Quantum meruit is a Latin phrase meaning “what one has earned”. In the context of contract law, It allows a person to claim reasonable compensation for work done or services provided, even when there is no valid contract or when a contract becomes void, unenforceable, or incomplete, provided the other party has accepted the benefit of that work.

This principle is closely connected with quasi-contractual obligations, especially under Section 70 of the Indian Contract Act, 1872, which prevents unjust enrichment. The doctrine ensures that no person can unfairly benefit from another’s lawful and non-gratuitous act without paying compensation.

The claim on quantum meruit generally arises in situations where:
*Work has been done without a formal contract.
*A contract becomes void or unenforceable.
*One party partially performs the contract and the other accepts the benefit.
*A contract is wrongfully terminated by one party.

State of West Bengal v. B.K. Mondal & Sons

Case Name & Citation:
State of West Bengal v. B.K. Mondal & Sons AIR 1962 SC 779
Court:
Supreme Court of India
Brief facts – The Government of West Bengal requested B.K. Mondal & Sons to construct additional structures such as temporary godowns, guard rooms, and roads for storage purposes. Although the work was completed and used by the Government, the agreement did not comply.with the formal requirements of a valid government contract under constitutional provisions. Consequently, the State refused payment for the additional construction work.

Issue – Whether the State of West Bengal is liable to compensate B.K. Mondal & Sons for construction work done without a valid formal contract, when the State had accepted and benefited from the work

RULE – The Supreme Court applied Section 70 of the Indian Contract Act, 1872, which provides that when a person lawfully does anything for another person not intending it to be gratuitous, and the other person enjoys the benefit thereof, the latter is bound to compensate the former. This provision reflects the doctrine of quantum meruit and prevents unjust enrichment.

APPLICATION– In the present case, the respondent constructed temporary storage godowns and other related structures for the Civil Supplies Department of the State at the request of government authorities. The work was carried out lawfully and according to the instructions given by the Additional Deputy Director and Assistant Director of Civil Supplies.

Further, the respondent did not intend to perform the construction work gratuitously, as the work was done in expectation of payment after completion. The construction was completed as per the estimate submitted earlier.

Moreover, the State Government accepted and enjoyed the benefit of the construction work. The Court observed that when a person lawfully does something for another and does not intend to act gratuitously, and the other party accepts and enjoys the benefit of such work, then the conditions of Section 70 of the Indian Contract Act, 1872 are satisfied.

Although there was no valid formal contract between the parties as required under constitutional provisions relating to government contracts, the State could not deny its liability after accepting the benefit of the work. Therefore, the Court applied the principle of quantum meruit and held that compensation must be paid to the respondent to prevent unjust enrichment.

CONCLUSION- In State of West Bengal v. B.K. Mondal & Sons, the Supreme Court held that since the respondent performed lawful and non-gratuitous work and the State accepted its benefit, the Government was liable to pay compensation under Section 70 of the Indian Contract Act, 1872, based on the doctrine of quantum meruit.
