Kernrechtsfrage
Whether the public-law appeal was admissible against revocation of a residence permit in immigration matters.
Extrahierter Entscheid
The appeal was admissible because it challenged revocation of a permit that would otherwise still have been valid.
Extrahierte Begründung
Article 83(c)(2) LTF bars appeals only when no legal entitlement exists to the permit; revocation cases are different because the challenge concerns withdrawal of an already granted status.
