Can exhausting peremptory challenges on biased jurors establish prejudice in Utah criminal appeals? State v. Meraz-Zamorano Explained

In State v. Meraz-Zamorano, the Utah Court of Appeals addressed a common appellate issue: whether a defendant suffers prejudice when forced to use all peremptory challenges on jurors who should have been excused for cause. The case provides important guidance on the prejudice standard for jury selection errors.

Background and Facts

Meraz-Zamorano was charged with multiple counts of sexual abuse involving two minor girls. During voir dire, he challenged several prospective jurors for cause, but all challenges were denied. Defense counsel used six peremptory challenges to remove these individuals, and the State used one peremptory challenge to remove the seventh. Importantly, none of the challenged individuals ultimately sat on the jury. During trial, improper statements arose when the mother mentioned a child’s suicide attempt and when a detective’s comment about Meraz-Zamorano being in jail was inadvertently played for the jury.

Key Legal Issues

The appeal raised three issues: (1) whether the trial court abused its discretion in denying for-cause challenges; (2) whether improper statements during trial warranted a mistrial; and (3) whether Children’s Justice Center interview recordings were properly admitted under Rule 15.5 of the Utah Rules of Criminal Procedure.

Court’s Analysis and Holding

The Court of Appeals assumed without deciding that some for-cause challenges may have been improperly denied but found no prejudice because none of the challenged individuals served on the jury. The court emphasized that “the loss of a peremptory challenge alone [is] not sufficient to prejudice a party”—defendants must show “that a member of the jury was partial or incompetent.” Regarding the mistrial motions, the court found the improper statements were not intentionally elicited, were made in passing, and were adequately addressed by curative instructions. The CJC interviews were properly admitted because defense counsel had extensively quoted from them to challenge the detective’s questioning techniques.

Practice Implications

This decision reinforces that Utah follows the majority rule requiring actual prejudice from jury selection errors. Simply exhausting peremptory challenges is insufficient—practitioners must identify specific bias or incompetence among seated jurors. For mistrial motions, courts will consider whether statements were intentionally elicited and whether curative instructions can remedy any prejudice. When challenging interview admissions, be aware that extensive use of transcripts in cross-examination may open the door for video admission.
