Kline, P.J.In 1997, Jon Eric Clark was convicted of indecent exposure and sentenced to a prison term of 26 years to life under the "three strikes" law. In 2014, after adoption of the Three Strikes Reform Act (Reform Act), he petitioned for resentencing. This appeal is from the denial of that petition. Appellant contends the trial court erred in failing to conduct a hearing and rule on his motion to strike one of his prior convictions on the ground that it was constitutionally invalid and in ruling it lacked authority to dismiss the prior conviction in the interests of justice. He additionally contends the court's implied finding that he was ineligible for resentencing due to a prior conviction under Penal Code section 288 violated his constitutional right to equal protection because a similarly situated defendant with a prior conviction for the more serious offense of violating Penal Code section 288.7 would be eligible for resentencing. We affirm.

STATEMENT OF THE CASE AND FACTS

In August 1996, a customer eating at a McDonald's observed appellant sitting by himself at another table, exposing his erect penis by pulling up the leg of his shorts. Appellant was charged with indecent exposure (Pen. Code, § 314.1), by amended information filed on May 6, 1997; the offense was charged as a felony due to prior convictions of the same offense in 1971, 1973 and 1974, and prior convictions of lewd and lascivious conduct (§ 288, subd. (a) ) in 1974 and 1985. The two section 288 convictions were alleged as strikes under section 1170.12, subdivision (c)(2), and the 1985 conviction was additionally alleged as a prior prison term under section 667.5, subdivision (b). Appellant admitted having been convicted of the priors alleged in the section 314.1 charge for purposes of the present offense being charged as a felony. Appellant was found guilty of the present offense after a jury trial, and the court found the alleged strike and prison term prior convictions true. The trial court denied appellant's motion to reduce his conviction to a misdemeanor and strike his prior strikes, and sentenced him to a prison term of 26 years to life.

Appellant unsuccessfully appealed to this court (A081042) on grounds unrelated to the issues now before us. He also filed a petition for writ of habeas corpus (A085538) alleging that his 1974 prior conviction was constitutionally invalid in that the record of his guilty plea did not show he was aware he was waiving his rights to jury trial, to confront and cross examine witnesses and against self-incrimination (Boykin v. Alabama (1969) 395 U.S. 238, 242–244, 89 S.Ct. 1709, 23 L.Ed.2d 274 ; In re Tahl (1969) 1 Cal.3d 122, 81 Cal.Rptr. 577, 460 P.2d 449 (Tahl )), or that he was aware he would have to register as a sex offender for life as a consequence of his plea. We denied the petition and the California Supreme Court denied a habeas petition filed in that court.

In 2012, the California electorate adopted Proposition 36, the Reform Act as part of which section 1170.126 was added to the Penal Code. Section 1170.126 provided for the resentencing of individuals then serving three strike indeterminate prison terms for offenses not defined as serious and/or violent felonies. (Prop. 36, § 6, approved Nov. 6, 2012, eff. Nov. 7, 2012.) In the specified circumstances, such individuals would instead receive two-strike sentences. (§§ 1170.126, subd. (b), (e) ; 1170.12, subd. (c)(2)(C).) As relevant here, persons with prior convictions for certain felonies, including section 288, are not eligible for resentencing under section 1170.126. (§§ 1170.126, subd. (e)(3) ; 1170.12, subd. (c)(2)(C)(iv)(III).)

On July 8, 2014, appellant filed a petition for resentencing under section 1170.126, alleging that his 1974 conviction was constitutionally invalid under Boykin and that his prior section 288 convictions did not render him ineligible for resentencing because it would violate his constitutional right to equal protection to find him ineligible based on those convictions when a similarly situated person convicted of violatingsection 288.7, a more serious offense, would not be found ineligible.

Opposing the petition, the district attorney argued that appellant was statutorily ineligible for resentencing due to his prior section 288 convictions; the trial court had no authority to consider the validity of the priors in a section 1170.126 proceeding; and there was no equal protection violation. Alternatively, the district attorney argued the trial court should exercise its discretion under section 1170.126, subdivision (g), to deny the petition for resentencing. In support of its argument that section 1170.126 provided no authority for the court to disregard the finality of prior judicial decisions in this case, the district attorney provided the 1999 opinion of this court affirming the 1997 judgment and denying the writ petition by which appellant previously challenged the 1974 conviction; the Attorney General's 1999 informal opposition to the writ petition; and the 1987 opinion of the Fifth District Court of Appeal affirming appellant's 1985 section 288 conviction. The 1985 opinion, among other things, rejected appellant's argument that the 1974 section 288 conviction should have been stricken under Boykin /Tahl.

