Questione giuridica chiave
Whether the appeal on spousal maintenance remained justiciable after the appellant's death.
Decisione estratta
The maintenance claim became moot because the duty to pay maintenance ends on the death of either the entitled or the obligated person.
Motivazione estratta
Death of X. extinguished the maintenance obligation under Art. 130(1) ZGB, so the federal appeal could no longer be decided on the merits.
