Questão jurídica principal
Whether the public-law appeal was admissible against the refusal to renew the residence permit under Art. 50 AuG.
Decisão extraída
The appeal was admissible only insofar as the applicant invoked Art. 50(1)(b) and (2) AuG; the request to challenge the expired permit withdrawal was moot and the subsidiary constitutional complaint regarding removal was inadmissible.
Fundamentação extraída
The original permit had already expired, the administrative decisions were replaced by the cantonal appellate judgment, and no constitutionally protected right was sufficiently invoked against the removal order.
