Questão jurídica principal
Whether the subsidiary constitutional complaint was admissible despite no entitlement to renewal of the residence permits
Decisão extraída
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.
Fundamentação extraída
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.