Responding to the prosecutor's arguments, appellant submitted documentation of his discipline-free prison record and participation and positive performance in rehabilitative programs, and of various health conditions including diabetes and heart problems. Appellant also raised a new issue, asking the trial court to dismiss the case in the interests of justice under section 1385, as appellant had already served 17 years in prison for the 1997 offense, for which the maximum sentence was three years, and Proposition 36 reflected the voters' belief that individuals convicted of more serious crimes than appellant's should be released after serving only a two-strike sentence (in this case, six years).

At the hearing on October 16, 2014, defense counsel argued there was evidence that appellant was not advised of his rights when he entered the 1974 plea: Although there was neither a plea form nor a transcript of the proceedings, the Certificate of the Magistrate indicated that "advice of rights was waived so there wasn't even a reading of the advice of rights." The declaration of the then-clerk for the superior court judge stated that "there was not a giving of the advice of rights and a waiver of such a right to those reaffirming their plea." The declaration of current appellate counsel stated, based on his experience as a public defender in Santa Clara County at the time, that prior to 1977, when the determinate sentencing law took effect, there was not a practice of carefully ensuring defendants were advised of and waived their rights, and plea forms were not used. Trial counsel additionally argued at the hearing that although the 1974 prior was challenged at the time of appellant's 1985 conviction, counsel at that time was "ill prepared" and did not have the Magistrate's Certificate that had since been found.

Recognizing that it had declined to strike appellant's priors at the time of trial and there was no law on the question whether that issue could be revisited on a petition for resentencing, the court denied the petition, explaining that "under the statute as it stands, [appellant] is ineligible for resentencing. I don't find the Equal Protection argument to be compelling. [¶] I appreciate that the court has inherent powers with regard to [section] 1385, but I don't think it was the intent of ... both the drafters of the law and the public in enacting the law that the court would simply skip ahead to the suitability portion and ignore the eligibility portion of the law."

Appellant filed a timely notice of appeal on October 21, 2014.

DISCUSSION

Prior to the adoption of Proposition 36, a defendant who had previously been convicted of two or more serious or violent felonies was subject to an indeterminate sentence of 25 years to life upon conviction of any new felony. (People v. Chubbuck (2014) 231 Cal.App.4th 737, 740, 180 Cal.Rptr.3d 127 (Chubbuck ); People v. White (2014) 223 Cal.App.4th 512, 517, 167 Cal.Rptr.3d 328 (White ); People v. Superior Court (Kaulick) (2013) 215 Cal.App.4th 1279, 1285, 155 Cal.Rptr.3d 856 (Kaulick ).) "The Reform Act prospectively changed the Three Strikes law by reserving indeterminate life sentences for cases where the new offense is also a serious or violent felony , unless the prosecution pleads and proves an enumerated disqualifying factor. In all other cases, a recidivist defendant will be sentenced as a second strike offender, rather than a third strike offender." (Chubbuck, at pp. 740–741, 180 Cal.Rptr.3d 127 ; Kaulick, at p. 1286, 155 Cal.Rptr.3d 856 ; People v. Yearwood (2013) 213 Cal.App.4th 161, 167–168, 151 Cal.Rptr.3d 901 (Yearwood ).)

"The Reform Act also created a ‘ "post-conviction release proceeding" ’ whereby a Three Strikes prisoner who is serving an ‘indeterminate life sentence’ for a crime that was not a serious or violent felony—and who is not otherwise disqualified—may have his or her sentence recalled and be resentenced as a second strike offender, unless the court ‘determines that resentencing ... would pose an unreasonable risk of danger to public safety.’ (§ 1170.126, subds. (a), (f), (m); see Yearwood, supra, 213 Cal.App.4th at p. 168 .)" (Chubbuck, supra, 231 Cal.App.4th at p. 741, 180 Cal.Rptr.3d 127 ; White, supra, 223 Cal.App.4th at p. 517, 167 Cal.Rptr.3d 328.)

Under section 1170.126, subdivision (e)(3), an inmate is not eligible for resentencing if he or she has a prior conviction for any offense appearing in section 667, subdivision (e)(2)(C)(iv), or section 1170.12, subdivision (c)(2)(C)(iv). As relevant here, the referenced offenses include a "lewd or lascivious act involving a child under 14 years of age, in violation of Section 288." (§ 1170.12, subdivision (c)(2)(C)(iv)(III).)

