Updated Nov 11, 2026

In brief

Where it stands
Petition Pending

Awaiting an order on the petition

No decision timeline until the Court agrees to hear the case.

What it’s about
Scott Drake Clabourne filed a petition asking the Supreme Court to review whether Arizona wrongly barred his claim that his sentencing lawyer was ineffective, even though he says the harm became clear too late to file earlier.
What's at stake
For Clabourne, the unresolved question is whether his claims about ineffective legal help and Arizona’s filing rules can be reviewed in federal court.

Summary: written with AI from the case record.

What it's about

He also challenges Arizona’s use of filing rules to block federal review and argues that the allegedly deficient work of his appointed post-trial lawyers denied him equal protection.

Clabourne argues that the harm from his sentencing lawyer’s work became clear too late for an earlier post-conviction filing; he also says his appointed review lawyers provided deficient help.

Clabourne’s petition challenges Arizona’s rules for successive post-conviction claims raised while related issues were being litigated in federal court.

Question presented

1. Whether Arizona has ignored the Strickland prejudice prong in defaulting Mr. Clabourne’s sentencing IAC claim by requiring counsel to have filed a PCR petition before the prejudice was evident, during the pendency of Martinez litigation and in the face of a previous dismissal of PCR litigation with prejudice in the trial court. 2. Whether Arizona’s inconsistent application of its procedural default rules to successive PCR claims due to their simultaneous litigation in federal courts will render this procedural default inadequate to bar federal habeas review. 3. Whether Arizona’s creation of a non-discretionary right of review of IAC claims followed by Arizona’s appointment of inexperienced PCR counsel who provided concededly deficient representation was arbitrary and denied Mr. Clabourne Fourteenth Amendment Equal Protection under Douglas v. California.

What happens next

The Supreme Court must decide whether to hear the case. No argument or decision date is set.
