Opinion by Judge REINHARDT; Concurrence by Judge BROWNING.

Introduction

This case forces us to attempt to make some sense of the procedural morass that surrounds habeas corpus. In all three cases, a United States magistrate presided over voir dire without the consent of the defendants. While the cases were still pending on direct appeal, the Supreme Court in Gomez v. United States, 490 U.S. 858 , 109 S.Ct. 2237 , 104 L.Ed.2d 923 (1989), held that it is per se reversible error for a magistrate to preside over jury selection in a felony trial without the defendant’s consent. Subsequently, each defendant sought review in the Supreme Court, but none of the petitions for certiorari raised a Gomez claim. Instead, the defendants’- attorneys chose to pursue the issue in petitions for collateral relief under 28 U.S.C. § 2255 . Although the petitioners would clearly prevail on the merits, the government argues that we must overlook the reversible error that transpired simply because their attorneys raised their Gomez claims in § 2255 rather than certiorari petitions. Because, under the law of this circuit (at least as of the time of the purported procedural defaults in this case), there was no rule requiring the petitioners to raise their Gomez claim on direct appeal, we must reach the merits of their petitions. Accordingly, we reverse the judgments of the district court which rejected English’s and *475 Tano’s petitions, and we affirm the judgment of the district court which granted Davis’s petition.

Facts

In this consolidated appeal, English and Tano appeal from the judgment of the district court (per Judge Tashima) which denied their § 2255 petitions. The government appeals from the judgment of the district court (per Judge Rosenblatt) which granted Davis’s § 2255 petition.

A. English v. United States, No. 91-16442

Tano v. United States, No. 91-16500

In February of 1988, Patrick English and Derek Tano were tried on cocaine distribution and conspiracy charges in the United States District Court for the District of Hawaii. A federal magistrate presided over the selection of the jury for the defendants’ trial, a practice which we had previously upheld on at least two occasions. See United States v. Peacock, 761 F.2d 1313 (9th Cir.), cert. denied, 474 U.S. 847 , 106 S.Ct. 139 , 88 L.Ed.2d 114 (1985); United States v. Bezold, 760 F.2d 999 (9th Cir.1985), cert. denied, 474 U.S. 1063 , 106 S.Ct. 811 , 88 L.Ed.2d 786 (1986). Neither English nor Tano objected to the magistrate’s role in the voir dire procedure. The defendants were each convicted on one count. The district court sentenced English to eight years imprisonment and Tano to three years.

English and Tano both took direct appeals from the district court’s judgment. However, their briefs on appeal did not assert that the district court erred by allowing the magistrate to preside over voir dire. In an unpublished memorandum, this court affirmed English and Tano’s convictions on May 12, 1989. One month later, on June 12,1989, the Supreme Court held in Gomez that it is per se reversible error for a magistrate to preside over jury selection in a felony trial. English filed a petition for certiorari in the Supreme Court on July 7, 1989, and Tano filed a certiorari petition on July 21. Neither petition raised the Gomez issue, and both petitions were denied in early October.

On September 29, 1989, while his petition for certiorari was pending, English filed a motion raising the Gomez claim in the district court under 28 U.S.C. § 2255 . On October 10, the district court issued an order staying English’s § 2255 proceedings pending completion of his direct appeal. The order stated:

When the district court filed its order, it was understandably unaware that the Supreme Court had just denied English’s petition for certiorari.

On October 31, 1989, Tano filed a § 2255 petition which raised the Gomez claim. Adhering to a procedure similar to the one it had followed in addressing English’s petition, the district court entered an order holding Tano’s § 2255 proceedings in abeyance pending the completion of his direct appellate remedies. Specifically, the district court ordered Tano to file in this court a motion to recall the mandate in his direct appeal:

Neither English nor Tano filed a motion to recall the mandate in this court. 1

*476 The district court deferred submission of English’s and Tano’s petitions pending the Supreme Court’s decisions in United States v. France, 498 U.S. 335 , 111 S.Ct. 805 , 112 L.Ed.2d 836 (1991) (per curiam) (affirming by an equally divided Court), and Peretz v. United States, 501 U.S. 923 , 111 S.Ct. 2661 , 115 L.Ed.2d 808 (1991). On September 9, 1991, it denied both petitions. See United States v. English, 777 F.Supp. 791 (D. Hawaii 1991). The district court held that English and Tano had defaulted on their Gomez claims by failing to object to the voir dire procedure at trial, on direct appeal, or in a motion to recall the mandate. It further held that the petitioners had shown neither cause nor prejudice to excuse those defaults. English and Tano filed timely appeals.

