Questione giuridica chiave
Whether the cantonal court wrongly based maintenance on allegedly new facts and an increased budget item
Decisione estratta
The challenge was inadmissible because that specific objection had not been raised before the cantonal court.
Motivazione estratta
The husband attacked a different discrepancy before the Federal Court than he had before the cantonal court; the cantonal instance therefore could not review it, so the cantonal remedies were not exhausted.
