Observing that Singh had alleged that the Left was responsible for the AIIMS amendment bill being passed in Rajya Sabha without referring it to the Standing Committee, senior CPI(M) leader Basudeb Acharia said "the fact is that the bill was introduced in Lok Sabha and adopted there first. Subsequently it was taken up in the Rajya Sabha."

Acharia, the party leader in Lok Sabha, said "as far as the CPI(M) is concerned, we got a clause deleted which would have detracted from the autonomy of the institute. There was no question, therefore, of the Bill being referred to the Standing Committee in the Rajya Sabha. Amar Singh should check up these facts before making such statements," Acharia said.
