Questão jurídica principal
Whether the cantonal court violated the duty to give reasons by limiting the wife's share of the surplus without sufficient explanation.
Decisão extraída
The reasoning requirement was satisfied because the wife could understand and challenge the decision, and the cantonal court sufficiently indicated why it limited her share.
Fundamentação extraída
A decision need only briefly state the decisive considerations; it need not address every argument. The cantonal court expressly relied on discretionary assessment to cap the surplus share.
