Questão jurídica principal
Whether the cantonal court could modify the divorce judgment and award exclusive custody to the mother on the basis of new facts and the children's interests.
Decisão extraída
A custody arrangement may be changed when important new facts require it for the child's welfare; the cantonal court did not abuse its discretion in finding that each child’s situation favored exclusive custody with the mother.
Fundamentação extraída
The father's move, the children's expressed wishes, the mother's greater availability, organizational difficulties caused by the father's relocation, and the need for stability, especially for the youngest child, justified the change.
