Question juridique clé
Whether the appellant was an economic seller within Art. 124 LT / Art. 12 LAID
Solution extraite
Yes. The 28 May 2004 deed gave him durable power to dispose of the PPP units, so he occupied the factual position of owner.
Motifs extraits
The seller was bound to sell to buyers proposed by him, could not refuse them, and had to adapt the deed to each sale; this went beyond mere brokerage or auxiliary promotion.
