Question juridique clé
Whether the lower court could ex officio abolish the wife's spousal maintenance despite no request by the husband
Solution extraite
No. Spousal maintenance is subject to the disposition principle; without a claim requesting reduction or suppression, the court could not modify it ex officio.
Motifs extraits
The court distinguished object-of-proceedings maxims from fact-finding maxims. ATF 128 III 411 allows shared factual findings to affect child and spouse maintenance, but does not relax the disposition principle for the spouse's claim.
