If this Code requires that the appellate remedy be accompanied by a statement of the grounds, the person or the authority seeking the appellate remedy must indicate precisely:
which points of the decision are contested;
what grounds there are for reaching a different decision;
what evidence they wish to adduce in support of the appellate remedy.
If the submission fails to satisfy these requirements, the appellate authority shall return the same and fix a short additional period within which it may be amended. If the submission still fails to satisfy the requirements after this additional period, the appellate authority shall not consider the appellate remedy.
The incorrect designation of an appellate remedy does not adversely affect its validity.
