Exercise — Chapter 3A: Law of Contract (Remedies in Case of Breach)

1Ramesh sells his bike to his friend Suresh for a consideration of Rs. 50,000/-, whereas the market price of the said bike is Rs. 65,000/-. Examine if the agreement is enforceable under Law of Contract.Show solution
Given:
- Ramesh sells his bike to Suresh for Rs. 50,000/-.
- The market price of the bike is Rs. 65,000/-.
- The transaction is between friends.

Concept/Legal Provision:
Under the Indian Contract Act, 1872 (ICA), Section 2(d) defines consideration as something done, abstained from, or promised at the desire of the promisor. Section 25 of the ICA states that an agreement without consideration is void. However, the law does not require consideration to be adequate — it only requires that consideration must be real and of some value in the eyes of law.

Further, Section 10 of the ICA lays down the essentials of a valid contract:
1. Free consent of parties
2. Competency of parties
3. Lawful consideration
4. Lawful object
5. Not expressly declared void

Analysis:
- The consideration here is Rs. 50,000/-, which is a real and tangible amount of money. The law does not mandate that consideration must be equal to the market value of the subject matter.
- The fact that the bike's market price is Rs. 65,000/- does not make the consideration inadequate in the legal sense, as long as both parties have freely consented to the price of Rs. 50,000/-.
- There is no indication of coercion, undue influence, fraud, or misrepresentation.
- Both parties appear to be competent to contract.
- The object (sale of a bike) is lawful.

Conclusion:
The agreement between Ramesh and Suresh is valid and enforceable under the Law of Contract. Inadequacy of consideration alone does not make a contract void, provided the consent was freely given. As held in various judicial interpretations of the ICA, courts will not question the adequacy of consideration so long as it exists and consent is free.
2'D', a minor borrowed a sum of money from M by executing a mortgage of his property in favour of M. Subsequently, D sued for cancellation of mortgage. Is the contract of mortgage valid? Can M recover the sum advanced to D?Show solution
Given:
- D is a minor.
- D borrowed money from M and executed a mortgage of his property in favour of M.
- D subsequently sued for cancellation of the mortgage.

Concept/Legal Provision:
Under Section 11 of the Indian Contract Act, 1872, every person is competent to contract who:
1. Has attained the age of majority (18 years as per the Indian Majority Act, 1875),
2. Is of sound mind, and
3. Is not disqualified from contracting by any law.

A minor is not competent to contract. Any agreement entered into by a minor is void ab initio (void from the very beginning). This was firmly established in the landmark case of Mohori Bibee v. Dharmodas Ghose (1903), where the Privy Council held that a mortgage executed by a minor is void and cannot be enforced.

Analysis:

(i) Validity of the Mortgage Contract:
- Since D is a minor, he lacks the legal capacity to enter into a contract.
- The mortgage executed by D in favour of M is therefore void ab initio.
- D's suit for cancellation of the mortgage will succeed, as the contract was never legally valid.

(ii) Recovery of Money by M:
- Since the contract is void, M cannot sue D for recovery of the loan amount on the basis of the contract.
- A minor's agreement being void means no obligations arise from it — neither can the minor be asked to repay the money nor can the mortgage be enforced.
- However, under Section 65 of the ICA (restitution), if a person received any advantage under a void agreement, they must restore it. But courts have generally held that Section 65 does not apply to minors because a minor was never competent to contract in the first place.
- M may, in some circumstances, seek relief under the doctrine of restitution in equity (not under contract law), but this is limited and uncertain.

Conclusion:
- The contract of mortgage is not valid — it is void ab initio.
- D's suit for cancellation of the mortgage will succeed.
- M cannot recover the sum advanced to D through contractual remedies, as the law does not allow enforcement of a contract against a minor. M bears the loss due to his own negligence in lending money to a minor.
3Apexx Chemicals entered into an agreement with Moonled Pharma Ltd. to supply them with 16 units calcium and 8 units of magnesium powder for its medicine unit. By the time Apexx Chemicals supplied 12 units of calcium and 4 units of magnesium the government restricted free sale of chemicals for life saving drugs. Every dealer was supposed to get his supply sanctioned from the government to a maximum of 10 units of each chemical. Apexx Chemicals found it difficult to complete the order of Moonled Pharma Ltd. Moonled Pharma Ltd. brings a suit for breach of contract against Apexx Chemicals. Will it succeed? Analyze by referring to relevant provisions.Show solution
Given:
- Apexx Chemicals agreed to supply 16 units of calcium and 8 units of magnesium to Moonled Pharma Ltd.
- Apexx supplied 12 units of calcium and 4 units of magnesium before the government imposed restrictions.
- The government restricted free sale and capped supply at a maximum of 10 units of each chemical per dealer.
- Moonled Pharma Ltd. sues Apexx Chemicals for breach of contract.

