Questione giuridica chiave
Whether the seasonal closure was a total traffic ban under Art. 3(3) SVG or a functional traffic restriction under Art. 3(4) SVG.
Decisione estratta
The measure was a temporary complete traffic ban on a road not open to general through traffic, thus falling under Art. 3(3) SVG.
Motivazione estratta
A winter closure prohibiting all traffic is, by its nature, a total driving ban; the Grand Council's wording about 'functional traffic restrictions' was too indeterminate and could not itself create the closure.
