What it's about

He also challenges the Fifth Circuit’s use of an Arizona method to assess whether stun-belt evidence harmed his defense under Texas’s capital-sentencing system.

The dispute concerns Harris’s challenge to his Texas death sentence based on his trial lawyers’ conduct and the use of stun-belt evidence.

Question presented

1. Whether Strickland requires a habeas court to identify and apply the prevailing professional norms in order to determine whether trial counsel’s performance at trial was constitutionally deficient. 2. Whether a habeas court may defer to trial counsel’s post-hoc explanation for their performance at trial in determining whether their conduct was constitutionally deficient. 3. Whether the Fifth Circuit erred by applying the Arizona weighing framework described in Thornell v. Jones, 602 U.S. 154 (2024), in determining whether counsel’s introduction of stun-belt evidence was prejudicial under Strickland instead of Texas’s different non-weighing capital scheme.
