John Lee Cook appeals the denial of his petition for a writ of habeas corpus. He contends that the district court should not have dismissed his petition as delayed and that the district court erred in finding that he had waived his objections to a prior conviction. He also asserts that his counsel was ineffective at his state trial. We reverse the judgment of the district court.
I.
On July 21, 1982, a jury found Cook guilty of the felony of indecency with a child. Cook then pled no contest to a 1964 conviction for the felony of burglary with intent to commit theft, which was used against him for enhancement. 1 The jury assessed his punishment at 20 years’ imprisonment. The Court of Appeals for the Eighth Supreme Judicial District of Texas affirmed Cook’s conviction on August 24, 1983, and the Texas Court of Criminal Appeals denied discretionary review.
In 1982, Cook filed two unsuccessful state habeas applications based on contentions unrelated to his present claim. In 1983, he filed another state habeas application, which the state court did not consider because his direct appeal was pending. In 1984, Cook filed a joint state habeas application alleging that the 1964 conviction used for enhancement was void because he was not represented by counsel when his probation was revoked. As case support, he relied on
Mempa v. Rhay,
Cook filed the present application for a writ of habeas corpus in federal district court. The state moved to dismiss the application as a delayed application under rule 9(a) of the Rules Governing Section 2254 Cases in the United States District Courts. The district court granted the state’s motion to dismiss, concluding that the state was prejudiced by the delay in filing because no transcript of the 1964 parole revocation hearing existed and because the district attorney who was present at the hearing had died. As an alternative basis for dismissal, the district court concluded that Cook had waived any error in the 1964 conviction by failing to challenge the conviction when it was used for enhancement. Cook appeals.
II.
Cook first argues that the district court improperly dismissed his petition under rule 9(a) as delayed. The state now concedes that dismissal under rule 9(a) was improper. To prevail on a claim of delay the state must make “a particularized showing of prejudice.”
Strahan v. Blackburn,
III.
Cook next asserts that the district court erred in concluding that he waived his objections to the 1964 conviction. The state’s arguments present two separate justifications for the district court’s ruling that Cook waived his objections. First, the state emphasizes that, at the enhancement phase of his 1982 trial, Cook pled “no contest” to the 1964 conviction when it was offered to support the enhancement count. The state asserts that Cook’s plea of no contest “waive[d] all non-jurisdictional defects in the proceedings.”
Johnson v. Estelle,
Cook argues in response that, because the Texas courts reviewing his claims on direct appeal and on petition for a state writ of habeas corpus addressed the merits of his argument that the 1964 conviction was void, instead of relying upon procedural default, the considerations of comity underlying the requirements of Wainwright v. Sykes are inapplicable, and the federal courts may likewise address the merits of his claim. Alternatively, Cook argues that Sykes’s requirements are satisfied in his case and the district court erred for that reason in refusing to address the merits of his claims. The ineffectiveness of his 1982 counsel in failing to investigate whether he was represented in 1964 constitutes “cause” under the first prong of the Sykes test, Cook asserts. Moreover, Cook points out that the enhancement count added to his sentence ten years above and beyond the maximum sentence that can be imposed for the offense of indecency with a child. Cook argues that these incremental years of imprisonment, which could not have been imposed had his 1982 counsel investigated and asserted the invalidity of the 1964 conviction, clearly constitute “preju *1075 dice” under the second prong of the Sykes test.
A.
For the purposes of section 2254 proceedings, “a guilty plea represents a break in the chain of events which has preceded it in the criminal process. When a criminal defendant has solemnly admitted in open court that he is in fact guilty of the offense with which he is charged, he may not thereafter raise independent claims relating to the deprivation of constitutional rights that occurred prior to the entry of the guilty plea.”
Tollett v. Henderson,
Our inquiry does not end there, however. A guilty plea is valid, and therefore acts as a waiver of prior constitutional infirmities, only if it was “voluntarily and intelligently entered.”
Henderson,
If a prisoner pleads guilty on the advice of counsel, he must demonstrate that the advice was not “within the range of competence demanded of attorneys in criminal cases,” McMann v. Richardson, [397 U.S. 759 ,] 771 [90 S.Ct. 1441 , 1449,25 L.Ed.2d 763 (1970) ]. Counsel’s failure to evaluate properly facts giving rise to a constitutional claim, or his failure properly to inform himself of facts that would have shown the existence of a constitutional claim, might in particular fact situations meet this standard of proof.
