Revocation generally in terms mean to withdraw something. It can be anything of a good , offer, task, deal anything. It may also stand for cancellation. So revocation in the law of contracts can be defines as a remedy given to buyers if not satisfied with goods of the sellers. The buyers here are termed as offerers and revocation must be communicated to offree before acceptance. This is also the general common rule on revocation.
Section 2(e) says that an agreement is defined as a set of promises. This happens when an offer is placed by the offererand accepted by the offree. Revocation can only be done before the acceptance of a particular agreement.According to section 2e All agreements are not contracts but all contracts are agreements.
What is Acceptance:“Section 2(b) defines accpetances as :When the person to whom the proposal is made signifies his assent there to the proposal is said to be accepted. A proposal when accepted becomes a promise.Thus acceptance is the assent given to a proposal and it has the effect of covering the proposal into promise.
Communication of Acceptance: One of the good examples of actof acceptance is when the hammer falls in an auction. According to the words of Shah J An agreement does not result from a mere state of mind :intent to accept an offer or even a mental ressolveto accept an offer does not give rise to a contract.
An illustration of acceptance by consuct is the decisionof the House of Lords in Brogden v Metropolitan Railway Co. Facts: B had been supplying coal to a railway company without any formal agreement. B suggested that a formal agreement should be drawn up. The agents of both the parties met and drew up a draft agreement. It had some blanks when it was sent to B for his approval. He filled up the blanks including the name of an arbitrator and then returned it to the company. The agent of the company put the draft in his drawer and it remained there without final approval having been signified. B kept up his supply of coals but on the new terms and also recieved payment on the new terms. A dispute having risen B refused to be bound by the agreement.”
