Can prior knowledge of danger bar premises liability claims? Reath v. Brian Head Town Explained

The Utah Court of Appeals recently addressed a fundamental question in premises liability law: whether an invitee’s prior knowledge of a dangerous condition automatically bars recovery against a landowner. In Reath v. Brian Head Town, the court reversed a summary judgment ruling and clarified the application of Restatement sections 343 and 343A to premises liability claims.

Background and Facts

Douglas Reath was injured while using Brian Head Town’s bulk water dispenser to fill his truck’s water tank. The dispenser operated at high pressure comparable to “a fire hose” (approximately 180 PSI when installed, later reduced but still dangerous). The system’s unique setup meant that if a previous user failed to close the valve after use, the next user would encounter an open valve, causing water to flow immediately at extremely high pressure when the start button was pushed.

Reath had used the dispenser about twenty-five times and generally knew to check that the valve was closed before starting. However, he admitted he wasn’t always “vigilant” about this practice. During the incident, Reath’s friend operated the keypad while Reath held the hose. When his friend pressed start with the valve open, the water pressure caused Reath to lose balance and fall, injuring his elbow and forehead.

Key Legal Issues

The central issue was whether Reath’s prior knowledge of the water pressure danger defeated the proximate causation element of his negligence claim as a matter of law. Brian Head argued that because Reath “already knew everything” about the danger, no warning could have prevented his injury. The district court agreed and granted summary judgment.

Court’s Analysis and Holding

The Court of Appeals reversed, emphasizing that causation is generally a question of fact for the jury. The court distinguished this premises liability case from products liability precedents and applied Restatement sections 343 and 343A, which govern landowner duties to invitees.

Under section 343A’s “open and obvious danger rule,” the analysis requires two steps: (1) whether the danger was known or obvious, and (2) whether the landowner should have nevertheless anticipated harm. The court explained that even when an invitee knows of a danger, the landowner may still be liable if the landowner should have anticipated that the invitee would “fail to protect themselves against it” or would “proceed to encounter the known or obvious danger.”

The court noted that reasonable minds could differ on whether Brian Head should have anticipated harm given the unpredictable nature of whether the valve would be open or closed, combined with the high water pressure and Reath’s admitted inconsistent vigilance in checking the valve.

Practice Implications

This decision reinforces that summary judgment should be granted sparingly in negligence cases, particularly on causation issues. For premises liability practitioners, the ruling clarifies that an invitee’s knowledge of a danger does not automatically defeat liability—the critical question is whether the landowner should have anticipated harm despite such knowledge.

The decision also highlights Utah’s comparative fault system, under which both parties can bear concurrent responsibility for harm. As the court noted, a plaintiff “doesn’t have to be” blameless to recover—the jury determines the weight of each party’s fault. This analysis must occur within the framework of Restatement sections 343 and 343A, not through blanket application of assumption of risk principles, which Utah has rejected as a complete bar to recovery.
