Questão jurídica principal
Whether the cantonal court violated Art. 145 CC by refusing a psychiatric expert assessment of the mother in a child-custody dispute.
Decisão extraída
Yes. The medical file was too fragmentary to assess the mother's mental condition and parenting capacity reliably; a psychiatric expert opinion was the appropriate means of proof.
Fundamentação extraída
Under Art. 145 CC, the judge investigates ex officio, but need not accept every evidence offer. Here, the existing reports gave only a partial picture and even the treating psychiatrist had first recommended an expert opinion. Without expert evidence, the facts were established incompletely.
