Questione giuridica chiave
Whether the public-law appeal was admissible despite immigration-law limits on rights to a permit.
Decisione estratta
The appeal was admissible because the appellant remained formally married to a Swiss citizen, so a statutory right under former Art. 7 LDDS could still be invoked.
Motivazione estratta
For admissibility, only the formal existence of the marriage mattered; whether the right was lost through abuse of rights was a merits question.
