Key legal question
Admissibility of the administrative law appeal against refusal to renew a residence permit
Extracted holding
The appeal was admissible insofar as the applicant relied on a statutory right derived from marriage to a Swiss citizen; admissibility is separate from whether that right has been lost through abuse.
Extracted reasoning
Under the foreigners law, an appeal is excluded unless the applicant can invoke a federal-law or treaty-based entitlement. Art. 7(1) LDDS conferred such a right, so the federal appeal was open.
