If, on the date specified by the clerk, the appeal is not ready for hearing, a judge of the Court of Appeal may, after giving the parties an opportunity to be heard, declare the appeal abandoned, unless a valid reason is presented by one of the parties. The judge may in that case make any order he sees fit.
