Scheme of the Indian Contract Act, 1872: Chapter-Wise Arrangement, Part I General Principles and Part II Special Contracts

The Indian Contract Act is arranged with more deliberation than its jumbled section numbering suggests. The statute moves in a single sequence from the birth of a contract to its death: first how an agreement is formed, then when it becomes enforceable, then how performance is made and excused, then what follows from breach, and finally the detailed rules for four named transactions. The two blank blocks left by repeal disguise this order but do not disturb it. Knowing the scheme allows any provision to be located by asking which stage of the contractual life it belongs to.

1. The Two Parts

The Act divides into two parts which are studied separately and applied together.

Part I, Sections 1 to 75: the general principles. These apply to every contract whatever its subject matter, and answer the questions of formation, validity, performance and breach.
Part II, Sections 124 to 238: the special contracts. These supply additional rules for indemnity and guarantee, bailment and pledge, and agency. They supplement Part I and never displace it.

Between the two parts lies the gap left by the repeal of Sections 76 to 123 by the Sale of Goods Act, 1930, and after Section 238 the gap left by the repeal of Sections 239 to 266 by the Indian Partnership Act, 1932. The Act therefore ends at Section 238 although it was enacted with 266 sections.

2. The Chapter-Wise Scheme

The statute is formally divided into a Preliminary part followed by eleven chapters. Two of those chapters no longer exist in the Act.

Chapter	Sections	Subject
Preliminary	1 to 2	Short title, extent, commencement and the saving of usage and custom; the definitions in Section 2(a) to 2(j)
Chapter I	3 to 9	Of the communication, acceptance and revocation of proposals
Chapter II	10 to 30	Of contracts, voidable contracts and void agreements: the conditions of enforceability, capacity, free consent, lawful consideration and object, and the agreements expressly declared void
Chapter III	31 to 36	Of contingent contracts
Chapter IV	37 to 67	Of the performance of contracts
Chapter V	68 to 72	Of certain relations resembling those created by contract, commonly called quasi-contracts
Chapter VI	73 to 75	Of the consequences of breach of contract
Chapter VII	76 to 123	Sale of goods. Repealed by the Sale of Goods Act, 1930
Chapter VIII	124 to 147	Of indemnity and guarantee
Chapter IX	148 to 181	Of bailment, including pledge in Sections 172 to 179
Chapter X	182 to 238	Agency
Chapter XI	239 to 266	Of partnership. Repealed by the Indian Partnership Act, 1932

3. Part I in Detail: The Life of a Contract

3.1 Definitions: Section 2

Section 2 is the hinge of the statute. Its ten clauses build a chain in which each term is defined by reference to the one before: a proposal under 2(a), accepted, becomes a promise under 2(b); the person making it is the promisor and the person accepting the promisee under 2(c); what moves at the promisor's desire is consideration under 2(d); a promise or set of promises forming the consideration for each other is an agreement under 2(e); an agreement enforceable by law is a contract under 2(h). Clauses 2(g), 2(i) and 2(j) then classify the agreements and contracts that fail, as void, voidable, and contracts that become void.

3.2 Formation: Sections 3 to 9

Chapter I fixes the mechanics of agreement. Section 3 states how a proposal, acceptance or revocation is communicated. Section 4 fixes the moment of completion of communication, which differs for the proposer and the acceptor and is the foundation of the postal rule in India. Section 5 states when a proposal and an acceptance may be revoked, and Section 6 the modes of revocation. Sections 7 and 8 deal with what makes an acceptance effective, requiring it to be absolute and unqualified and recognising acceptance by performance of conditions. Section 9 distinguishes express from implied promises.

Section 4, Indian Contract Act, 1872 — completion of communication

The communication of a proposal is complete when it comes to the knowledge of the person to whom it is made.

The communication of an acceptance is complete, as against the proposer, when it is put in a course of transmission to him so as to be out of the power of the acceptor; as against the acceptor, when it comes to the knowledge of the proposer.

