Wyo. Stat. § 27-14-614
The director may appeal to the district court from any order or judgment of the hearing examiner awarding compensation or declining to award compensation although he was not a party to the proceedings before the hearing examiner, without the necessity of presenting any petition for reopening of a case to the hearing examiner. After the appeal is perfected, the hearing examiner may stay the execution of the order or judgment appealed from without requiring any bond. The attorney general or his assistant shall represent the director in all cases. All the costs of the new hearings granted upon petition of the director and all costs of appeals conducted by the director shall be paid by the worker's compensation account except such costs as the court in its discretion shall assess against any of the other parties to the cause.
