What duty standard applies when contractors create artificial conditions on land? Sumsion v. J. Lyne Roberts and Sons, Inc. Explained

In Sumsion v. J. Lyne Roberts and Sons, Inc., 2019 UT 14, the Utah Supreme Court clarified the proper framework for analyzing whether contractors owe a duty to third parties injured by artificial conditions created on another’s land.

Background and Facts

Becky Sumsion worked for the City of Springville and regularly accessed pumps in a splash pad pump house using a ladder installed by contractor J. Lyne Roberts and Sons, Inc. (JLR) and manufactured by H&H Steel Fabricators. In June 2015, Sumsion fell from the ladder and broke her ankle. She sued both contractors for negligence in designing and constructing the ladder. The district court granted summary judgment for defendants, concluding they owed Sumsion no duty under the four-factor test from AMS Salt Industries v. Magnesium Corp. of America.

Key Legal Issues

The primary issue was which legal framework governs duty analysis when contractors create artificial conditions on land that later injure third parties. Sumsion argued that Tallman v. City of Hurricane established a categorical duty under the Restatement (Second) of Torts. Defendants contended the four-factor test from AMS Salt Industries applied, requiring analysis of foreseeability, likelihood of injury, burden of guarding against harm, and consequences of imposing the burden.

Court’s Analysis and Holding

The Utah Supreme Court reversed and remanded, holding that the Restatement (Second) of Torts framework from Tallman controls these cases, not the AMS Salt factors. The court explained that Tallman “unambiguously” adopted the Restatement approach for contractors who create artificial conditions on land. However, the court declined to definitively resolve the duty question due to inadequate briefing on which specific Restatement sections applied. The court noted that AMS Salt and Slisze v. Stanley-Bostitch were distinguishable because they involved different factual scenarios and theories of liability.

Practice Implications

This decision provides crucial guidance for practitioners handling contractor liability cases. When artificial conditions are created on land, attorneys must frame duty arguments around Restatement sections 385, 394-398, and 403-404, rather than generic duty factors. The court’s remand emphasizes the importance of thorough briefing on which specific Restatement provision applies and how its elements establish duty. Practitioners should carefully analyze whether the chattel involved is inherently dangerous, negligently manufactured, or falls under another Restatement category, as each triggers different duty standards.
