An Arbitrator Can Grant Post-Award Interest on the Principal Alone: Supreme Court in Morgan Securities v. Videocon Industries

A question that has long troubled arbitration practitioners in India concerns the scope of an arbitrator's discretion when awarding post-award interest. Must the arbitrator always apply the statutory rate of eighteen percent on the entire awarded sum, including pre-award interest? Or does the arbitrator retain the freedom to tailor the interest component to the facts of the case? The Supreme Court of India, in Morgan Securities and Credits Pvt. Ltd. v. Videocon Industries Ltd., decided on September 1, 2022, has answered this question with clarity.
The Background
Morgan Securities had disbursed approximately five crore rupees under a bill discounting agreement with Videocon Industries. The dues remained unpaid. After invoking arbitration, the sole arbitrator rendered an award in 2013 granting Morgan Securities the principal sum along with pre-award interest at varying rates, and post-award interest at eighteen percent per annum on the principal amount alone. The arbitrator's decision to confine post-award interest to the principal, and not extend it to the pre-award interest component as well, became the subject of challenge before the Delhi High Court under Section 34 of the Arbitration and Conciliation Act, 1996. Both the Single Judge and the Division Bench of the Delhi High Court declined to interfere, and the matter was carried to the Supreme Court.
The Statutory Framework
Section 31(7) of the Arbitration and Conciliation Act, 1996 deals with pre-award and post-award interest. Section 31(7)(a) grants the arbitrator discretion to include interest at a rate it considers reasonable for the period between the accrual of the cause of action and the date of the award. Section 31(7)(b) provides that any sum directed to be paid by an arbitral award shall carry interest at eighteen percent per annum from the date of the award to the date of payment, unless the award otherwise directs.
The key interpretive question was whether the phrase 'unless the award otherwise directs' in Section 31(7)(b) qualifies only the rate of post-award interest, or whether it also qualifies the sum on which such interest is payable.
The Conflicting Precedents
The judgment traces the evolution of the law through two earlier decisions of the Supreme Court. In State of Haryana v. S.L. Arora, a two-Judge Bench had held that interest awarded under Section 31(7)(a) could not be included in the 'sum' for the purpose of calculating post-award interest, thus confining post-award interest to the principal. This decision was subsequently overruled by a three-Judge Bench in Hyder Consulting (UK) Limited v. Governor, State of Orissa, which held that the word 'sum' in Section 31(7)(b) carries the aggregate meaning of principal plus pre-award interest, since these two components merge upon the passing of the award and lose their separate identities. The critical question left unresolved by Hyder Consulting, however, was whether an arbitrator retained the discretion to grant post-award interest on a part of that aggregate sum, or whether post-award interest was mandatory on the whole of it.
What the Court Decided
A Bench of Dr. Justice D.Y. Chandrachud and Justice A.S. Bopanna held that the arbitrator retains wide discretion in awarding post-award interest. The Court examined the placement of the phrase 'unless the award otherwise directs' within Section 31(7)(b) and concluded that it qualifies only the rate of post-award interest, not the sum. The statutory provision of eighteen percent applies only when the award is completely silent on post-award interest. Where the arbitrator has addressed the question, even partially, the award governs.
Crucially, the Court held that the broad discretion conferred on the arbitrator under Section 31(7)(a) in respect of pre-award interest would be rendered inconsistent if the legislature had intended to strip away discretion at the post-award stage. The arbitrator, the Court observed, takes into account factors such as the financial standing of the award-debtor and the prevailing circumstances of the parties before determining the appropriate rate and quantum of post-award interest. That discretionary exercise must be performed in good faith, on relevant considerations, and reasonably. But it cannot be undone by a court merely because it chose to limit interest to the principal component.
The arbitrator's award of post-award interest on the principal sum alone was therefore upheld. The appeal was dismissed.
What This Means in Practice
For parties in arbitration, this ruling carries a practical lesson. Post-award interest is not an automatic, one-size formula. It is a matter of judicial discretion vested in the arbitrator, to be exercised contextually. An award-debtor who delays payment cannot expect a court to reduce the post-award interest on a Section 34 challenge if the arbitrator has already consciously addressed the question. Equally, where an award is entirely silent, the eighteen percent statutory rate applies on the full 'sum' as interpreted in Hyder Consulting.
For lenders and financial institutions who frequently resort to arbitration, the ruling confirms that a well-reasoned award addressing post-award interest is largely insulated from judicial tinkering at the challenge stage.
