Questão jurídica principal
Whether the cantonal court complied with the binding scope of the Federal Supreme Court's remand when calculating the husband's tax burden and maintenance.
Decisão extraída
The cantonal court did not comply, because it relied on a tax burden not corresponding to the imputed effective income fixed on remand.
Fundamentação extraída
After remand, only the husband's tax burden based on the retained income and the ad litem advance remained open. The court had to calculate taxes on the basis of the effective income of CHF 6,900 per month; using a different tax basis was arbitrary and contrary to the remand order.
