Kernrechtsfrage
Whether the public-law appeal was admissible under Article 83(c)(2) LTF despite the foreigner's permit claim.
Extrahierter Entscheid
The appeal was admissible because a potentially defensible right under the EU-Switzerland Free Movement Agreement could not be excluded at the admissibility stage.
Extrahierte Begründung
A potential treaty-based right to residence is sufficient to avoid the exclusion clause; the existence of the substantive right is examined on the merits.
