L&T's ₹13.08 Crore Arbitral Award Set Aside by Karnataka High Court on Contract Dispute

The Karnataka High Court has partially set aside a ₹13.08 crore arbitral award granted to Larsen & Toubro Limited (L&T) in a dispute arising from a ₹303.29 crore Bengaluru Metro construction contract. In a significant ruling, a Division Bench comprising Chief Justice Vibhu Bakhru and Justice K.S. Hemalekha found that the Arbitral Tribunal had failed to properly consider evidence and contractual provisions, rendering portions of the award unsustainable under Section 34 of the Arbitration and Conciliation Act, 1996.

The court underscored the limited scope of judicial review under Section 34, noting that while it cannot re-appreciate evidence or substitute its opinion for that of the tribunal, an award must be set aside if the tribunal disregards relevant material. This principle guided the court’s analysis of four key claims advanced by L&T against the Bangalore Metro Rail Corporation Limited (BMRCL).

Background: A Prolonged Construction Contract

The dispute centered on L&T’s contract to construct approximately 4.80 km of elevated viaduct and three elevated stations for the Bengaluru Metro. The original contract period was set to end on December 16, 2011, but delays in site handover by BMRCL led to significant prolongation of the work. L&T subsequently claimed additional costs for reduced quantities, revised rates for delayed pier locations, unpaid reinforcement work, and time-related overheads during the extended period.

The Arbitral Tribunal had awarded L&T a total of approximately ₹13.08 crore across these claims, but BMRCL challenged the award before the High Court, arguing that the tribunal had erred in its reasoning and ignored contractual defenses.

Parapet Quantities: A Flawed Computation

One of the claims involved reduced quantities of parapet work. L&T had claimed ₹4.23 crore after the scope of parapet construction was substantially cut. The tribunal awarded ₹96.43 lakh by calculating the amount at 20% of the cost of the quantity reduced beyond the permissible 25% variation. The High Court found this computation neither based on L&T’s actual claim nor supported by any evidence on record. It observed that the tribunal had essentially invented a formula without linking it to the contractual framework or the proof submitted. Consequently, the award on this head was set aside.

Revised Rates for Delayed Pier Locations

L&T sought ₹9.80 crore for revised rates on 18 pier locations that were handed over beyond the original contract period. Eight locations were released in January 2013, and the remaining ten on January 4, 2014. The tribunal awarded ₹9.27 crore, effectively granting most of the claim. However, the High Court noted that the tribunal had failed to consider BMRCL’s defense based on contractual provisions governing delayed site handover. The contract contained specific clauses that limited L&T’s entitlement to revised rates in such scenarios, and the tribunal’s award did not address these clauses. The court therefore set aside this portion as well, holding that the tribunal had overlooked a critical contractual defense.

Reinforcement Claim: Including Unsupported Items

On the reinforcement claim, L&T had demanded ₹3.15 crore for unpaid quantities, and the tribunal awarded ₹2.84 crore. The High Court, however, pointed out that BMRCL’s Engineer had certified that piling guide rings and spacers were already included in the accepted rates. Despite this, the tribunal’s award appeared to include these items again, resulting in double counting. The court found this portion unsustainable and set it aside, emphasizing that the tribunal must base its findings on the Engineer’s certifications and contractual rates.

Time-Related Costs: A Failure to Consider Relevant Material

The most substantial claim was L&T’s demand for ₹103.30 crore in time-related costs arising from the prolonged contract period. The tribunal found that the delay was attributable to BMRCL and held that L&T was entitled to such costs in principle. However, it rejected the claim on the ground that L&T had failed to establish the quantum of damages, relying heavily on an American Appraisal report that the tribunal deemed insufficient.

The High Court found this reasoning flawed. It noted that L&T had produced other relevant material—including internal records, project schedules, and contemporaneous correspondence—to substantiate its overheads and lost profit. The tribunal’s focus solely on the American Appraisal report was erroneous, as it disregarded other admissible evidence. The court held that the tribunal had “proceeded on the erroneous basis that the quantification rested entirely on an American Appraisal report” and failed to consider the broader evidentiary record.

Accordingly, the High Court set aside the tribunal’s finding on entitlement to time-related costs and its rejection of the claim for want of proof of quantum. It left these claims open to be “agitated afresh, if so advised,” meaning L&T may pursue them in fresh arbitration proceedings or other appropriate forums.

Legal Analysis: The Standard of Review Under Section 34

The judgment reaffirms the well-settled principle that courts under Section 34 do not sit in appeal over arbitral awards. The power to set aside is limited to grounds such as patent illegality, violation of public policy, or failure to consider relevant evidence. The High Court’s intervention here was justified because the tribunal had disregarded contractual provisions and material evidence—a clear ground for annulment.

The court’s observation that “if the Arbitral Tribunal has disregarded evidence or material which is relevant, the arbitral award would be liable to be set aside” provides a crucial reminder to tribunals: they must engage with all evidence presented, not cherry-pick convenient sources. This ruling reinforces the importance of a reasoned award that addresses both parties’ submissions.

Impact on Construction Arbitration Practice

For legal professionals handling infrastructure and construction disputes, this judgment offers several practical takeaways. First, tribunals must carefully examine contractual clauses governing variations, delays, and rate revisions. A failure to do so invites judicial interference. Second, quantification of claims—especially time-related costs—requires a holistic assessment of available evidence, not reliance on a single report. Third, parties should ensure that their claims are precisely pleaded and supported by documentary proof, as courts will not fill gaps in the tribunal’s reasoning.

The decision also highlights the vulnerability of awards that appear to ignore the engineer’s certifications or contractual mechanisms. BMRCL’s success in challenging the reinforcement claim underscores the importance of contractual defenses being explicitly addressed in the award.

Conclusion

The Karnataka High Court’s partial setting aside of the arbitral award sends a strong signal that tribunals must adhere to procedural fairness and evidentiary standards. While the court respected the limited scope of Section 34, it did not hesitate to correct errors where the tribunal had strayed from its duty to consider relevant material. For L&T, the path to recovering time-related costs remains open, but the company must now re-agitate its claims. For BMRCL, the ruling provides relief from what it considered an inflated award. The case serves as a valuable precedent for the interplay between contractual interpretation and arbitral reasoning in large-scale infrastructure projects.
