Key legal question
Whether the appellant had standing to challenge the refusal of the canton change request.
Extracted holding
He was not entitled to appeal because he lacked a legally protected interest in the refusal of the mother's canton change request.
Extracted reasoning
The children normally follow the custodial parent. The mother, as the custodial parent, may change her residence within Switzerland under Art. 301a(2) ZGB without the other parent's consent unless this seriously affects parental care or contact. Since the appellant lives in Zurich, the return to Zurich would not disadvantage contact rights; rather, it would be favorable. Therefore no protected interest existed.
