Must trial courts investigate all prospective jurors who indicate potential bias? State v. King Explained

The Utah Court of Appeals addressed a critical issue in jury selection in State v. King, where the trial court’s incomplete investigation of potentially biased jurors led to reversal of a sexual abuse conviction.

Background and Facts

King was charged with sexual abuse of a child. During voir dire, eleven prospective jurors—over one-third of the pool—indicated that they, family members, or friends had been victims of abuse or would have difficulty being fair and impartial. The trial court questioned nine of these jurors individually, and none served on the jury. However, two jurors (F and I) who had indicated connections to abuse were never questioned individually, yet both served on the jury that convicted King.

Key Legal Issues

The court examined whether the trial court fulfilled its obligation to investigate potential juror bias and whether the failure to question all potentially biased jurors violated King’s right to an impartial jury under the Utah and U.S. Constitutions.

Court’s Analysis and Holding

The Court of Appeals held that when prospective jurors’ responses “facially question their impartiality,” the trial court must investigate further. The court emphasized that juror impartiality is “a mental attitude of appropriate indifference” and that adequate voir dire is necessary to determine each juror’s mental attitudes. The court noted that simply asking jurors if they can be impartial is insufficient, as many jurors may not understand what impartiality requires or may lack the insight to recognize their own bias.

Significantly, the court rejected the State’s argument that challenges must be made before the trial court’s investigative duty is triggered. The court emphasized that trial courts must “detect and investigate the potential for partiality” independently of counsel’s actions.

Practice Implications

This decision reinforces that trial courts must thoroughly probe all prospective jurors who indicate any potential bias. The court’s failure to question even two out of eleven potentially biased jurors was sufficient to require reversal. Practitioners should ensure complete investigation during voir dire and be prepared to object if courts fail to adequately probe all potentially biased jurors. The decision also clarifies that the trial court’s investigative duty is independent of whether counsel raises challenges.
