Yuma Muni. Ct. Loc. R. 2.21
Rule 2.21. Default by the City
If no witness for the City, excluding the defendant, appears at the time set for hearing on a civil violation, the court shall dismiss the complaint, without prejudice, unless the court, for good cause shown or in the interest of justice, continues the hearing to another date. This rule shall not apply to cases such as civil parking infractions in which the citation constitutes prima facie evidence of the violation.
