Peter Mercadel appeals the district court’s denial of habeas relief on the merits of his claim that he was deprived of the effective assistance of counsel on direct appeal because his attorney filed only an errors-patent brief on his behalf. We conclude that Mercadel has failed to fairly present this claim to the Louisiana state courts, and therefore that he has failed to exhaust his state court remedies. We therefore vacate the district court’s judgment and remand with instructions to dismiss Mercadel’s habeas application without prejudice to allow him to exhaust his remedies in Louisiana state court.
I. FACTUAL AND PROCEDURAL HISTORY
In 1976, Peter Mercadel was convicted of second-degree murder in Louisiana state court and sentenced tо life imprisonment. In 1977, Mercadel filed an application for a writ of habeas corpus in Louisiana criminal district court, arguing that his attorney’s failure to file a timely appellate brief on his behalf violated his rights under the Fifth, Sixth and Fourteenth Amendments. The Louisiana Supreme Court apparently construed his habeas corpus application as a writ of mandamus *273 and granted Mercadel an out-of-time appeal. On June 23, 1980, Mercadel’s appellate counsel, Dwight Doskey, filed an appellate brief with the Louisiana Supreme Court on behalf of Mercadel. The appellate brief was, including the cover page, the table of contents, and the certification, only four pages long. After setting forth the statement of the case, the brief addressed only one issue:
ASSIGNMENT OF ISSUE No. 1
Defendant respectfully requests the Court to review the record for error patent on the face of the record. La. Constitution of 1974, Article 1, Section 19, State v. Martin,329 So.2d 688 (La.1976). In accord with such a review, the defendant asks the Court to reverse his conviction and sentence.
On October 15, 1980, the Louisiana Supreme Court affirmed Mercadel’s conviction without a formal opinion.
See State v. Mercadel,
On April 6, 1983, Mеrcadel filed another habeas petition in state court, alleging that the evidence was insufficient to support his conviction. After the Louisiana Supreme Court granted Mercadel’s motion for a writ of mandamus and ordered the trial court to rule on the habeas petition, the state trial court denied Mercadel collateral relief in a one-page order. In totаl, the trial court ruled:
In his writ, petitioner contends that the evidence adduced at trial was insufficient to sustain a conviction.
This case was argued before the Supreme Court of Louisiana who affirmed said conviction on October 15, 1980 in case number 66,998.
Accordingly, the writ is denied.
In June 1994, Mercadel filed another application for post-conviction relief, this time in the Louisiana Supreme Court. 1 In this application, Mercadel raised the issue before us today, i.e., whether he was denied the effective assistance of counsel on direct appeal. Two years later, on June 28, 1996, the Louisiana Supreme Court rejected this claim in a one-word order in which the court stated that his application was “[djenied.”
On May 23, 1997, Mercadel, proceeding pro se, filed an application for habeas relief in the United States District Cоurt for the Eastern District of Louisiana. In his federal habeas application, he argued that he was constructively denied his Sixth Amendment right to the effective assistance of counsel on direct appeal. The district court denied the application; after noting that the Anti-Terrorism and Effective Death Penalty Act of 1996 (AEDPA) applied, the court ruled that the application was untimely under 28 U.S.C. § 2244(d), and, alternatively, that the Louisiana Supreme Court’s resolution of the Sixth Amendment issue did not constitute an unreasonable application of clearly established federal law as determined by the Supreme Court under 28 U.S.C. § 2254(d)(1). A panel of this court granted Mercadel a certificate of appealability (COA) to appeal the issue of “whether Mercadel was constructivеly denied counsel when his appellate attorney filed only an ‘errors-patent’ brief on his behalf.” 2 This timely appeal followed.
*274 II. DISCUSSION
A. Adjudication on the Merits
Mercadel filed his habeas application after April 24, 1996, and it is therefore subject to AEDPA.
See Lindh v. Murphy,
with respect to any claim that was adjudicated on the merits in State court proceedings unless the adjudication of the claim—
(1) resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States.
28 U.S.C. § 2254(d). The first question we must consider is whether the Louisiana Supreme Court’s one-word denial of Mer-cadel’s June 1994 motion for post-conviction relief is an adjudication on the merits to which we must defer under AEDPA.
In this circuit, the question of whether a state court’s decision is аn adjudication on the merits turns on “the court’s disposition of the case—whether substantive or procedural.”
Green v. Johnson,
(1) what the state courts have done in similar cases; (2) whether the history of the case suggests that the state court was aware of any ground for not adjudicating the case on the merits; and (3) whether the state courts’ opinions suggest reliance upon procedural grounds rather than a determination on the merits.
Consideration of these factors leads us to conclude that thе Louisiana Supreme Court’s denial of relief on Mercadel was on procedural grounds, and therefore not on the merits. The third Green factor does not come into play in this case; the Louisiana Supreme Court’s one-word rejection of Mercadel’s petition is silent as to the reason for the denial of relief. However, our thorough review of the record convinces us that the first and second Green factors weigh heavily in favor of our treating the state court denial as a procedural decision. Mercadel addressed his July 1994 habeas application to the Louisiana Supreme Court, rather than “the district court for the parish in which the petitioner was convicted.” 3 La.Code Crim. PROC. Ann. art. 926(A) (“An application for post conviction relief shall be by written petition addressed to the district court for the parish in which the petitioner was convicted.”). Obviously, the Louisiana Supreme Court lacks original jurisdiction to hear the merits of state prisoners’ habeas petitions; its normal role is, of course, to review the decisions made by Louisiana state courts that are granted original jurisdiction to hear such claims. Thus, the history of the case suggests that the Louisiana Supreme Court was aware of a ground for not adjudicating the case on the merits; article 926(E) of the Louisiana Code of Criminal Procedure provides that “[ijnexcusable *275 failure of the petitioner to comply” with the filing requirements “may be a basis for dismissal of his application.”
