Type of Law Arbitration & Conciliation Act, 1996 (Civil Procedure)
Questions of Law
  1. Does Section 31(7)(b) mandate post-award interest even if parties agree otherwise?
  2. Can an agreed 24% commercial interest rate override the statutory 18%?
  3. Are usury or public-policy grounds available to challenge an arbitral interest award?
Ratio Decidendi The Court held that clause (b) of Section 31(7) of the Arbitration Act unconditionally requires post-award interest at 18% p.a. unless the award itself fixes a different rate. Parties may contract on pre-award interest (clause (a)) but cannot “contract out” post-award interest. Challenges to interest rates on public-policy or usury grounds fail absent breach of fundamental law.

  • Morgan Securities & Credits Pvt. Ltd. v. Videocon Industries Ltd. (2023 1 SCC 602)

Logic / Jurisprudence / Authorities Relied Upon by the Court The Court distinguished clauses (a) (pre-award interest subject to party autonomy) and (b) (post-award interest mandatory). It followed precedents interpreting “unless the award otherwise directs” to qualify only the rate, not entitlement. It refused re-appreciation of evidence under Section 34(2A) and applied a restrictive public-policy test per Explanation 1.
Facts as Summarised by the Court Borrowers took two secured loans totalling ₹1.57 crore at 24% p.a., defaulted, and paid ₹44.66 lakh. NBFC invoked arbitration, and the tribunal awarded ₹2.21 crore plus 24% interest pre- and post-award. High Court dismissed challenges under Sections 34 and 37; SC appeal focused on interest and statutory interpretation.

What’s New / What Lawyers Should Note

  • Confirms that Section 31(7)(b) interest is mandatory—the arbitrator’s discretion extends only to the rate, not entitlement.
  • Parties may agree on pre-award interest (Section 31(7)(a)) but cannot exclude post-award interest.
  • Agreed commercial rate (24%) may govern post-award interest if fixed in the award; otherwise statutory 18% applies.
  • Challenges under public-policy or usury laws fail absent contravention of fundamental policy per Explanation 1 to Section 34(2)(b)(ii).
  • Section 34(2A) prohibits re-appreciation of evidence—a concurrent finding on loan genuineness and rate survives scrutiny.

Summary of Legal Reasoning

  1. Textual Divide Between Clauses (a) and (b)
    • Clause (a): Arbitrator may award pre-award interest “unless agreed otherwise.”
    • Clause (b): Mandatory post-award interest at 18% if award is silent on rate; parties cannot contract out.
  2. Precedent Analysis
    • R.P. Garg: interpreted “unless the award otherwise directs” as qualifying rate only.
    • Morgan Securities: affirmed unfettered arbitrator discretion on post-award interest.
    • North Delhi Municipal: post-award interest discourages delay in payment.
  3. Public-Policy and Usury Challenges
    • Explanation 1 to Section 34(2)(b)(ii): only fundamental policy violations warrant setting aside.
    • High commercial rate alone does not shock conscience or breach fundamental policy.
    • Usurious Loans Act, 1918 inapplicable to arbitration under 1996 Act and NBFC transactions.
  4. Procedural Bar on Re-Appreciation
    • Section 34(2A) prohibits resetting awards based on factual re-appraisal.
    • Concurrent findings on loan authenticity and 24% rate upheld by both HC benches.

Arguments by the Parties

Petitioner

  • 24% interest is unconscionable and usurious, breaching RBI fair-practice guidelines and the Usurious Loans Act, 1918.
  • Parties signed blank documents; rate interpolation amounts to fraud and vitiates contract.

Respondent

  • Section 31(7)(b) empowers arbitrator to apply agreed rate; statutory 18% fills gap only if award is silent.
  • High-risk subtype of loan to defaulting borrower justified 24% rate; State usury laws don’t bind NBFCs (Nedumpilli Finance).
  • No error in concurrent HC findings; challenge merely re-appreciates evidence, barred under Section 34(2A).

Factual Background

Sri Lakshmi Hotel Pvt. Ltd. and its MD borrowed ₹1.50 crore and ₹7.25 lakh from a NBFC at 24% p.a. Expecting 12 and 6-month tenures, they defaulted after paying ₹44.66 lakh. The NBFC invoked arbitration; award in 2014 directed payment of ₹2.21 crore plus 24% interest. High Court dismissed Section 34 and Section 37 challenges. The SC appeal centered on the arbitrator’s power over post-award interest and viability of usury/public-policy objections.

Statutory Analysis

  • Section 31(7)(a) (pre-award interest): party autonomy; arbitrator’s discretionary power can be contracted out.
  • Section 31(7)(b) (post-award interest): mandate to “carry interest at 18% p.a.” unless award stipulates otherwise; no party autonomy.
  • Section 34(2A): bars setting aside awards on re-appreciation of evidence or mere erroneous law application.
  • Explanation 1, Section 34(2)(b)(ii): “public policy” limited to breach of fundamental policy of Indian law, justice or morality—mere high rate insufficient.
  • Usurious Loans Act, 1918: not invoked in arbitration—later 1996 Act governs, NBFCs exempt from state usury statutes.
