If, upon the hearing of an appeal in any proceeding, it appears that the appeal is frivolous, immaterial or intended for delay, the court may, either upon motion of a party or of its own motion, award against the appellant double costs from the time when the appeal was taken and also interest from the same time at the rate of twelve per cent a year on any amount which has been found due for debt and damages, or which he has been ordered to pay, or for which judgment has been recovered against him, or may award any part of such additional costs and interest.
