What constitutes reasonable diligence under the Governmental Immunity Act? Muir v. Wasatch Front Explained

In Muir v. Wasatch Front Waste & Recycling District, the Utah Court of Appeals clarified the reasonable diligence standard under the Governmental Immunity Act (GIA), affirming dismissal of a negligence claim filed beyond the statute of limitations.

Background and Facts

Suzanne Muir was involved in a collision with a garbage truck owned by Wasatch Front Waste & Recycling District and driven by Jason Gates on March 16, 2020. She filed suit on April 12, 2022—more than two years later. The defendants moved to dismiss under the GIA’s two-year statute of limitations. Immediately after the collision, Muir received information showing the truck was insured by “Government Trust” and owned by “Wasatch Front Waste & Recycle.” Within days, her attorney identified the entity as “Wasatch Front Waste & Recycling District.”

Key Legal Issues

The central issue was whether Muir exercised reasonable diligence to determine Wasatch’s governmental status. Under the GIA, the statute of limitations is tolled until a claimant “knew, or with the exercise of reasonable diligence should have known” they had a claim against a governmental entity. The burden of proving reasonable diligence falls on the claimant.

Court’s Analysis and Holding

The Court of Appeals found Muir had inquiry notice based on two key indicators: insurance by “Government Trust” and the entity’s name containing “District.” The court emphasized that “inquiry notice occurs when circumstances arise that should put a reasonable person on guard so as to require further inquiry.” Despite having Wasatch’s phone number and email address, neither Muir nor her attorney directly contacted the entity to determine its governmental status. The court distinguished this case from situations requiring a “deep dive” internet search, noting that a simple phone call or email would have clarified Wasatch’s status.

Practice Implications

This decision reinforces Utah’s strict compliance approach to GIA requirements. Practitioners must act promptly when inquiry notice indicators suggest governmental involvement. The court’s emphasis on direct inquiry over passive research underscores that reasonable diligence requires active investigation when warning signs appear. The decision also highlights the importance of the claimant bearing the burden to prove reasonable diligence—defendants need not demonstrate the plaintiff’s failure to exercise due care.
