Delhi High Court Clarifies Limited Scope of Section 34 Review, Upholds Arbitral Award on Prolongation Costs, GST, and Statutory Variations

The Delhi High Court, in a detailed judgment delivered by Justice Subramonium Prasad, has dismissed a petition under Section 34 of the Arbitration and Conciliation Act, 1996, challenging a majority arbitral award dated 28 April 2021. The award, arising from disputes between the parties over a contract for the construction of an elevated viaduct and stations for the Delhi Metro, had allowed several claims by the contractor, including those for prolongation costs, GST/statutory tax variation, minimum wage escalation, and environmental compensation charges (ECC).

The petitioner, Delhi Metro Rail Corporation Ltd., objected to the award on multiple grounds, including the methodology adopted by the tribunal for quantifying prolongation costs, the allowance of GST and wage escalation claims despite contractual clauses allegedly barring such adjustments, and the reimbursement of ECC. The petitioner argued that the tribunal relied on assumptions, failed to demand sufficient documentary evidence, and misapplied contractual provisions, thereby rendering the award vulnerable to challenge for patent illegality and violation of the fundamental policy of Indian law.

The Court, after a comprehensive review of the arbitral record and the parties’ submissions, clarified the contours of judicial intervention under Section 34. It reiterated that the jurisdiction of the court is supervisory, not appellate, and that errors of fact, sufficiency of evidence, or mere differences in contractual interpretation do not justify interference. The Court emphasized that only patent illegality apparent on the face of the award, contravention of the fundamental policy of Indian law, or conflict with the most basic notions of justice or morality can warrant setting aside an arbitral award.

On the issue of prolongation costs, the Court found that the tribunal had examined the evidence, delay matrix, and contractual framework before attributing delay to the petitioner and quantifying damages using industry-accepted norms. The Court held that the tribunal’s adoption of a 10% parameter for overheads and a proportionate approach for plant and machinery idling charges was a reasonable quantification exercise within its domain, not an arbitrary or unsupported assumption. The Court further noted that the tribunal had relied on expert evidence and contemporaneous records, and that the petitioner’s objections essentially sought a re-evaluation of evidence, which is impermissible under Section 34.

Regarding GST and statutory tax variation, the Court upheld the tribunal’s interpretation that the introduction of GST, which occurred during an extended period attributable to the petitioner’s delay, imposed an additional financial burden on the contractor not fully contemplated at the time of bidding. The Court found that the tribunal’s construction of the relevant contractual clauses was plausible and not contrary to the express terms of the contract. Similarly, the Court accepted the tribunal’s reasoning that the bar on wage escalation in the contract could not operate to deny compensation for increased minimum wages during a period of delay caused by the employer.

On the claim for environmental compensation charges, the Court agreed with the tribunal that ECC, imposed pursuant to Supreme Court directions, did not fall within the meaning of “tax,” “duty,” or “levy” as contemplated by the exclusion clauses in the contract. The tribunal’s reliance on the contract’s general claims procedure and its verification of actual payments made by the contractor were found to be sound and supported by the record.

The Court also addressed the direction regarding payment of applicable taxes on the awarded amounts, holding that such a direction is a natural legal consequence in the absence of an express contractual prohibition and does not amount to rewriting the contract.

In its analysis, the Court relied on a series of Supreme Court and High Court precedents, including McDermott International Inc. v. Burn Standard Co. Ltd., Associate Builders v. DDA, Ssangyong Engineering & Construction Co. Ltd. v. NHAI, and Delhi Metro Rail Corporation Limited v. Delhi Airport Metro Express Private Limited, to underscore the limited and restrictive scope of Section 34 review. The Court emphasized that as long as the arbitral tribunal’s view is plausible, reasoned, and based on the material on record, the court cannot supplant it with its own reasoning or interpretation.

Ultimately, the Court found no patent illegality, perversity, or conflict with the fundamental policy of Indian law in the majority arbitral award. The existence of a dissenting award was held not to dilute the binding character of the majority decision. The petition under Section 34 was accordingly dismissed, with all pending applications disposed of and no order as to costs.
