Kernrechtsfrage
Whether the constitutional complaint was admissible against the refusal to renew the residence permit.
Extrahierter Entscheid
No. The applicant had no legally protected interest because neither federal law nor the Constitution granted him a residence permit claim.
Extrahierte Begründung
A constitutional complaint requires a legally protected interest. The invoked constitutional provisions did not confer a substantive entitlement to renewal, and the complaint did not meet the standing requirement.
