Certificate of Appealability: Strategy & Standards

By Melissa Grant

A Certificate of Appealability (COA) is required to appeal the denial of habeas corpus relief under 28 U.S.C. § 2253(c). Without a COA, the appellate court lacks jurisdiction to review the merits.

The Legal Standard

Under Slack v. McDaniel and Miller-El v. Cockrell, an applicant must demonstrate that reasonable jurists could debate whether:

1. The petition states a valid claim of denial of a constitutional right, OR
2. The district court was correct in its procedural ruling

This is a threshold inquiry — the applicant need not prove the merits, only that the issues deserve further examination.

When to Seek a COA

A COA may be requested from:

• The district court at the time of denial
• The circuit court if the district court denies the COA
• Both courts may be approached sequentially

Drafting Persuasive COA Applications

Focus on Debatability

• Frame issues as genuine constitutional questions
• Cite circuit splits or unsettled law
• Highlight factual disputes that warrant further review

Structure and Clarity

• Lead with the strongest issue
• Provide concise factual background
• Cite specific constitutional provisions at stake
• Distinguish unfavorable precedent rather than ignoring it

Common Mistakes to Avoid

• Rehashing trial arguments without constitutional framing
• Filing boilerplate applications without case-specific analysis
• Missing filing deadlines
• Failing to identify the specific constitutional right at issue

Strategic Considerations

• Request a COA from the district court first — some judges grant them liberally
• If denied, file promptly in the circuit court
• Consider whether the issue has broader implications that may interest the court
• Coordinate COA strategy with any pending § 2255 proceedings

Drafting persuasive COA applications is critical for preserving the right to further appellate review.