*(Note: The question mentions 'Adarsh Chemicals' in the suit — this appears to be a typographical error in the source; the analysis applies to Apexx Chemicals.)*

Concept/Legal Provision:
This question involves the doctrine of Supervening Impossibility or Frustration of Contract under Section 56 of the Indian Contract Act, 1872.

Section 56 states:
> *"A contract to do an act which, after the contract is made, becomes impossible, or, by reason of some event which the promisor could not prevent, unlawful, becomes void when the act becomes impossible or unlawful."*

This is also known as the doctrine of 'Frustration of Contract'. When performance of a contract becomes impossible or illegal due to a subsequent change in law or government action, the contract is discharged and neither party is liable for breach.

Analysis:

| Aspect | Detail |
|---|---|
| Original obligation | Supply 16 units Ca + 8 units Mg |
| Already supplied | 12 units Ca + 4 units Mg |
| Remaining obligation | 4 units Ca + 4 units Mg |
| Government cap | Maximum 10 units per chemical |

- At the time of contracting, the agreement was perfectly legal and possible.
- After partial performance, the government imposed a restriction making it unlawful to supply chemicals beyond 10 units without government sanction.
- Apexx Chemicals had already supplied 12 units of calcium (which exceeded the new cap of 10 units — this was done before the restriction came into force).
- After the restriction, supplying the remaining 4 units of calcium would require government sanction, and the cap of 10 units had already been crossed.
- The remaining supply became impossible/unlawful due to a supervening government order — an event beyond Apexx Chemicals' control.
- This is a classic case of supervening illegality under Section 56 ICA.

Conclusion:
- The contract, to the extent of the remaining unperformed portion, stands discharged by frustration under Section 56 of the ICA.
- Apexx Chemicals is not liable for breach of contract for the portion that became impossible/unlawful to perform due to the government restriction.
- The suit by Moonled Pharma Ltd. for breach of contract will not succeed for the unperformed portion, as the non-performance was caused by a supervening impossibility/illegality beyond Apexx Chemicals' control.
- However, Moonled Pharma Ltd. may be entitled to a refund of any advance paid for the undelivered portion under Section 65 of the ICA (restitution upon void agreement).
4X enters into a contract with Y to pay him 10,000 rupees if the books are delivered to him by Friday. This is an example of contingent contract. Explain why?Show solution
Given:
- X contracts with Y to pay Rs. 10,000/- if the books are delivered to X by Friday.

Concept/Legal Provision:
A Contingent Contract is defined under Section 31 of the Indian Contract Act, 1872 as:
> *"A contingent contract is a contract to do or not to do something, if some event, collateral to such contract, does or does not happen."*

The essential features of a contingent contract are:
1. Conditional performance — the performance depends upon the happening or non-happening of a future event.
2. The event must be uncertain — it may or may not happen.
3. The event must be collateral — it must be incidental/collateral to the contract, not the main subject matter itself.
4. The event must be future — it should not have already occurred.

Contingent contracts are governed by Sections 31–36 of the ICA.

Explanation of why this is a Contingent Contract:

| Feature | Application to the given contract |
|---|---|
| Conditional performance | X will pay Rs. 10,000/- only if books are delivered by Friday |
| Uncertain future event | It is uncertain whether Y will deliver the books by Friday or not |
| Collateral event | Delivery of books by Friday is an event collateral to the payment obligation |
| Future event | The delivery is yet to happen (by Friday) |

- The obligation of X to pay Rs. 10,000/- is not absolute — it is contingent upon the happening of a specific event, i.e., delivery of books by Friday.
- If Y delivers the books by Friday → the condition is fulfilled → X must pay Rs. 10,000/-.
- If Y does not deliver the books by Friday → the condition is not fulfilled → X is not obligated to pay.
- The event (delivery by Friday) is collateral to the main contract and is uncertain in nature.

Conclusion:
This contract is a contingent contract under Section 31 of the ICA because X's obligation to pay Rs. 10,000/- depends entirely on the happening of a future and uncertain event — the delivery of books by Friday. The payment is not unconditional but is tied to the fulfilment of a collateral condition, which is the hallmark of a contingent contract.
