Question juridique clé
Whether turnover generated by the related clothing company could be attributed to the appellant for WUST purposes
Solution extraite
Yes. The clothing company was not economically and outwardly independent, so its manufacturing turnover was attributable to the appellant.
Motifs extraits
Although formally separate, the two businesses lacked clear outward separation; the related company acted as a mere extension of the appellant, with shared premises, management, invoicing practice, and no genuine independent price calculation.
