This civil appeal arose from a final judgment of the Division Bench of the High Court of Delhi which had dismissed an appeal under Section 37 of the Arbitration and Conciliation Act, 1996, thereby upholding a Single Judge’s order setting aside an arbitral award of pre-reference and pendente lite interest. The Supreme Court dismissed the appeal, holding that Clause 26 of the Special Conditions of Contract (SCC), which concluded with the comprehensive residuary phrase “or otherwise,” operated as an absolute contractual bar under Section 31(7)(a) of the 1996 Act preventing the Arbitral Tribunal from awarding pre-reference and pendente lite interest. The Court ruled that such a clause is analogous to clauses explicitly prohibiting interest “in any other respect whatsoever,” and since party autonomy reigns supreme under Section 31(7)(a), an arbitrator cannot act contrary to explicit contractual exclusions.
- Genesis of Dispute: A sub-contract awarded in January 1991 for flooring and cladding works at the Vashi Railway Station-cum-Commercial Complex ran into delays due to non-completion of civil works by another contractor, leading to the wrongful termination of the appellant’s contract by NBCC in September 1992. Following decades of litigation, an arbitral award was passed in July 2016 granting substantive claims as well as interest at 10% per annum across pre-reference, pendente lite, and post-award periods.
- Intervention under Section 34 and 37: While the Delhi High Court’s Single Judge and Division Bench upheld the substantive claims and post-award interest, they set aside the pre-reference and pendente lite interest based on Clause 26 of the SCC.
- Interpretation of Section 31(7)(a) of the 1996 Act: The Supreme Court reiterated that under Section 31(7)(a), the statutory power of an arbitral tribunal to award pre-award interest is explicitly subject to the opening words “Unless otherwise agreed by the parties”. When parties contract out of interest, the arbitrator, being a creature of the contract, has no jurisdiction to award it.
- Effect of the Residuary Phrase “Or Otherwise”: Addressing the appellant’s contention that ejusdem generis should limit Clause 26 exclusively to delayed running bills, the Court held that the clause disjunctively lists independent contingencies (withheld balances/deposits, delays in monthly/final payments, or otherwise). The concluding phrase “or otherwise” acts as a residuary clause of wide amplitude, putting it on par with expressions like “or in any other respect whatsoever”.
- Distinction between Pre-Award and Post-Award Interest: The Court underscored that while pre-award interest under Section 31(7)(a) is subject to party autonomy and contractual exceptions, post-award interest under Section 31(7)(b) is mandatory and cannot be contracted out of by parties.
- Final Ruling: The Supreme Court dismissed the appeal, affirming the concurrent decisions of the High Court that set aside the pre-reference and pendente lite interest while leaving the substantive claims and post-award interest intact.
