Key legal question
Whether the company was liable as a manufacturer-wholesaler because the Umsatz of the spin-off company were attributable to it as an economic enterprise unit.
Extracted holding
Yes. The many indicators showed that the two companies were not genuinely separate in business, organization, staff, accounting, or external appearance; the B.________ AG's turnover was therefore attributable to the appellant.
Extracted reasoning
The Court held that under the WUStB separate legal entities are taxed separately only if they act independently in commerce. Here there was no real spatial, organizational, managerial, or commercial separation; the Court therefore upheld attribution of the manufacturing turnover to the appellant.
