1) Meaning of Consent (Consensus ad idem) #
Consent means that both parties agree upon the same thing in the same sense.
This is traditionally called consensus ad idem (meeting of minds).
- It is not just a verbal “yes”.
- It is a real meeting of minds on the same subject matter, same terms, and same understanding.
Example: If A thinks he is buying House No. 10, but B thinks he is selling House No. 11, there is no consensus ad idem, so there is no true consent.
2) Statutory Basis of Consensus ad idem (Section 13, ICA 1872) #
Section 13 – “Consent” #
Two or more persons are said to consent when they agree upon the same thing in the same sense.
So, Section 13 = Consent = consensus ad idem.
3) Meaning of Free Consent (Section 14, ICA 1872) #
Section 14 – “Free Consent” #
Consent is said to be free when it is not caused by:
- Coercion (S.15)
- Undue Influence (S.16)
- Fraud (S.17)
- Misrepresentation (S.18)
- Mistake (Ss.20, 21, 22)
4) What if Free Consent is Absent? #
(A) Voidable Contract (generally) #
When consent is not free due to coercion, undue influence, fraud, misrepresentation → the contract is usually voidable at the option of the aggrieved party (mainly covered under Sections 19 and 19A).
(B) Void Agreement (in cases of certain mistakes) #
When consent is affected by certain mistakes (especially mutual mistake of fact) → the agreement can be void (not enforceable).
i) Coercion (Section 15) #
Meaning #
Coercion means committing or threatening to commit any act forbidden by IPC, or unlawfully detaining or threatening to detain property, with the intention of causing a person to enter into an agreement.
Key features:
- Involves threat/pressure.
- Can be against person or property.
- Purpose: to force consent.
Effect #
Contract is voidable at the option of the party whose consent was obtained by coercion.
Case Law: Chikkam Amiraju v. Chikkam Sheshama #
Facts:
A husband threatened to commit suicide if his wife and son did not execute a sale deed in his brother’s favour. Under this fear, they executed the deed.
Issue:
Whether a threat to commit suicide amounts to coercion under Section 15?
Held:
Yes. Threat of suicide was treated as coercion. The consent was not free, and the contract/deed was voidable.
ii) Undue Influence (Section 16) #
Meaning #
Undue influence happens when:
- One party is in a position to dominate the will of the other, and
- Uses that position to obtain an unfair advantage.
When domination is presumed:
- Fiduciary relationship exists (doctor–patient, solicitor–client, teacher-student, employer-employee)
- One party is clearly having dominance or authority over other
Effect #
Contract is voidable, and court can also set aside or enforce it on fair terms.
Case Law 1: Lloyds Bank v. Bundy #
Facts:
An elderly man (Bundy) mortgaged his house to support his son’s business debts to the bank. He relied heavily on the bank and did not take independent advice.
Issue:
Whether the transaction was the result of undue influence / inequality of bargaining power leading to unfair advantage?
Held:
The court protected Bundy because the bargain was manifestly unfair, and the bank had taken advantage of his reliance. Relief was granted (transaction not enforced in that oppressive form).
Case Law 2: Odorizzi v. Bloomfield School District #
Facts #
Odorizzi was a school teacher. He was arrested, and soon after (while he was exhausted, emotionally shaken, and vulnerable), the principal/superiors visited him and pressured him to resign immediately, threatening embarrassment and consequences. They allegedly used allegations like homosexuality/indecency and urged him to resign then and there, without giving him real time to recover or seek advice.
Issue #
Whether the resignation was truly voluntary, or whether it was obtained by undue influence (unfair persuasion taking advantage of his weakened condition).
Held #
The court treated it as a strong case of undue influence / unfair persuasion:
- Odorizzi was in a weakened mental and physical state,
- the authorities were in a position of dominance/authority,
- and the persuasion was improper and pressurising, causing him to resign without free will.
So, the resignation could be challenged as not being a product of free consent.
iii) Fraud (Section 17) #
Meaning #
Fraud includes, suggesting something as fact knowing it is false, Active concealment, promise made without intention to perform, any act fitted to deceive, any act/omission declared fraudulent by law.
Key element: Intention to deceive.
Effect #
Contract is voidable (and in many situations, damages can be claimed depending on facts).
Case Law: Keates v. The Earl of Cadogan #
Facts: Landlord leased a house to the tenant for immediate occupation. The house was ruinous/unsafe, and the landlord knew it, but said nothing. Later, part of the house collapsed / danger arose.
Issue: Does a landlord commit fraud / actionable misrepresentation merely by not disclosing that the premises are unsafe (i.e., is silence enough)?
