Whether a court of appeals may deny a certificate of appealability by resolving the merits of a state prisoner's habeas claim under AEDPA rather than conducting the required threshold inquiry.
Holding
No. A COA inquiry asks whether reasonable jurists could debate the district court's resolution of the constitutional claim, not whether the petitioner has already proved entitlement to habeas relief.
Reasoning
A COA is a jurisdictional prerequisite to an appeal from the denial of federal habeas relief. Under 28 U.S.C. § 2253(c)(2), the applicant must make a substantial showing of the denial of a constitutional right. That standard is met when reasonable jurists could disagree with the district court's resolution of the claim or could conclude that the issue deserves encouragement to proceed further.
The COA decision requires an overview of the claim and a general assessment of its merits, including the district court's application of AEDPA. But it does not permit a court of appeals to decide the appeal's ultimate merits first and then deny a COA because the petitioner would lose. Doing so effectively decides an appeal without jurisdiction.
The COA standard is more demanding than merely showing good faith or a nonfrivolous claim, and issuance is not automatic. But the prisoner need not show that the appeal will succeed. A claim may be sufficiently debatable to warrant a COA even if, after full briefing and review, every reasonable jurist ultimately agrees that habeas relief should be denied.
