Questione giuridica chiave
Whether the appeal in public law matters was admissible against the refusal to renew the residence permit.
Decisione estratta
No admissible claim to renewal was shown; the challenge to a negative renewal decision was therefore outside the scope of the ordinary public-law appeal.
Motivazione estratta
Under Art. 83 lit. c no. 2 BGG, the remedy is excluded unless federal or international law grants an enforceable right. Neither legitimate expectations nor Art. 8 ECHR created such a right here.
