Jury Selection and Service in Utah

Jury selection and service in Utah govern how citizens are summoned, screened, and seated to decide civil and criminal cases in state courts. The process draws on both Utah statute and court rule, making it one of the more procedurally dense areas of trial practice. Understanding how jurors are selected, what exemptions apply, and how challenges operate clarifies why juries look the way they do by the time opening statements begin. This page covers the legal framework, step-by-step mechanics, common participant scenarios, and the boundaries of Utah jury law as distinct from federal jury practice.

Definition and Scope

Jury service in Utah is a constitutional obligation grounded in Article I, Section 10 of the Utah Constitution, which guarantees the right to a jury trial in criminal prosecutions, and Article I, Section 11, which preserves that right in civil matters. The operational rules are codified primarily in Utah Code Ann. §§ 78B-1-101 through 78B-1-158, which covers juror qualification, the master jury list, summoning procedures, and compensation.

Jury service applies to district courts and, in serious criminal matters, to the Utah Court of Appeals context where retrials are ordered. The Utah Rules of Civil Procedure (Rule 47) and Utah Rules of Criminal Procedure (Rule 17) establish the procedural mechanics of voir dire, juror challenges, and alternate juror seating within their respective case types.

Scope limitations: This page covers Utah state court jury processes only. Federal jury selection in the District of Utah operates under the Jury Selection and Service Act of 1968 (28 U.S.C. §§ 1861–1878) and the District of Utah's local rules — those procedures are not covered here. Utah justice courts do not use juries; that limitation is addressed in the Utah Justice Courts Scope and Limitations page. Tribal court proceedings are also outside this page's scope; for that framework, see Utah Tribal Courts and Sovereign Jurisdiction.

How It Works

The Utah jury selection process moves through five discrete phases:

1. Master Jury List Assembly. The Utah State Courts compile a master jury list by merging voter registration records and driver license/ID records from the Utah Driver License Division, as required by Utah Code Ann. § 78B-1-106. This combined source pool is refreshed annually and is designed to achieve a cross-section of the community.

2. Summons and Qualification. Random selection from the master list produces a panel of prospective jurors who receive a written summons. Under § 78B-1-105, qualified jurors must be: (a) U.S. citizens, (b) Utah residents, (c) at least 18 years of age, (d) able to communicate in English sufficiently to understand proceedings, and (e) free of certain felony convictions unless civil rights have been restored. Individuals who do not meet these criteria are excused by the court clerk at the qualification stage — before voir dire begins.

3. Voir Dire. This is the oral examination phase in which the judge and attorneys question the panel to identify bias or grounds for disqualification. In Utah district courts, judges often conduct the primary examination, with attorneys permitted to follow up (Utah R. Civ. P. 47(b)). Voir dire is conducted in open court and is part of the public record unless the court issues a specific protective order.

4. Challenges. Two distinct challenge types exist under Utah law:

5. Challenges for cause — unlimited in number, granted by the judge when a prospective juror demonstrates actual bias, a disqualifying relationship to a party, or inability to apply the law. Either party may raise these.

6. Peremptory challenges — limited in number and exercisable without stated reason, subject to constitutional limits. In civil cases, each side receives 3 peremptory challenges (Utah R. Civ. P. 47(e)). In criminal cases, the number scales with severity: 4 peremptory challenges in class A misdemeanor trials, and up to 10 per side in first-degree felony trials (Utah R. Crim. P. 17(n)). Peremptory challenges may not be used to exclude jurors on the basis of race or sex under Batson v. Kentucky, 476 U.S. 79 (1986), as applied in Utah courts.

7. Seating and Alternates. Standard Utah civil juries seat a minimum of 4 jurors (Utah R. Civ. P. 47(b)); criminal juries seat 12. Alternate jurors — up to 4 in lengthy trials — are seated in the same manner and replace any seated juror who becomes unable to continue.

Juror compensation in Utah is set at $18.50 per day for the first day and increases for extended service, per Utah Code Ann. § 78B-1-112. Employers are prohibited from penalizing employees for jury absence under § 78B-1-116.

Common Scenarios

Excusal vs. Deferral. A summoned juror who demonstrates undue hardship — such as a pre-scheduled surgery or sole-caregiver status — may request a deferral rather than a permanent excusal. Deferrals postpone service to a date within 6 months; permanent excusals require documented, ongoing incapacity. These are administrative determinations made by jury commissioners, not judges, in the first instance.

Grand Jury vs. Petit Jury. Utah empanels both types. A grand jury — comprising 12 to 23 citizens — determines whether probable cause supports a felony indictment, operating under Utah Code Ann. §§ 77-10a-1 et seq. and meeting in closed session. A petit jury (the trial jury described above) decides facts at open trial. The Utah Grand Jury and Indictment Process page covers grand jury mechanics separately.

Civil vs. Criminal Jury Standards. The contrast is significant: criminal verdicts in Utah require unanimity among all 12 jurors; civil verdicts require agreement by at least three-fourths of the jury panel, meaning 3 of 4 jurors on a minimum panel, or 9 of 12 on a standard panel (Utah R. Civ. P. 49). This distinction is foundational — see Civil vs. Criminal Law in Utah for the broader doctrinal difference.

Juror Misconduct. If a seated juror independently researches case facts, communicates with parties, or engages in prohibited deliberation conduct, a party may move for a mistrial or post-verdict challenge. The Utah Rules of Evidence and Rule 606(b) specifically restrict when juror testimony may be used to impeach a verdict.

Decision Boundaries

Several threshold questions govern whether and how jury service applies in a given Utah proceeding:

• Jury-trial right exists: Felony criminal cases and civil cases where the amount in controversy or subject matter triggers the constitutional right. The 7th Amendment analog in Utah civil practice is preserved through Utah R. Civ. P. 38; the right must be affirmatively demanded by timely written request.
• Jury-trial right waived or inapplicable: Small claims proceedings (no jury; see Utah Small Claims Court Procedures), bench trials by stipulation, and cases resolved by summary judgment or default.
• Exemptions from service: Active judges, law enforcement officers serving in an active capacity, and individuals with prior service within the preceding 24 months in certain counties may be
