Discharge of a Contract under Indian Contract Act

A contract is a legally enforceable agreement between two or more parties, under which one party agrees to do or not to do something in return for consideration. Once a valid contract is formed, it creates binding rights and obligations. The parties are expected to perform what has been promised. However, every contract reaches a stage where the contractual relationship comes to an end. When the obligations created by a contract terminate, the contract is said to be discharged.

Discharge of a contract means the termination of the contractual relationship between the parties. Once a contract is discharged, the rights, duties and obligations of the parties under that contract come to an end. The parties are no longer bound to each other by that contract, and the legally binding force of the agreement ceases.

This article explains the major modes of discharge of contract recognised under the Indian Contract Act, 1872, along with illustrations and case studies referred.

Meaning and Scope of Discharge of Contract

A contract is discharged when the obligations created by it come to an end. This termination may happen because:

• the parties have performed what was agreed,
• the parties mutually alter or cancel the agreement,
• the time for enforcing rights has expired,
• the law makes performance impossible or unlawful, or
• one party commits breach and the other party treats the contract as at an end.

The important legal consequence of discharge is that the parties are released from further performance, subject to any rights that may have already accrued, and subject to remedies that law provides in case discharge arises from breach.

The Indian Contract Act, 1872 recognises various situations in which discharge takes place. Some are normal and voluntary, such as discharge by performance or mutual agreement. Others arise due to legal events or defaults, such as discharge by breach, operation of law, lapse of time, or supervening impossibility. The law also provides remedies when discharge happens due to wrongful conduct, especially breach of contract.

Modes of Discharge of Contract

A contract may be discharged in the following major ways:

1. Discharge by performance
2. Discharge by attempted performance (tender)
3. Discharge by mutual agreement (Sections 62 and 63)
4. Discharge by breach of contract (including anticipatory breach under Section 39)
5. Discharge by operation of law
6. Discharge by lapse of time
7. Discharge by supervening impossibility or frustration (Section 56)

Each of these modes is discussed in detail below.

Discharge by Performance

Discharge by performance is the most common and natural mode of discharge. When the parties perform their respective promises, the contract comes to an end completely. Performance may be of two types:

• Actual performance
• Attempted performance

Actual Performance

Actual performance occurs when both parties to the contract perform their promises as per the terms of the agreement. Once promises are carried out within the time, manner and conditions agreed, the contract is fully discharged.

In practice, most commercial contracts are intended to end through actual performance. For example, if one party delivers goods and the other party pays the agreed price, the contract stands discharged.

In certain cases, where the contract does not depend on personal skill, the legal representatives of a deceased party may be required to perform obligations. However, where personal qualification is the foundation of the contract, death will usually end the contract, which is discussed later under discharge by operation of law and frustration.

Attempted Performance (Tender)

Attempted performance, also referred to as tender of performance, occurs when the promisor offers to perform the promise, but the promisee refuses to accept it.

The legal position is that a valid offer of performance has the same effect as performance. If a party offers to perform and the offer is not accepted by the other party, the obligations of the offering party are terminated.

This is an important protection for the promisor. The promisor cannot be made liable for non-performance when performance was genuinely offered and the promisee refused without justification.

Discharge by Mutual Agreement

A contract is created by the mutual consent of the parties, and it may also be ended or modified by mutual consent. Discharge by mutual agreement is recognised under Section 62 of the Indian Contract Act, 1872, which states:

“If the parties to a contract agree to substitute a new contract for it, or to rescind or alter it, the original contract need not be performed.”

Termination by mutual agreement may occur in several ways:

• Novation
• Alteration
• Remission
• Rescission
• Waiver
• Merger
• Accord and satisfaction is an English law concept; in India, Section 63 governs remission and acceptance of lesser satisfaction.

Novation (Section 62)

Novation occurs when a new contract is substituted for an existing contract. The new contract may be between:

• the same parties, or
• different parties (by introducing a third party).

The consideration for the new contract is the discharge of the old contract.

Essentials of Novation

Novation has key requirements:

1. There must be a valid and enforceable new substituted contract.
2. Consent of all parties is necessary.
3. Novation should take place before breach or expiry of the old contract.

