Can Utah courts award prejudgment interest on settlement amounts? Iron Head Construction v. Gurney Explained

In Iron Head Construction v. Gurney, the Utah Court of Appeals addressed the novel question of whether a trial court can award prejudgment interest based on a settlement amount when the parties specifically reserve the interest issue for judicial determination.

Background and Facts

The Gurneys hired Iron Head Construction for home construction and remodeling work under a written contract for $168,558. After disputes arose over additional work and payment, Iron Head filed suit alleging breach of contract, quantum meruit, and unjust enrichment. During trial, the parties settled all claims for $43,500 but specifically reserved the issue of prejudgment interest for the trial court to decide. The trial court awarded Iron Head $12,835 in prejudgment interest, calculated from December 31, 2000.

Key Legal Issues

The primary issue was whether a trial court can award prejudgment interest based on a settlement amount, particularly when the underlying claims included equitable theories like quantum meruit and unjust enrichment. The Gurneys argued that prejudgment interest cannot be awarded on settlement amounts because settlements do not establish liability or determine damages through judicial findings.

Court’s Analysis and Holding

The Court of Appeals applied the traditional Fell factors to determine whether prejudgment interest was appropriate. Under Fell v. Union Pacific Railway Co., prejudgment interest may be awarded when damages: (1) can be calculated with mathematical accuracy; and (2) are complete as of a particular date. The court distinguished this case from typical settlements, noting that the parties did not reach a global settlement but specifically reserved the prejudgment interest issue for judicial determination. The court found that Iron Head’s damages, based on evidence of hours worked, materials, invoices, and labor costs, could be calculated with mathematical accuracy despite disputes over the amounts. The court also determined that damages were complete as of December 31, 2000, when construction work ceased.

Practice Implications

This decision provides important guidance for structuring settlements in cases where prejudgment interest may apply. Practitioners should explicitly address whether prejudgment interest is included in settlement amounts or whether the issue should be reserved for separate judicial determination. The ruling also clarifies that equitable claims like quantum meruit are not categorically excluded from prejudgment interest awards if they satisfy the Fell factors. However, as Judge Orme’s dissent highlights, determining the appropriate basis for prejudgment interest on settlement amounts presents unique challenges in distinguishing between amounts owed for work performed versus litigation avoidance premiums.
