As amended through April 30, 2019
Rule 1.03 - Failure to comply with rules (a) The timely filing of a notice of appeal, which complies with Rule 2.07(a), is jurisdictional. The failure to comply with any other rule of appellate procedure, or any order of court, does not affect the validity of the appeal, but is ground only for such action as the appellate court deems appropriate, including but not limited to: refusal to consider the offending party's contentions; assessment of costs; monetary sanctions; award of attorney fees; dismissal; and affirmance. (b) A party's failure to comply with these rules may result in imposition of sanctions, including but not limited to: (1) Appellant or cross appellant who fails to provide a notice of appeal to the appellate court as required by Rule 2.01(a), or whose notice of appeal does not include the appendix required by Rule 2.07(b) and (c), may be subject to a monetary sanction when the case is docketed in the appellate court. (2) A party who fails to file the required designation or certification of record in the trial court contemporaneously with filing the brief in the appellate court may be subject to a monetary sanction upon notification of non-compliance by the clerk of the trial court. See Rule 3.05. For Supreme Court general orders on sanctions, see www.courts.state.wy.us/WSC/Clerk. Amended April 6, 2015, effective July 1, 2015.
