Because the California Supreme Court set out to create a rule that would be consistently applied, however, it does not follow that the rule in historical fact has been so applied. A few district courts have had the opportunity to analyze the consistency of application of the Clark rule, reaching opposing results. See, e.g., Deere v. Calderon,890 F.Supp. 893 (C.D.Cal.1995) (concluding that the Clark rule has been consistently applied *577 in capital cases); Coleman v. Calderon, No. C 89-1906 RMW,1996 WL 88882 , at *3 (N.D.Cal.1996) (holding that there is a “genuine question about whether California has applied [the Clark ] rule .consistently and regularly”), aff'd on other grounds,150 F.3d 1105 (9th Cir.), rev’d on other grounds,525 U.S. 141 ,119 S.Ct. 500 ,142 L.Ed.2d 521 (1998).

Thus, it was inappropriate for the district court to rely on Deere for two reasons: first, Deere analyzed the application of California’s procedural bar only in capital habeas cases,890 F.Supp. at 899 , while Bennett involves a noncapital habeas case. California’s rules governing timeliness in capital cases differ from those governing noncapital cases, id. at 897 (quoting California Supreme Court Policies Regarding Cases Arising From Judgments of Death, Timeliness Standards).[ FN2 ] Second, the Deere district court followed a procedure in analyzing the question that is inconsistent with our precedent; it analyzed the basis for the state court decisions denying post-conviction relief based on a post hoc examination of the pleadings and record rather than the text of the state court opinions. While we have not decided, and do not decide this precise issue in this context, our precedent suggests any review should be limited to the language of the state court opinions. See, e.g., Valerio v.

OPINION
Joseph Murl Bennett appeals the district court’s order adopting the Magistrate Judge’s Report and Recommendation denying his Petition for Writ of Habeas Corpus on the state procedural ground of untimeliness. We must decide whether the district court erred in concluding that the
*578
California Supreme Court’s denial of Bennett’s petition “on the merits and for lack of diligence” constituted an independent and adequate state ground so as to render his habeas petition procedurally defaulted. In so doing, we must determine whether the state court’s reliance upon
In re Clark,
I. Background
In 1986, Bennett pled guilty to first-degree burglary in Los Angeles Superior Court Case No. A468635. In the guilty plea form, signed by Bennett and his counsel, Bennett acknowledged: “I understand the court may send me to state prison for a maximum of 6 years.” The plea agreement further provided:
“If defendant pleads in case # A470545 and # A470930, this case will be 16 months consecutive to any sentence in those cases.”
At sentencing, Bennett attempted to withdraw his guilty plea and enter a plea of not guilty. He claimed it was his understanding, although his memory was, admittedly, “very vague,” that he was to receive 16 months on this case regardless of whether he pled guilty in the two other cases. The trial court denied Bennett’s motion and, finding the aggravating circumstances of his crime (a nighttime residential burglary) substantial, sentenced him to a prison term of six years. The trial court clarified that the other two cases remained pending; therefore, an open plea remained if he wished to plead guilty to the other cases.
Refusing to plead guilty to the remaining cases, Bennett requested a jury trial, thus terminating his plea agreement. He was convicted by jury in consolidated case Nos. A470545 and A470930 of two counts of first-degree burglary, forcible rape, forcible oral copulation, forcible sexual penetration with a foreign object, sodomy by force, and assault to commit rape. Bennett’s combined sentence totaled forty-two years and four months, which was later reduced by one year, making his total term forty-one years and four months.
Bennett did not pursue a direct appeal after his guilty plea and conviction in 1986. Instead, twelve years after his conviction, in 1998, he filed a “Motion for Transcripts” in the California Superior Court, arguing that he was improperly sentenced. The Superior Court denied the motion, finding that his contention “was raised, discussed, ... resolved ... [and] without merit.” Bennett later filed a Petition for Writ of Habeas Corpus in the Superior Court, which was denied as showing no grounds for relief. He next filed a Petition for Writ of Habeas Corpus in the same case with the California Court of Appeal, which, on May 25, 1999, denied the petition without comment or citation to authority. On July 8, 1999, Bennett filed a Petition for Writ of Habeas Corpus in the California Supreme Court, which, on November, 23, 1999, denied the petition “on the merits and for lack of diligence.”
