Section 11. Effect of Conditions.—
Where the obligation of either party to a contract to sell or a sale is subject to any condition which is not performed, such party may refuse to proceed with the contract or sale or he may waive performance of the condition. If the other party has promised that the condition should happen or be performed, such first mentioned party may also treat the non-performance of the condition as a breach of warranty.
Where the property in the goods has not passed, the buyer may treat the fulfillment by the seller of his obligation to furnish goods as described and as warranted expressly or by implication in the contract to sell as a condition of the obligation of the buyer to perform his promise to accept and pay for the goods.
