A proposal is revoked—
(1) by the communication of notice of revocation by the proposer to the other party;
(2) by the lapse of the time prescribed in such proposal for its acceptance, or, if no time is so prescribed, by the lapse of a reasonable time, without communication of the acceptance;
(3) by the failure of the acceptor to fulfil a condition precedent to acceptance; or
(4) by the death or insanity of the proposer, if the fact of his death or insanity comes to the knowledge of the acceptor before acceptance.
Legal Commentary & Landmark Judgments: Section 6
Section 6 of the Indian Contract Act, 1872 prescribes four exhaustive statutory modes through which a proposal is revoked prior to acceptance, delineating the operational boundaries of unilateral offer termination by notice, lapse of time, breach of condition precedent, or proposer incapacity.
When advising bidders seeking to withdraw tenders or quotes, transmit formal revocation through instantaneous, verifiable electronic means (registered corporate email, digitally signed communication) prior to the dispatch of the acceptance or Letter of Intent. If the tendering authority attempts to forfeit earnest money deposit (EMD), plead Section 6 to establish that the offer was extinguished, defeating contractual penalties unless statutory bidding rules independently authorize pre-acceptance forfeiture.
