Questione giuridica chiave
Whether new facts justified transferring parental authority and custody to the mother
Decisione estratta
No. The alleged changes did not show that the existing joint parental authority and alternating custody endangered the children or had to be altered for their welfare.
Motivazione estratta
The cantonal findings showed no proven parenting deficits by the father; the cited incidents did not establish serious danger, and the social services report supported continued shared parental responsibility.
