Questione giuridica chiave
Whether the wife’s need had to include health insurance premiums and whether she would receive premium reductions
Decisione estratta
The wife’s health insurance premiums could be included in her needs; the husband’s new argument about premium reductions was an inadmissible new fact.
Motivazione estratta
Maintenance proceedings are governed by the adversarial principle, not the inquisitorial principle; parties must raise relevant facts timely. The husband failed to raise the premium-reduction argument before the cantonal court, so the Federal Court could not consider it.
