Pleading follows the Wyoming Rules of Civil Procedure. Wyo. Stat. § 16-3-114(a) (1977, Rev. 1982). But see Wyo. Stat. § 16-3-114(b). The Supreme Court has the authority to determine the content of the record upon review, pleadings to be filed, the time and manner for filing pleadings, records and other documents and the extent to which supplemental testimony and evidence may be taken or considered by the district court. Such rules would supersede existing statutory provisions.
