Key legal question
Admissibility of the complaint by each appellant
Extracted holding
The complaint was admissible only for the father and the minor son; it was inadmissible for the adult son because he could not rely on a protected dependency relationship under Article 8 ECHR.
Extracted reasoning
A right under Article 8 ECHR may arise for the father because of his minor Swiss child, and the minor son may derive a claim through the father if such right exists. The adult son had no special dependency relationship and therefore no standing.
