A two-judge bench of the apex court disposed of the petitions after being informed that the market regulator and India’s premier stock exchange had formally agreed to a massive Rs 1,491.21 crore settlement. Under the consent settlement framework, the NSE finalized the deal without admitting or denying guilt.
Final Payment Clears Long-Standing Regulatory Hurdle
The high-profile resolution comes shortly after the NSE remitted Rs 714.74 crore to SEBI in July, having received in-principle approval to settle both the co-location and dark fiber proceedings. That transfer, combined with an earlier deposit of Rs 776.47 crore, fully satisfies the Rs 1,491.21 crore settlement requirement.
The Supreme Court’s order brings a definitive end to civil regulatory action against the exchange itself, providing long-awaited regulatory clarity for market participants and investors.
Origins of the Decade-Long Scandal
The dispute traces back to 2015, when whistleblowers and investigative reports alleged that select high-frequency trading firms were granted unfair, preferential access to the NSE’s electronic servers.
Through the exchange’s co-location facility—where institutional servers are physically placed in the same data center as the exchange's matching engine—certain brokers allegedly obtained split-second access to price data. Investigators revealed that favored brokers gained unauthorized access to secondary backup servers and set up direct point-to-point dark fiber lines through unlicensed telecom operators, bypassing traffic on primary servers and securing an unfair trading edge.
The scandal severely damaged the credibility of the exchange, triggering executive reshuffles and high-profile departures. Former NSE Chief Executive Officers Chitra Ramkrishna and Ravi Narain, alongside Group Chief Operating Officer Anand Subramanian, were forced out amid intense scrutiny.
While SEBI closed administrative proceedings against individual top executives in 2019 due to insufficient evidence of direct collusion, parallel criminal investigations by the Central Bureau of Investigation (CBI) remain ongoing.
Clear Runway for Landmark NSE IPO
The protracted legal dispute had stalled the exchange’s public listing plans for years. In 2019, SEBI originally directed the NSE to disgorge Rs 625 crore plus interest and barred it from tapping capital markets. Although the Securities Appellate Tribunal (SAT) subsequently set aside that penalty, SEBI appealed the ruling to the Supreme Court.
With the Supreme Court now disposing of SEBI's appeal under the consent mechanism, the regulatory roadblock standing between the exchange and public markets has been lifted.
The resolution paves the way for the NSE's long-anticipated initial public offering (IPO). Having submitted a draft prospectus to SEBI in June for an offer-for-sale (OFS) of nearly 6 percent of its equity shares held by existing investors, the market powerhouse is now poised to move forward with one of the most anticipated market listings in Indian history.
