Questione giuridica chiave
Whether the public-law appeal was admissible against the revocation/non-renewal of the residence permit and the requested declaratory relief.
Decisione estratta
The appeal was admissible only insofar as the first appellant could invoke a statutory entitlement based on marriage; the declaratory requests and the hardship-claim arguments were inadmissible.
Motivazione estratta
Under former ANAG, a foreign spouse of a Swiss citizen had a prima facie right under Art. 7(1) ANAG. However, declaratory relief required a specific legal interest, which was not shown. The hardship argument fell outside the admissible scope under the BGG exclusion rules.
