Question juridique clé
Whether the public law appeal against refusal to renew the residence permit was admissible
Solution extraite
The public law appeal was inadmissible to the extent it challenged the case without an enforceable statutory entitlement; a subsidiary constitutional complaint was also unavailable.
Motifs extraits
No renewed permit claim could be derived independently from the economic freedom, and the relevant challenge should have been directed against the Regierungsrat's final decision; thus the procedural requests for extending time or curing the appeal were rejected.
