Kernrechtsfrage
Whether the public law appeal was admissible against revocation of a settlement permit.
Extrahierter Entscheid
The appeal was admissible because a settlement permit is generally a right to retain under federal law.
Extrahierte Begründung
A public law appeal is excluded only where no federal or international right exists; a settlement permit revocation is reviewable because the holder generally has a claim to maintenance of the permit.
