Can Utah courts deny expert witness substitution when the original expert withdraws before trial? Boice v. Marble Explained

In Boice v. Marble, the Utah Supreme Court addressed the challenging intersection of scheduling order compliance and expert witness substitution in medical malpractice litigation, ultimately reversing a summary judgment that resulted from overly rigid application of discovery deadlines.

Background and Facts

R. Lane Boice suffered a cervical spine injury and underwent surgery, followed by rehabilitation care under physiatrist Dr. Stephen Marble. During a wheelchair transfer at the rehabilitation facility, Boice experienced a fall that caused permanent loss of function in his left wrist, hand, and fingers. Boice sued Marble for medical malpractice, initially designating physiatrist Dr. Bruce Newton as his expert witness on the standard of care. However, approximately two months before trial, Newton informed the parties he would no longer testify. Boice moved within eight days to substitute Dr. Jayne Clark, another physiatrist, but the trial court denied the motion as untimely and subsequently granted summary judgment for Marble.

Key Legal Issues

The case presented three critical issues: whether the trial court abused its discretion in denying the motion to substitute an expert witness, whether it erred in excluding Dr. Clark from testifying as an expert, and whether it properly struck affidavits from Dr. Robert Cantu (a neurosurgeon) and nurse Colleen Lowe. The court also had to determine whether these evidentiary rulings warranted reversal of the summary judgment.

Court’s Analysis and Holding

The Utah Supreme Court found that the trial court abused its discretion in excluding the substitute expert. Unlike cases where parties simply fail to comply with deadlines, Boice had timely designated an expert who later withdrew due to unforeseen circumstances. The court emphasized that scheduling orders should accommodate legitimate exigencies while maintaining case flow efficiency. Importantly, any prejudice to Marble could have been addressed through trial continuance or cost-shifting rather than outright exclusion. The court also held that Dr. Cantu’s neurosurgery expertise qualified him to testify about post-operative care standards that overlapped with physiatry practice, satisfying the Burton v. Youngblood test for cross-specialty expert testimony.

Practice Implications

This decision provides important guidance for managing expert witness issues in complex litigation. Courts must balance enforcement of scheduling orders with fundamental fairness, particularly when circumstances beyond a party’s control necessitate changes. The ruling also clarifies that experts from related medical specialties can testify about overlapping standards of care with proper foundation. For practitioners, the case underscores the importance of immediately seeking court intervention when expert witnesses withdraw and proposing reasonable accommodations to address scheduling concerns.