I.

Relying upon the principle that a criminal defendant's punishment may not be enhanced on the basis of a prior felony conviction obtained in violation of the defendant's constitutional rights (People v. Allen (1999) 21 Cal.4th 424, 429, 87 Cal.Rptr.2d 682, 981 P.2d 525 (Allen ); Garcia v. Superior Court (1997) 14 Cal.4th 953, 959, 59 Cal.Rptr.2d 858, 928 P.2d 572 (Garcia )), appellant argues that in determining whether an inmate has a prior conviction that renders him or her ineligible for resentencing, the trial court must determine not only whether such a prior conviction exists but also whether it is constitutionally valid. His 1974 conviction, he maintains, was not valid because his plea was taken in violation of his rights under Boykin / Tahl .

As indicated above, appellant unsuccessfully sought to have his prior convictions stricken at his 1997 trial and, subsequently, unsuccessfully argued in a petition for writ of habeas corpus that trial counsel was ineffective for failing to challenge the 1974 prior as constitutionally invalid under Boykin / Tahl . Appellant now urges that he was denied a fair hearing on the validity of the 1974 prior, first by his 1997 attorney's failure to challenge the prior and then by this court denying his habeas petition without issuing an order to show cause, which appellant views as having deprived him of due process.

At the time of appellant's writ petition, the question whether a defendant could move to strike a prior conviction on Boykin / Tahl grounds in a current proceeding was pending before the California Supreme Court, and appellant believes that this court denied the petition because it expected the procedure to be disallowed. Although the motion to strike procedure had been approved in this context by Sumstine , supra , 36 Cal.3d 909, 206 Cal.Rptr. 707, 687 P.2d 904, the viability of that decision had come into question after the United States Supreme Court held that the federal Constitution does not authorize a motion to strike a prior state felony conviction except on grounds of denial of the right to appointed counsel (Gideon v. Wain w right (1963) 372 U.S. 335, 83 S.Ct. 792, 9 L.Ed.2d 799 ) in the former proceeding (Custis v. United States (1994) 511 U.S. 485, 114 S.Ct. 1732, 128 L.Ed.2d 517 (Custis )), and the California Supreme Court held that a defendant in a current prosecution for a noncapital offense may not use a motion to strike to challenge a prior conviction on the ground of ineffective assistance of counsel. (Garcia, supra, 14 Cal.4th 953, 59 Cal.Rptr.2d 858, 928 P.2d 572.) A few months after this court denied appellant's habeas petition, however, Allen held that Sumstine survived Custis , reaffirming that a Boykin / Tahl challenge to a prior conviction could be raised by a motion to strike the prior conviction. (Allen, supra, 21 Cal.4th at p. 427, 87 Cal.Rptr.2d 682, 981 P.2d 525.)

