Questione giuridica chiave
Whether the case was admissible as a federal public-law appeal despite being filed as subsidiary constitutional appeal.
Decisione estratta
The subsidiary constitutional appeal was treated as a public-law appeal because the dispute concerned extinction of an existing settlement permit not excluded by Art. 83 let. c ch. 2 LTF.
Motivazione estratta
A public-law appeal is open against a declaration of lapse of a permit that would otherwise continue to have effect; the permit here was a CE/AELE settlement permit valid throughout Switzerland.
