An employer engages a contractor, fixes a completion date, and writes a liquidated damages clause into the contract so that every day of delay costs the contractor a stipulated sum. Then the employer delays the work itself: the site is handed over late, approvals are slow, the ground is occupied when the contractor arrives. When the job overruns, can the employer still deduct liquidated damages? Indian law answers, in most such cases, no. The prevention principle holds that a party cannot claim the benefit of a term when its own act has prevented performance. This explainer sets out the statutory foundation of that principle in the Indian Contract Act 1872, the doctrine of "time at large," the role of extension-of-time clauses, the treatment of concurrent delay, and how arbitral tribunals and courts have applied all of this in construction and works contracts.
The Statutory Foundation: Sections 53 and 55
The prevention principle in Indian law is not a free-floating equity. It is grounded in the Indian Contract Act 1872, principally Sections 53 and 55. Section 53 deals with reciprocal promises and the consequence of one party obstructing the other:
"When a contract contains reciprocal promises, and one party to the contract prevents the other from performing his promise, the contract becomes voidable at the option of the party so prevented; and he is entitled to claim compensation for any loss occasioned by the non-performance of the promise."
Section 55 governs the effect of a failure to perform at a fixed time: where time is of the essence, where it is not, and where performance is accepted at a time other than that agreed. Together these provisions carry a single premise: no party may insist on strict performance to a deadline when that party's own conduct has materially hindered or prevented performance to that deadline. The doctrine reflects the wider principle, deeply embedded in Indian jurisprudence, that no one may take advantage of his own wrong.
The principle bites hardest in construction and supply contracts where time is of the essence. There the employer holds many of the levers that decide whether the contractor can finish on time: site access, materials, drawings, approvals and payments. When it fails to pull those levers in time and then charges the contractor for the resulting overrun, Sections 53 and 55 supply the answer.
