Kernrechtsfrage
Whether the administrative law appeal against refusal of a residence permit was admissible
Extrahierter Entscheid
The appeal was admissible because the appellant, as spouse of a Swiss citizen, could rely on a statutory and Convention-based entitlement to family reunification.
Extrahierte Begründung
A refusal is reviewable by administrative law appeal where a federal-law or treaty-based entitlement exists; marriage to a Swiss citizen ordinarily creates such an entitlement under the applicable foreign-nationality rules and family-life protection.
