Questione giuridica chiave
Whether the appeal in public law matters was admissible against the cantonal judgment refusing renewal of the study residence permit and ordering removal.
Decisione estratta
The appeal in public law matters was inadmissible because no federal or international right to the requested permit existed, and removal orders are excluded from that remedy.
Motivazione estratta
No enforceable entitlement followed from Art. 27 AuG; therefore Art. 83 lit. c BGG barred the ordinary appeal.
