Kernrechtsfrage
Whether the constitutional complaint is admissible against the refusal to renew the residence permits
Extrahierter Entscheid
It is inadmissible because the appellants had no legal entitlement to the renewal of the permits and therefore lacked standing to challenge the merits.
Extrahierte Begründung
Without a right to permit renewal, administrative judicial review was unavailable; a constitutional complaint could not be used to attack the substance of the decision under the guise of arbitrariness.
