Question juridique clé
Whether the daughter should be placed under the father's custody instead of the mother's custody
Solution extraite
The cantonal court did not misuse its discretion in allocating custody of the daughter to the mother; the father's objections did not show a federal-law violation.
Motifs extraits
Child welfare prevails under Art. 133 ZGB. The Federal Court is bound by the cantonal findings of fact and does not review evidentiary assessment. The father merely challenged those findings and failed to substantiate any breach of the investigative principle or any arbitrary exercise of discretion.
