1 The appeal or cross-appeal is deemed to have been withdrawn if the party that has filed it:
a.
fails without excuse to attend or to arrange to be represented at the oral appeal hearing;
b.
fails to file any written submissions; or
c.
cannot be summoned.
2 If the public prosecutor or the private claimant has filed an appeal against the verdict or the sentence and the accused fails without excuse to attend the hearing, so proceedings in absentia shall be held.
3 If the private claimant has limited his or her appeal to the civil aspect and the accused fails without excuse to attend the hearing, the court of appeal shall decide as on the basis of the findings made in the main hearing before the court of first instance and the other files.
