Key legal question
Whether the administrative appeal against refusal to renew the residence permit was admissible.
Extracted holding
The appeal was not admissible because Swiss law provided no enforceable right to the permit.
Extracted reasoning
Under Art. 100(1)(b)(3) OG, administrative recourse in foreign police matters is excluded where no federal-law right to the permit exists; Art. 4 ANAG leaves renewal to administrative discretion.
