grounds in the notice of appeal is not a jurisdictional requirement. Thus, if the clerk were to process the appeal even in the absence of such specification, the defective notice of appeal would not bar appellate review. The defendant's failure to specify the requisite grounds — which in theory would indefinitely suspend preparation of the record — is not a jurisdictional defect and does not otherwise preclude consideration of the merits of the appeal. ( People v. Brown (1985) 166 Cal.App.3d 1166, 1168, fn. 1 [ 212 Cal.Rptr. 907]; People v. Engel (1980) 105 Cal.App.3d 489, 494-495 [ 164 Cal.Rptr. 454].)
