Wyo. R. Prac. & P. 13.02
As amended through April 30, 2019
A writ of review may be granted by the reviewing court to review an interlocutory order of a trial court in a civil or criminal action, or from an interlocutory order of an administrative agency, which is not otherwise appealable under these rules, but which involves a controlling question of law as to which there are substantial bases for difference of opinion and in which an immediate appeal from the order may materially advance resolution of the litigation.
