Key legal question
Whether the public law appeal against the refusal to renew the residence permit was admissible.
Extracted holding
The appeal was inadmissible because no statutory or treaty-based entitlement to the requested residence permit was shown.
Extracted reasoning
Although the lower court discussed possible expiry and revocation grounds, the relevant federal proceedings concerned only renewal or re-issuance of a residence permit. Under the Foreign Nationals Act, no entitlement to such discretionary permission follows from the provisions invoked, so Art. 83 lit. c no. 2 BGG barred the appeal.
