Question juridique clé
Whether the cantonal court could reconsider child support ex officio although the wife's appeal attacked only spousal maintenance.
Solution extraite
Yes. In child-related matters, the court is not bound by the parties' conclusions and may review the maintenance issue ex officio on appeal.
Motifs extraits
The maxime d'office applies fully to questions concerning children, including at appellate level, and reformatio in pejus is not barred in this area.
