Key legal question
Admissibility of the subsidiary constitutional complaint against refusal of a residence permit
Extracted holding
The complaint was inadmissible because the appellants lacked a legally protected interest and therefore lacked standing.
Extracted reasoning
No legal entitlement to the requested immigration permit existed; under Art. 115 lit. b BGG the absence of a protected interest bars standing, and the invoked equal-treatment and arbitrariness objections could not create such a position.