B. United States v. Davis, No. 92-15368

In January of 1988, Lutrell Davis was tried in the United States District Court for the District of Hawaii, on charges of mailing threatening communication and threatening to assault or murder a federal judge. A federal magistrate presided over jury selection, and Davis did not raise any objection to the procedure. The jury convicted Davis, and the district court sentenced him to 20 years imprisonment.

Davis appealed, but he did not claim on appeal that the district court erred in allowing the magistrate to preside over voir dire. On May 31, 1989, this court affirmed Davis’s conviction. See United States v. Davis, 876 F.2d 71 (9th Cir.1989). Less than two weeks later, on June 12, 1989, the Supreme Court issued its decision in Gomez . Davis filed a petition for certiorari on July 31, 1989. His petition did not contain a Gomez claim. The Supreme Court denied the writ of certiorari on October 2, 1989.

On September 29, 1989, before the Supreme Court had denied his petition for cer-tiorari, Davis filed in the district court a motion for a new trial under 28 U.S.C. § 2255 . He alleged that the district court had committed reversible error by delegating jury selection in his case to a federal magistrate. 2 The district court granted Davis’s petition on January 17, 1992. It held that Davis’s failure to raise the Gomez claim on direct review or in a motion to recall the mandate was excused because (1) a consistent line of Ninth Circuit authority prior to Gomez made any objection to the voir dire procedure futile; (2) Davis could not have raised this issue for the first time in his petition for certiorari; and (3) this court’s procedures following the Loma Prieta earthquake prevented Davis from moving to recall the mandate. The district court also held that the procedural default rules set forth in United States v. Frady, 456 U.S. 152 , 102 S.Ct. 1584 , 71 L.Ed.2d 816 (1982), do not apply here, because Davis filed his § 2255 petition before his conviction was final on direct appeal. The government filed a timely appeal.

Discussion

The claim asserted by English, Tano, and Davis is a simple one: that the district court committed reversible error by allowing a magistrate judge to preside over voir dire at their trials without their consent. After Gomez , this claim is clearly meritorious. If we may reach the merits of the claim, we must direct the district court to vacate the verdicts and grant English, Tano, and Davis new trials. The government does not contest these facts. 3 The government simply argues that the defendants procedurally defaulted their Gomez claims when their attorneys decided to raise the claims in the district court on motions for § 2255 relief, rather than raising them for the first time in petitions for certiorari in the Supreme Court or in motions to recall the mandate. The government further contends that English, Tano, and Davis have not shown cause and prejudice to excuse their purported defaults, and thus *477 that the district court had no discretion to consider their claims. We conclude that English, Taño, and Davis did not default on their claims. There was thus no need for them to show cause and prejudice.

A. Legal Standard,

Although the petitioners and the government have largely framed their arguments around the question whether cause and prejudice exists for the petitioners’ failure to raise their Gomez claims on direct review, we must first face an antecedent, question: whether the failure to raise the claims constituted a procedural default. Only if English, Taño, and Davis defaulted on their claims can we require them to show cause and prejudice.

A prisoner defaults on a claim only when he fails to comply with an applicable procedural rule. The cases discussing procedural default in the context of federal habeas corpus for state prisoners (in which the procedural default doctrine has mainly developed) make this point clear. As the Supreme Court explained in Coleman v. Thompson, 501 U.S. 722 , 111 S.Ct. 2546 , 115 L.Ed.2d 640 (1991), in the § 2254 context the procedural default doctrine is merely a specific application of the general adequate and independent state grounds doctrine. See id. at 729-31, 111 S.Ct. at 2554. Thus, a federal habeas court will find a default in a § 2254 case — and apply the cause and prejudice standard — only if “the petitioner failed to follow applicable state procedural rules in raising the claims.” Sawyer v. Whitley, — U.S. -, -, 112 S.Ct. 2514, 2518 , 120 L.Ed.2d 269 (1992).

Absent a state procedural rule which requires a defendant to raise a particular claim under penalty of default, federal courts in § 2254 proceedings will not find a procedural bar simply because the petitioner failed to raise the claim at trial or on appeal. For example, in Reed v. Ross, 468 U.S. 1 , 104 S.Ct. 2901 , 82 L.Ed.2d 1 (1984), the Supreme Court refused to find that the petitioner had procedurally defaulted on a challenge to his jury instructions simply because he failed to object at trial. The Court explained that “under North Carolina law at the time, a contemporaneous objection at trial was not necessary to preserve for review a question involving jury instructions.” Id. at 7 n. 4, 104 S.Ct. at 2906 n. 4. Similarly, in Maxwell v. Sumner, 673 F.2d 1031 (9th Cir.), cert. denied, 459 U.S. 976 , 103 S.Ct. 313 , 74 L.Ed.2d 291 (1982), we refused to apply the cause and prejudice standard when there was no state rule which required the defendant to raise his claim on direct appeal to the state supreme court. In a scholarly and thorough opinion authored by Judge Norris, we explained that it is only the violation of a state procedural rule, and not the mere failure to raise a claim, that triggers the procedural default doctrine. See id. at 1033-34. The Seventh Circuit reduced this principle to a useful aphorism: “ ‘[PJrocedural default’ requires the by-pass of a procedural requirement, and not merely the by-pass of a procedural opportunity.” Brownstein v. Director, Illinois Department of Corrections, 760 F.2d 836 , 841 n. 2 (7th Cir.) (citing Maxwell with approval), cert. denied, 474 U.S. 858 , 106 S.Ct. 166 , 88 L.Ed.2d 138 (1985).

