The Opposition on Wednesday charged the government with failing to do justice with the victims of Bhopal gas tragedy.
"Justice and accountability has been the real casualty," Ravi Shankar Prasad (BJP) said initiating a discussion on the issue.
He said 26 years have passed and 20,000 people died in the incident and asked the government to disclose what was the exact number of deaths in its record.
Prasad said the Union Carbide had sought permission to run the plant in 1970 and it was given the nod when emergency was imposed in the country on October 31, 1975.
Referring to negligence, he said there was prior warning of gas leak as a person had died but no action was taken by the then government.
Terming the exit of the then CEO of Union Carbide Warren Anderson as a "shameful incident", Prasad said he was arrested and then escorted by the DM and the SP.
"He was allowed to go to Delhi in a state plane and from there to the United States," Prasad said.
He said, "we want to know who allowed Anderson to escape. Why action is not taken against anyone with a white skin be it Anderson or Quattrocchi?"
The BJP leader termed the Supreme Court Judgement of 1996 as "deeply regrettable" which diluted the charges against Anderson and said, "the Supreme Court treated it as a simple truck accident even as 20 thousand people had died."
He also criticised the then Chief Justice of India A S Ahmadi for becoming chairman of a hospital in Bhopal (run by the Union Carbide).
Prasad criticised the CBI for the "casual way" it treated the case and for not making attempts for the extradition of Anderson.
"Is your government going to make a sincere effort to extradite Anderson?" he asked Home Minister P Chidambaram, who was present in the House.