*579 Bennett then filed this Petition for Writ of Habeas Corpus in the United States District Court. Bennett claims that (1) the trial court erred in failing to admonish him regarding the nature and effect of the plea agreement, rendering his guilty plea unknowing and involuntary; (2) the trial court abused its discretion in failing to reasonably consider the motion to withdraw his plea; and (3) his trial counsel was ineffective at the taking of and motion to withdraw the plea, and in failing to appeal. Respondents brought a motion to dismiss for procedural default, which Bennett opposed. The magistrate judge issued a Report and Recommendation, recommending that the district court deny and dismiss the petition with prejudice. On June 5, 2000, the district court adopted the Report and Recommendation and entered judgment denying and dismissing the petition with prejudice. On June 15, 2000, Bennett filed a notice of appeal and request for certificate of appealability in the district court. The district court denied the request. A motions panel of this court then granted a certificate of appealability on the question whether the state court’s citation to Clark and Robbins constituted an independent and adequate state bar so as to render the petition procedurally defaulted.
II. Procedural Default
Bennett argues that the district court erroneously concluded that his date of default occurred after the decisions of
Clark
and
Robbins.
Bennett asserts that because he was convicted in 1986, before the decisions issued in 1993
(Clark)
and 1998 (Robbins), the untimeliness rule created by those decisions cannot apply to him. The cases Bennett cites, however, do not stand for this proposition. Rather, the common theme of these cases is that when the habeas proceeding has been initiated before the Clark/Robbins decisions were announced, the untimeliness rule cannot stand as an independent and adequate state ground barring federal habeas review.
See, e.g., Fields v. Calderon,
This is not a case in which the petitioner filed his state habeas petition before or very shortly after the
Clark
decision was announced.
Cf. Bean,
The California Supreme Court has long required that a petitioner in a habeas corpus proceeding justify any substantial delay in seeking relief.
In re Stankewitz,
Bennett next argues that the state court’s citation to
Clark
and
Robbins
did not constitute an independent and adequate state ground so as to render his habeas petition proeedurally defaulted. Although none of the California decisions actually cited to
Clark
or
Robbins,
we have previously held that the California Supreme Court’s denial of a habeas petition, citing only “lack of diligence,” is an application of the untimeliness bar.
La Crosse v. Kernan,
Federal courts “will not review a question of federal law decided by a state court if the decision of that court rests on a state law ground that is independent of the federal question and adequate to support the judgment.”
Coleman v. Thompson,
“For the procedural default rule to apply, however, the application of the state procedural rule must provide ‘an adequate and independent state law basis’ on which the state court can deny relief.”
Park v. California,
Because we conclude that the state procedural ground of untimeliness was invoked even without direct citation to Clark and Robbins, we next consider whether reliance on these cases constitutes an independent and adequate state ground barring federal habeas relief.
*581 III. Independence
We conclude that because the California untimeliness rule is not interwoven with federal law, it is an independent state procedural ground, as expressed in
Clark/Robbins.
“For a state procedural rule to be ‘independent,’ the state law basis for the decision must not be interwoven with federal law.”
La Crosse,
The California Supreme Court has explained that the untimeliness rule requires that a petitioner in a habeas corpus proceeding justify any substantial delay in seeking relief.
In re Stankewitz,
On August 3, 1998, in
Robbins,
the California Supreme Court made clear that it would no longer consider federal law in denying a petition on untimeliness grounds. It recognized that, when reviewing state habeas petitions for the untimeliness ground embodied in
Clark
(as well as for distinct procedural grounds embodied in
Ex Parte Dixon,
[W]e shall assume, for the purpose of addressing the procedural issue, that a federal constitutional error is stated, and we shall find the exception inapposite if, based upon our application of state law, it cannot be said that the asserted error ‘led to a trial that was so fundamentally unfair that absent the error no reasonable judge or jury would have convicted the petitioner.’
*582
Id.
at 811-812,
[Wjhenever we apply the first three Clark exceptions, we do so exclusively by reference to state law. When we apply the fourth Clark exception, we apply federal law in resolving any federal constitutional claim.
Robbins,
We have since held that a California court’s
pre-Robbins
denial of a state habe-as petition for a
Dixon
violation does not bar subsequent federal review, and that the state court’s discussion of the
Dixon
rule should apply equally to the
Clark
untimeliness rule.
Park,
We declined to determine in
Park
“whether
Robbins
establishes the independence of California’s
Dixon
rule for the future.”
Park,
The California Supreme Court has adopted in Robbins a stance from which it will now decline to consider federal law when deciding whether claims are procedurally defaulted.... The purpose of this approach was to establish the adequacy and independence of the State Supreme Court’s future Dixon/Robbins rulings and to indicate that a prisoner seeking collateral relief with respect to new federal claims no longer had any recourse to exhaust in the state courts.... Robbins is clear, however, that its new approach is prospective.
Id. at 1152-53,1152 n. 4.
Moreover, Bennett’s claim that the interpretation of state constitutional principles and federal constitutional principles are necessarily intertwined is misguided. While it is true “that state courts will not be the final arbiters of important issues under the federal constitution; [it is equally true] that [the federal courts] will not encroach on the constitutional jurisdiction of the states.”
