What burden of proof applies in Utah water right change applications? Searle v. Milburn Irrigation Company Explained

The Utah Supreme Court in Searle v. Milburn Irrigation Company clarified crucial burden of proof standards that govern water right change applications in Utah, resolving confusion that had persisted among practitioners and lower courts.

Background and Facts

The Searles purchased a water right and sought to change the point of diversion, place of use, and nature of use to meet building permit requirements for their cabin. Milburn Irrigation Company protested the application, concerned that the proposed use of the Jacobsen well could impair their senior water rights. Expert testimony presented conflicting opinions about whether the water sources were connected, with the district court ultimately finding by a preponderance of evidence that impairment would likely occur.

Key Legal Issues

The court addressed three fundamental questions: (1) whether the proper standard of proof is preponderance of evidence or some other standard; (2) whether the burden of persuasion shifts to the protestant after the applicant makes a prima facie showing; and (3) whether circumstantial evidence can defeat an application for change.

Court’s Analysis and Holding

The Supreme Court held that change applicants need only show “reason to believe” that approval will not result in impairment of vested rights—a standard analogous to probable cause in criminal proceedings. This standard falls between the low threshold Justice Oaks suggested in his Crafts dissent and the preponderance standard applicable to final rights adjudications. The court emphasized that the burden of persuasion remains with the applicant throughout the process and never shifts to protestants. Additionally, the court ruled that circumstantial evidence may be sufficient to undermine an applicant’s showing if compelling enough to make belief in non-impairment unreasonable.

Practice Implications

This decision provides clarity for water law practitioners by establishing that change applications operate under a more lenient standard than final adjudications, reflecting the Legislature’s policy favoring experimentation with water use while protecting vested rights. The “reason to believe” standard allows applicants to pursue changes without meeting the higher preponderance standard, while ensuring meaningful protection against groundless applications that could impair existing rights.