Appellant suggests that various unpublished opinions issued in the time between the Garcia and Allen decisions provide circumstantial evidence that this court viewed Sumstine as no longer valid and therefore disallowed motions to strike that would require evidentiary hearings to determine the validity of the prior. The decisions to which he points relied on considerations of judicial efficiency to hold that where determination of the validity of prior convictions would require an evidentiary hearing, the priors could not be challenged in a current proceeding but only by petition for writ of habeas corpus. Judicial efficiency was one of the bases for the decisions in Custis , which limited motions to strike to claims of denial of the right to appointed counsel in the prior proceeding, and Garcia , which prohibited use of motions to strike to challenge priors on grounds of ineffective assistance of counsel: Unlike challenges to a prior conviction based on complete denial of the right to counsel, which can easily be ascertained from the record of the prior proceeding, a challenge on grounds of ineffective assistance of counsel would often require a time-consuming and disruptive factual investigation. (Custis, supra, 511 U.S. at p. 496, 114 S.Ct. 1732 ; Allen, supra, 21 Cal.4th at pp. 433–434, 87 Cal.Rptr.2d 682, 981 P.2d 525 ; Garcia, supra, 14 Cal.4th at pp. 964–965, 59 Cal.Rptr.2d 858, 928 P.2d 572.) Appellant's speculation about the reason for this court's denial of his 1999 habeas petition does not provide a basis for finding the violation of due process he asserts. It is speculation, nothing more. In opposing the petition, respondent offered various grounds for denial, arguing not only that the pending decision in Allen might demonstrate the Boykin /Tahl challenge could not be raised on a motion to strike, but also that appellant's claim was barred by his failure to justify a 25-year delay in seeking habeas corpus relief (especially since appellant had challenged the validity of the 1974 prior by motion to strike in his 1985 case) and by the previous rejection of the same challenge in appellant's appeal from his 1985 conviction. Respondent also disputed the merits of the claimed invalidity. We decline appellant's invitation to speculate as to the reasoning behind the denial of the petition. Moreover, appellant's argument begs the fundamental question, which is whether the trial court had authority to consider a Boykin / Tahl challenge to the 1974 prior in the context of a petition for resentencing under section 1170.126. In general, " ‘a trial court lacks jurisdiction to resentence a criminal defendant after execution of sentence has begun.’ " (People v. Turrin (2009) 176 Cal.App.4th 1200, 1204, 98 Cal.Rptr.3d 471, quoting People v. Howard (1997) 16 Cal.4th 1081, 1089, 68 Cal.Rptr.2d 870, 946 P.2d 828.) The premise of appellant's argument, as we have said, is that a constitutionally invalid prior conviction cannot be used to enhance punishment for a subsequent offense. (Allen, supra, 21 Cal.4th at p. 429, 87 Cal.Rptr.2d 682, 981 P.2d 525 ; Garcia, supra, 14 Cal.4th at p. 959, 59 Cal.Rptr.2d 858, 928 P.2d 572.) But a section 1170.126 proceeding is not a "plenary resentencing proceeding" (People v. Bradford (2014) 227 Cal.App.4th 1322, 1336, 174 Cal.Rptr.3d 499 (Bradford )) and cannot result in enhancement of a sentence. "A finding an inmate is not eligible for resentencing under section 1170.126 does not increase or aggravate that individual's sentence; rather, it leaves him or her subject to the sentence originally imposed." (People v. Osuna (2014) 225 Cal.App.4th 1020, 1040, 171 Cal.Rptr.3d 55 (Osuna ).) Section 1170.126"merely provides a limited mechanism within which the trial court may consider a reduction of the sentence below the original term[,]" and "the potential reduction of the sentence is narrowly circumscribed by the statute." (Bradford, at p. 1336, 174 Cal.Rptr.3d 499, italics added.) The time for appellant to challenge the validity of the 1974 prior was when it was used to aggravate his sentence in 1985 and in 1997, which he did, unsuccessfully. Nothing in section 1170.126 authorizes a collateral attack on a prior strike conviction.

People v. Brown (2014) 230 Cal.App.4th 1502, 179 Cal.Rptr.3d 420 (Brown ) is instructive. In that case, the inmate seeking resentencing pursuant to section 1170.126 asked the trial court to exercise its discretion under section 1385 to strike the prior conviction that rendered him ineligible for resentencing—an argument appellant makes as well. Noting the general rule that a trial court lacks jurisdiction to resentence a defendant after execution of sentence has begun, the Brown court found nothing in the text of Proposition 36 to support the inmate's argument that the court had authority to strike the prior. (Brown , at pp. 1511–1513, 179 Cal.Rptr.3d 420.) " Section 1170.126 grants a trial court the power to determine an inmate's eligibility to be resentenced under the Reform Act only if the inmate satisfies the three criteria set out in subdivision (e) of the statute, as previously noted, and contains no provision authorizing a trial court to disregard the required criteria. (§ 1170.126, subd. (e).) Rather, the plain language of subdivision (e) clearly provides that an inmate must first satisfy each criteria set out in subdivision (e) of section 1170.126before he or she can be resentenced under the Reform Act, and gives the trial court no discretion to depart from the three-step requirement. In other words, if the inmate does not satisfy one or more of the criteria, section 1170.126 grants the trial court no power to do anything but deny the petition for recall of sentence." (Brown, at pp. 1511–1512, 179 Cal.Rptr.3d 420.)

