Kernrechtsfrage
Whether the public law appeal was admissible against the refusal to renew the residence permit.
Extrahierter Entscheid
It was inadmissible because no federal or international law conferred a right to the requested permit.
Extrahierte Begründung
The applicant could not rely on Art. 7 LSEE, nor on Arts. 8 and 12 ECHR, nor on the OLE or federal migration directives, since the permit remained within cantonal discretion under Art. 4 LSEE.