Case Study: Manohur Koyal v. Thakur Das (1888)

In Manohur Koyal v. Thakur Das (1888), the defendant failed to pay the agreed sum to the plaintiff on the due date stated in the original contract. Later, the defendant promised to pay Rs. 400 and execute a fresh bond (kistibundi bond), and the plaintiff agreed. The defendant then failed to pay this amount as well, and the plaintiff sued.

The Calcutta High Court held that since the new bond was created after breach of the original contract, the contract could not be discharged by novation. The situation was treated as discharge by breach of contract, not novation.

This case highlights a critical point: novation is meant to substitute obligations while the contract is still alive, not after it has already been broken.

Alteration

Alteration means change in one or more terms of a contract by mutual agreement of the parties. When the alteration is material, the old contract is discharged and the altered contract operates.

Alteration requires:

• consent of all parties to the contract, and
• a clear change in terms.

The distinction between novation and alteration:

• In alteration, parties remain the same; only terms change.
• In novation, there may be change of parties, and the old contract is replaced by a new one.

Case Study: United India Insurance Co. Ltd v. M.K.J. Corporation (1996)

In United India Insurance Co. Ltd v. M.K.J. Corporation (1996), the Supreme Court observed that utmost good faith must be observed by contracting parties, and the duty of good faith is of a continuing nature even after completion of the agreement. The Court held that no material alterations can be made to the contract without mutual consent of the parties.

This supports the principle that unilateral changes to contract terms, especially material ones, cannot be treated as valid alteration and may affect enforceability.

Remission (Section 63)

Remission means acceptance of a lesser amount or a lesser degree of performance than what was contracted for, in full discharge of the contract.

This is governed by Section 63 of the Indian Contract Act, 1872, which provides that the promisee may:

• dispense with or remit performance wholly or in part, or
• extend the time for performance, or
• accept any other satisfaction instead of performance.

An important feature is that for such release or promise, there is no need for consideration or a new agreement.

Illustration provided: where a creditor accepts a smaller sum in full satisfaction of the whole debt, the old debt is discharged.

Case Study: Gopala v. Venkata

In Gopala v. Venkata, it was stated that after remission has been communicated to the promisor and accepted by him, the promisee cannot claim the remitted amount. This reinforces the binding nature of remission once it is accepted.

The Indian position under Section 63 is therefore more flexible than the English rule requiring consideration for part-payment settlement.

Accord and Satisfaction (English Law Contrast)

The Accord and Satisfaction under English law means:

• “Accord” is the promise to accept less than what is due, and
• “Satisfaction” is the actual fulfilment of that smaller obligation.

In England, remission generally requires fresh consideration. However, it is clarified that this doctrine has no place in India in the same manner, because Section 63 permits acceptance of lesser amount in full satisfaction without consideration.

This point is useful for comparative understanding, but the operative Indian rule remains Section 63.

Rescission

Rescission occurs when the parties agree to dissolve or cancel the contract. In rescission:

• the old contract is cancelled, and
• no new contract comes into existence in its place.

The parties step out of the contractual relationship by mutual agreement and are released from their obligations.

Waiver

Waiver means abandonment of a right. A party may relinquish rights under the contract, and as a result, the other party is released from corresponding obligations.

An example is waiver of a farmer’s loan by a bank. The waiver discharges the debtor from liability to the extent waived.

Merger

Merger occurs when a superior right and an inferior right coincide in the same person in respect of the same subject matter, and the inferior right vanishes into the superior right.

Illustrations given include:

• a lessee buying the property and becoming the owner, causing lease rights to merge into ownership, and
• a part-time employment arrangement turning into full-time employment, resulting in a change in the basis of rights.

Merger discharges the earlier contract conferring the inferior right.

Discharge by Lapse of Time

A contract may be discharged when the time limit for enforcing contractual rights has expired. If the promisee fails to take legal action within the period prescribed under the Limitation Act, 1963, the remedy becomes barred, and the contract becomes unenforceable through courts.

Contracts may be terminated by lapse of time because civil suits for enforcement are barred by limitation.

A practical implication is that even if a party has a valid claim in substance, failure to institute proceedings within limitation can prevent enforcement.

Discharge by Operation of Law

A contract may terminate by operation of law due to certain legal events that affect rights and liabilities. It includes:

• death,
• insolvency,
• merger,
• lapse of time, and
• unauthorised material alteration.

