Goods Act 1958

Where there is an agreement to sell goods on the terms that the price is to be fixed by the valuation of a third party, and such third party cannot or does not make such valuation, the agreement is avoided: Provided that if the goods or any part thereof have been delivered to and appropriated by the buyer he must pay a reasonable price therefor.

Where such third party is prevented from making the valuation by the fault of the seller or buyer the party not in fault may maintain an action for damages against the party in fault.
