Key legal question
Whether the children should remain in the father's custody or be placed with the mother
Extracted holding
The children remained in the father's custody; the challenged custody allocation was not arbitrary.
Extracted reasoning
The cantonal court made its own child-welfare assessment and could prioritize stability of living arrangements after about 23 months with the father. Both parents had impaired but basically present parenting ability, and both had behaved problematically toward the children. Given the children's clear wish to stay with the father and the risky effects of a custody change, maintaining the status quo was permissible.