The same principle applies in § 2255 eases. Unless the defendant has violated some rule which required him to raise a claim or forfeit it, there is no procedural default, and the cause and prejudice standard does not apply. This point is clear from an examination of the only two § 2255 cases in which the Supreme Court has ever invoked the cause and prejudice requirement. See United States v. Frady, 456 U.S. 152 , 102 S.Ct. 1584 , 71 L.Ed.2d 816 (1982); Davis v. United States, 411 U.S. 233 , 93 S.Ct. 1577 , 36 L.Ed.2d 216 (1973). In each of these cases, the Court found a procedural default and applied the cause and prejudice standard only after the defendant had violated a specific procedural rule by failing to raise his claim. In Frady , the petitioner alleged that the trial court had erroneously instructed the jury on the question of malice. He raised this claim for the first time in his § 2255 motion. Because Frady failed to comply with Rule 30 of the Federal Rules of Criminal Procedure, which required a party to raise any objections to jury instructions “before the jury retires to consider its verdict,” the Supreme Court held that he had procedurally defaulted his claim. See Frady, *478 456 U.S. at 162-64 , 102 S.Ct. at 1591-93 . The Court’s decision in Frady rested on the application of Rule 30’s specific procedural requirement. Only after the defendant violated that requirement did the Supreme Court find a procedural default. 4

In Davis, the Supreme Court made even more clear that it was the defendant’s violation of a specific procedural rule — and not his mere failure to raise a claim — that compelled the finding of a procedural default. In his § 2255 proceeding, Davis alleged for the first time that African-Americans had been systematically excluded from the grand jury which indicted him. Because Rule 12(b)(2) of the Federal Rules of Criminal Procedure provided that “objections based on defects in the institution of the prosecution or in the indictment” must be raised “by motion before trial” on penalty of waiver, the Supreme Court held that Davis had defaulted his claim. See Davis, 411 U.S. at 236-38 , 93 S.Ct. at 1579-81 . Then-Justice Rehnquist’s opinion for the Court expressly distinguished Kaufman v. United States, 394 U.S. 217 , 89 S.Ct. 1068 , 22 L.Ed.2d 227 (1969). In Kaufman , the Court had held that § 2255 relief is available to prisoners raising constitutional claims — whether or not they asserted those claims on direct review — unless the defendant deliberately bypassed prior opportunities to raise the claim. See id. at 220 n. 3, 223, 89 S.Ct. at 1070 -71 n. 3, 1072. The Davis Court noted that Kaufman’s Fourth Amendment claims were not subject to the cause and prejudice requirement because, unlike Davis’s challenges to the composition of his grand jury, search and seizure claims are not subject to “the sort of express waiver provision contained in Rule 12(b)(2) which specifically provides for the waiver of a particular kind of constitutional claim if it is not timely asserted.” Davis, 411 U.S. at 239-40 , 93 S.Ct. at 1581 .

As Davis makes clear, the cause and prejudice standard is limited to cases in which the petitioner has defaulted a claim by failing to comply with some procedural rule. Moreover, it is important to note that the procedural rule must have been in existence at the time of the alleged default. If the petitioner’s failure to raise a claim did not violate any then-existing rule, he did not commit a procedural default, and the cause and prejudice standard does not apply. See Sanchez v. United States, 782 F.2d 928 , 935 n. 3 (11th Cir.1986); see also Reed v. Ross, 468 U.S. at 7 n. 4, 104 S.Ct. at 2905 -06 n. 4 (refusing to find a procedural default in a § 2254 case, despite the petitioner’s failure to raise a claim on direct review, because “under North Carolina law at the time, a contemporaneous objection at trial was not necessary” to preserve the issue for review) (emphasis added). As the Supreme Court explained most recently in Ford v. Georgia, 498 U.S. 411 , 111 S.Ct. 850 , 112 L.Ed.2d 935 (1993), it is grossly unfair — and serves none of the purposes of respect for procedural rules — to forfeit an individual’s constitutional claim because he failed to follow a rule that “was not firmly established at the time in question.” Id. at 425 , 111 S.Ct. at 858. Before we can consider whether English, Taño, and Davis have shown cause and prejudice, the government must point us to some firmly established procedural rule which required them to raise their Gomez claim at trial or on direct review.

