Questão jurídica principal
Whether the appeal was admissible for the eldest daughter and against the lower cantonal decisions.
Decisão extraída
No enforceable right remained for the adult daughter, and the federal appeal could only target the cantonal last-instance judgment.
Fundamentação extraída
For direct reliance on Article 8 ECHR, the child's age at the time of the federal judgment is decisive; the daughter was already adult. The federal appeal under the relevant statute lies only against the cantonal last-instance decision.