Henderson,
B.
According to the doctrine crystallized in
Wainwright v. Sykes,
Cook’s preliminary contention is that the Sykes doctrine does not apply in the instant *1076 case because the state courts did not rely upon his 1982 counsel’s failure to object to the introduction of the 1964 conviction, but instead addressed the merits of the 1964 conviction’s validity. In support of this contention, Cook points to the findings of fact in his favor made by the state district court after the evidentiary hearing on his 1983 joint state habeas petition. As previously noted, the Texas Court of Criminal Appeals denied his joint state habeas petition without written order or hearing based upon the findings of the district court.
To determine the basis for a state court’s denial of habeas relief when the state court does not state its reasons, the federal courts look to the following considerations:
whether the state court has used procedural default in similar cases to preclude review of the claim’s merits, whether the history of the case would suggest that the state court was aware of the procedural default, and whether the state court’s opinions suggest reliance upon procedural grounds or a determination of the merits.
Preston v. Maggio,
The Texas Court of Criminal Appeals in other cases has used the failure to object to proof of a prior conviction to preclude review of the merits.
Hill v. State,
Cook also points to language allegedly addressing the merits of his present claim in the opinion rendered on direct appeal of his conviction by the Court of Appeals for the Eighth Supreme Judicial District of Texas. A fair reading of the language in that opinion is that the Court of Appeals held that Cook’s claim was barred by procedural default, but that in any event a review of the merits of his claim, based on evidence improperly attached to his appellate brief, revealed no reversible error.

*1077
The rule in this circuit is that, when a state court bases its decision upon the alternative grounds of procedural default and a rejection of the merits, a federal court must, in the absence of good “cause” and “prejudice,” deny habeas relief because of the procedural default.
Ratcliff v. Estelle,
1.
The court below based its decision that Cook had failed to demonstrate “cause” under the
Sykes
standard on two alternative grounds. First, the district court seemed to interpret our decision in
Marks v. Estelle,
The district court decided Cook’s petition without the benefit of the Supreme Court’s recent decision in
Murray v. Carrier,
which held,
inter alia,
that “[ineffective assistance of counsel, then, is cause for a procedural default.”
*1078
According to the Supreme Court’s seminal decision in
Strickland v. Washington,
a defendant claiming ineffective assistance has the burden of demonstrating (1) that counsel’s performance was deficient, and (2) that the deficient performance prejudiced the defense.
The state correctly notes that the Constitution imposes no general, per se duty on counsel to investigate whether a defendant’s prior convictions were counseled.
See, e.g., Marks,
In the instant case, however, we have before us no “decision not to investigate” to assess. At the evidentiary hearing on Cook’s joint state habeas petition, Cook’s 1982 counsel forthrightly testified that it never “struck his mind” to investigate whether Cook’s 1964 conviction was assisted by counsel. Thus, rather than determine whether a strategic choice not to investigate the 1964 conviction “ ‘might be considered sound trial strategy,’ ”
id.
at 689,
We find that the facts of this case would have alerted a reasonably competent attorney to the need to investigate whether Cook’s 1964 conviction was counseled. Three factors are crucial to this determination. First, the “pen packet,” a dossier containing important documents relevant to a criminal conviction, sent to Cook’s attorney in advance of trial included a trial memo of the 1964 conviction. The trial memo is a form with blank spaces designated for the cause number, the defendant’s name, the name of defense counsel, the charge, the district attorney’s number, the trial date, the recommended sentence, and the witnesses to be called at the hearing. The 1964 trial memo was completely filled out, except that there was no indication that Cook had been represented by counsel. Second, the date of the conviction used for enhancement and the fact that it was entered at a probation revocation hearing are important to our decision. In 1964, it was clearly established under Texas law that an indigent defendant had no right to counsel at a parole revocation hearing.
See Ex parte Crawford,
The state contends that our decision in
Marks
controls the facts of the instant appeal and commands a different result. We find
Marks
to be clearly distinguishable. Unlike the instant case, in
Marks
no objective indicia were present that indicated that the earlier convictions were uncounseled.
