Wyo. R. Prac. & P. 9.03
As amended through April 30, 2019
When a judgment or an appealable order is reversed in the appellate court, either in whole or in part, the court reversing shall proceed to render that judgment as the trial court should have rendered, or remand the cause to the trial court for judgment or additional proceedings as the appellate court may direct. If an appellate court reverses or affirms the judgment or appealable order, it shall not issue execution in causes that are brought before it but shall send a mandate to the trial court, as the case may require, for execution, and the trial court to which the mandate is sent shall proceed in the same manner as if the judgment or appealable order had been rendered in that court.
