Contract Law
Free Consent
Understand consent under Sections 13 and 14, identify what makes consent unfree, and state the correct legal effect of each vitiating factor.
The short answer
Consent exists when parties agree on the same thing in the same sense, and it is free only when no listed factor caused it.
Consent and free consent
Section 13 asks whether minds met. Section 14 asks whether that consent was freely produced.
Consent concerns agreement on the identity of the transaction, subject matter and essential terms. Free consent assumes that assent exists and asks whether a listed cause distorted the decision to agree.
The sequence matters. If the parties attached materially different meanings to an essential expression, the case may involve no consensus at all. If they understood the same transaction but one party agreed because of pressure or deception, the issue is usually whether that consent was free.
Consensus ad idem
The parties must agree upon the same thing in the same sense.
Causation
Coercion, undue influence, fraud, misrepresentation or mistake must have caused the consent in the manner recognized by law.
Evidence
Look at the relationship, statements, documents, pressure, knowledge and conduct before and after formation.
Use the correct legal effect
Defective consent does not produce one universal result.
Voidable
Coercion, fraud and misrepresentation ordinarily make the contract voidable under Section 19. Undue influence is governed by Section 19A.
Void
A bilateral mistake about an essential fact makes the agreement void under Section 20.
Generally valid
Mistake of Indian law and a unilateral mistake of fact ordinarily do not invalidate the contract under Sections 21 and 22.
Causation, proof and election
Naming a vitiating factor is not enough. The facts must connect it to the claimant's consent.
Identify the operative conduct
State the threat, dominant influence, false statement, concealment or mistake relied upon.
Connect it to consent
Ask whether the party would have entered the transaction on those terms without the identified conduct or mistake.
Use the correct burden
The ordinary claimant proves the elements, while Section 16(3) can shift the burden in an apparently unconscionable transaction involving domination of will.
Check affirmation
A party entitled to avoid a contract may lose that election by affirming it with knowledge of the relevant facts.
Remedies after defective consent
The remedy follows the classification of the defect and the election made by the affected party.
A voidable contract remains effective until the entitled party rescinds it. Sections 64 and 66 address communication and restoration when a voidable contract is rescinded. Section 19 also permits a party induced by fraud or misrepresentation, in an appropriate case, to insist on performance and be placed in the position represented.
A void agreement creates no contractual election to affirm. Restitution may still arise under Section 65 or another applicable rule, but it must be analysed separately from enforcement of the void agreement.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Raffles v. Wichelhaus
(1864) 2 H&C 906
Held: Latent ambiguity about which ship named Peerless was intended prevented a true meeting of minds.
Why it matters: Use it where identical words conceal materially different understandings.
Ningawwa v. Byrappa
AIR 1968 SC 956
Held: Fraud as to a transaction generally makes it voidable, while deception about the very character of a document may prevent real consent and make it void.
Why it matters: Use it to distinguish defective consent from a case where the mind never accompanied the act.
Read the judgmentChikkam Ammiraju v. Chikkam Seshamma
AIR 1918 Mad 414
Held: A threat to commit suicide was treated as coercion because the statutory language was not confined to an offence punishable within the territory.
Why it matters: Use it to illustrate the breadth of Section 15, then apply the present statutory wording carefully.
Raghunath Prasad v. Sarju Prasad
AIR 1924 PC 60
Held: Undue influence requires a relationship enabling domination of will and use of that position to obtain an unfair advantage; unconscionability affects the burden only after the relationship is shown.
Why it matters: Use it to structure Section 16 analysis and avoid inferring undue influence from an unfair bargain alone.

Questions students ask
Are consent and free consent the same?
No. Section 13 asks whether the parties agreed on the same thing in the same sense. Section 14 asks whether that consent was caused by a legally recognized vitiating factor.
Does defective consent always make an agreement void?
No. The result depends on the defect. Most pressure and deception cases are voidable, while bilateral mistake about an essential fact makes the agreement void.
Why is causation important under Section 14?
The listed factor must have caused the consent. Proof of a false statement, relationship or threat without a causal connection to the decision to contract may not establish defective consent.
Can a voidable contract be affirmed?
Yes. The party entitled to rescind may affirm the contract, expressly or through conduct, after becoming aware of the relevant facts. Affirmation should be distinguished from a void agreement, which cannot be validated by election alone.
What must be restored after rescission?
Section 64 generally requires a party rescinding a voidable contract to restore any benefit received under it, so far as applicable. The precise relief depends on the facts and other governing provisions.