B. Analysis

The government asserts that English, Taño, and Davis each committed two procedural defaults — first by failing to object in the trial court to the magistrate’s presiding over voir dire, and second by failing to assert *479 this claim on direct appeal prior to our denial of the petition for rehearing, in the petition for certiorari in the Supreme Court, or in a subsequent motion to recall the mandate. However, we conclude that the petitioners did not violate any procedural rule which was in effect at the time of these purported defaults. We will address each purported default in turn.

1. Failure to Object in the Trial Court

We conclude that the petitioners’ failure to object in the trial court to the voir dire procedure did not constitute a procedural default. English, Taño, and Davis’s trials all took place before Gomez was decided. As we explained in France , any objection at the time of their trials would have been futile, because “a ‘solid wall of circuit authority”’ prior to Gomez had held that it was not error for magistrates to conduct voir dire in felony trials. France, 886 F.2d at 228 (quoting Guam v. Yang, 850 F.2d 507 , 512 n. 8 (9th Cir.1988) (en banc); United States v. Scott, 425 F.2d 55, 57-58 (9th Cir.1970) (en bane)). Because it would be pointless (and indeed wasteful) to require a defendant to raise such a futile objection in the district court, we held in France that, at least in cases that were tried before Gomez was decided, a defendant did not forfeit a Gomez claim merely by failing to raise an objection in the trial court. See id. at 227-28. Accordingly, English, Taño, and Davis’s failure to object in the trial court does not prevent us from reaching the merits of their claims. 5

2. Failure to Raise the Claim on Appeal

We also conclude that English, Taño, and Davis did not commit a procedural default by failing to raise their claims on direct appeal prior to our denial of the petition for rehearing, in their petitions for certiorari in the Supreme Court, or in a subsequent motion in this court to recall the mandate. Initially, we note that the petitioners’ failure to raise their claims on direct appeal to this court is excused for the same reason as the failure to raise the claims in the trial court. We decided all of the petitioners’ direct appeals before the Supreme Court handed down its decision in Gomez . Thus, it would have been futile for English, Taño, and Davis to challenge the jury selection procedures on their direct appeals.

The only question we must face, then, is whether English, Taño, and Davis committed a procedural default by failing to raise their Gomez claims in petitions for certiorari or motions to recall the mandate in this court. We find no rule which required the petitioners to raise these claims in such a manner. (This is not surprising, because the filing of a petition for certiorari or a motion to recall the mandate is ordinarily unnecessary to exhaust one’s remedies). Moreover, we conclude that the petitioners did not deliberately bypass the available means of seeking relief on direct review.

At least as of 1989 (when the petitioners’ convictions became final), we adhered to the rule enunciated in Kaufman , that § 2255 relief “cannot be denied solely on the ground that relief should have been sought by appeal to prisoners alleging constitutional deprivations.” Kaufman, 894 U.S. at 223, 89 S.Ct. at 1072 . Under Kaufman , a federal prisoner’s failure to raise a constitutional claim on direct appeal does not constitute a procedural default unless it amounts to a “deliberate by-pass.” Id. at 220 n. 3, 89 S.Ct. at 1071 n. 3.Thus, it has been the general rule in this circuit that “constitutional claims may be raised in collateral proceedings even if the defendant failed to pursue them on appeal.” United States v. Schaflander, 743 F.2d 714, 717 (9th Cir.1984) (per curiam) (citing Davis v. United States, 417 U.S. 333 , 345 n. 15, 94 S.Ct. 2298 , 2305 n. 15, 41 L.Ed.2d 109 (1974); Marshall v. United States, 576 F.2d 160, 162 (9th Cir.1978)), cert. denied, 470 U.S. 1058 , 105 S.Ct. 1772 , 84 L.Ed.2d 832 (1985). 6

*480 We have recognized that Frady and Davis “carved out a class of constitutional claims” that are not subject to the general rule identified in Schaflander and Kaufman. United States v. Spawn Optical Research, Inc., 864 F.2d 1467, 1471 (9th Cir.1988). However, we have also noted that Frady and Davis by their terms apply only to claims “that run afoul of express waiver provisions.” Id.; see also United States v. Corsentino, 685 F.2d 48, 50 (2d Cir.1982) (“Frady, [Wainwright v. Sykes, and Sykess predecessors, Davis v. United States and Francis v. Henderson, 425 U.S. 586 , 96 S.Ct. 1708 , 48 L.Ed.2d 149 (1976), concerned the limited scope of collateral attack to raise errors that were required to have been asserted at or before trial by federal or state contemporaneous objection rules.”) (citations omitted). Where no procedural rule explicitly requires a constitutional claim to be raised at trial or on direct appeal, “we have ‘not held that the mere failure to raise a constitutional claim on direct review constitutes a procedural default and thus prevents consideration of the issue in a collateral proceeding absent a showing of cause and prejudice.’ ” Chambers v. United States, 22 F.3d 939, 945 (9th Cir.1994) (quoting United States v. O’Mara, 827 F.Supp. 1468, 1472 (C.D.Cal.1993)). 7

