The state appeals a conditional grant of a writ of habeas corpus to Eric Moore. Moore cross-appeals, asking us to vacate the writ and instruct the district court to conduct an evidentiary hearing. We vacate the writ and remand for further proceedings, which need not necessarily include the requested evidentiary hearing.
This court previously granted Moore permission to file a successive habeas petition under the Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”), 28 U.S.C. § 2254, because he had made a
prima facie
showing of entitlement to relief predicated on
Atkins v. Virginia,
The district court did neither, but instead granted Moore a stay of execution and agreed with our assessment that Moore could file his successive habeas petition because it satisfied the requirements of 28 U.S.C. § 2244(b)(2)(A). 1 Moore— *846 seeking to develop the record in anticipation of a hearing on the merits of his petition — moved for appointment of a psychologist trained in the field of mental retardation, and for a social history investigation. The district court denied those requests as premature.
Instead of holding the hearing that Moore sought, the court opted to fault the state courts for a perceived misapplication of their own laws in acting on Moore’s state habeas petition. To remedy the state’s “error,” the court granted the writ and conditionally ordered Moore released. The court provided that its order would not take effect if the state courts either (a) reopened Moore’s state habeas petition and conducted a fact-finding hearing to determine whether his execution would violate Atkins or (b) commuted the sentence to life imprisonment.
On appeal, neither party defends the district court’s decision. It is axiomatic that “infirmities in state habeas proceedings do not constitute grounds for federal habeas relief.”
Duff-Smith v. Collins,
As a result, the district court had no basis for its conclusion that Moore was entitled to habeas relief on a mere showing that the Texas courts had misapplied their own procedural rules to his state habeas petition. Rather, the district court’s habe-as jurisdiction extends only to claims that the petitioner “is in custody in violation of the Constitution or laws or treaties of the United States,” see 28 U.S.C. § 2254(a), and it is only on a finding of such a violation that the court may grant habeas relief. The district court did not find a violation of federal law, so we vacate the writ. 3
In his cross-appeal, Moore raises two issues that are premature at this stage of the litigation. He argues that he is entitled to an evidentiary hearing on his claim of mental retardation and that his petition is not procedurally defaulted. The district court has not addressed these questions, so we decline to consider them on appeal.
See Floors Unlimited, Inc. v. Fieldcrest Cannon, Inc.,
On remand, the court must consider whether Moore is entitled to an evidentia-ry hearing under 28 U.S.C. § 2254(e)(2)(A) and (B). Regardless of whether it holds such a hearing, the court must determine whether Moore’s claim is procedurally defaulted' — an issue that it expressly reserved. If it decides that there is no default, the court must determine whether Moore is entitled to relief on the merits of his Atkins claim, and if so, the court should fashion an appropriate remedy.
*847 We VACATE the writ and REMAND for farther proceedings not inconsistent with this opinion.
Notes
. The district court found only that Moore's petition "appears” to satisfy the requirements of 28 U.S.C. § 2244(b)(2)(A) and that "it certainly does not conclusively demonstrate that it does not meet the three elements” of that section. That is insufficient. AEDPA expressly and unambiguously provides that the district court "shall dismiss” the petition "unless the applicant shows that the claim satisfies the requirements of this section.” 28 U.S.C. § 2244(b)(4). The mere appearance of compliance is an insufficient basis to authorize the filing of a successive habeas petition.
We recognize, however, that this error flows naturally from a literal interpretation of language from
In re Morris,
The correct standard is still the one in the statute: The applicant bears the burden of demonstrating that the petition does in fact comply with the statute, and the district court shall dismiss the petition unless that showing is made.
See
28 U.S.C. § 2244;
Brown v. Lensing,
*846
We do not use this reason to vacate the writ, however, because the state does not make this argument on appeal.
See United States v. Thibodeaux,
.
See also Henderson v. Cockrell,
. We are not insensitive to the district court's statement, made in the course of denying a motion to reconsider, that the parties failed adequately to brief this issue despite specific instructions to do so. Nevertheless, the issue is jurisdictional, and the court was required to consider it
sua sponte
if necessary.
