Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible against the refusal of a residence permit for the applicant's mother.
Decisione estratta
The complaint was inadmissible because the mother had no legal entitlement to the residence permit, and the applicant therefore lacked a legally protected interest.
Motivazione estratta
Without a statutory entitlement to the permit, an appeal in public law was excluded; subsidiary constitutional complaint was the only possible federal remedy, but it requires the invocation and substantiation of a constitutional right and a legally protected interest. The applicant did not identify any violated constitutional right and could not challenge the merits of the permit refusal.
