Kernrechtsfrage
Whether the public-law appeal was admissible against the refusal to reconsider the 23 April 2012 immigration decision.
Extrahierter Entscheid
The appeal in public law was inadmissible only insofar as it attacked the merits of the residence-permit issue; it could be examined solely as to the legality of the refusal to reconsider.
Extrahierte Begründung
A review refusal can be challenged only as to that refusal itself. The appellant failed to invoke arbitrariness or to show any concrete breach of cantonal procedural law or formal constitutional guarantees.
