At one stage during the appeal Riviera suggested that this had caused Campbell to assume the burden of proving that the property passed to Mr Boland before the accident, but this appears unsound and the suggestion was indeed withdrawn. In consequence the onus lay on Riviera to rebut any relevant presumption arising under the applicable law of sale of goods.
49 The parties and the trial judge assumed the Sales of Goods Act 1923 (NSW) to be applicable. Since no plea of any applicable non-Australian law was advanced, and no proof of it was offered, and since the only other possible provision was the Sale of Goods Act 1896 (Qld), the provisions of which are not materially different from those of the NSW Act, there is no reason to treat the approach of the parties and the trial judge as wrong.
50 The Sale of Goods Act 1923 provides:
"6. (1) A contract of sale of goods is a contract whereby the seller transfers or agrees to transfer the property in goods to the buyer for a money consideration called the price. There may be a contract of sale between one part owner and another.
(3) Where under a contract of sale the property in the goods is transferred from the seller to the buyer, the contract is called a sale; but where the transfer of the property in the goods is to take place at a future time, or subject to some condition thereafter to be fulfilled, the contract is called an agreement to sell.
(4) An agreement to sell becomes a sale when the time elapses or the conditions are fulfilled, subject to which the property in the goods is to be transferred.
21. Where there is a contract for the sale of unascertained goods, no property in the goods is transferred to the buyer unless and until the goods are ascertained.
22. (1) Where there is a contract for sale of specific or ascertained goods, the property in them is transferred to the buyer at such time as the parties to the contract intend it to be transferred.
(2) For the purpose of ascertaining the intention of the parties regard shall be had to the terms of the contract, the conduct of the parties, and the circumstances of the case.
23. Unless a different intention appears, the following are rules for ascertaining the intention of the parties as to the time at which the property in the goods is to pass to the buyer.
Rule 1. Where there is an unconditional contract for the sale of specific goods in a deliverable state, the property in the goods passes to the buyer when the contract is made, and it is immaterial whether the time of payment or the time of delivery, or both, be postponed.
Rule 2. Where there is a contract for the sale of specific goods, and the seller is bound to do something to the goods for the purpose of putting them in a deliverable state, the property does not pass until such thing be done and the buyer has notice thereof.
Rule 3. Where there is a contract for the sale of specific goods in a deliverable state, but the seller is bound to weigh measure test or do some other act or thing with reference to the goods for the purpose of ascertaining the price, the property does not pass until such act or thing be done and the buyer has notice thereof.
Rule 4. Where goods are delivered to the buyer on approval or on 'sale or return' or other similar terms, the property therein passes to the buyer:
(a) when he signifies his approval or acceptance to the seller, or does any other act adopting the transaction;
(b) if he does not signify his approval or acceptance to the seller, but retains the gods without giving notice of rejection, then if a time has been fixed for the return of the goods, on the expiration of such time, and if no time has been fixed, on the expiration of a reasonable time. What is a reasonable time is a question of fact.
Rule 5.
(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.
25. Unless otherwise agreed, the goods remain at the seller's risk until the property therein is transferred to the buyer, but when the property therein is transferred to the buyer, the goods are at the buyer's risk, whether delivery has been made or not:
Provided that where delivery has been delayed through the fault of either buyer or seller, the goods are at the risk of the party in fault as regards any loss which might not have occurred but for such fault:
Provided also that nothing in this section shall affect the duties or liabilities of either seller or buyer as a bailee of the goods of the other party.
35. (1) Where in pursuance of a contract of sale the seller is authorised or required to send the goods to the buyer, delivery of the goods to a carrier, whether named by the buyer or not, for the purpose of transmission to the buyer, is prima facie deemed to be a delivery of the goods to the buyer.
(2) Unless otherwise authorised by the buyer, the seller must make such contract with the carrier on behalf of the buyer as may be reasonable, having regard to the nature of the goods and the other circumstances of the case. If the seller omit[s] so to do, and the goods are lost or damages in course of transit, the buyer may decline to treat the delivery to the carrier as a delivery to himself, or may hold the seller responsible in damages.
(3) Unless otherwise agreed, where goods are sent by the seller to the buyer by a route involving sea transit under circumstances in which it is usual to insure, the seller must give such notice to the buyer as may enable him to insure them during their sea transit, and if the seller fails to do so, the goods shall be deemed to be at his risk during such sea transit."
