Questione giuridica chiave
Whether the 2009 LSVA tariff complied with the statutory cost-coverage limit under Art. 7 SVAG in light of congestion costs
Decisione estratta
The court could not determine with sufficient certainty whether the tariff respected Art. 7 SVAG because the congestion-cost assumptions underlying the tariff remained unclear.
Motivazione estratta
Both the Ecoplan/Infras and ProgTrans studies used incorrect theoretical premises, so the factual basis for the tariff calculations was uncertain. The case had to be sent back for further clarification and reassessment.
