Whether Jackson established that trial counsel rendered ineffective assistance by failing to challenge or strike Supinski after Supinski expressed possible partiality.
Holding
No. Because the direct-appeal record did not reveal counsel's reasons for leaving Supinski on the panel, Jackson failed to overcome Strickland's strong presumption that counsel acted pursuant to reasonable professional judgment.
Reasoning
The governing standard was Strickland v. Washington, which Texas had adopted in Hernandez v. State. Under Strickland, the defendant bears the burden to prove both deficient performance and prejudice—a reasonable probability that, absent counsel's errors, the result would have been different. Review also begins with a strong presumption that counsel's conduct fell within the broad range of reasonable professional assistance and may have reflected sound trial strategy.
The record was silent about why counsel did not challenge Supinski for cause or use a peremptory strike against him. Without evidence explaining counsel's decision, an appellate court could not properly conclude that the decision was deficient rather than strategic. Finding deficiency from that silence would itself require speculation.
Delrio v. State controlled. There, counsel did not remove a former narcotics officer who knew the defendant and said he could not be impartial. The Court held that a silent record did not rebut Strickland's presumption of reasonable strategy. Although Delrio discussed possible tactical explanations for counsel's choice, those examples were not essential to its holding; the decisive point was the absence of a record showing deficient performance.
