Communication, Acceptance and Revocation under Sections 3 to 9 of the Indian Contract Act, 1872: The Postal Rule, Instantaneous Communication, and Contracts Made by Telephone, Email and Electronic Message

Chapter I of the Indian Contract Act, 1872 does one thing: it fixes the moment at which a proposal, an acceptance and a revocation take effect. Everything in Sections 3 to 9 exists to answer the question when, and through it the questions where and whether. The chapter was drafted for a world of letters and telegrams, and its central provision, Section 4, is built around the delay between despatch and delivery. Where there is no such delay, as on a telephone call or an instant message, the provision does not fit and the courts have had to work out what governs instead. This topic walks through each section in order and then applies the scheme to modern media.

1. Section 3: What Amounts to Communication

Section 3 is deliberately wide. Communication is not confined to words: it extends to any act, and even to an omission, provided the party either intended to communicate by it or the act or omission had the effect of communicating. The two limbs are alternatives, which matters a great deal. A party who did not intend to communicate anything may still be held to have communicated if his conduct in fact conveyed the message, which is the statutory basis of acceptance by conduct under Section 9.

When each communication is complete, and the window it opens

2. Section 4: When Communication Is Complete

The section works by fixing two different moments for acceptance and for revocation, one for each party. A proposal, by contrast, has a single moment: knowledge. The asymmetry is the key to the whole chapter, and the table below sets it out.

2.1 What the asymmetry produces

1. The proposer is bound on despatch of the acceptance. From the moment the acceptor posts, the proposer can no longer revoke under Section 5, even though he knows nothing of the acceptance.
2. The acceptor is not bound until receipt. Because the communication is complete as against him only when it reaches the proposer, he may revoke his acceptance under the second paragraph of Section 5 at any time before that, provided his revocation reaches the proposer no later than the acceptance.
3. Risk of loss in transit falls on the proposer. A properly despatched acceptance binds him even if it never arrives, because the first limb speaks of putting it in a course of transmission and not of delivery.
4. A revocation binds nobody until it arrives. Posting a letter of revocation achieves nothing; the offeree must come to know of it.

3. The Postal Rule in India

The first limb of the acceptance rule in Section 4 is the Indian statement of the postal rule. It applies wherever there is a real interval between despatch and receipt, which in practice means post, courier and telegram. The Indian version differs from the English one in a way that consistently favours the acceptor, because English law treats a posted acceptance as binding both parties at once, while Section 4 binds only the proposer at that point and leaves the acceptor free until delivery. The rule is treated at length in the dedicated topic.

4. Instantaneous Communication

Where the parties are in direct and instantaneous contact there is no interval for the postal rule to operate on, and the reason for the rule disappears. The general principle then reasserts itself: an acceptance is effective when and where it is received by the offeror.

The Indian authority to the same effect is Bhagwandas Goverdhandas Kedia v. Girdharilal Parshottamdas & Co., AIR 1966 SC 543, where a contract was negotiated by telephone between Ahmedabad and Khamgaon. The majority held that Sections 3 and 4 were framed with post and telegraph in mind and do not govern instantaneous communication; where the parties are in direct contact the contract is made at the place where the acceptance is heard by the proposer, which was Khamgaon. The minority would have applied Section 4 literally. The majority view is the law.

5. Electronic Contracts

Email, messaging applications and web forms are not covered by Section 4 in terms, and they sit awkwardly between the two models: transmission is near-instantaneous, but the recipient is not necessarily present and the message may sit unread. The gap is filled by the Information Technology Act, 2000.

• Section 10A provides that where in a contract formation the communication of proposals, the acceptance of proposals, the revocation of proposals and acceptances, as the case may be, are expressed in electronic form or by means of an electronic record, such contract shall not be deemed unenforceable solely on the ground that such electronic form or means was used.
• Section 11 deals with attribution: an electronic record is attributed to the originator if it was sent by him, by a person authorised by him, or by an information system programmed by or on his behalf to operate automatically.
• Section 12 deals with acknowledgment of receipt where the originator has stipulated for it.
• Section 13 fixes the time and place of despatch and receipt. Despatch occurs when the record enters a computer resource outside the originator's control. Receipt occurs, where the addressee has designated a computer resource, when the record enters that resource; where he has not, when the record enters any computer resource of the addressee. An electronic record is deemed to be despatched at the originator's place of business and received at the addressee's place of business, regardless of where the servers are located.

