Key legal question
Whether the public-law appeal is admissible against the expulsion and the refusal of family reunification
Extracted holding
The appeal was admissible as to the expulsion measure, but not as to family reunification because no enforceable residence right remained.
Extracted reasoning
The expulsion fell under the exceptions to Art. 83 BGG. Once the expulsion was upheld, the wife could derive no right to a residence permit, so the complaint on reunification was not cognizable.
