Questão jurídica principal
Whether the appeal against spousal maintenance remained justiciable after the cantonal cassation court set aside that part and remanded it
Decisão extraída
No; the appeal became moot because the challenged spousal-maintenance ruling no longer existed and had to be reconsidered by the cantonal court.
Fundamentação extraída
Once the cassation court annulled the dispositive part on spousal maintenance and remitted it, the object of the federal appeal and the appellant's protectable interest in review lapsed.