Brown pointed out that section 1170.126, subdivision (f), gives the trial court discretion to deny resentencing if it determines that an eligible prisoner would pose an unreasonable risk of danger to public safety, but this discretion may be exercised "only after an inmate satisfies the [eligibility] criteria set out in subdivision (e), and only in determining whether granting that relief would pose an unreasonable risk of danger even if the petitioner satisfies the criteria in subdivision (e)." (Brown, supra, 230 Cal.App.4th at p. 1512, 179 Cal.Rptr.3d 420.) By contrast to the discretionary authority granted in subdivision (f), "the plain language of subdivision (e) of the statute authorizes no such discretionary power to a trial court in deciding an inmate's eligibility under the Reform Act." (Brown , at p. 1512, 179 Cal.Rptr.3d 420.) After reviewing the ballot materials concerning Proposition 36, which stated that "courts ‘conducting these resentencing hearings would first determine whether the offender's criminal history makes them eligible for resentencing’ " and nowhere stated "that a trial court has discretion to determine eligibility notwithstanding the [eligibility] criteria in subdivision (e) of section 1170.126," Brown concluded that it is "clear the electorate's intent was not to allow a trial court to retain its section 1385 discretionary authority when determining whether an inmate is eligible for resentencing under the Reform Act." (Brown , at p. 1514, 179 Cal.Rptr.3d 420, quoting Voter Information Guide, Gen. Elec. (Nov. 6, 2012), analysis of Prop. 36, by Legis. Analyst, at p. 50 (Voter Information Guide), italics in Brown .)

Similar reasoning applies where an inmate seeks to have a prior stricken for purposes of determining eligibility for resentencing on the ground that the prior is constitutionally invalid due to violation of his or her Boykin / Tahl rights. Section 1170.126 does not suggest a hearing is to be held on the question of a prisoner's eligibility for resentencing; it simply provides that "[u]pon receiving a petition for recall of sentence under this section, the court shall determine whether the petitioner satisfies the criteria in subdivision (e)." (§ 1170.126, subd. (f).) As relevant here, those criteria include the requirement that the inmate "has no prior convictions" for any of the specified offenses. (§ 1170.126, subd. (e)(3).) This language focuses on the fact of the prior conviction without suggesting its validity is subject to challenge. (See Custis, supra, 511 U.S. at pp. 490–491, 114 S.Ct. 1732.)

By contrast, section 1170.126 clearly contemplates a hearing on the matters to be determined after a petitioner is found eligible for resentencing (dangerousness and actual resentencing), as it authorizes the court to consider any evidence it finds relevant in deciding dangerousness (subd. (g)), allows the petitioner to "waive his or her appearance in court" for resentencing in certain circumstances (subd. (i)), and designates the "resentencing hearing" as a " ‘post-conviction release proceeding’ " for purposes of the state Constitution's provisions concerning crime victims' rights (Cal. Const. Art. I, § 28, subd. (b)(7)). (See Kaulick, supra, 215 Cal.App.4th at pp. 1296–1300, 155 Cal.Rptr.3d 856.)

As nothing in the text of Proposition 36 or ballot materials suggests the trial court has authority to conduct a hearing on the constitutionality of an inmate's disqualifying prior convictions, we see no basis for inferring that the voters intended to authorize such collateral attacks.

The focus of the ballot materials explaining Proposition 36 was on a defendant's new offense: The question was whether a life sentence would continue to be required whenever a defendant with two or more violent or serious felony convictions sustained a new felony conviction, or only when the new conviction was for a violent or serious felony. The ballot materials emphasized that life sentences would be maintained "for felons with nonserious, non-violent third strikes if prior convictions were for rape, murder or child molestation" and, with respect to resentencing, that due to the eligibility requirements, defendants with particularly serious criminal histories—"such as certain drug-, sex-, and gun-related felonies"—would remain subject to a life sentence. (Voter Information Guide, supra, analysis of Prop. 36, at p. 50.) Since the measure aimed to lessen sentences for defendants whose new convictions were for non-violent and non-serious felonies while preserving lengthy sentences based on criminal history, we see no reasonable basis for assuming the electors intended to provide previously sentenced defendants with a new means to challenge their past convictions.