The communication of a revocation is complete, as against the person who makes it, when it is put into a course of transmission to the person to whom it is made so as to be out of the power of the person who makes it; as against the person to whom it is made, when it comes to his knowledge.

📖 Bhagwandas Goverdhandas Kedia v. Girdharilal Parshottamdas & Co., AIR 1966 SC 543

Facts: A contract for the supply of cottonseed cake was negotiated by telephone between Ahmedabad and Khamgaon. The offer was made from Khamgaon and the acceptance was spoken from Ahmedabad and heard at Khamgaon. The question was where the contract was made, which determined which court had jurisdiction.

Held: The majority held that the rule in Section 4, framed with postal and telegraphic communication in mind, does not apply to instantaneous communication. Where the parties are in direct and instantaneous contact, the contract is made at the place where the acceptance is heard by the proposer. The contract was therefore made at Khamgaon.

Ratio: Sections 3 and 4 govern non-instantaneous communication. For telephone and equivalent instantaneous media the ordinary rule applies, and acceptance is effective when and where it is received.

3.3 Validity: Sections 10 to 30

Chapter II is the largest block in Part I and states the conditions on which an agreement becomes a contract. Its internal order tracks the ingredients listed in Section 10.

Section 10 states the requirements: free consent, competent parties, lawful consideration, lawful object, and the agreement not being expressly declared void. The second paragraph saves every law requiring writing, attestation or registration.
Sections 11 and 12 deal with capacity, excluding minors, persons of unsound mind and those disqualified by any law to which they are subject.
Sections 13 to 22 deal with consent and its absence. Section 13 defines consent as ad idem; Section 14 defines free consent; Sections 15 to 18 define coercion, undue influence, fraud and misrepresentation; Sections 19 and 19A make the contract voidable at the option of the injured party; Sections 20 to 22 deal with mistake, and mistake of fact by both parties as to a matter essential to the agreement makes it void.
Sections 23 to 25 deal with lawfulness of object and consideration, severance where part is unlawful, and the general rule that an agreement without consideration is void with three exceptions.
Sections 26 to 30 declare specified classes of agreement void: restraint of marriage, restraint of trade, restraint of legal proceedings, uncertain agreements, and wagering agreements.

3.4 Contingent contracts: Sections 31 to 36

Chapter III deals with a contract to do or not to do something if a collateral event happens or does not happen. Section 31 defines it; Sections 32 to 36 state when such contracts may be enforced, by reference to whether the event has happened, has become impossible, or is impossible at the time the agreement is made. Contracts of insurance and of indemnity are the commonest practical examples.

3.5 Performance: Sections 37 to 67

Chapter IV is the longest chapter in the Act and covers the entire middle life of a contract. Its blocks are readily identified: the obligation to perform and the effect of tender in Sections 37 to 39; by whom performance must be made in Sections 40 to 45; time and place of performance in Sections 46 to 50; reciprocal promises in Sections 51 to 58; appropriation of payments in Sections 59 to 61; the discharge of contracts by novation, rescission and alteration in Sections 62 to 67; and, within that block, Section 56, which states the rule on agreements to do impossible acts and on supervening impossibility.

3.6 Quasi-contract: Sections 68 to 72

Chapter V is headed 'of certain relations resembling those created by contract', and the heading is deliberate. These obligations arise by operation of law, not by agreement, and the drafters avoided calling them contracts for that reason. Section 68 deals with necessaries supplied to a person incapable of contracting; Section 69 with payment by a person interested in the payment of money which another is bound to pay; Section 70 with the obligation of a person enjoying the benefit of a non-gratuitous act; Section 71 with the responsibility of a finder of goods; and Section 72 with money paid or a thing delivered by mistake or under coercion.

📖 Mahabir Kishore v. State of Madhya Pradesh, (1989) 4 SCC 1

Facts: Amounts had been collected by the State which it was not entitled in law to retain. The claimants sought restitution, and the question was the juridical basis on which such a claim rests under the Act.

