Kernrechtsfrage
Whether the public-law appeal was admissible despite immigration-law limits on reviewability.
Extrahierter Entscheid
The appeal was admissible because the appellant could invoke a potential right to family reunification under Article 8 ECHR; the court did not need to determine whether a right also arose under domestic aliens law or the free movement agreement.
Extrahierte Begründung
For admissibility it was sufficient that a possible Convention-based right existed; the court did not have to examine the merits of that entitlement at this stage.
