When any appeal is taken, the appeal may be placed upon the argument list by direction of any party interested by intervention or otherwise. Depositions of witnesses, and other evidence to be used at the argument, may be taken on behalf of any party, before any person competent to administer an oath, upon rule for that purpose, served upon the opposite party or such party's counsel. After hearing argument the court shall file its finding of fact and conclusions of law, and enter judgment in accordance therewith. If, after argument, the court shall deem any question or questions of fact so doubtful, under the evidence submitted, as to render it desirable that an issue be directed as to such question or questions to be tried by a jury, the court may direct such an issue.
