Questione giuridica chiave
Whether the LSVA and related declaration duties applied already in the German border clearance zone at Basel/Weil Autobahn.
Decisione estratta
Yes. The SVAG/SVAV provisions apply in the border clearance zone because LSVA enforcement is tied to border crossing and customs clearance.
Motivazione estratta
The agreement and the 1980 arrangement allow Swiss border clearance in that zone; the LSVA system is functionally linked to the border crossing, so Swiss rules govern the declaration duty already there.
