Questione giuridica chiave
Whether the appeal was admissible because federal law or international law conferred a right to a residence permit
Decisione estratta
No such enforceable right existed under the foreign nationals legislation or the cited ordinances, so the appeal could not proceed on that basis.
Motivazione estratta
Swiss authorities have discretion on residence permits unless a specific federal or treaty right exists; the cited provisions did not create a right beyond the statute.
