Questione giuridica chiave
Whether the administrative law appeal against refusal to extend the residence permit was admissible.
Decisione estratta
The appeal was admissible because the appellant could rely in principle on his marriage to a Swiss citizen under Art. 7(1) ANAG.
Motivazione estratta
A still-existing marriage to a Swiss citizen generally gives a right to renewal of the residence permit; therefore federal administrative law review was open.
