Impossibility of Performance under Section 56 of the Indian Contract Act, 1872

Understand initial and supervening impossibility of performance, Section 56, the doctrine of frustration, landmark judgments, and important exam principles under Indian contract law.

Introduction

The performance of a contract is a fundamental principle of contract law. Once parties enter into a valid agreement, they are generally expected to fulfil their respective promises. However, circumstances may arise in which performance is impossible from the beginning or becomes impossible after the contract has been formed.

The Indian Contract Act, 1872, addresses these situations through Section 56, which deals with agreements to do impossible acts and contracts that subsequently become impossible or unlawful to perform.

Impossibility of performance refers to a situation in which a contractual obligation cannot legally or practically be performed in the manner contemplated by the law. Depending on the circumstances, the agreement may be void from the beginning or a previously valid contract may become void when performance becomes impossible or unlawful.

The law does not, however, excuse a party merely because performance has become expensive, inconvenient, or commercially disadvantageous. Courts examine the nature of the obligation, the event causing the impossibility, the contractual terms, and the legal consequences of the event.

Meaning of Impossibility of Performance

Impossibility of performance arises when an act promised under an agreement cannot be performed in the legally relevant sense.

There are two principal forms:

1. Initial impossibility: The act is impossible in itself when the agreement is made.
2. Supervening impossibility: A contract that was initially capable of performance subsequently becomes impossible or unlawful because of a qualifying event.

The distinction is important because initial impossibility is addressed by the first part of Section 56, whereas supervening impossibility is addressed by its second part.

Example of Initial Impossibility

A agrees to bring a person back to life in exchange for ₹1,00,000. The promised act is inherently impossible. The agreement is void under Section 56.

Example of Supervening Impossibility

A agrees to rent a specific auditorium to B for a concert. Before the concert takes place, the auditorium is destroyed by an accidental fire. If the contract does not provide an applicable alternative and the destruction makes the agreed performance impossible, the contract may become void under Section 56.

Section 56 of the Indian Contract Act, 1872

Section 56 is the principal statutory provision governing impossibility of performance in India. It covers three distinct situations.

1. Initial Impossibility

The first part of Section 56 provides that an agreement to do an act impossible in itself is void.

The impossibility exists when the agreement is made. The parties cannot create an enforceable obligation to perform an act that is inherently impossible.

Example: A agrees to produce gold from ordinary water through a process that cannot achieve the promised result. The agreement is void if the promised act is impossible in itself.

Initial impossibility should be distinguished from a contract that becomes impossible only after its formation.

2. Supervening Impossibility or Illegality

The second part of Section 56 provides that a contract to do an act that becomes impossible, or becomes unlawful because of an event the promisor could not prevent, becomes void when the act becomes impossible or unlawful.

This is the statutory foundation of the doctrine of frustration under Indian law.

The essential requirements include:

• A valid contract existed when it was made.
• Some contractual performance remained outstanding.
• A subsequent event occurred.
• The event made the relevant performance impossible or unlawful in the legally recognised sense.
• The impossibility was not simply a difficulty or risk that the party had undertaken to bear.

Example: A agrees to supply a product to B. Before the agreed delivery date, a valid legal prohibition makes the agreed supply unlawful. If no lawful alternative performance is available under the contract, the contract may become void under Section 56.

The effect of a subsequent event depends on the actual contractual obligation. A temporary restriction, increased cost, or administrative delay will not necessarily make performance impossible.

3. Compensation for Knowledge of Initial Impossibility or Illegality

The third part of Section 56 addresses a situation in which a person promises to perform an act that the person knew, or could have known through reasonable diligence, was impossible or unlawful, while the promisee did not know this.

In such circumstances, the promisor must compensate the promisee for the loss sustained through non-performance.

Example: A promises B that A will perform a particular act. A knows that the act is legally prohibited, but B does not know this. If the statutory conditions are satisfied, A may be liable to compensate B for the resulting loss.

This provision differs from ordinary supervening impossibility. It concerns the promisor’s knowledge of the impossibility or illegality at the time of the promise.

Types of Impossibility of Performance

1. Physical Impossibility

Physical impossibility arises when the agreed act cannot physically be carried out because of the circumstances.

