Must plaintiffs provide evidence when defendants contest jurisdiction with sworn declarations? Nelson v. Phillips Explained

In Nelson v. Phillips, the Utah Supreme Court addressed a critical procedural question about personal jurisdiction challenges: what happens when defendants submit sworn declarations contradicting a plaintiff’s jurisdictional allegations? The court’s ruling provides essential guidance for practitioners handling out-of-state defendants.

Background and Facts

Justin Nelson sued his deceased wife’s family members and friends for defamation, alleging they conspired at the funeral to damage his reputation by suggesting he was responsible for his wife’s death. All defendants were out-of-state residents who moved to dismiss for lack of personal jurisdiction. Crucially, each defendant supported their motion with sworn declarations specifically denying the conspiracy allegations that formed the basis for jurisdiction. Nelson chose not to provide any counter-evidence, instead relying solely on his unverified complaint allegations and arguing the court should accept them as true.

Key Legal Issues

The case presented two main issues: whether Utah courts can exercise conspiracy jurisdiction over out-of-state defendants, and what evidentiary burden plaintiffs face when defendants contest jurisdictional facts with sworn testimony. The court applied its framework from Raser Technologies, which requires plaintiffs to plead with particularity that defendants are conspiracy members who could reasonably anticipate being haled into Utah court.

Court’s Analysis and Holding

The court held that when defendants submit documentary evidence controverting jurisdictional allegations, the burden shifts to plaintiffs to provide prima facie evidence supporting jurisdiction. Plaintiffs cannot rely solely on complaint allegations when faced with specific sworn denials. Here, the defendants’ declarations eliminated the factual basis for conspiracy jurisdiction, leaving only allegations that defendants attended the funeral and made social media posts—insufficient to establish conspiracy membership or reasonable anticipation of Utah litigation.

Practice Implications

This ruling emphasizes the importance of early evidence gathering in personal jurisdiction disputes. When defendants present sworn declarations, plaintiffs must immediately respond with their own evidence rather than relying on pleadings alone. The decision also reinforces that conspiracy jurisdiction requires specific factual allegations, not mere conclusory statements about meetings of the minds.
