Question juridique clé
Whether the children had to be heard again under Art. 12 CRC / Art. 144 ZGB
Solution extraite
The son had already been heard by the first instance, and the half-sister was not directly affected in a way requiring a hearing; no violation was shown.
Motifs extraits
Art. 12 CRC is directly applicable but does not go beyond Art. 144 ZGB. A renewed hearing was unnecessary because the son's views were already before the court, and the half-sister's interests were only indirect and not materially at stake.
