What happens when expert disclosure deadlines are missed in Utah medical malpractice cases? Baumann v. The Kroger Company Explained

In medical malpractice litigation, expert witness testimony is typically essential to establish the applicable standard of care and breach. The Utah Court of Appeals’ decision in Baumann v. The Kroger Company demonstrates the serious consequences of failing to meet expert disclosure deadlines under rule 26(d)(4) of the Utah Rules of Civil Procedure.

Background and Facts

Kari Baumann sued The Kroger Company and Dr. Gregory Tayler for medical malpractice, alleging hypotension due to overmedication. After her attorney withdrew, Baumann proceeded pro se. She stipulated to a discovery schedule requiring expert disclosures by June 6, 2014, with expert discovery closing September 5, 2014. Baumann failed to meet either deadline. On the day of the summary judgment hearing, she finally submitted an expert report applicable only to Kroger—without seeking court permission and contrary to the court’s prior order cutting off filings.

Key Legal Issues

The central issues were whether the district court abused its discretion in excluding Baumann’s untimely expert disclosure and whether rule 16(d) rather than rule 26(d)(4) should have governed the sanctions analysis. Baumann argued that rule 16(d)’s permissive standard should apply instead of rule 26(d)(4)’s mandatory exclusion provision.

Court’s Analysis and Holding

The Court of Appeals affirmed, holding that rule 26(d)(4) mandated exclusion of the untimely disclosed expert. The court distinguished Coroles v. State, noting that rule 26 specifically governs disclosure failures while rule 16 addresses scheduling order violations more generally. Since the district court found no good cause for the failure to disclose, exclusion was mandatory under rule 26(d)(4)’s “may not use” language.

Practice Implications

This decision reinforces Utah’s strict approach to expert disclosure deadlines. Courts will not excuse procedural violations simply to achieve economy or expedited resolution. The mandatory exclusion under rule 26(d)(4) provides powerful incentive for complete and timely disclosures. Pro se litigants receive no special consideration regarding procedural requirements and must meet the same standards as represented parties.