Johnson v. Cabana,
also cited by the state, is equally inapposite.
2.
We find that Cook has unquestionably shown that he was prejudiced by his 1982 counsel’s failure to investigate whether the 1964 conviction was counseled. The state district court found that Cook was not represented by counsel at the 1964 parole revocation hearing, that he was indigent at that time, and that he did not know that he had a right to counsel at that hearing and did not knowingly waive his right to have counsel appointed to represent him. These findings establish that the 1964 conviction was void.
See Mempa v. Rhay,
In summary, Cook has demonstrated that, because of the constitutionally ineffective assistance of his counsel, his nolo contendere plea to the enhancement count was not voluntarily and intelligently entered, his failure to object to the validity of the 1964 conviction is excused by cause, and his counsel’s failure to investigate such validity has resulted in prejudice. The district court therefore erred in refusing to reach the merits of Cook’s claims.
IV.
The judgment of the district court is REVERSED and this case is REMANDED to the district court for further proceedings not inconsistent with this opinion.
Notes
. Cook pled guilty to the charge of burglary with intent to commit theft in 1963. The imposition and execution of his sentence were suspended at that time, and Cook was placed on probation for a period of five years by order of the sentencing court on September 25, 1963. Cook's probation was revoked and he was committed to confinement after a hearing held on February 20, 1964. Because, as counsel for the state assures us, Cook's conviction did not become final under Texas law until his probation was revoked in 1964, we refer herein to said conviction as the 1964 conviction.
. The Court of Appeals’ opinion reads, in pertinent part:
Ground of Error No. One alleges that the prior burglary conviction could not properly be utilized to enhance the present prosecution. It culminated in a revocation of probation at which Appellant, an indigent, was not represented by counsel. Appellant pled no contest to the enhancement allegation. A set of known fingerprints and a penitentiary packet were introduced without objection, establishing the enhancement allegations. Appellant offered no evidence. The original judgment granting probation reflects that Appellant was present with counsel. The later judgment revoking probation, included within the penitentiary packet, makes no mention of counsel. A silent judgment is insufficient to support an allegation of deprivation of counsel. Chancy v. State,614 S.W.2d 446 , 447 n. 1 (Tex.Crim.App.1981); Ex parte Swinney,499 S.W.2d 101 (Tex.Crim.App.1973). The exhibits attached to Appellant’s brief are not properly before this Court. Even if they were, they fail to satisfy Appellant’s burden on this issue. Appellant has the burden to show that he was indigent, without counsel, and did not voluntarily waive counsel. Chancy at 447. The presumption of regularity applies in this case as in Chancy. See also: Ex parte Sanders,588 S.W.2d 383 (Tex.Crim.App. 1979) [ (failure to object to proof of a void conviction constitutes a waiver of the claimed right) ]. Ground of Error No. One is overruled.
Cook v. State, No. 08-82-00239-CR, slip op. at 1-2 (Tex.App. — El Paso Aug. 24, 1983, pet. refd) (unpublished opinion). Even if we were to conclude that procedural default was not established by the Court of Appeals’ notation that Cook failed to object to the admission of the 1964 conviction, that he pled no contest to such conviction, and that the contemporaneous objection rule of Ex parte Sanders was applicable *1077 to the facts sub judice, we would still be confronted with significant concerns of comity similar to those addressed in Sykes: to wit, what is the appropriate role of the federal court when an intermediate state court has addressed petitioner’s constitutional claim but the highest state court has issued a ruling that can only be interpreted as based upon procedural default? Because we hold infra that Cook has satisfied the "cause" and "prejudice” requirements of Sykes, we would not be required to decide that difficult question in the instant case at any rate.
. The
Marks
court, as noted by the court below, relied upon language from another decision of this court that, at first blush, seems to foreclose absolutely the assertion of ineffective assistance as a
Sykes
"cause”: " ‘[t]his assertion ... would effectively eliminate any requirement of showing cause at all. If a petitioner could not demonstrate any legitimate cause, he would only have to raise the spectre of ineffective assistance of counsel to get his challenge heard. This we refuse to sanction.’”
