Kernrechtsfrage
Whether the administrative appeal against refusal to renew the residence permit was admissible.
Extrahierter Entscheid
The appeal was admissible because the appellant, as spouse of a Swiss citizen and family member, could invoke a statutory and Convention-based claim to a residence permit.
Extrahierte Begründung
The existence of a possible extinguishing ground goes to the merits, not to admissibility; family life under the Constitution and the ECHR also supported standing.
