Whether the appeal brought by one heir on behalf of the estate was admissible
The appeal was admissible because the first-instance decision did not decide the heirs' representation powers, and the appellant could in good faith assume he was authorized to act for the co-heirs.
A non-partitioned estate has no legal personality, so heirs must normally act jointly; however, the procedural situation and the authority's omission justified reliance on apparent authority under good faith.
