Lok Sabha passed the National Investigation Agency (Amendment) Bill, 2019 on Monday after a heated debate between Home Minister Amit Shah and the Opposition.

The Bill amends the National Investigation Agency (NIA) Act, 2008 that provides for a national-level agency to investigate and prosecute offences listed in the scheduled offences. Further, the Act allows for creation of Special Courts for the trial of scheduled offences.

The Bill seeks to allow the NIA to investigate the following offences in addition to human trafficking, offences related to counterfeit currency or bank notes, manufacture or sale of prohibited arms, cyber-terrorism and offences under the Explosive Substances Act, 1908.

Refuting Opposition claims over "misuse" of the NIA law, Amit Shah on Monday asserted that the Modi government will never misuse it on the basis of religion but ensure that terrorism is finished off irrespective of the religion of the accused.

In an intervention during a discussion in Lok Sabha on the National Investigation Agency (Amendment) Bill, 2019, Shah also targeted the Congress-led UPA government for repealing the anti-terror act POTA, saying it was not done because of its alleged misuse but to "save its vote bank".

While Minister of State for Home G Kishan Reddy sought support of all parties for the passage of the National Investigation Agency (Amendment) Bill, 2019, Manish Tewari of the Congress accused the government of trying to turn India into a "police state".

Reddy told the House that the new law will allow the NIA to probe cases of terrorism targeting Indians and Indian assets abroad, and also empower the agency to investigate cases of arms and human trafficking besides those linked to cyber terrorism.

He said terror attacks witnessed an uspurge after the Prevention of Terrorism Act (POTA) was repealed resulting in the same UPA government being forced to constitute NIA after the Mumbai attacks.

Shah sought all-party support for the Bill's passage, saying a division in the House on the issue of strengthening the agency will send out a wrong message and boost the morale of terrorists.

Parliament should speak in one voice in giving powers to the NIA to send out a message to terrorists and the world, he asserted.

His response came as several opposition leaders criticised the bill and accused the government of using investigating agencies for "political vendetta".

Some MPs said the anti-terror law is misused at times to target members of a particular community.

"Let me make it clear. The Modi government has no such intention. Its only goal is to finish off terrorism but we will also not look at the religion of the accused while taking action," Shah said.

Tewari opposed the bill, saying probe agencies are misused for "political vendetta" and "inspired media leaks" from them have turned the maxim of "innocent until proven guilty" on its head.

He also claimed that the constitutional validity of the NIA Act, which led to the investigation agency's formation, is still not settled as pleas challenging its validity are pending in different courts.
