Key legal question
Whether the public-law appeal was admissible despite the lack of a statutory or treaty-based right to the permit.
Extracted holding
The appeal was inadmissible because the appellant had no enforceable right to a residence permit under federal law or international law.
Extracted reasoning
Under Art. 83(c)(2) LTF, public-law appeals are excluded where no right to the permit exists. The appellant could not rely on Art. 42 LStr, because cohabitation had ceased and the family unit was not maintained, nor on Art. 50 LStr, because the marriage had not lasted three years and no serious personal reasons justified continued stay. Art. 8 ECHR was also inapplicable.
