The provisions of Rules 26 through 37, relative to discovery, shall not be applicable to actions certified on appeal from the District Court except upon order issued on notice and a showing that lack of discovery will result in an injustice or undue hardship. Material obtained by the use of discovery processes in the District Court may be used at the trial of such appeals to the same extent as if such discovery had taken place in this court pursuant to these rules.