To be sure, two of our cases have included language that could be read as suggesting that a procedural default occurs when a defendant fails to avail himself of an opportunity to raise a claim on appeal. See United States v. Dunham, 767 F.2d 1395 , 1397 & n. 2 (9th Cir.1985); Abatino v. United States, 750 F.2d 1442, 1445 (9th Cir.1985). However, these cases did not hold that the mere failure to raise a claim on direct review— absent a specific procedural rule which required the defendant to raise it — constitutes a procedural default. In fact, they dealt with precisely the same issue addressed in Fra-dy — whether a petitioner may raise a challenge to an erroneous jury instruction in a § 2255 proceeding, when he failed to object before the jury retired as required by Federal Rule of Criminal Procedure 30. In Abati-no, the petitioner’s § 2255 motion contended that the district court’s instructions had placed undue pressure on jurors to reach a fast verdict. Because the petitioner violated Rule 30 by failing to object to the jury instruction at trial, and then failed to allege plain error on direct appeal, we held that the cause and prejudice requirement applied to bar his claim. See Abatino, 750 F.2d at 1445 . 8 In Dunham , the petitioner claimed that a supplemental instruction given in response to an inquiry from the jury improperly directed a verdict against him on the mens rea element of his offense. See United States v. Dorri, 15 F.3d 888, 891 (9th Cir.1994) (applying Rule 30 in this situation). Although our opinion included language which could be construed as requiring the application of the cause and prejudice stan *481 dard applies whenever a petitioner fails to raise a claim at trial or on appeal, see Dunham, 767 F.2d at 1397 , our decision was again bottomed on the narrow rule announced in Frady — that the failure to object to a jury instruction as required by Rule 30 constitutes a procedural default which bars collateral review absent a showing of cause and prejudice. 9

At least as of 1989, then, this circuit applied the rule set forth in Kaufman , as embellished in Frady and Davis. 10 We imposed no general requirement that federal defendants raise constitutional claims on direct appeal. Only if the defendants deliberately bypassed direct review, or violated some specific procedural rule requiring a particular claim to be raised at a certain time, did we find a procedural default. We note that one circuit has held that the cumulative effect of a trilogy of recent Supreme Court decisions involving 28 U.S.C. § 2254 11 was to overrule Kaufman and imposed a general requirement that federal defendants raise their claims on direct review or forfeit them. See Campino v. United States, 968 F.2d 187, 190 (2d Cir.1992). While it is far from obvious that the recent Supreme Court decisions— which all involve state court proceedings and all deal with quite different issues from the question resolved by Kaufman — in fact overrule Kaufman , we need not face this question here. In 1989 at least, Kaufman was the law of this circuit.

The government has not identified any specific procedural rule which required a defendant to raise in a petition for certiorari or a motion to recall the mandate a claim that a magistrate impermissibly conducted voir dire, and we are not able to discover any such rule. Nor are we able to discover any rule which required this claim to be raised at all on direct review. Thus, under Kaufman , the petitioners did not commit any procedural default so long as (1) their claim is constitutionally based; and (2) their failure to raise the claim on direct review did not constitute a deliberate bypass. We conclude that the petitioners did not default on their claims. 12

*482 We have little difficulty in determining that the petitioners’ claims are constitutionally based. As we explained in France , the decision in Gomez should be treated as a constitutional decision for the purposes of procedural doctrines involving the assertion of constitutional claims: “The Supreme Court, although its decision was, in the end, one of statutory construction, made clear that its holding was compelled by the notion that any other result might well run afoul of the Constitution by authorizing the deprivation of one of the ‘basic rights’ of a criminal defendant.” France, 886 F.2d at 226 (citing Gomez, 490 U.S. at 863, 871-76 , 109 S.Ct. at 2241, 2246-48 ). Even the Supreme Court’s subsequent opinion in Peretz , which held that a defendant’s consent to a magistrate’s conduct of voir dire cures any Gomez problem, made clear Gomez’s constitutional underpinnings. In a footnote explaining why the Gomez Court found the constitutional question to be a substantial one, the Court in Peretz quoted extensively from Commodity Futures Trading Comm’n v. Schor, 478 U.S. 833, 848 , 106 S.Ct. 3245, 3255 , 92 L.Ed.2d 675 (1986), which had “emphasized the importance of the personal right to an Article III adjudicator.” Peretz, 501 U.S. at 930 n. 6, 111 S.Ct. at 2665 n. 6. 13

