Arbitrator as the Master of Evidence: Delhi High Court Reaffirms Minimal Judicial Intervention in NBCC v. Sharma Enterprises

Delhi High Court Emphasizes Arbitrator's Role: Minimal Judicial Intervention Affirmed in NBCC v. Sharma Enterprises Dispute.

Introduction

The Delhi High Court's decision in NBCC v. Sharma Enterprises (judgment dated 19 November 2025) stands as another strong affirmation of India’s arbitration-friendly judicial stance and the principle that the arbitral tribunal is the primary fact-finding authority. The judgment, delivered by Justice Jasmeet Singh in a combined adjudication of a Section 34 challenge and an enforcement petition under the Arbitration and Conciliation Act, 1996, reiterates the limited scope of interference with arbitral awards and demonstrates the judiciary’s emphasis on party autonomy, procedural efficiency, and deference to arbitral reasoning. The Court dealt in depth with contractual interpretation, extra-item claims, interest under Section 31(7)(a), and the doctrine of jurisdictional boundaries. It also revisited fundamental principles such as “arbitrator as the master of evidence” and the boundaries of the patent-illegality ground.

The judgment is particularly significant because it arises out of a protracted dispute dating back to 1991, involving termination of a subcontract at the Vashi Railway Station commercial project. The award, delivered in 2016 after multiple arbitrator appointments and litigation layers including up to the Supreme Court, awarded sums to Sharma Enterprises while rejecting NBCC’s counterclaims. The High Court’s scrutiny provides a comprehensive template for how courts ought to handle challenges under Section 34 when factual appreciation, contractual construction, and claims within the reference are contested.

Factual Background

The dispute traces its origin to a subcontract awarded by NBCC to Sharma Enterprises for flooring and cladding work at the commercial complex of Vashi Railway Station, Navi Mumbai. The original civil works were awarded to NBCC by IRCON, following which NBCC subcontracted specific works for a value of ₹9.50 crores to the respondent. The subcontract stipulated a two-year completion timeline commencing 11 January 1991. However, NBCC terminated the subcontract on 22 September 1992, citing delay and unsatisfactory performance.

The arbitration clause, located in Clause 10 of the Special Conditions of Contract, provided for reference of disputes to arbitration. When NBCC failed to appoint an arbitrator, the respondent invoked Section 20 of the 1940 Act, initiating CS(OS) 3446/1992. Over the years, several arbitrators were appointed and substituted. Ultimately, the Supreme Court in 2011 appointed a sole arbitrator to adjudicate all claims and counterclaims. The arbitral award dated 28 July 2016 partly allowed the respondent’s claims and rejected NBCC’s counterclaims. NBCC then challenged the award through proceedings which, after a series of procedural twists, culminated in the present petition under Section 34.

 

Issues Raised in the Section 34 Challenge

NBCC restricted its objections to four key issues:(1) refund of bank guarantees;(2) grant of extra-item claims;(3) award of interest; and(4) attribution of delay.

The Court evaluated each issue strictly within the contours of the limited supervisory jurisdiction under Section 34, guided by established jurisprudence including Associate Builders v. DDA, Ssangyong Engineering v. NHAI, MMTC v. Vedanta, and the principle that arbitral fact-finding cannot be reopened unless perverse or unsustainable.

Findings on Attribution of Delay

The Court upheld the arbitrator’s conclusion that the delay was attributable to NBCC rather than the subcontractor. The arbitrator had meticulously analysed documentary evidence, such as the late handover of the site office in December 1991, the failure of the main civil contractor (which NBCC had itself admitted in parallel arbitration proceedings), delayed drawings (some issued only in April 1992), and lack of utilities such as water and electricity.

The arbitrator’s findings reflected a factual matrix where flooring and cladding work could only commence upon completion of foundational civil works. Yet the civil contractor had completed merely 7% of its scope. The High Court held that these findings were rooted firmly in evidence and could not be reconsidered. Reinforcing the principle that the arbitrator is the “master of evidence”, the Court refused to reappreciate the factual record, citing precedents such as P.R. Shah Shares v. BHH Securities and Dyna Technologies v. Crompton Greaves.

