Ascertainment of price (Section 9 of the Sale of Goods Act, 1930): \nBy virtue of Section 9, the price in a contract of sale may be-\n(1) fixed by the contract, or \n(2) agreed to be fixed in a manner provided by the contract, e.g., by a valuer, or \n(3) determined by the course of dealing between the parties.\nAgreement to sell at valuation (Section 10):\nSection 10 provides for the determination of price by a third party. \n1. Where there is an agreement to sell goods on the terms that price is to be fixed by the valuation of a third party and that third party either does not or cannot make such valuation, the agreement is thereby avoided. However, a buyer who has received and appropriated the goods, must pay a reasonable price for them.\n2. In case the third party is prevented from making the valuation by the default of either party, the party not at fault may maintain a suit for damages against the party in fault. \n(i) In the instant case, Priya handed over the keys of her two wheeler to Sony and it was decided between them that price of the vehicle will be fixed by Priya’s father. However, Priya’s father refused to fix the price as he did not want Priya to sell her vehicle. As the keys have already been handed over to Sony, Priya cannot take back the keys from Sony and Sony shall pay reasonable price to Priya for the two-wheeler.\n(ii) If Priya had not handed over the vehicle to Sony, the contract could have been avoided as Priya’s father refused to fix the price of the vehicle.
