Mr Modi raised questions about the Act 1957 while tweeting from his personal Twitter account saying, "After NCTC, the proposed amendment to Railway Protection Force Act, 1957 is another serious blow to the federal structure of the nation."
"#RPF amendment aims to give policing powers for the first time to a paramilitary unit. UPA is advocating a theory of state within a state!" added Modi while Tweeting on Wednesday, Feb 22.
Modi also accused the UPA government as he tweeted, "Centre has gone berserk in trampling with the jurisdiction of States & it's becoming increasingly evident from such consecutive actions."
Mr Modi had earlier accused the central government of doublespeak and said, though the UPA government claimed that security was a "shared" responsibility of the Centre and states, it did not bother to consult states when it came to forming laws.
"If you accept the responsibility of state governments then is it not your (Centre's) duty to consult them before forming laws?" he said opposing the Centre's plan to set up a National Counter Terrorism Centre.
Now, after NCTC, it seems that Railway Protection Force Act 1957 is one among the most concerned issues which has been haunting the BJP leader.
