Questione giuridica chiave
Whether the administrative appeal was admissible because a right to family reunification existed under ANAG/BVO.
Decisione estratta
No enforceable right arose from Art. 17 ANAG or Arts. 38-39 BVO, so the appeal was not admissible on that basis.
Motivazione estratta
Family reunification under Art. 17 ANAG presupposed a settlement permit, which the applicant never held. The BVO did not create a right beyond the statute; the cantonal authority retained discretion.
