What it's about

The Court refused to hear the case (denied review) and did not decide either question.

The petition asked whether courts must apply Batson's three-step jury-selection analysis in order and whether a substitute medical examiner may rely partly on an autopsy report by an examiner who did not testify.

Question presented

1. When a defendant raises a challenge during jury selection, under Batson v. Kentucky, 476 U.S. 79 (1986), is the trial court required to apply Batson’s three-step analysis sequentially? 2. Is the admission of a substitute medical examiner’s expert opinion, based in part on an autopsy report prepared by a non-testifying medical examiner, contrary to this Court’s decision in Smith v. Arizona, 602 U.S. 779 (2024)?
