Can plaintiffs sue additional defendants after settling with some parties following trial? Richardson v. Navistar International Explained

The Utah Supreme Court addressed whether plaintiffs can pursue additional defendants after settling with some parties following a trial that allocated fault under Utah’s comparative fault statute. The case arose from a certified question from the Tenth Circuit Court of Appeals.

Background and Facts
In 1989, a motor vehicle collision involving a Toyota Land Cruiser and Navistar truck resulted in multiple deaths and injuries to the Richardson children. Plaintiffs filed a negligence action against various defendants in state court. After some defendants settled, the case proceeded to trial on liability issues only. The jury allocated 15% fault to plaintiffs’ mother and 85% among the remaining defendants. Crucially, the parties settled before final judgment was entered, and the case was dismissed with prejudice. Plaintiffs later filed a separate federal action against Navistar and Toyota based on product liability theories.

Key Legal Issues
The central issue was whether plaintiffs could maintain a subsequent tort action against additional known defendants after entering into a settlement following trial where a jury had allocated 100% of fault among parties under Utah’s Liability Reform Act.

Court’s Analysis and Holding
The Utah Supreme Court emphasized that the jury’s fault allocation was never reduced to final judgment because the parties settled first. The court clarified that settlement before final judgment means the jury’s verdict had “no binding or preclusive effect on any party or court.” The court answered the certified question affirmatively, holding that parties may settle with some defendants without jeopardizing their right to seek redress from others.

Practice Implications
This decision confirms that settlements with some defendants do not preclude subsequent litigation against other potential tortfeasors. Practitioners should note that the court expressly reserved judgment on the effect of fully litigated claims (to final judgment) under the Liability Reform Act. The distinction between settlement and judgment becomes critical in determining whether collateral estoppel or other preclusion doctrines apply to subsequent litigation.
