SC refuses to quash graft case against ex-NSE chief in co-location scam

Context

The Supreme Court refused to entertain Chitra Ramkrishna's challenge to a Delhi High Court order that allowed prosecution against her under the Prevention of Corruption Act in the NSE co-location scam, holding that questions about whether she performed a "public duty" must be decided by the trial court on merits.

Key Facts

  • The NSE co-location scam involved alleged abuse of algorithmic trading and co-location facilities by certain brokers, in conspiracy with NSE officials, between 2010-2014.
  • Ramkrishna served as joint MD (2009-2013) and later MD and CEO (from April 2013) of NSE.
  • The Delhi High Court had held that NSE, though a private company, performs a "public duty" given its vital economic function, investor protection role, and majority government-company shareholding.
  • The CBI arrested Ramkrishna in March 2022; she was granted bail in September 2022.
  • The Court held the question of whether the PC Act's "public servant" definition applies to her can be examined by the trial court, not settled at the quashing stage.
  • Significance for UPSC

    Important for GS3 (regulation of securities markets, SEBI/NSE governance, corporate accountability) and GS2 (application of anti-corruption law to quasi-public private entities). It illustrates how India's judiciary interprets "public duty" for entities with significant public/economic functions — a recurring theme in corporate governance and regulatory law questions.