For example, A agrees to supply a specifically identified machine to B. Before delivery, the machine is accidentally destroyed, and no contractual alternative or substitute can satisfy the obligation.

The destruction may make performance impossible if the continued existence of that particular machine was essential to the agreement.

However, the destruction of one item does not automatically frustrate every contract involving similar goods. If the agreement allows substitute goods or performance remains possible, the legal result may be different.

2. Legal Impossibility

Legal impossibility arises when a change in law or another legally effective prohibition makes the promised performance unlawful.

For example, A agrees to supply a particular item to B. Before delivery, legislation prohibits the agreed transaction. If the prohibition applies to the contract and no lawful alternative remains, Section 56 may apply.

A party cannot insist on performance that has become unlawful merely because the contract was valid when originally made.

3. Commercial Difficulty and Increased Cost

A contract does not ordinarily become impossible merely because performance is more expensive or less profitable than anticipated.

For example, A agrees to supply goods to B at a fixed price. The market price of the goods subsequently increases significantly. A generally remains bound by the agreed price because increased cost alone does not establish impossibility under Section 56.

In Alopi Parshad & Sons Ltd. v. Union of India, AIR 1960 SC 588, the Supreme Court rejected the proposition that increased expense and changed economic circumstances automatically entitled a party to relief from its contractual obligations.

The principle is that courts do not ordinarily rewrite a contract simply because the agreed bargain has become commercially disadvantageous.

4. Impossibility Arising from Destruction of an Essential Subject Matter

Where a contract depends on the continued existence of a specific property, venue, or object, its destruction may prevent the agreed performance.

For example, A hires a particular hall from B for a scheduled performance. If the hall is destroyed before the event, and the contract depends on that specific venue, performance may become impossible.

The outcome depends on whether the continued existence of the subject matter was essential and whether the contract provides for an alternative.

5. Impossibility Arising from Failure of an Essential Event

Some contracts are based on the occurrence of a particular event. If the event does not occur, the foundation of the agreement may be destroyed.

In Krell v. Henry [1903] 2 KB 740, a room was hired for viewing a coronation procession that was subsequently cancelled. The court treated the contract as frustrated because the procession formed the foundation of the agreement.

This English decision illustrates the historical development of the doctrine. In India, the governing legal framework remains Section 56 and the applicable Indian authorities.

Important Case Laws on Impossibility of Performance

1. Satyabrata Ghose v. Mugneeram Bangur & Co.

Citation: AIR 1954 SC 44; (1954) 2 SCR 310.

Facts: The dispute concerned an agreement connected with the development and sale of plots of land. Government requisition of land affected the development scheme, and the question arose whether the circumstances had made the contractual performance impossible.

Issue: Whether Section 56 applies only to literal physical impossibility and whether the government requisition frustrated the contract.

Judgment: The Supreme Court held that Section 56 governs the doctrine of frustration in India. Impossibility is not limited to literal physical impossibility. An event that fundamentally upsets the basis of an agreement may make performance impossible in the relevant legal sense. However, the requisition in the case did not establish frustration because performance had not become impossible in the manner required by the provision.

Legal principle: Courts must assess the practical effect of the event on the contractual obligation. Mere inconvenience or a change in circumstances does not automatically discharge a contract.

Significance: This is the leading Indian authority on impossibility of performance and frustration under Section 56. <Cite refs={[“turn454102search1″,”turn454102search5”]} />

2. Alopi Parshad & Sons Ltd. v. Union of India

Citation: AIR 1960 SC 588; (1960) 2 SCR 793.

Facts: The dispute arose from a contractual arrangement for supplying provisions to the government during the Second World War. The claimants sought additional remuneration because changed circumstances had increased their costs.

Issue: Whether increased expense and changed economic circumstances justified relief from the contractual terms.

Judgment: The Supreme Court rejected the claim based merely on increased costs and changed circumstances.

Legal principle: A contract is not frustrated simply because performance becomes more expensive or less profitable. Commercial hardship does not, by itself, establish impossibility under Section 56.

Significance: The decision is important for distinguishing genuine impossibility from an unfavourable commercial bargain.

3. Energy Watchdog v. Central Electricity Regulatory Commission

Citation: (2017) 14 SCC 80.

Facts: Power producers sought relief under force majeure principles after an increase in the price of imported coal affected the economics of their power purchase agreements.

