Can Utah courts impose discovery sanctions against parties who didn't request them? Cook Martin Poulson PC v. Smith Explained

2026 UT App 54
No. 20230024-CA
April 9, 2026
Affirmed in part and Reversed in part

Summary

An accounting firm sued a former shareholder-employee for breach of employment and shareholder agreements after he worked for former clients. The district court dismissed the defendant’s third-party complaint as a discovery sanction and granted summary judgment for the plaintiff while excluding the defendant’s declarations and evidence under rule 26.

Analysis

In a significant ruling addressing discovery sanctions and evidence exclusion, the Utah Court of Appeals reversed multiple aspects of a district court’s summary judgment ruling in an employment and shareholder dispute.

Background and Facts

Daniel Smith worked as an accountant for Cook Martin Poulson PC (CMP) and later became a shareholder. After CMP terminated Smith’s employment in 2014, he began providing accounting services to former CMP clients. CMP sued Smith for breaching his employment and shareholder agreements’ noncompete provisions. Smith filed counterclaims against CMP and a third-party complaint against other shareholders. During discovery, Smith failed to provide initial disclosures and violated a court discovery order. The district court sanctioned Smith by dismissing his third-party complaint and excluding his evidence under rules 26 and 37, then granted summary judgment for CMP.

Key Legal Issues

The appeal presented several critical issues: whether courts can impose rule 37 sanctions against parties who didn’t move for them; when a party’s failure to disclose himself as a witness is harmless under rule 26; and whether summary judgment was appropriate when disputed facts remained about contract breaches and share repurchases.

Court’s Analysis and Holding

The court reversed the dismissal of Smith’s third-party complaint, holding that rule 37 sanctions require a motion from the party seeking sanctions. Since the other shareholders never moved for sanctions, the court lacked discretion to dismiss Smith’s claims against them. The court also found Smith’s failure to disclose himself as a witness was harmless because he had previously testified and submitted declarations, providing adequate notice to opposing parties. When considering Smith’s excluded evidence, the court concluded genuine factual disputes existed regarding whether CMP first breached the employment agreement and whether it had properly repurchased Smith’s shares.

Practice Implications

This decision emphasizes the importance of proper procedural compliance in seeking discovery sanctions. Practitioners must ensure that all parties who would benefit from sanctions either file their own motions or formally join existing motions. The ruling also demonstrates that harmlessness analysis under rule 26 considers the totality of circumstances, including whether parties had adequate notice despite technical disclosure failures. For summary judgment practice, the decision reinforces that courts must consider all admissible evidence and cannot exclude evidence based on improper sanctions.

Case Number

No. 20230024-CA

Date Decided

April 9, 2026

Outcome

Affirmed in part and Reversed in part

Holding

A district court cannot impose discovery sanctions under rule 37 against non-moving parties, and a party’s failure to disclose himself as a witness may be harmless when the opposing party has adequate notice of the potential testimony.

Standard of Review

Abuse of discretion for discovery sanctions under rule 37; abuse of discretion for rule 26 harmlessness determinations; correctness for interpretations of the Utah Rules of Civil Procedure; correctness for summary judgment rulings

Practice Tip

When seeking discovery sanctions under rule 37, ensure that all parties who would benefit from the sanctions file their own motions or formally join existing motions, as courts cannot impose sanctions sua sponte in favor of non-moving parties.
