Introduction – Offer and Acceptance

Every legally enforceable contract begins with an offer and its corresponding acceptance. These two foundational elements determine whether parties have truly reached an agreement capable of creating legal obligations. Without a valid offer and acceptance, no contract can come into existence under the Indian Contract Act, 1872. Understanding their nature, rules, and judicial interpretation is vital to appreciating how consent forms the basis of contractual relationships in both personal and commercial contexts.

Definition and Key Legal Terms

The Indian Contract Act, 1872 lays down the statutory foundation for offer and acceptance. Section 2(a) defines a proposal or offer as when one person signifies to another his willingness to do or abstain from doing anything, with a view to obtaining the assent of that other to such act or abstinence. Section 2(b) defines acceptance as when the person to whom the proposal is made signifies his assent thereto, the proposal becomes a promise.

In simpler terms, an offer expresses willingness, while acceptance transforms that willingness into a binding promise. Thus, an agreement is the result of an offer made by one party and acceptance by the other.

Historical Background and Evolution

The principles governing offer and acceptance in India are derived from English common law, which established the doctrines of mutual consent and communication of intention. During colonial times, Indian law absorbed these doctrines into the Indian Contract Act, 1872. Over the years, Indian courts have refined these concepts, aligning them with contemporary realities like electronic communication and digital agreements.

Statutory Framework and Rules

The Act lays down specific rules regarding valid offer and acceptance to ensure clarity and mutual understanding between parties.

A valid offer must be:

  1. Made with the intention to create legal relations.
  2. Certain and definite in terms.
  3. Communicated to the offeree (Sec. 4).
  4. Capable of acceptance.
  5. Made voluntarily and not by coercion or fraud.

Offers may be express, when stated in words (spoken or written), or implied, when inferred from conduct. Section 9 of the Act recognizes both forms. Offers can also be general (open to the public, such as advertisements) or specific (directed to an individual).

Acceptance, under Section 2(b), must:

  1. Be absolute and unqualified (Sec. 7).
  2. Be expressed in the prescribed manner or a usual mode.
  3. Be communicated to the offeror (Sec. 4).
  4. Occur while the offer is still subsisting and not revoked.
  5. Correspond exactly to the terms of the offer (mirror image rule).

Landmark Case Laws

In Carlill v. Carbolic Smoke Ball Co. (1893) 1 QB 256, the company’s public advertisement promising £100 to anyone who contracted influenza after using its product was held to constitute a valid offer to the world. The plaintiff’s act of using the product as prescribed was deemed valid acceptance. This case laid down that general offers can be accepted by anyone who fulfills the stated conditions.

In Lalman Shukla v. Gauri Dutt (1913) 11 All LJ 489, the Allahabad High Court held that an offer must be known to the acceptor at the time of acceptance. Since the servant was unaware of the reward offer when he found the missing boy, there was no valid acceptance.

In Felthouse v. Bindley (1862) 11 CB (NS) 869, the English court established that silence does not amount to acceptance. A person cannot be bound by an offer merely because they failed to reject it.

In Bhagwandas Goverdhandas Kedia v. Girdharilal Parshottamdas & Co. (1966) 1 SCR 656, the Supreme Court of India clarified that a contract is concluded where the acceptance is communicated and received, establishing the significance of communication in contract formation.

Communication and Revocation

Sections 3, 4, and 5 of the Act govern the communication of offer, acceptance, and revocation. Communication of an offer is complete when it comes to the knowledge of the offeree. Communication of acceptance is complete as against the proposer when it is put in the course of transmission (such as posting a letter) and as against the acceptor when it comes to the proposer’s knowledge. An offer can be revoked any time before the acceptance becomes complete as against the offeror, while acceptance can be revoked before it reaches the proposer.

Contemporary Relevance and Practical Application

With the advent of electronic and online contracting, the rules of offer and acceptance have evolved significantly. The Information Technology Act, 2000 recognizes electronic communication as valid means for forming contracts. Courts have upheld click-wrap and browse-wrap agreements, where a person’s act of clicking “I Agree” or continuing to use a website constitutes acceptance. The essence of mutual consent remains unchanged; only the medium of communication has transformed.

Comparative Analysis

In Indian law, communication of acceptance is effective only when received by the offeror, aligning more with English common law. However, under the postal rule recognized in England, acceptance is complete upon posting. Indian courts have accepted this principle only in limited contexts, emphasizing actual communication in most cases.

Critical Perspectives

While the classical theory of offer and acceptance provides certainty, critics argue that it may not adequately address modern forms of contracting such as automated digital agreements or AI-based negotiations. Legal scholars suggest a more flexible approach that recognizes the realities of instant communication and implied assent in digital transactions.

Conclusion

Offer and acceptance together form the very heart of contract law. They embody the principle of mutual consent—the meeting of minds—that transforms a mere proposal into a legally enforceable promise. Though technological advancement continues to reshape how agreements are formed, the underlying doctrine of free and informed consent remains as essential today as it was in 1872.
