Can underinsured motorist insurers offset workers' compensation benefits? Truck Ins. Exch. v. Rutherford Explained

Background and Facts

Danny Rutherford suffered extensive injuries when his work van was struck by an underinsured driver. He filed claims with both his employer’s workers’ compensation insurer, Mid Century Insurance, and Truck Insurance Exchange (TIE), which provided underinsured motorist (UIM) coverage for his employer. While his medical expenses exceeded $250,000, Mid Century paid only $183,628.81 for medical expenses plus benefits for lost wages and permanent disability. Rutherford sought full UIM benefits from TIE, arguing the insurer could not reduce its payments based on workers’ compensation benefits received.

Key Legal Issues

The case centered on interpreting two provisions of Utah Code section 31A-22-305.3(4)(c): subsection (i), which states UIM coverage “is secondary to the benefits provided by” workers’ compensation, and subsection (iii), which provides that UIM coverage “may not be reduced by benefits provided by workers’ compensation insurance.” The fundamental question was whether an injured employee could recover double recovery by obtaining full UIM benefits despite having already received workers’ compensation payments for the same damages.

Court’s Analysis and Holding

The Utah Supreme Court applied the term-of-art meaning of “secondary coverage,” interpreting it as synonymous with “excess coverage” that applies only after primary benefits are exhausted. The Court distinguished between coverage limits (which cannot be reduced by workers’ compensation payments) and actual benefits payable (which must avoid duplication). The Court rejected Rutherford’s arguments based on the collateral source rule and liberal construction of insurance statutes, emphasizing that double recovery is generally disfavored in insurance law.

Practice Implications

This decision clarifies that UIM insurers cannot reduce their policy limits based on workers’ compensation benefits but may offset actual payments to prevent double recovery. Practitioners should carefully analyze the extent of workers’ compensation coverage when calculating UIM liability, particularly noting that workers’ compensation typically covers only 66⅔% of average weekly wages. The decision also demonstrates the Court’s reluctance to permit double recovery absent clear statutory authorization, reinforcing the importance of precise drafting in insurance coverage disputes.