Death

In contracts involving personal skill or ability, death terminates the contract because performance is dependent on the personal qualifications of the deceased. In other contracts, rights and liabilities may pass to legal representatives.

Insolvency

When a person is adjudged insolvent, the person is discharged from liabilities incurred prior to adjudication. The rights and liabilities of the insolvent, with certain exceptions, pass to an officer of the court such as the Official Assignee or Receiver.

Unauthorised Material Alteration

If the terms of a contract are materially altered without the consent of the other party, the contract is discharged and cannot be enforced. This links back to the principle that material alterations require mutual consent, consistent with the discussion under alteration.

Discharge by Supervening Impossibility and Doctrine of Frustration (Section 56)

Section 56 of the Indian Contract Act deals with impossibility and frustration. It is divided into:

• pre-contractual impossibility, and
• post-contractual (supervening) impossibility.

Pre-contractual Impossibility (Section 56(1))

An agreement to do an act impossible in itself is void ab initio. There are three situations:

1. Impossibility known to both parties: agreement is void from the beginning.
2. Impossibility unknown to both parties: agreement is void due to mutual mistake.
3. Impossibility known only to promisor: the promisor must compensate the promisee for loss sustained due to non-performance (Section 56(3)).

Illustrations provided include promises to ride a horse to the sun, or to discover treasure by magic, which are void agreements.

Post-contractual Impossibility (Section 56, para 2)

A contract that was possible at the time it was made may subsequently become impossible or unlawful due to events beyond the control of parties. Section 56 provides that such a contract becomes void when performance becomes impossible or unlawful.

This is known as supervening impossibility and is also described as the doctrine of frustration. Frustration applies where subsequent events upset the foundation of the bargain, making performance impossible or depriving it of its purpose.

Grounds of Frustration / Supervening Impossibility

Several situations for grounds of frustration / supervening impossibility include:

• destruction of subject matter of contract,
• change of law making performance unlawful,
• failure of pre-conditions or change in the state of things,
• death or incapacity for personal services, and
• outbreak of war (with rules on contracts with alien enemies and suspension of pre-war contracts).

Case Study: Satyabrata Ghosh v. Mugneeram Bangur (AIR 1954 SC 44)

In Satyabrata Ghosh v. Mugneeram Bangur (AIR 1954 SC 44), the Supreme Court examined frustration and clarified important principles:

• The doctrine of frustration comes into play when a contract becomes impossible of performance after it is made due to circumstances beyond control of parties.
• It falls within the purview of Section 56 of the Indian Contract Act.
• The word “impossible” is not limited to physical or literal impossibility.
• Performance may not be literally impossible but may become impracticable and useless from the point of view of the object and purpose of the parties.
• If an untoward event totally upsets the foundation of the bargain, it can be treated as impossibility under Section 56.

The effect of frustration is that it automatically discharges the contract from the date of the frustrating event.

Exceptions: When the Contract is Not Discharged Despite Difficulty

Impossibility is not an excuse in all circumstances. Frustration does not apply in certain cases:

1. Difficulty of performance does not excuse performance.
   • Case cited: Tsakiroglou & Co v. Noblee Thori (1962) AC 93.
   • The closure of the Suez Canal caused transportation problems, but unless use of that route was an express or implied term, it did not make performance impossible.
2. Commercial impossibility does not discharge the contract.
   • Increased cost, lack of profits, wage increases, or raw material cost increases do not excuse performance unless contract provides otherwise.
3. Strikes, lock-outs, civil disturbances and riots do not discharge contracts unless there is a contractual clause providing for termination or extension in such events.
4. Failure of one object does not discharge the contract if there were several purposes.

These exceptions show that the law maintains contractual certainty. Mere hardship or inconvenience is not enough; the change must strike at the foundation of the contract.

Discharge by Breach of Contract

A contract is discharged by breach when a party refuses to perform, fails to perform, disables performance, or makes performance impossible by conduct. When one party commits breach, the other party may treat the contract as discharged and pursue remedies.

Breach may be:

• actual breach, or
• anticipatory breach.

Actual Breach

Actual breach occurs when, at the time performance is due, one party fails or refuses to perform obligations. Refusal may be express or implied by conduct or non-action.

