Sale of Goods Ordinance

(1)
Where there is a contract for the sale of unascertained or future goods by
                description, and goods of that description, and in a deliverable state, are
                unconditionally appropriated to the contract, either by the seller with the assent
                of the buyer, or by the buyer with the assent of the seller, the property in the
                goods thereupon passes to the buyer. Such assent may be express or implied, and may
                be given either before or after the appropriation is made.
(2)
Where, in pursuance of the contract, the seller delivers the goods to the buyer
                or to a carrier or other bailee (whether named by the buyer or not) for the purpose
                of transmission to the buyer, and does not reserve the right of disposal, he is
                deemed to have unconditionally appropriated the goods to the contract.
