Key legal question
Whether a public-law appeal is admissible against refusal to renew a residence permit without a legal entitlement.
Extracted holding
The complaint is inadmissible to the extent it relies on discretionary permit renewal, because no entitlement exists under federal or international law.
Extracted reasoning
Under Art. 83 lit. c no. 2 BGG, such a refusal is excluded from public-law appeal if no right to the permit exists; discretionary renewal under Art. 4 ANAG does not create an entitlement.