Issue: Whether the increase in coal prices frustrated the agreements under Section 56 or justified relief under the contractual force majeure provisions.

Judgment: The Supreme Court rejected the argument that the increased cost of coal, by itself, frustrated the contracts. The Court also considered the distinction between Section 32, which concerns contractual provisions addressing contingent events, and Section 56, which governs impossibility or illegality.

Legal principle: A contract does not become impossible merely because it has become more onerous. Where the contract addresses the relevant event, the force majeure clause must be interpreted according to its terms.

Significance: The decision is a leading authority on impossibility of performance, frustration, and force majeure under Indian contract law.

4. Naihati Jute Mills Ltd. v. Khyaliram Jagannath

Citation: AIR 1968 SC 522; (1968) 1 SCR 821.

Facts: The dispute concerned a commercial contract affected by difficulties relating to import and the circumstances surrounding performance.

Issue: Whether the difficulties relied upon by a party were sufficient to discharge the contract under the doctrine of frustration.

Legal principle: A party is not automatically excused because performance becomes difficult. The terms of the contract, the allocation of risk, and the effect of the intervening circumstances must be examined.

Significance: The case reinforces the distinction between impossibility of performance and ordinary contractual difficulty.

5. Taylor v. Caldwell

Citation: (1863) 3 B & S 826.

Facts: A music hall was hired for scheduled performances but was destroyed by an accidental fire before the performances took place.

Issue: Whether the parties remained bound when the specific venue essential to performance no longer existed.

Judgment: The court held that the parties were excused from performance because the continued existence of the hall was fundamental to the agreement.

Legal principle: Destruction of an essential subject matter may discharge a contract where continued existence is necessary for performance.

Significance: This is a foundational English decision explaining the historical development of impossibility and frustration. It is illustrative rather than a substitute for the Indian statutory framework.

Difference Between Initial and Supervening Impossibility

Basis	Initial impossibility	Supervening impossibility
Meaning	The act is impossible when the agreement is made.	Performance becomes impossible or unlawful after the contract is made.
Relevant provision	First part of Section 56	Second part of Section 56
Legal effect	The agreement is void from the beginning.	The contract becomes void when the relevant impossibility or illegality arises.
Example	An agreement to perform an inherently impossible act.	Destruction of a specific venue essential to an agreement.
Key question	Was the promised act impossible from the outset?	Did a subsequent event make the outstanding performance impossible or unlawful?

Difference Between Impossibility of Performance and Frustration of Contract

The expressions are closely related in Indian contract law, but their use depends on the context.

Basis	Impossibility of performance	Frustration of contract
Scope	Includes initial impossibility and supervening impossibility or illegality.	Commonly refers to a contract becoming impossible or unlawful after formation.
Statutory basis	Section 56	Principally the second part of Section 56
Timing	May exist from the beginning or arise later.	Arises from a subsequent event.
Legal effect	Depends on whether the impossibility is initial or supervening.	A qualifying supervening event makes the contract void.
Example	An agreement to perform an inherently impossible act.	A contract affected by destruction of its essential subject matter.

Difference Between Section 32 and Section 56

Section 32 and Section 56 must not be treated as interchangeable provisions.

Section 32 concerns contingent contracts and may govern a contractual force majeure clause that specifies what happens if a particular event occurs.

Section 56 addresses initial impossibility and contracts that subsequently become impossible or unlawful to perform in the statutory sense.

Basis	Section 32	Section 56
Subject	Contingent contracts and contractual conditions	Initial and supervening impossibility or illegality
Role of contract terms	The terms defining the contingency are central.	Relevant, including whether the contract allocates the risk.
Common application	A force majeure clause dealing with specified events	A supervening event that makes performance impossible or unlawful outside a controlling contractual provision
Example	A contract expressly provides for suspension following a specified event.	A subsequent legal prohibition makes the agreed performance unlawful.

In Energy Watchdog v. Central Electricity Regulatory Commission, the Supreme Court emphasised the importance of examining the contractual provisions before relying on frustration under Section 56.

Legal Consequences of Impossibility of Performance

1. The Agreement or Contract Becomes Void

Where an agreement is impossible in itself, it is void under the first part of Section 56. Where a previously valid contract becomes impossible or unlawful under the second part, it becomes void when the relevant event occurs.

