Kernrechtsfrage
Whether the Swiss-Italian border agreement allows customs exemption in a parallel zone along the whole border.
Extrahierter Entscheid
No. The agreement establishes a radial border zone tied to listed areas and the nearest border crossing, not a general parallel zone.
Extrahierte Begründung
Text, structure, annex lists, and long-standing practice show a radial zone limited to the territories enumerated in the annex.
