Can Utah courts exclude expert witnesses for inadequate disclosures? Al-Imari v. UDOT Explained

The Utah Court of Appeals recently addressed the critical question of when trial courts should exclude expert witnesses for inadequate disclosures under Rule 26(a)(4)(A). In Al-Imari v. UDOT, the court reversed both an order excluding an expert witness and a subsequent summary judgment ruling, emphasizing that sanctions must be proportional to the violation.

Background and Facts

The Al-Imaris were injured when their vehicle encountered oil or another slick substance on Highway 89 during road construction work performed by Staker for UDOT. They sued both entities for negligence, claiming inadequate road maintenance and insufficient warning signage. In their expert disclosures, the Al-Imaris designated a professional engineer but provided only a list of topics he would address—such as “obligations of construction contractors in sealing roadways” and “factors contributing to the underlying accident”—without stating his actual opinions on these matters.

Key Legal Issues

The central issues were whether the expert designation violated Rule 26(a)(4)(A)’s requirement for “a brief summary of the opinions to which the witness is expected to testify,” and if so, whether exclusion was the appropriate sanction. Rule 26(d)(4) mandates exclusion unless the failure is harmless or justified by good cause.

Court’s Analysis and Holding

The Court of Appeals agreed the disclosure was deficient because it contained “only a list of topics” rather than a summary of the expert’s actual opinions. However, the court found the district court abused its discretion by imposing the “ultimate sanction” of exclusion. The court emphasized that harmlessness should be assessed at the time of the court’s ruling, not when the violation occurred. Here, defendants had sufficient information to make an informed choice between a report and deposition, and any harm could have been cured by allowing defendants to depose the expert at plaintiffs’ expense. The court noted this was not a complete failure to disclose but rather “an infirmity contained within a timely disclosure that was otherwise completely in compliance.”

Practice Implications

This decision provides important guidance on proportional sanctions in discovery violations. While courts retain broad discretion in managing discovery, they must exercise it “with reason and in good conscience,” considering whether lesser sanctions could remedy any harm. The ruling also clarifies that expert designations need not include exhaustive detail but must go beyond mere topic lists to include at least brief summaries of anticipated opinions. Practitioners should ensure expert disclosures clearly state what the expert will conclude, not just what subjects they will address.