Of course, we do not mean to suggest that the Supreme Court would necessarily have decided the constitutional issue in Gomez’s favor had it been unable to construe the statute to avoid the question. However, we believe that when a petitioner raises a substantial constitutional claim (as the petitioners here have surely done), he should not lose his right to collateral review simply because the Supreme Court has mooted the constitutional aspect of the claim by resting on a nonconstitutional ground which favors him. We also believe that it would be inappropriate to render a wholly advisory opinion on the constitutional issue when the Supreme Court has for sound and principled reasons avoided the question. Rather, as in France , in which we held that the retroactivity rules governing constitutional claims apply to the Gomez holding, we conclude that a petitioner raising a Gomez claim is entitled to the benefit of the procedural doctrines which govern the assertion of constitutional claims in § 2255 proceedings.

Moreover, even if there is no constitutional right to have an Article III judge rather than a magistrate conduct voir dire, a defendant has a basic right “to have all critical stages of a criminal trial conducted by a person with jurisdiction to preside.” Gomez, 490 U.S. at 877 , 109 S.Ct. at 2248 . This right, rooted in due process, is itself constitutional in status, as the Gomez Court made clear by analogizing it to such “basic fair trial rights” as “a defendant’s ‘right to an impartial adjudicator, be it judge or jury.’ ” Id. (quoting Gray v. Mississippi, 481 U.S. 648, 668 , 107 S.Ct. 2045, 2056 , 95 L.Ed.2d 622 (1987)). 14 We join our fellow circuits which have adopted this reading of Gomez and held that the right to have all stages of a criminal trial conducted by a person with jurisdiction to preside is a constitutional right. See United States v. Chantal, 902 F.2d 1018 , 1021 n. 4 (1st Cir.1990); Matter of Hipp, Inc., 895 F.2d 1503, 1521 (5th Cir.1990); see also United States v. Baron, 721 F.Supp. 259, 261-62 *483 (D.Hawaii 1989) (holding that a violation of this right “undermin[es] the fundamental fairness of a felony trial”). 15 At the very least, the petitioners here are asserting the constitutional right to have voir dire conducted by an officer with jurisdiction.

We also cannot conclude that English, Taño, and Davis deliberately bypassed direct review. In order to find a deliberate bypass, we must find that the petitioners themselves — and not merely their counsel — made a knowing, intelligent, and voluntary decision to forego presenting the claims on direct review. As the Supreme Court explained when it set forth the deliberate bypass standard in Fay v. Noia, 372 U.S. 391 , 83 S.Ct. 822 , 9 L.Ed.2d 837 (1963), we may hold that a defendant deliberately bypassed direct review only if the bypass satisfies “[t]he classic definition of waiver enunciated in Johnson v. Zerbst, [ 304 U.S. 458, 464 , 58 S.Ct. 1019, 1023 , 82 L.Ed. 1461 (1938) ] — ‘an intentional relinquishment or abandonment of a known right or privilege.’” Id. at 439, 83 S.Ct. at 849 . We will only find a deliberate bypass where “a habeas applicant, after consultation with competent counsel or otherwise, understandably and knowingly forewent the privilege” of pursuing his claims on direct review. Id. When applying this standard, “[a] choice made by counsel not participated in by the petitioner does not automatically bar relief.” Id. Rather, we will find a deliberate bypass only if the failure to pursue appellate remedies results from “the considered choice of the petitioner.” Id.

The government has not satisfied its burden of showing a deliberate bypass here. Although it is clear that the petitioners’ attorneys made a conscious decision to pursue the Gomez claims in § 2255 proceedings rather than on direct review, 16 the record is devoid of any evidence that the petitioners themselves had any input into this decision. A decision of this character — whether to pursue a particular claim in the Supreme Court on a petition for certiorari, in this court on a motion to recall the mandate, or in a district court on a § 2255 motion — is one that is typically made by the lawyer, not the client. Nothing in the record suggests that the typical practice was not followed in this case.

Even if the petitioners were consulted, we would be quite surprised if they had any understanding of the relevant differences between pursuing the claim on direct appeal and filing a § 2255 motion. The choice of forum in this case appears to have resulted from purely legal considerations. The attorneys for English and Tano contend that they failed to pursue the claim in their petition for certiorari because they believed that Supreme Court rules prevented them from raising the issue in that court for the first time, and that they failed to move this court to recall the mandate because they believed that the claim was a jurisdictional one that could be addressed in a § 2255 motion in the first instance. 17 Although the petitioners’ attorneys may have erred in this assessment (a conclusion on which we express no view), the government must make a far stronger showing before we would conclude that the petitioners themselves had sufficient knowledge and understanding of these issues to satisfy the Johnson v. Zerbst waiver standard.

