Questione giuridica chiave
Whether the public-law appeal was admissible despite the general exclusion for residence-permit cases
Decisione estratta
The husband had a statutory and Convention-based claim to renewal, so the appeal was admissible.
Motivazione estratta
Art. 42 AuG gave a prima facie entitlement because he lived with his Swiss spouse; any possible extinction due to a revocation ground affected the merits, not jurisdiction.
