Questione giuridica chiave
Whether the cantonal court exceeded the scope of the federal remand when recalculating the wife's maintenance capacity and income.
Decisione estratta
Yes. The remand court was bound by the prior federal findings and could not revisit the wife's previously established earning capacity of CHF 1,675.20 per month.
Motivazione estratta
Under the binding effect of a remand, the lower court may only address matters left open by the remand and may not aggravate the position of the successful federal appellant on points already definitively decided.
