The CBI is governed by the DSPE Act, 1946, which requires 'General Consent' from a state to investigate cases there. If a state withdraws consent, the CBI needs specific permission for new cases. In contrast, the NIA has pan-India jurisdiction under the NIA Act, 2008, and does not require state consent to investigate scheduled offenses like terrorism.

The 2026 guidelines set strict timelines: Once the Bureau of Immigration (BoI) detains someone, they must inform the originating agency immediately. The agency must take custody within 3 hours at the airport/port, or the person is handed to local police. The originating agency must then take final custody from the local police within 24 hours.

Law Enforcement Agencies (LEAs) have the power to investigate, arrest, and prosecute. IB and R&AW are 'Intelligence Agencies'. Their primary role is to collect and analyze information to prevent threats. They generally do not have the legal power to make arrests or file charge sheets in court; they pass their 'inputs' to LEAs like the Police or NIA for action.

The IT Rules 2021 require 'Significant Social Media Intermediaries' (like WhatsApp/X) to assist LEAs in identifying the 'First Originator' of information that threatens national security or public order. This allows agencies to track the source of viral fake news or illegal content, even if the platform uses end-to-end encryption.

The ED derives its power from the Prevention of Money Laundering Act (PMLA), 2002. Unlike the CrPC, under PMLA, statements made to ED officers are admissible as evidence in court, and the 'burden of proof' for bail is significantly higher (Twin Conditions). The Supreme Court upheld these powers in the Vijay Madanlal Choudhary case.

If the Bureau of Immigration (BoI) receives a direct court order to lift or suspend an LOC, they must inform the originating agency via email immediately. The agency is then mandated to respond without delay, and in no case later than 7 working days, to ensure the court's order is implemented smoothly.

Critics argue that unlike the FBI in the US, India's IB and R&AW were created by executive orders, not by an Act of Parliament. This leads to concerns about a lack of parliamentary oversight, potential misuse for political surveillance, and no clear legal definition of their powers and limitations.

An Arrest Warrant is a court order to take someone into custody. An LOC is a communication sent by an agency to immigration authorities to monitor or prevent the travel of a person. An LOC can be issued even if there is no arrest warrant, simply to ensure the person doesn't flee the country during an ongoing investigation.

A single national police could ensure uniform standards and better coordination against trans-state crimes. However, it would violate the 'Federal Structure' of the Constitution and ignore local cultural/linguistic nuances essential for community policing. The current model balances local accountability with central specialized agencies (like NIA) for national threats.

The Ministry of Home Affairs (MHA) controls most agencies, including the NIA, IB, NCB, and Central Armed Police Forces (CAPFs). However, the CBI is under the Ministry of Personnel, Public Grievances and Pensions (DoPT), and the ED is under the Ministry of Finance (Department of Revenue).