2. Future Performance Is Discharged

When a contract is frustrated, the parties are generally excused from future performance of the obligations discharged by the event.

Frustration is distinct from breach because the contract becomes void by operation of law when the statutory requirements are met. It does not ordinarily depend on the innocent party electing to terminate the contract.

3. Restoration of Benefits Under Section 65

Section 65 of the Indian Contract Act, 1872, addresses the obligation to restore advantages received under an agreement that is discovered to be void or a contract that becomes void.

Where Section 65 applies, a party that has received an advantage may be required to restore it or make compensation for it.

Example: A pays B an advance for a contractual performance that subsequently becomes impossible under circumstances attracting Section 56. Whether the advance must be returned must be considered under Section 65 and the applicable legal rules.

4. Compensation in Cases Covered by the Third Part of Section 56

Where the promisor knew, or could have known through reasonable diligence, that the promised act was impossible or unlawful, while the promisee did not know this, the third part of Section 56 may require compensation for the loss caused by non-performance.

This is a specific statutory rule and should be distinguished from the ordinary consequences of supervening impossibility.

5. Damages Are Not Automatic

A party is not automatically liable for breach-of-contract damages merely because performance has become impossible under Section 56. However, liability may arise where the facts disclose a separate breach or a statutory basis for compensation.

The legal outcome depends on the cause of impossibility, the terms of the contract, and the applicable statutory provisions.

Exceptions and Limitations

The doctrine of impossibility has important limitations.

Increased Cost or Reduced Profit

A rise in prices, currency fluctuations, or reduced profitability does not ordinarily make a contract impossible to perform.

Mere Delay

Delay does not automatically frustrate a contract. Its effect depends on the nature of the obligation, the duration and consequences of the delay, and whether timely performance was fundamental to the agreement.

Self-Induced Impossibility

A party cannot ordinarily rely on impossibility created by its own breach, negligence, or voluntary conduct to escape contractual obligations.

Contractual Allocation of Risk

Where a contract expressly addresses the event, the clause must be interpreted to determine the parties’ rights and obligations. Section 32 may be relevant where the contract contains a force majeure provision.

Availability of Alternative Performance

If the contract can still be performed through an alternative permitted by its terms, the loss of the original method may not establish impossibility.

Failure to Establish a Fundamental Change

An unexpected event is not enough by itself. The party relying on Section 56 must establish that the event has made the relevant contractual performance impossible or unlawful in the required legal sense.

Key Points for Exams

1. Section 56 of the Indian Contract Act, 1872, is the principal provision governing impossibility of performance.
2. Initial impossibility exists when the agreement is made and makes the agreement void.
3. Supervening impossibility arises when a subsequent event makes performance impossible or unlawful, causing the contract to become void.
4. Impossibility is not restricted to literal physical impossibility, as explained in Satyabrata Ghose v. Mugneeram Bangur & Co.
5. Increased cost or commercial hardship alone does not ordinarily frustrate a contract, as explained in Alopi Parshad & Sons Ltd. v. Union of India and Energy Watchdog v. CERC.
6. Section 32 may govern a contractual force majeure clause, while Section 56 addresses statutory impossibility and frustration.
7. Section 65 may require restoration of advantages received under a contract that becomes void, where its requirements are satisfied.
8. The third part of Section 56 provides for compensation in the specified circumstances involving the promisor’s knowledge of initial impossibility or illegality.
9. Frustration operates by law when the requirements of Section 56 are satisfied; it is not simply a form of breach.
10. The terms of the contract, the cause of impossibility, and the legal effect of the event must be examined in each case.

Conclusion

Impossibility of performance is an important principle of Indian contract law because it determines when contractual obligations cannot be enforced due to the nature of the promised act or a subsequent event. Section 56 distinguishes agreements that are impossible from the beginning from contracts that become impossible or unlawful after formation.

The Supreme Court’s decisions in Satyabrata Ghose, Alopi Parshad, and Energy Watchdog establish the central principles: impossibility is not confined to literal physical impossibility, commercial hardship alone is insufficient, and contractual force majeure provisions must be examined according to their terms.

For law students, the most important task is to identify whether the impossibility existed at the time of agreement or arose later, and then apply the relevant part of Section 56 to determine the legal consequences.