The last point is the practically important one. Whatever the physical route of the message, Section 13 deems the contract to be concluded at the addressee's place of business, which supplies the answer for jurisdiction that Kedia had to reach by construing Section 4. Email and messaging exchanges also raise the ordinary question whether the parties reached agreement on all material terms, which the Supreme Court answered affirmatively on an email exchange in Trimex International FZE Ltd. v. Vedanta Aluminium Ltd., (2010) 3 SCC 1, holding that the absence of a later formal document does not unmake a contract the parties had already concluded.

6. Sections 5 and 6: Revocation

Section 5 fixes the outer limits. A proposal may be revoked at any time before the communication of its acceptance is complete as against the proposer, but not afterwards. An acceptance may be revoked at any time before the communication of the acceptance is complete as against the acceptor, but not afterwards. Read with Section 4, this means the proposer's window closes on despatch of the acceptance and the acceptor's window closes on its receipt.

Section 6 lists four modes by which a proposal is revoked: notice of revocation communicated by the proposer; lapse of the prescribed time or of a reasonable time; failure of the acceptor to fulfil a condition precedent to acceptance; and the death or insanity of the proposer, if the fact comes to the acceptor's knowledge before acceptance. Each is treated in the dedicated topics.

7. Sections 7 to 9: The Quality of the Acceptance

7.1 Absolute and unqualified

Section 7(1) requires the acceptance to be absolute and unqualified. A reply that varies the terms is not an acceptance but a counter offer, which destroys the original proposal.

7.2 The prescribed mode

Section 7(2) requires the acceptance to be expressed in some usual and reasonable manner, unless the proposal prescribes a manner. Where a manner is prescribed and the acceptance is made otherwise, the proposer may within a reasonable time insist on the prescribed manner, and if he fails to do so, he accepts the acceptance. The Indian rule is therefore more forgiving than a strict mirror-image approach: a departure from the prescribed mode is curable by the proposer's silence.

7.3 Acceptance within a reasonable time

Section 7 says nothing about time, but Section 6(2) supplies the limit from the other direction: an acceptance communicated after the prescribed period, or after a reasonable time where none is prescribed, comes too late because the proposal has already been revoked by lapse.

7.4 Acceptance by performance and by conduct

Section 8 provides that performance of the conditions of a proposal, or the acceptance of any consideration for a reciprocal promise offered with a proposal, is an acceptance of the proposal. Section 9 provides that a promise made in words is express and one made otherwise than in words is implied. Together they establish that assent may be signified by doing something rather than by saying something.

8. What Does Not Amount to Acceptance

• Mental acceptance. Section 2(b) requires the offeree to signify his assent. An uncommunicated decision to accept is legally nothing, and the offeror may revoke in the meantime.
• Silence. An offeror cannot stipulate that silence will be treated as acceptance, because he cannot manufacture the offeree's signification out of the offeree's inaction. Unsolicited goods sent with a demand for payment impose no liability.
• A counter offer. It fails Section 7(1) and destroys the offer.
• Acceptance in ignorance of the offer. There can be no assent to a proposal the acceptor does not know of.

9. The Position Stated Shortly

1. Section 3 defines communication widely, covering any act or omission intended to communicate or having that effect.
2. Section 4 fixes one moment for a proposal, knowledge, and two moments each for acceptance and revocation.
3. The proposer is bound when the acceptance is despatched; the acceptor is bound only when it is received, which leaves him free to revoke in the interval.
4. Risk of loss of a properly despatched acceptance falls on the proposer; a posted revocation achieves nothing until it arrives.
5. For instantaneous communication the acceptance takes effect on receipt and the contract is made where it is received, per Entores and Bhagwandas Kedia.
6. Brinkibon: receipt is the rule but not a mechanical one where transmission is delayed or the recipient is absent.
7. Section 10A of the Information Technology Act, 2000 validates electronic contracts, and Section 13 deems the record received at the addressee's place of business.
8. Section 5 fixes the limits of revocation; Section 6 lists the four modes.
9. Section 7 requires an absolute and unqualified acceptance, and a departure from a prescribed mode is cured by the proposer's silence.
10. Sections 8 and 9 allow acceptance by performance and by conduct; mental acceptance and silence do not suffice.