Indeed, our conclusion that the petitioners did not make a knowing, intelligent, and voluntary decision to forego direct appeal would only be strengthened if we were to decide *484 that their attorneys erred in choosing to pursue the claim in the district court. Defendants ought not to be expected to understand the complex web of procedural rules that now regulates the time and place in which a party may raise a meritorious claim. They must rely on their attorneys to advise them accurately regarding the risks and consequences of choosing to pursue the claim in one forum rather than another. Where an attorney erroneously advises a defendant that he is not required to raise a claim on direct appeal, we cannot say that the defendant deliberately bypassed direct review.

We conclude that English, Taño, and Davis did not deliberately bypass the opportunities to raise their Gomez claims on direct review. We also conclude that there was no specific procedural rule which required them to assert the claim in petitions for certiorari or motions to recall the mandate. Accordingly, they did not procedurally default on their claims. Thus, the cause and prejudice analysis is inapplicable here. The district court was required to reach the merits of English, Taño, and Davis’s claims. Had it done so, it would have been obliged to rule in the petitioners’ favor.

Conclusion

The judgment of the district court in English v. United States, No. 91-16442, and Tano v. United States, No. 91-16500, is REVERSED. The judgment of the district court in United States v. Davis, No. 92-15368, is AFFIRMED.

. English and Tano claim that they did not file such a motion because (1) the language of this court’s decision in France precluded it; (2) this court was closed to all but emergency motions following the Loma Prieta earthquake in October of 1989; and (3) the government took the position that the Gomez issue could not be raised for the first time in this court on appeal. The sec *476 ond ground, at least, is frivolous if not sanctiona-ble.

. As noted in note 1, supra, the third ground is clearly erroneous.

. Nor does it argue that any principle of nonre-troactivity prevents us from reaching the merits in this case. Because Gomez was decided before the petitioners' convictions were final, they are entitled to the benefit of that decision. See United States v. France, 886 F.2d 223, 227 (9th Cir.1989).

. The Frady court's use of the term "double procedural default,” apparently to refer to Fra-dy’s failure to raise the claim on appeal after he did not assert it before the jury retired, does not change this analysis. The Supreme Court’s decision to find a procedural default rested on its conclusion that Frady had violated Rule 30 at trial. Because Frady did not correct his violation of Rule 30 on appeal by raising the issue as plain error under Rule 52(b), the Court found a second procedural default. However, Frady's violation of a procedural rule at trial was essential to the Court’s conclusion that he had violated Rule 52(b) on appeal. See Frady, 456 U.S. at 163 , 102 S.Ct. at 1592 . The Court did not suggest that it would ever find a single procedural default where the defendant simply failed to raise a claim on appeal, absent some violation of a procedural rule in the district court. Any such suggestion would have been inconsistent with Davis, on which the Frady Court relied. See infra.

. Similarly, because the petitioners' trials occurred before Gomez corrected this circuit's erroneous rule that a magistrate could preside over jury selection in a felony trial, their failure to object cannot be taken as consent to the magistrate's conduct of voir dire. See United States v. Gamble, 943 F.2d 1030, 1031 (9th Cir.1991) (per curiam).

. Although the sentence quoted from Schaflander did not specify under what standard a petitioner may bring a constitutional claim on a § 2255 petition (cause and prejudice or deliberate by *480 pass), it is clear that the Schaflander court was endorsing the Kaufman rule. Kaufman sets forth a general rule that constitutional claims may be raised on collateral proceedings even if the defendant failed to raise them on appeal. This rule is subject to an exception for cases where the government shows that the defendant committed a deliberate bypass. In cases in which the cause and prejudice standard applies, by contrast, the general rule is that constitutional claims may not be raised in collateral proceedings if they were defaulted on direct appeal. This rule is subject to an exception if the petitioner shows cause and prejudice. Our language in Schaflander is far more consistent with the Kaufman rule than the cause and prejudice rule. Moreover, the two cases cited by the Schaflander court in support of this statement both rely on Kaufman. See Davis, 417 U.S. at 345 n. 15, 94 S.Ct. at 2304 -05 n. 15 (citing Kaufman, 394 U.S. at 223 , 89 S.Ct. at 1072 ); Marshall, 576 F.2d at 161 (citing Kaufman).

. As we noted in Chambers , "[o]ur analysis has been consistent with the approach the Second Circuit took in Corsentino.... As Schaflander and O'Mara make clear, we have not held that the failure to raise a claim, absent a rule requiring it to be raised or waived, constitutes a procedural default.” Id. at 945.

