Kernrechtsfrage
Whether the Federal Administrative Court unlawfully expanded the dispute by examining group taxation issues beyond leasing transactions.
Extrahierter Entscheid
No. The dispute concerned the existence of the assessed VAT debt, so the court could examine all objective and subjective prerequisites of that liability, including the temporal scope of group membership.
Extrahierte Begründung
In administrative review, the subject of dispute is the legal relationship covered by the contested decision and the relief sought; it may be narrowed but not expanded by new claims. Here, determining whether the tax claim existed necessarily included the group-taxation prerequisites.
