Can mediation confidentiality agreements bar testimony about unrelated settlement discussions? Moss v. Parr Waddoups Brown Gee & Loveless Explained

Background and Facts

In Moss v. Parr Waddoups Brown Gee & Loveless, defendants represented a company in litigation against Yanaki for misappropriation of proprietary information. During that case, defendants obtained ex parte discovery orders authorizing seizure of records from Yanaki and his wife Moss’s home. Plaintiffs subsequently filed a federal civil rights lawsuit challenging the seizure. During a California mediation of the underlying case, parties signed a mediation confidentiality agreement that broadly prohibited disclosure of “all statements made during the course of the mediation” and stated that “no aspect of the mediation shall be relied upon or introduced as evidence in any proceeding.” Plaintiffs later sued defendants in state court, claiming they had reached an oral settlement agreement during the mediation to resolve the federal civil rights case.

Key Legal Issues

The case presented two critical issues: whether the mediation confidentiality agreement was facially ambiguous regarding its scope, and whether hearsay testimony about defendants’ alleged acceptance of a settlement offer was admissible to prove the breach of contract claim. The trial court found the agreement ambiguous and admitted contested testimony, denying defendants’ motion for partial summary judgment.

Court’s Analysis and Holding

The Utah Court of Appeals reversed, applying the framework from Daines v. Vincent for determining contractual ambiguity. The court held that competing interpretations must be “reasonably supported by the language of the contract” to find facial ambiguity. Here, the agreement’s plain language prohibited disclosure of “all statements” and “any aspect” of the mediation without distinguishing by subject matter. The court rejected plaintiffs’ argument that the agreement only applied to discussions about the underlying case, finding this interpretation unreasonable given the broad contractual language. Additionally, the court held that testimony regarding defendants’ alleged acceptance constituted inadmissible double hearsay, as the mediator’s statement was essential to prove contract formation and no hearsay exception applied.

Practice Implications

This decision reinforces that courts will strictly enforce mediation confidentiality agreements according to their plain language. Practitioners should carefully draft such agreements with precise language regarding scope and any intended exceptions. When broad confidentiality language is used, courts will not resort to extrinsic evidence to create ambiguity where the contractual terms are otherwise plain. The ruling also highlights the evidentiary challenges in proving oral settlement agreements when key witnesses are bound by confidentiality restrictions.
