Tribunal Rules in Favour of National Highways Authority in Tumkur–Chitradurga BOT Project Case
The National Highways Authority of India (NHAI) has secured a major legal victory after an arbitral tribunal awarded it ₹1,202 crore in a dispute related to the Tumkur–Chitradurga six-laning highway project in Karnataka. The award, one of the largest arbitration outcomes in NHAI’s favour, comes against concessionaire IRB Infrastructure Developers over premium payment defaults and revenue-sharing obligations under the Build-Operate-Transfer (BOT) agreement.
The decision strengthens NHAI’s position in enforcing concession agreements and recovering contractual dues from private infrastructure developers involved in national highway projects.
What Was the Dispute About?
The dispute originated from the Tumkur–Chitradurga six-laning project, which was awarded during 2010–11 under the Build-Operate-Transfer (BOT) model.
Under the concession agreement, the private developer was granted the right to construct, operate, and maintain the highway until June 2037. In return, the concessionaire was required to pay an annual premium of ₹140 crore to NHAI, with the payment increasing by 5% every year.
According to NHAI, the concessionaire repeatedly defaulted on premium payments over the years. Following these defaults, the authority withdrew the premium deferment facility in August 2019, citing provisions within the concession agreement.
The withdrawal of this concession became the central issue that eventually led both parties to arbitration.
What Claims Were Made During Arbitration?
Following the withdrawal of the premium deferment facility, the concessionaire sought restoration of the benefit and filed claims before the arbitral tribunal.
The company requested approximately ₹95 crore in compensation and also sought an extension of the concession period by 138 days, arguing that it was entitled to relief under the terms of the agreement.
In response, NHAI filed substantial counterclaims.
The authority demanded recovery of ₹679 crore in unpaid premium dues accumulated until November 2022. It also sought ₹96 crore for the alleged non-payment of revenue share related to the Tumkur Bypass, another component covered under the concession arrangement.
After examining the contractual provisions and claims made by both parties, the arbitral tribunal ruled largely in favour of NHAI, awarding the authority ₹1,202 crore.
The decision represents a significant financial and legal victory for the highway authority.
Why Is This Arbitration Award Significant?
The ruling is considered one of the largest arbitration awards secured by NHAI in recent years.
The outcome reinforces the enforceability of concession agreements signed under India’s public-private partnership (PPP) framework for highway development. It also sends a strong message regarding contractual compliance, particularly concerning premium payments and revenue sharing obligations.
Infrastructure experts believe the ruling could influence future disputes involving BOT projects by reaffirming that concession agreements will be interpreted strictly based on contractual commitments.
The award also strengthens NHAI’s efforts to improve financial discipline across large-scale highway infrastructure projects developed through private participation.
Delhi High Court Also Grants Relief to NHAI
In another significant legal development, NHAI recently secured substantial relief in a separate infrastructure dispute before the Delhi High Court.
The case related to the construction of the 30-kilometre Bijni–West Bengal Border four-laning highway project in Assam.
A Division Bench of the Delhi High Court significantly reduced NHAI’s financial liability in the matter.
According to the authority, the court lowered the amount payable from approximately ₹161 crore to nearly ₹36 crore, resulting in considerable financial savings for the government agency.
The ruling further strengthens NHAI’s legal position in infrastructure-related disputes and highlights its continued efforts to protect public funds while ensuring contractual accountability.
What Does This Mean for India’s Highway Sector?
The latest arbitration award and court ruling come as India continues investing heavily in highway expansion and modernisation under the National Infrastructure Pipeline and other government initiatives.
Public-private partnership models remain an important mechanism for financing large highway projects. However, disputes involving concession agreements, premium payments, project delays, and revenue sharing have become increasingly common over the past decade.
NHAI’s success in both the arbitration proceedings and the Delhi High Court demonstrates its commitment to enforcing contractual obligations while safeguarding government interests.
As India accelerates road infrastructure development, legal clarity and contractual discipline will play an increasingly important role in maintaining investor confidence and ensuring timely execution of highway projects.
The ₹1,202 crore arbitration award is therefore not only a major financial recovery for NHAI but also a significant precedent for future infrastructure disputes involving concession agreements across the country.
