Key legal question
Whether the public-law appeal was admissible despite the foreigner-law exception and lack of an current interest.
Extracted holding
The appeal was admissible because the appellant plausibly invoked potential rights under Art. 50(1)(b) LEtr and Art. 8(1) ECHR; the lack of current interest did not preclude review since the cantonal judgment also addressed renewal.
Extracted reasoning
Potential entitlement suffices for admissibility under Art. 83(c)(2) LTF. Although the permit had expired, the case remained justiciable because the challenged judgment also ruled on renewal.
