Post-Award Interest Under Section 31(7) of Arbitration Act Includes Pendent Lite Interest: Supreme Court - 2014-11-25

Defining the 'Sum' of Justice: Supreme Court Settles Debate on Arbitral Interest

In a landmark interpretation of the Arbitration and Conciliation Act, 1996 , the Supreme Court of India has finally resolved the long-standing controversy regarding whether post-award interest can be levied on a sum that includes pendente lite interest. Breaking from the restrictive view taken in State of Haryana v. S.L. Arora , a three-judge bench comprising Chief Justice H.L. Dattu and Justices S.A. Bobde and Abhay Manohar Sapre has ruled that once interest is consolidated into an award, it transforms into a "sum" capable of generating further interest.

The Backdrop: A Tug-of-War Over Interest

The dispute originated from a series of cases, most notably M/s Hyder Consulting (UK) Ltd. v. Governor, State of Orissa , where the core question was whether an arbitral tribunal is barred from awarding “interest on interest.” Under the previous S.L. Arora interpretation, it was held that Section 31(7) of the Act did not permit interest to be added to the principal for the purposes of calculating post-award interest, effectively treating such an award as "interest on interest."

However, appellants argued that once an arbitrator specifies a total sum—inclusive of the principal and pendente lite interest—that aggregate figure becomes the "sum" for the purpose of the award. Any attempt to treat the interest component as distinct from the principal after the award is made, they contended, fails to account for the commercial reality of delayed payments.

The Court’s Reasoning: Plain Language Prevails

Justices Bobde and Sapre led the charge in rejecting the S.L. Arora approach, emphasizing that the language of Section 31(7) is unambiguous. The statute does not use the word "principal," but rather the inclusive term "sum."

Justice Bobde observed, "In Section 31 (7), this particular amount of money may include interest from the date of cause of action to the date of the award... Parliament has deliberately used the word 'sum' to refer to the aggregate of the amounts that may be directed to be paid... and not merely the 'principal' sum without interest."

The court clarified that when an arbitrator merges the principal and interest into a single "sum," that total amount crystallizes into a new, single debt. Consequently, post-award interest is not "interest on interest," but rather interest on the final, aggregate debt directed by the award.

Key Observations

The judgment provides essential guidance for future arbitrations, highlighting the intent of the legislature to curb delays. The court noted:

• "Once the interest is 'included in the sum' for which the award is made, the original sum and the interest component cannot be segregated and be seen independent of each other." — Justice Abhay Manohar Sapre
• "The word 'sum' here simply means 'a particular amount of money.' In Section 31 (7), this particular amount of money may include interest from the date of cause of action to the date of the award." — Justice S.A. Bobde
• "Where the language of the Act is clear and explicit, the court must give effect to it, whatever may be the consequences, for in that case the words of the statute speak the intention of the Legislature." — Cited by Justice Bobde

Implications for Future Litigants

By overruling the restrictive interpretation, the Supreme Court has provided much-needed clarity for both claimants and debtors. This decision ensures that judgment debtors cannot profit from the time-value of money by delaying payments, as the entire awarded "sum" will now effectively attract statutory post-award interest.

The decision marks a shift toward a more pragmatic, commercial interpretation of the Arbitration and Conciliation Act , aligning Indian law with the global expectation that arbitration awards should offer a total resolution of the dispute, protecting the integrity of the sum finalized by the tribunal. In the eyes of the Apex Court, once an arbitrator has spoken, the debt is whole—and it is that whole sum that demands satisfaction through timely payment.
