Are Utah's wildlife importation requirements unconstitutionally vague? Clearfield City v. Hoyer Explained

In Clearfield City v. Hoyer, the Utah Court of Appeals addressed whether Utah’s wildlife importation requirements are unconstitutionally vague when applied to reptile imports. The case arose from “Operation Slither,” a Division of Wildlife Resources investigation targeting illegal reptile possession and trade.

Background and Facts

Ryan Hoyer, an amateur herpetologist specializing in rubber boa snakes, was convicted of violating Utah Code section 23-20-3 for unlawfully possessing approximately 38 rubber boa snakes imported into Utah without required documentation. The state alleged Hoyer failed to obtain both a certificate of veterinary inspection and an entry permit as required by Utah Administrative Code rule R657-53-21(2). After being acquitted in justice court on some charges but convicted on the importation charge, Hoyer appealed to district court, where he was again convicted following a trial de novo.

Key Legal Issues

Hoyer’s sole argument on appeal was that Utah Code section 23-20-3, as it incorporates various administrative rules, is void for vagueness. He specifically argued that Utah Administrative Code rule R58-1-4, which requires veterinary inspections for “all animals and poultry,” does not clearly apply to reptiles because other subsections distinguish “wildlife” from “animals” generally.

Court’s Analysis and Holding

The Court of Appeals applied the standard void-for-vagueness test, requiring that a penal statute define criminal conduct with sufficient definiteness that ordinary people can understand what is prohibited. The court found no vagueness in the statutory scheme, noting that rule R657-53-21(2) clearly states that “any amphibian or reptile” requires both inspections and permits before importation. The court rejected Hoyer’s interpretation that would limit the veterinary inspection requirement only to diseased animals or those from quarantined areas, finding that reptiles are clearly “animals” within any reasonable reading of the rules.

Practice Implications

This decision reinforces that constitutional challenges to statutes face a strong presumption of validity. Courts will not find vagueness merely because a defendant can “inject doubt” where none would exist for ordinary readers. For practitioners defending wildlife violations, focus on whether the specific conduct was actually prohibited rather than attempting to parse definitional ambiguities in related administrative rules.
