Key legal question
Whether the public-law appeal was admissible in an immigration family-reunification dispute.
Extracted holding
The public-law appeal was admissible because the appellant could invoke Art. 8 ECHR; the subsidiary constitutional complaint was therefore inadmissible.
Extracted reasoning
A foreigner with a secure right of residence as spouse of a Swiss national may rely on Art. 8 ECHR, and the children could in principle derive a reunification claim from that provision.