Held: No. There is no implied duty to disclose defects merely because the landlord knows them. Silence alone is not fraud/misrepresentation. Tenant can succeed only if there is (i) an express warranty about condition or (ii) active deceit / concealment. (So, effectively: caveat emptor principle.)
iv) Misrepresentation (Section 18) #
Meaning #
Misrepresentation means a false statement made innocently (without intent to deceive), which induces the other party to contract.
Includes:
- Positive assertion not warranted by information (though believed true),
- Breach of duty causing another to be misled (without intent),
- Causing mistake about subject matter innocently.
Effect #
Contract is voidable at the option of the party misled.
Case Law: The Oceanic Steam Navigation Co. Ltd. v. Soonderdas Dhurumsey #
Facts: While making the charter/contract, the ship’s tonnage was described/represented in a particular way. Later, when the ship was checked, the actual tonnage was found to be different from what had been described. The other party refused to proceed.
Issue: Does a wrong statement about the ship’s tonnage amount to misrepresentation, giving the other party a right to avoid the contract?
Held: Yes. The tonnage description was treated as material. Since it turned out to be incorrect and it affected consent, it was misrepresentation (Section 18), making the contract voidable at the option of the misled party (Section 19 consequence).
Brief Note: Difference between Fraud and Misrepresentation #
| Aspect | Fraud (S.17) | Misrepresentation (S.18) |
|---|---|---|
| Intention | Intentional deception | Innocent/without intent |
| Belief | Maker knows it is false | Maker believes it to be true |
| Remedy | Voidable + possible damages | Usually voidable; damages generally not unless special duty/fraud-like situation |
| Moral blame | Higher | Lower |
In short:
Fraud = lie knowingly. Misrepresentation = wrong statement innocently.
v) Mistake (Sections 20, 21, 22) #
(A) Section 20 – Mutual Mistake of Fact (Void) #
Meaning #
Where both parties are under a mistake as to a matter of fact essential to the agreement, the agreement is void.
Case Law: Tara Singh v. Sukhminder Singh (unit confusion) #
Facts:
Parties entered in to contract for sale of land but due to confusion between measurement units (bigha vs kanal), both were mistaken about the actual size of land.
Issue:
Whether a mutual mistake regarding a fundamental fact (area) makes the agreement void?
Held:
Yes. Since both parties were mistaken on an essential fact (area of land), the agreement was treated as void under Section 20.
(B) Section 21 – Mistake of Law (Valid contract, generally) #
Meaning #
Mistake of law is generally no excuse.
So, a contract does not become void/voidable merely because a party misunderstood the law.
Illustration #
A agrees to pay B ₹50,000 as “penalty” because A wrongly believes that law makes it mandatory to pay such penalty for late delivery, when actually the law doesn’t require it.
This is mistake of law → contract generally not void under Section 21.
Note: Mistake of foreign law is treated like mistake of fact (so it can fall under mistake of fact principles and is excusable), but Indian law mistake is not excused.
(C) Section 22 – Unilateral Mistake #
Meaning #
If only one party is mistaken as to a matter of fact, the contract is not voidable merely for that reason.
Case Law: Dularia Devi v. Janardan Singh #
Facts:
Dularia Devi (illiterate/vulnerable) intended to execute a document in favour of her daughter, but the opposite side got her thumb impression on a document whose real nature was different (she believed it was one thing; in reality it operated as a sale/transfer in favour of the opposite party).
Issue:
If only one party is mistaken about what document she is signing (unilateral mistake), does that normally avoid the transaction—and what is the effect when that “mistake” is actually caused by fraud/deception about the nature of the document?
Held:
Normally, unilateral mistake alone does not avoid a contract (S.22). But here, the Court found that the “mistake” was not innocent—it was created by fraudulent intent and deception about the very character/nature of the document. Therefore, there was no real consent, and the document/transaction was treated as void (void ab initio), not merely voidable.
Conclusion #
Consent (S.13) requires consensus ad idem, i.e., true meeting of minds.
Free consent (S.14) means consent not caused by coercion (15), undue influence (16), fraud (17), misrepresentation (18), or mistake (20–22).
If free consent is absent, contracts may become voidable (mostly S.15–18) or void (especially mutual mistake under S.20).
Summary Table #
| Section | What it discusses | Effect on contract |
|---|---|---|
| 15 | Coercion | Voidable (option of aggrieved party) |
| 16 | Undue influence | Voidable (court may set aside / enforce on fair terms) |
| 17 | Fraud | Voidable |
| 18 | Misrepresentation | Voidable |
| 20 | Mutual mistake of fact (both parties) | Void |
| 21 | Mistake of law | Valid (generally; not void/voidable merely for this) |
| 22 | Unilateral mistake (one party) | Valid (generally) |
