What constitutes substantial controversy for separate peremptory challenges in Utah? Carrier v. Pro-Tech Restoration Explained

The Utah Supreme Court’s decision in Carrier v. Pro-Tech Restoration provides crucial guidance on when trial courts may allocate separate peremptory challenges to co-parties under Utah Rule of Civil Procedure 47(c).

Background and Facts

Following a car accident at an intersection missing a stop sign, plaintiff Carrier sued driver Smith, his employer Pro-Tech Restoration, and Pleasant Grove City. Smith was driving a Pro-Tech van when he collided with Carrier at the intersection. Initially represented by the same attorney, Smith later obtained separate counsel after disputes arose with Pro-Tech over whether the company instructed him to provide false accident information. Despite separate representation and this internal conflict, all defendants maintained the shared defense that Carrier was more negligent than they were.

Key Legal Issues

The central issue was whether the trial court properly granted each defendant separate sets of peremptory challenges under Rule 47(c). The rule requires co-parties to join in challenges unless there is a substantial controversy between them. The Court also addressed the appropriate standard of review for such determinations and constitutional challenges to the rule’s application.

Court’s Analysis and Holding

The Court established that trial courts have only limited discretion when determining whether a substantial controversy exists between co-parties. Using the four-factor analysis from State v. Pena, the Court found that Rule 47(c) determinations involve relatively straightforward fact patterns with established precedent, warranting close appellate review. The Court affirmed that defendants presenting a united front against the plaintiff—without cross-claims, separate litigation, or fundamentally incompatible defenses—do not meet the substantial controversy standard. Internal disputes between co-parties and separate representation alone are insufficient.

Practice Implications

This decision clarifies that Utah courts will closely scrutinize peremptory challenge allocations to prevent unfair advantages. Practitioners should document any actual cross-claims or fundamentally divergent defense strategies when seeking separate challenges for co-parties. The Court’s presumption of prejudice when challenges are erroneously allocated means that such errors typically warrant new trials, emphasizing the importance of getting these determinations right at the trial level.
