Key legal question
Whether the cantonal court violated the right to a reasoned decision by failing to address the husband's allegation that the wife lived in concubinage.
Extracted holding
Yes. The court had to address the admissibility and merits of the allegation because, if proven and timely raised, it could affect the wife’s minimum vital standard and thus the maintenance calculation.
Extracted reasoning
The court could not ignore a fact specifically invoked on appeal without stating why it was disregarded. This omission breached the duty to give reasons under Article 29 of the Constitution.
