You cannot present new evidence on appeal. You can ask the district court though to enlarge the findings to ask whether the court considered and ruled on all the evidence in its ruling.
Appeals rule only on the court record- which is the court file, transcripts, and evidence. The idea is that the appellate courts determine whether the lower court erred in its ruling. If new evidence is provided to the appellate courts and was not ruled on by the lower court, the appellate courts cannot determine whether an error was made or not. So appellate courts cannot hear new evidence.
