Questione giuridica chiave
Whether the public-law appeal was admissible despite the foreigner-law limitation on no-entitlement cases.
Decisione estratta
The appeal was admissible because the marriage could, in principle, found a right under former Art. 7 al. 1 LSEE to renewal and even establishment, and the abuse-of-right question belonged to the merits.
Motivazione estratta
A potential right exists where a foreign spouse of a Swiss national invokes Art. 7 al. 1 LSEE; abuse of rights does not defeat jurisdiction at the admissibility stage.
