Section 809.22 - Rule (Oral argument)(1) The court shall determine whether a case is to be submitted with oral argument or on briefs only.(2) The court may direct that an appeal be submitted on briefs only if: (a) The arguments of the appellant: 1. Are plainly contrary to relevant legal authority that appear to be sound and are not significantly challenged;2. Are on their face without merit and for which no supporting authority is cited or discovered; or3. Involve solely questions of fact and the fact findings are clearly supported by sufficient evidence; or(b) The briefs fully present and meet the issues on appeal and fully develop the theories and legal authorities on each side so that oral argument would be of such marginal value that it does not justify the additional expenditure of court time or cost to the litigant.(3) The court shall determine the amount of time for oral argument allowed to each party in a case either by general or special order.(4) On motion of any party or its own motion, the court may order that oral argument be heard by telephone.Sup.
