Questione giuridica chiave
Whether the public-law appeal against the residence permit refusal was admissible despite no statutory entitlement.
Decisione estratta
The appeal was inadmissible because the applicant had no right to the permit under federal or international law.
Motivazione estratta
Art. 44 AuG does not itself confer an entitlement; unlike Arts. 42 and 43 AuG, it only provides a basis for a permit. No other entitlement was apparent.
