(a) A agrees with B to magically discover treasures. The agreement is not done. If a complete contract becomes impossible on either side without fault, the contract is excellent fine by the doctrine of frustration. If the following conditions are met, the doctrine of frustration can be established: if a party proves that the non-performance was caused by an obstacle that was beyond its control and that it would not reasonably have been foreseen by the party at the time of the agreement, and that it could not have avoided or overcome its effects, it is excused by the non-performance. If the obstacle is temporary, the excuse is maintained for an appropriate period during which the performance of the contract is compromised. It must be informed of the obstruction and its effects on its ability to present to the other party, otherwise the damage caused by the non-receipt disclosure could be made liable. Section 56 adopts a positive decision on frustration and does not leave the issue of frustration to the court. It is not possible to reach agreement on a change in circumstances and it has also been found that when a review of the terms of the contract, given the circumstances in which it was carried out, shows that the parties have never agreed to be bound in a fundamentally different situation that occurs unexpectedly, that the contract will no longer be bound at that time- , but does not apply in the event of actual construction in this situation; Shyam Biri Works Pvt. Ltd. v U.P. Forest Corporation, AIR 1990 SC 205. An agreement to do an impossible act in itself is a null and void.
Section 56 of the Indian Contract Act provides that any agreement to accomplish an impossible action is not has been concluded. An agreement to do an impossible act in itself is a null and void. A contract to make an act that is done after the contract becomes impossible or, because of an event that the promiseor could not prevent, becomes illegal, becomes invalid if the act becomes impossible or illegal.1 Frustration of a contract renders the contract null and void and fulfills the contractual obligations of the parties. However, section 65 of the Act states that, where an agreement has been nullified, the person who has received a benefit from such an agreement is ”obliged” to reinstate or compensate him by which he was received.
