Questione giuridica chiave
Whether the appeal in public law matters was admissible despite the immigration context
Decisione estratta
It was admissible insofar as the appellant invoked a possible entitlement under Art. 50(1)(b) AuG; the challenge to the migration office decision itself was inadmissible because it was replaced by the cantonal judgment.
Motivazione estratta
A colorable statutory right based on important personal reasons creates standing for access to the federal appeal. Under the devolutive effect, the lower administrative decision is superseded by the cantonal judgment.