Illustration provided: agreement to deliver goods on a particular date and failure to deliver amounts to breach.

Anticipatory Breach (Section 39)

Anticipatory breach occurs when a party:

• announces before the time for performance that the contract will not be performed, or
• disables performance by own act before the due date.

Illustrations provided include refusal to supply goods before delivery date, and a promise to marry followed by marriage to another person.

Consequences of Anticipatory Breach

Two choices available to the aggrieved party in  cases of anticipatory breach:

1. Treat the contract as discharged and immediately take legal action for remedies such as damages, specific performance or injunction; or
2. Not treat the contract as discharged, keep it alive, and wait for performance.

If the aggrieved party keeps the contract alive and subsequently a legal event occurs that discharges the contract (for example, supervening impossibility), the right to sue for damages may be lost. An illustration is provided where nationalisation of an industry later discharged the contract, leaving no remedy against the party who earlier refused.

Remedies for Breach of Contract

Where discharge occurs due to breach, remedies become significant. The several remedies for breach of contract include:

Rescission of Contract (Section 75)

When there is breach by one party, the other party may rescind the contract and need not perform obligations. Section 75 provides that a person who rightfully rescinds a contract is entitled to compensation for damages sustained through non-fulfilment.

Suit for Damages (Section 73)

Damages are monetary compensation awarded to the aggrieved party for loss or injury suffered due to breach.

The foundation of the modern law of damages is Hadley v. Baxendale (1854) 9 E. 341, which is incorporated in Section 73.

Case Study: Hadley v. Baxendale (1854)

In Hadley v. Baxendale, the plaintiff’s mill stopped due to a broken crankshaft. The shaft was given to a carrier for delivery to manufacturers as a pattern. Delay occurred due to the carrier’s neglect. The plaintiff claimed compensation for wages and depreciation during idleness and for loss of profits. The first two were allowed as natural consequences; loss of profits was disallowed as remote.

This case supports Section 73 principles: compensation is for loss arising naturally in the usual course, or loss that parties knew was likely, but not for remote or indirect losses.

• damages are compensatory, not punitive,
• if there is no loss, damages cannot be claimed,
• duty to minimise loss exists, and
• special damages require knowledge of special circumstances.

Liquidated Damages and Penalty (Section 74)

Section 74 deals with predetermined sums payable on breach. It is clarified that Indian law does not recognise the strict English distinction between liquidated damages and penalty; courts award reasonable compensation not exceeding the amount named.

Case referred: Mackintosh v. Crow (1883) 9 Cal 689, relating to enhanced interest rates being treated as penalty if exorbitant.

Earnest Money and Security Deposit

In Shree Hanuman Cotton Mills v. Tata Aircraft Ltd. [1969] 3 SCC 522, the court held that earnest money may be forfeited on breach if it is a reasonable amount.

Specific Performance

Specific performance is an order directing a party to fulfil contractual obligations, granted when damages are not adequate. It is linked with the Specific Relief Act and the specific performance is discretionary and not granted in personal contracts or where court supervision is impracticable.

Injunction

Injunction restrains breach of negative terms. The case cited is Warner Bros. v. Nelson, where a film actress who agreed to act exclusively for a company could be restrained from acting for another during the contract period. Specific performance was not ordered because it involved personal service.

Quantum Meruit

Quantum meruit means payment in proportion to work done. It is quasi-contractual, arising after discharge of the original contract.

Cases cited:

• Planche v. Colburn: part performance in instalment publication context, with contract ending before completion; claim allowed.
• Craven Ellis v. Canons Ltd. [1936] 2 K.B. 403: appointment found void; services rendered allowed recovery on quantum meruit.
• Cutter v. Powell: indivisible contract requiring complete performance; payment not recoverable when performance not completed.

There are also situations where divisible contracts may allow payment for part performed if the other party has enjoyed benefit, but indivisible contracts generally do not.

Conclusion

Discharge of contract under the Indian Contract Act, 1872 is a core concept because it determines when contractual obligations come to an end and what consequences follow. Discharge may occur through performance (actual or tender), mutual agreement (novation, alteration, remission, rescission, waiver, merger), lapse of time, operation of law, supervening impossibility under Section 56, or breach of contract (including anticipatory breach under Section 39).
