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