Held: The Supreme Court explained that Chapter V rests on the principle of unjust enrichment, and set out its three requisites: the defendant must have been enriched by the receipt of a benefit; the enrichment must be at the expense of the plaintiff; and the retention of the enrichment must be unjust. Section 72 gives statutory effect to this principle in relation to money paid under mistake or coercion.

Ratio: The obligations in Sections 68 to 72 are restitutionary and quasi-contractual. They do not depend on any agreement between the parties and are measured by the defendant's gain rather than by the plaintiff's loss.

3.7 Breach: Sections 73 to 75

Chapter VI closes Part I. Section 73 states the measure of compensation for loss caused by breach, confining it to loss which naturally arose in the usual course of things or which the parties knew when they made the contract to be likely to result, and excluding remote and indirect loss. Section 74 governs a sum named in the contract as payable on breach and the stipulation by way of penalty, allowing reasonable compensation not exceeding the amount named. Section 75 preserves the right of a party who rightfully rescinds to compensation.

⚠ Section 74 does not reproduce the English distinction

English law distinguishes between a liquidated damages clause, which is enforceable as agreed, and a penalty, which is not enforceable at all. Section 74 abolishes that distinction: in both cases the court awards reasonable compensation not exceeding the sum named. The named sum therefore operates as a ceiling rather than as an entitlement, and the party claiming must still establish that loss has been suffered, except where the nature of the case makes proof of actual loss impossible.

4. Part II in Detail: The Special Contracts

4.1 Indemnity and guarantee: Sections 124 to 147

Section 124 defines a contract of indemnity as one by which one party promises to save the other from loss caused by the conduct of the promisor himself or of any other person, and Section 125 states the indemnity holder's rights when sued. Sections 126 to 147 then deal with guarantee: its definition and the three parties to it, continuing guarantees and their revocation, the nature and extent of the surety's liability, the surety's rights of subrogation and contribution, and the circumstances in which a surety is discharged.

4.2 Bailment and pledge: Sections 148 to 181

Section 148 defines bailment as the delivery of goods by one person to another for some purpose, on a contract that they shall, when the purpose is accomplished, be returned or otherwise disposed of according to the directions of the person delivering them. Sections 149 to 171 state the duties of bailor and bailee, the standard of care, the consequences of unauthorised use or mixture, and the bailee's lien. Sections 172 to 179 deal with pledge as a species of bailment in which goods are delivered as security. Sections 180 and 181 deal with suits by bailor or bailee against a wrongdoer.

4.3 Agency: Sections 182 to 238

Chapter X is the longest in the Act. Sections 182 to 189 deal with the appointment and authority of an agent, including authority in an emergency; Sections 190 to 195 with sub-agents and substituted agents; Sections 196 to 200 with ratification; Sections 201 to 210 with the termination of agency; Sections 211 to 221 with the duties of agent and principal and the agent's lien; and Sections 222 to 238 with the effect of agency on contracts with third persons, including the position of an undisclosed principal and the consequences of notice given to an agent.

5. How the Scheme Is Used

The arrangement is a working tool. A dispute is placed within the scheme by asking a short sequence of questions, and the answer identifies the chapter that governs.

Was there a proposal and an acceptance at all, and when and where did they take effect? Chapter I, Sections 3 to 9.
If there was an agreement, is it enforceable? Chapter II, Sections 10 to 30, taking capacity, consent, consideration, object and the void classes in turn.
Is the obligation dependent on a collateral event? Chapter III, Sections 31 to 36.
Has the contract been performed, excused or discharged? Chapter IV, Sections 37 to 67.
If there was no contract but a benefit has passed, does an obligation arise by law? Chapter V, Sections 68 to 72.
If the contract has been broken, what may be recovered? Chapter VI, Sections 73 to 75.
Does the transaction fall within one of the four special contracts, so that additional rules apply? Chapters VIII, IX and X.