Minnesota v. Nat’l Tea Co.,
Therefore, we respect the California Supreme Court’s sovereign right to interpret its state constitution independent of the federal law. Applying Robbins prospectively, we affirm the district court’s determination that the California Supreme Court’s post-Robbins denial of Bennett’s state petition for lack of diligence (untimeliness) was not interwoven with federal law *583 and therefore is an independent procedural ground.
IV. Adequacy
Conversely, we cannot conclude, on the record before us, that the untimeliness rule is an adequate state procedural ground. To be deemed adequate, the state law ground for decision must be well-established and consistently applied.
Poland v. Stewart,
Before
Clark,
the California untimeliness standards were applied inconsistently to some fact patterns.
Clark,
Here, the district court observed that “California’s timeliness rule now appears to be ‘adequate.’ ” It based this conclusion almost entirely in reliance upon the
Deere
opinion, and its progeny. Thus, it was inappropriate for the district court to rely on
Deere
for two reasons: first,
Deere
analyzed the application of California’s procedural bar only in capital habeas cases,
Because there is a genuine question whether the untimeliness bar is adequate, and the record before us does not provide a means for answering this question, we must remand the question of adequacy of California’s untimeliness bar to the district court. There, the resolution of the issue may depend on the question of which party bears the ultimate burden of proof.
V. Burden of Proof
The district court concluded that Bennett bears the burden of establishing that the state procedural rule was not consistently and regularly applied, relying on
Wood v. Hall,
The Fifth Circuit has placed the burden upon the petitioner.
Sones v. Hargett,
In contrast, the Tenth Circuit employs a burden-shifting analysis that places the ultimate burden of proving the adequacy of a state procedural rule upon the state.
Hooks v. Ward,
Once the state pleads the affirmative defense of an independent and adequate state procedural bar, the burden to place that defense in issue shifts to the petitioner. This must be done, at a minimum, by specific allegations by the petitioner as to the adequacy of the state procedure. The scope of the state’s bur *585 den of proof thereafter will be measured by the specific claims of inadequacy put forth by the petitioner'.”
Hooks,
In
Hooks,
the court reasoned that “the state is undoubtedly in a better position to establish the regularity, consistency and efficiency with which it has applied [its procedural bar] than are habeas petitioners, who often appear pro se, to prove the converse.”
Hooks,
We prefer the approach outlined by the Tenth Circuit. Unlike the Fifth Circuit, we have never presumed the adequacy of a state procedural rule, but rather have examined whether the law has in fact been regularly and consistently applied. Moreover, there is good reason to place the burden of proving adequacy on the state, the most obvious of which is that procedural default is an affirmative defense.
Gray v. Netherland,
Although the burden of proving an affirmative defense is generally on the party asserting it, in this context, this placement is also the most just. It is the state, not the petitioner, often appearing pro se, who has at its hands the records and authorities to prove whether its courts have regularly and consistently applied the procedural bar.
See Hooks,
Thus, we conclude that the ultimate burden of proving the adequacy of *586 the California state bar is upon the State of California. This conclusion is not inconsistent with our holding in Wood that the petitioner there had not put forth sufficient evidence of inconsistency. Once the state has adequately pled the existence of an independent and adequate state procedural ground as an affirmative defense, the burden to place that defense in issue shifts to the petitioner. The petitioner may satisfy this burden by asserting specific factual allegations that demonstrate the inadequacy of the state procedure, including citation to authority demonstrating inconsistent application of the rule. Once having done so, however, the ultimate burden is the state’s.
Accordingly, because it is the State who seeks dismissal based on the procedural bar, it is the State who must bear the burden of demonstrating that the bar is applicable — in this case that the state procedural rule has been regularly and consistently applied in habeas actions. Because neither the district court nor the parties could have anticipated this new standard, we remand for a fresh determination of the adequacy of the state ground in accordance with the rule we adopt today.
CONCLUSION
We conclude that the reference by the California Supreme Court to “lack of diligence” is a reference to untimeliness as discussed in Clark/Robbins and that since Robbins, “untimeliness” is an independent state ground. Whether it is also an adequate state ground must be determined by the district court upon remand under the burden of proof principles we have set forth today.
AFFIRMED in part; REVERSED in part; and REMANDED.
Notes
[FN2] This distinction was apparently missed by the district courts in
Allard v. Olivarez,
No. C 97-1009 FMS (PR),
. The fourth Clark exception, "that the petitioner was convicted or sentenced under an invalid statute,” has not been raised by Bennett and, thus, is not relevant to this case.
