54. Liability of party preventing event on which contract is to take effect

When a contract contains reciprocal promises and one party to the contract prevents the other from performing his promise, the contract becomes voidable at the option of the party so prevented; and he is entitled to compensation from the other party for any loss which he may sustain in consequence of the non-performance of the contract.

Illustration

A and B contract that B shall execute certain work for A for $1,000. B is ready and willing to execute the work accordingly but A prevents him from doing so. The contract is voidable at the option of B; and, if he elects to rescind it, he is entitled to recover from A compensation for any loss which he has incurred by its non-performance.
