Questione giuridica chiave
Whether the public-law appeal was admissible against the non-renewal/revocation of the residence permit.
Decisione estratta
The appeal was inadmissible because the applicant had no enforceable right to the requested permit and the permit had already expired.
Motivazione estratta
Under Art. 83(c)(2) LTF, review is excluded where no right to the permit exists. The case had to be assessed as a refusal to renew an expired permit, and no federal or international norm gave the applicant a claim, including Art. 8 ECHR.
