When is expert testimony required in Utah slip-and-fall cases? Fox v. BYU Explained
Summary
Mrs. Fox fell on BYU stairs and sued for negligence, claiming defective stairs caused her injury. However, Mrs. Fox told EMTs her knee ‘gave out’ and disclosed pre-existing osteoarthritis. The trial court dismissed the case for lack of expert testimony to establish causation between the alleged defective stairs and her injury.

Analysis
Background and Facts
Mrs. Fox fell while descending stairs at BYU’s Harman Building and broke her leg. After the fall, BYU volunteer EMTs responded and treated her. During their assessment, Mrs. Fox repeatedly told the EMTs that she felt her knee “go out” as she descended, explaining that she had been previously diagnosed with osteoarthritis in her right knee with missing cartilage. The EMTs documented these statements in a report that Mrs. Fox signed. The Foxes later sued BYU for negligence, claiming defective stairs caused the fall.
Key Legal Issues
The case presented two primary issues: whether expert testimony was required to establish causation when the plaintiff’s own statements suggested alternative medical causes for her fall, and whether EMT reports containing the plaintiff’s statements were admissible under Utah Rule of Evidence 803(4) despite Utah Code § 78-27-33’s restrictions on statements obtained by adverse parties.
Court’s Analysis and Holding
The Utah Court of Appeals affirmed the dismissal, holding that expert testimony was necessary because Mrs. Fox’s own statements introduced medically complex factors beyond ordinary lay knowledge. The court noted that Mrs. Fox presented two plausible theories of causation—defective stairs versus knee failure from osteoarthritis—and without expert testimony, determining causation would require impermissible speculation. The court also ruled that Rule 803(4) impliedly modified Utah Code § 78-27-33 to allow admission of statements made for medical diagnosis and treatment, even when obtained by agents of the adverse party.
Practice Implications
This decision emphasizes that even in seemingly straightforward slip-and-fall cases, expert testimony becomes essential when the plaintiff’s own statements introduce alternative medical explanations for the injury. Practitioners should carefully evaluate whether their client’s statements to medical personnel could undermine a lay testimony approach to proving causation. The ruling also clarifies that medical statements to emergency responders are generally admissible under Rule 803(4), regardless of the responders’ relationship to adverse parties.