Appellant's argument that the court was required to determine the constitutional validity of the 1974 prior in order to determine whether that prior made appellant ineligible for resentencing is based on his assumption that this use of the prior is "no different" than when the prosecution alleges a defendant is ineligible for probation due to a prior conviction, or is eligible for a second or third strike sentence due to a prior conviction. In those situations, appellant argues, if the defendant challenges the constitutionality of the prior, the court must determine its validity. While this is not true for every assertion of constitutional infirmity (see Garcia, supra, 14 Cal.4th at p. 966, 59 Cal.Rptr.2d 858, 928 P.2d 572 [no challenge to prior conviction on ground of ineffective assistance of counsel in current prosecution for noncapital offense] ), it is true for the Boykin / Tahl violation alleged here. (Allen, supra, 21 Cal.4th at pp. 427, 443, 87 Cal.Rptr.2d 682, 981 P.2d 525.) But the fact that a defendant has a right to challenge the constitutionality of a prior conviction alleged to enhance his or her sentence in a current proceeding does not necessarily mean the same right exists on a motion for resentencing. Various cases have recognized substantive and procedural differences between initial three strikes sentencing under the Reform Act and resentencing under section 1170.126. (E.g, Yearwood, supra, 213 Cal.App.4th at p. 178, 151 Cal.Rptr.3d 901 [no equal protection violation in provision for denial of resentencing on basis of dangerousness with no dangerous inquiry at original sentencing]; People v. Losa (2014) 232 Cal.App.4th 789, 793, 181 Cal.Rptr.3d 682 (Losa ) [same]; Osuna, supra, 225 Cal.App.4th at pp. 1033, 1038, 171 Cal.Rptr.3d 55 [unlike original sentencing, no pleading and proof requirement for disqualifying factors at resentencing and no requirement that disqualifying factors be proven to jury beyond reasonable doubt].) As we have said, the fundamental premise of appellant's argument—that a constitutionally invalid prior conviction cannot be used to enhance punishment for a subsequent offense (Allen, supra, 21 Cal.4th at p. 429, 87 Cal.Rptr.2d 682, 981 P.2d 525 ; Garcia, supra, 14 Cal.4th at p. 959, 59 Cal.Rptr.2d 858, 928 P.2d 572 )—does not apply to a section 1170.126 proceeding, which cannot increase an individual's sentence but only reduce or leave intact the sentence originally imposed. (Osuna, at p. 1040, 171 Cal.Rptr.3d 55 ; Bradford, supra, 227 Cal.App.4th at p. 1336, 174 Cal.Rptr.3d 499.)

The requisite authority to entertain a collateral attack on a prior conviction in this context is not conferred upon the trial court by Allen and Sumstine . The decision in Sumstine, supra, 36 Cal.3d 909, 206 Cal.Rptr. 707, 687 P.2d 904, permitting Boykin / Tahl challenges to prior convictions by motion to strike in a current sentencing proceeding, was based not on "constitutional imperatives" but on a "policy judgment" concerning "efficient judicial administration." (Allen, supra, 21 Cal.4th at p. 435, 87 Cal.Rptr.2d 682, 981 P.2d 525.) The administrative efficiency achieved by permitting the motion to strike was by comparison to the prior procedure, under which a defendant would "challenge a prior by seeking a writ of habeas corpus after a final judgment in which the prior had been used to enhance his sentence." (Sumstine, at p. 920, 206 Cal.Rptr. 707, 687 P.2d 904 ; Allen, at pp. 429–430, 87 Cal.Rptr.2d 682, 981 P.2d 525.) In other words, the collateral attack permitted by Allen and Sumstine allows a defendant who would be able to attack his or her sentence by habeas petition after judgment to make the challenge at the outset, before sentence is imposed. This rationale simply does not apply to a section 1170.126 proceeding taking place many years after the trial in which sentence was enhanced by a prior that is no longer subject to challenge.

The 1974 prior appellant sought to challenge in this resentencing proceeding had previously been used twice to enhance appellant's sentence for another crime. He challenged its constitutionality on the grounds now asserted by a motion to strike at his 1985 trial and again by writ petition after his 1997 conviction, based on his attorney's failure to challenge the prior in those proceedings. As we have said, his claim that the writ petition was denied in error (because this court mistakenly expected Allen to overrule Sumstine ) is speculative. The California Supreme Court denied review of the writ petition a week before the Allen opinion was issued, and we denied the request for reinstatement of the petition that appellant filed after Allen was decided. Appellant filed a petition for writ of habeas corpus in federal district court, the denial of which was affirmed by the Ninth Circuit Court of Appeal. Given these many levels of review, appellant's claim that he was not given a fair opportunity to challenge the 1974 prior is not persuasive. In addition to the proceedings subsequent to his 1997 conviction, appellant's Boykin - Tahl challenge was rejected by the Fifth District Court of Appeal after his 1985 conviction, and the California Supreme Court denied review of that decision. Appellant's argument that the Fifth District's decision was wrong comes too late and, in any event, does not confer authority not otherwise extended under section 1170.126 for the trial court to determine the constitutionality of the 1974 prior. Absent statutory authority, to allow an inmate seeking resentencing under section 1170.126 to challenge a disqualifying prior as having been obtained in violation his or her constitutional rights would permit "an end run around statutes of limitations and other procedural barriers that would preclude the movant from attacking the prior conviction directly." (Daniels v. U.S. (2001) 532 U.S. 374, 383, 121 S.Ct. 1578, 149 L.Ed.2d 590.)