Further, the first
Green
factor, “what the state courts have done in similar cases,”
Green,
In sum, we conclude that the AEDPA deference scheme outlined in 28 U.S.C. § 2254(d) does not apply to Mercadel’s application. The obvious procedural defect in Mercadel’s filing of his petition in the Louisiana Supreme Court instead of the district court, coupled with the Louisiana Supreme Court’s consistent practice of denying such improperly-filed petitions without considering the merits of the underlying claim, dictates this result.
B. Exhaustion of State Cotwi Remedies
We may not proceed directly to a de novo review of Mercadel’s Sixth Amendment claim, however, because it appears that the fact that Mercadel improperly filed his habeas petition including that claim with the Louisiana Supreme Court leads inexorably to the conclusion that he has failed to exhaust his state court remedies with respect to that claim.
Applicants seeking habeas relief under § 2254 are required to exhaust all claims in state court prior to requesting federal collateral relief.
See Fisher,
Respondents did not make this argument before the district court or on appeal; they focused solely (assuming that § 2254(d) would apply to Mercadel’s application) on whether the Louisiana Supreme Court’s denial of relief on Mercadel’s claim was “an unreasonable application of[ ] *276 clearly established Federal law, as determined by the Supreme Court.” 28 U.S.C. § 2254(d)(1). The state’s implicit waiver of the exhaustion issue, however, is not determinative. Under AEDPA, “[a] State shall not be deemed to have waived the exhaustion requirement or be estopped from reliance upon the requirеment unless the State, through counsel, expressly waives the requirement.” Id. § 2254(b)(3) (emphasis added). There is no evidence of such an explicit waiver in this case.
Mercadel’s failure to exhaust notwithstanding, this court could reach the merits of his Sixth Amendment claim if we were convinced that it lacked merit.
See id.
§ 2254(b)(2) (“An application for a writ of habeas corpus may be denied on the merits, notwithstanding the failure of the applicant to еxhaust the remedies available in the courts of the State.”);
Nobles v. Johnson,
Although AEDPA makes clear that a federal court can deny relief on unexhaust-ed claims, two of our recent cases suggest that the converse is not also true and that federal courts lack the power to
grant relief
on unexhausted claims.
See Alexander v. Johnson,
Although AEDPA authorizes a district court to deny relief on an unexhausted claim, it does not authorize a district court to grant relief on an unexhausted claim unless the State, through counsel, expressly waives the requirement. The State has not done so in this case. Aсcordingly, the district court lacked the authority to grant relief on the state statutory ground.
The general rule enforced by
Alexander
and
Jones
comports with the policy concerns underlying the exhaustion doctrine. The “exhaustion requirement is grounded in principles of comity; in a federal system, the States should have the first opportunity to address and correct alleged violations of state prisoner’s [sic] federal rights.”
Coleman v. Thompson,
Furthermore, we are mindful that “there is a strong presumption in favor of requiring the prisoner to pursue his available state remedies.”
Granberry,
III. CONCLUSION
For the foregoing reasons, we VACATE the judgment and this case is REMANDED to the district court with instructions to dismiss without prejudice.
Notes
. It also appears from the record that at some point between 1983 and 1991, Mercadel filed a “blanket” application for post-conviction relief and a motiоn for an extension of time within which to file a more specific application for collateral relief. Mercadel appealed the trial court’s denial of these motions to the Louisiana Supreme Court, which affirmed the trial court's dispositions on September 18, 1992.
. In our order granting Mercadel a COA, we noted that because the district court did not toll the applicable one-year statute of limitation for the time during which Mercadel had a properly filed slate habeas petition pending, the court incorrectly ruled that Mercadel's application was time-barred.
See Fields v. Johnson,
. In his habeas petition, Mercadel cites Louisiana Supreme Court Rule 27 and Louisiana Constitution Article 1, Sections 19 and 21 in support of his assertion that the Louisiana Supreme Court has original jurisdiction over his petition. However, none of these provisions grant the Louisiana Supreme Court the power to entertain a state prisoner's habeas petition in the first instance. See La. Sup.Ct. Rule 27 (approving a Uniform Application for Post-Conviction Relief for use in habeas petitions); La. Const, art. 1, § 19 ("No person shall be subjected to imprisonment or forfeiture of rights or property without the right of judicial review...."); La. Const, art. 1, § 21 ("The writ of habeas corpus shall not be suspended.”).
. We do not hold that Mercadel would necessarily be enLitled to relief; his case is arguably distinguishаble from
Lofton
and
Lombard
in that Mercadel does not identify any nonfrivo-lous issues that could have been raised in his direct appeal. In addition, Mercadel's conviction became final in 1980, and relief might be barred under the anti-retroactivity doctrine announced in
