Supreme Court Sounds Alarm on NIA's Core Powers in High-Stakes PIL

In a hearing that underscored profound constitutional concerns, a Supreme Court bench led by Justices Vikram Nath and Sandeep Mehta issued notice on Writ Petition (Civil) No. 320/2026 , a public interest litigation challenging the validity of the National Investigation Agency (NIA) Act. The court also addressed connected special leave petitions arising from a Kerala High Court order, granting the NIA time to bolster its response while de-tagging the PIL for separate listing on July 14, 2026 .

Roots of the Constitutional Clash

The dispute traces back to SLP(Crl.) No. 3658/2024 , filed by Sadik A P @ Sadiq Ahmed and others against the Union of India and others, challenging a December 1, 2023 , order from the High Court of Kerala at Ernakulam in WPCRL No. 1044/2023 . These criminal appeals question the NIA's investigative overreach. Paralleling this is the PIL, which directly attacks the NIA Act's framework, probing whether the agency legally holds powers akin to police—specifically, registering FIRs, filing chargesheets, and conducting investigations without explicit statutory backing.

Petitioners argue the NIA Act lacks provisions designating its officers as "police officers" under the CrPC , potentially invalidating ongoing probes nationwide. The timeline escalated with interim applications for vacating stays, exemptions from filing certified copies, and permissions for additional documents, all heard on April 21, 2026 .

Bench Grills NIA on Fundamental Flaws

During oral arguments, Additional Solicitor General Aishwarya Bhati represented the NIA and Union of India , facing sharp queries from the bench. Justices Nath and Mehta zeroed in on operational realities: “If NIA doesn’t have power to register FIR, what would be the result of your investigation? Are their officers considered to be police officers? How do you file a chargesheet? Is there any notification to that effect?”

The court emphasized the stakes: “These are questions of vital importance affecting the entire country.” Petitioners, through senior advocates like Basant R and Siddhartha Dave , highlighted the absence of explicit empowerment, urging scrutiny of the Act's vires amid national security implications. The NIA sought adjournments to furnish supporting documents, revealing the agency's reliance on implied or notified powers under the Act.

No prior precedents were cited in this procedural order, but the bench's observations signal potential reliance on foundational cases interpreting special agency statutes like the UAPA or PMLA , where police-like powers hinge on legislative clarity.

Key Observations from the Bench

  • “If NIA doesn’t have power to register FIR, what would be the result of your investigation?” – Highlighting risks to ongoing cases.
  • “These are questions of vital importance affecting the entire country.” – Underscoring nationwide ramifications.
  • Directions for the NIA: Granted a week's time to file an additional affidavit with documents, with relisting on April 28, 2026 , for the SLPs.

Roadmap Ahead: Notices Issued, Clocks Ticking

The Supreme Court ordered the Centre to file a counter affidavit within four weeks for the PIL, with petitioners getting two weeks for rejoinder. The SLPs (Nos. 3658/2024 and 4384/2024) remain linked for now, minus the de-tagged PIL. Other applications—like withdrawals and permissions—stand noted.

This procedural pivot sets the stage for a landmark ruling on the NIA's mandate, potentially reshaping counter-terrorism probes across India. If the Act falters, thousands of cases could face collapse, amplifying the bench's caution on "wide national importance."
