Kernrechtsfrage
Whether the administrative law appeal was admissible against the refusal to renew the residence permit.
Extrahierter Entscheid
The appeal was admissible only because the applicant, as the spouse of a Swiss citizen, could invoke a statutory entitlement under Art. 7 LDDS; the challenge to the original administrative decision was inadmissible.
Extrahierte Begründung
A permit refusal is generally not appealable unless federal or treaty law grants a right to the permit. Art. 7 para. 1 LDDS conferred such a right, while the attack on the first-instance decision was barred by the devolutive effect.
