Key legal question
Whether the children had to be heard under the Child Rights Convention
Extracted holding
The cantonal court did not violate Article 12 CRC by refusing to hear the children personally, because their interests were sufficiently presented through the father and the written evidence.
Extracted reasoning
In essentially written immigration proceedings, children may be represented by a parent if the parent sufficiently advances their interests; here the family situation was documented and no decisive information was shown to be missing.