Bank Guarantees and the Scope of Reference

NBCC argued that the claim for refund of bank guarantees was beyond the scope of the reference, relying on the pleadings in the original Section 20 petition. The High Court rejected this contention after noting that a prior order dated 4 December 2002 of the Delhi High Court had expressly referred all disputes concerning encashment of bank guarantees to arbitration. The arbitrator’s finding that the guarantees, save for the mobilisation advance guarantee which were refundable was, therefore, squarely within the arbitral mandate. The Court affirmed that jurisdictional objections cannot be used to reconfigure the boundaries of a reference which had already attained finality.

Extra-Item Claims and Contractual Interpretation

NBCC’s challenge to Claim I(B), relating to payment for extra items amounting to ₹26,03,465, was grounded in the argument that the contract barred the claim and that the items were already included in the original BOQ. The arbitrator had conducted a granular item-wise analysis, accepting some items (such as Items 2, 3, 4, 5, and 8) while rejecting others (Items 6 and 7) based on lack of evidence or overlap with prior payments.

The High Court held that this detailed reasoning exhibited application of mind and careful contractual scrutiny. Relying on Narendra Hirawat v. Sholay Media, South East Asia Marine v. Oil India, and Hindustan Zinc Ltd. v. Friends Coal, the Court held that once an arbitrator has interpreted contractual terms and relied on evidence, the scope of interference is severely curtailed unless the view is patently irrational, which it was not. The Court thus sustained the finding on extra items as a quintessential instance of factual and technical appreciation exclusively within the arbitrator’s domain.

Interest Under Section 31(7)(a)

A significant area of discussion concerned the award of interest at 10% per annum from the date of termination (22 September 1992). NBCC relied on Clause 26 of the GCC, arguing that the contract prohibited all forms of interest on delayed or withheld payments.

The Court analysed the contractual clause and relevant precedents including Ambica Construction v. Union of India, G.C. Roy, and Ferro Concrete Construction 2025. While agreeing that Clause 26 did not constitute an absolute bar to interest, the Court held that its language was sufficient to bar pre-reference and pendente lite interest. However, in keeping with Section 31(7)(b), post-award interest at 10% remained payable as a statutory entitlement. Thus, the Court partially modified the award only to this limited extent.

Counterclaims Rejected for Want of Evidence

NBCC’s counterclaims, ranging from recovery of materials to damages for delay which was  rejected by the arbitrator due to absence of proof, lack of quantification, and failure to establish causal links. The High Court upheld this reasoning, noting that it was well supported by evidence and consistent with precedents such as ONGC v. Saw Pipes (on proof of damages) and Kailash Nath Associates v. DDA (on inability to recover unproved losses). The Court reiterated that mere assertions cannot stand in arbitration without substantiation.

Final Decision of the Court

The Court partially allowed NBCC’s Section 34 petition solely to the extent of deleting pre-reference and pendente lite interest. Every other finding of the arbitrator, on delay, refund of bank guarantees, extra-item claims, and counterclaims, was upheld. The Court also allowed the enforcement petition, directing NBCC to pay the balance amounts within six weeks.

Conclusion and Author’s Opinion

This decision reinforces the judiciary’s settled approach: arbitral awards are not to be interfered with lightly, especially where they arise from detailed evidentiary evaluation. The Court’s reaffirmation of minimal judicial intervention is consistent with the core objectives of the Arbitration and Conciliation Act, 1996 and India’s pro-arbitration jurisprudence post-BALCO, Associate Builders, and Ssangyong. In the author’s opinion, the judgment correctly upholds the sanctity of arbitral fact-finding and respects the contractual matrix, while still ensuring that contractual bars, such as those relating to interest, are given meaningful effect. The Court struck a balanced path: preserving arbitral autonomy while ensuring that statutory and contractual boundaries are not breached. For parties involved in construction and infrastructure arbitration, the judgment is a valuable reminder that timely documentation, adherence to contractual procedures, and precision in claims are indispensable. It also underlines that challenges under Section 34 must be narrowly tailored, as attempts to reopen factual determinations will not succeed.