. Like Frady, Abatino (and Dunham) included dictum stating that the petitioner had committed a second procedural default by failing to correct his violation of Rule 30 on direct appeal by raising the claim as plain error. Like the identical dictum in Frady , this statement in Abatino (and Dunham) does not suggest that even a single procedural default occurs where, as here, no rule required the defendant to raise the issue at trial, and the defendant later failed to assert it on direct review. Indeed, no case in this circuit has ever held that the mere failure to raise a claim on direct review constitutes a procedural default in that situation.

. A footnote in Dunham stated that the petitioner had defaulted a second claim — that there was an error in the trial transcript — by failing to raise it on appeal, even though it obviously could not have been raised at trial. However, the failure to assert this error on appeal constituted a direct violation of Fed.R.App.P. 10(e), which states that "questions as to the form and content of the record shall be presented to the court of appeals.” Thus, Dunham falls squarely within Fra-dy's rule that the failure to comply with an applicable procedural requirement constitutes a default.

. A case decided after the purported defaults here, United States v. Johnson, 988 F.2d 941 (9th Cir.1993), also stated that a defendant who failed to raise a claim on direct appeal must show cause and prejudice in order to assert that claim in a § 2255 proceeding. See Id. at 945. Although the petitioner in Johnson asserted a claim which no specific procedural rule required him to raise on direct review, Johnson does not support a conclusion that English, Taño, and Davis committed a procedural default, for two reasons. First, and most important, Johnson was decided in 1993, four years after the alleged default in this case. If it did in fact impose the requirement that all claims be brought on direct appeal or be waived, this requirement could not be applied retroactively to forfeit English, Taño, and Davis's claims. Second, our holding in Johnson did not rest on procedural default at all. Instead, we denied Johnson's claim because it constituted a "merely conclusoty statement,” which we have held to be " 'not enough to require a hearing.' " Id. (quoting United States v. Hearst, 638 F.2d 1190, 1194 (9th Cir.1980), ce rt. denied, 451 U.S. 938 , 101 S.Ct. 2018 , 68 L.Ed.2d 325 (1981)).

. See Keeney v. Tamayo-Reyes, - U.S. -, 112 S.Ct. 1715 , 118 L.Ed.2d 318 (1992) (applying the cause and prejudice test to the failure to develop material facts in state court proceedings); Coleman v. Thompson, 501 U.S. 722 , 111 S.Ct. 2546 , 115 L.Ed.2d 640 (1991) (applying the cause and prejudice test to all violations of independent and adequate state procedural rules); McCleskey v. Zant, 499 U.S. 467, 495-96 , 111 S.Ct. 1454, 1471 , 113 L.Ed.2d 517 (1991) (applying the cause and prejudice test to new-claim subsequent petition cases).

. The government asserts that English committed a default by "ignor[ing] the district court's instruction to file a motion to recall the mandate in this Court.” However, English received no such instruction. The district court merely held English's motion in abeyance until his direct appeal was final. It did not direct him to file any motion in any court. We note that the government does not make any similar contention with respect to Tano, although it could certainly have done so with more factual accuracy. In any event, given all of the circumstances present here, we seriously doubt that we would conclude that the district court's order in Tano's case constituted the type of procedural rule contem *482 plated by Ford v. Georgia, 498 U.S. 411 , 111 S.Ct. 850 , 112 L.Ed.2d 935 (1991).

. The Peretz Court quoted the following passage from Schor :

Peretz, 501 U.S. at 930 n. 6, 111 S.Ct. at 2665-66 n. 6 (quoting Schor, 478 U.S. at 848 , 106 S.Ct. at 3255 ) (citations omitted).

. Of course, the right to an impartial adjudicator is a constitutional right. The Gray Court made this clear by referring to “the constitutional right to an impartial jury” and by citing Turney v. Ohio, 273 U.S. 510 , 47 S.Ct. 437 , 71 L.Ed. 749 (1927) (holding that there is a constitutional right to an impartial judge), both on the same page to which the Gomez Court cited. See Gray, 481 U.S. at 668 , 107 S.Ct. at 2056-57 .

. At least one circuit has suggested that Gomez announced a constitutional right to have all critical stages of a felony trial conducted by a person with jurisdiction to preside over the entire proceeding. See United States v. Vanwort, 887 F.2d 375, 378 (2d Cir.1989). We need not go so far here, however.

. In English and Tano’s cases, the district judge made the following finding:

United States v. English, 777 F.Supp. 791, 793 (D.Hawaii 1991). Because Davis was represented by the same attorney as English, the second part of the finding would appear to apply to his case as well.

.As noted above, the district court explicitly found that the latter reason motivated the choice of forum in this case. See supra note 16.
