Key legal question
Whether the subsidiary constitutional complaint was admissible despite no entitlement to renewal of the residence permits
Extracted holding
The complaint was inadmissible because the applicants had no legally protected interest in renewal and could not invoke the ordinary constitutional complaint route for the merits.
Extracted reasoning
Without a substantive entitlement to the permit, they lacked standing under Art. 115 lit. b BGG to challenge the merits or alleged arbitrariness in the refusal.
