Questione giuridica chiave
Whether the federal appeal was admissible despite the request only seeking annulment of the cantonal judgment.
Decisione estratta
Although the request was formally deficient, admissibility followed because the reasoning made it clear that the appellant contested the maintenance obligation in full.
Motivazione estratta
A purely annulment request is generally insufficient in a reformative appeal, but an exception applies when the relief sought is unmistakable from the submissions.
