New Delhi: Details of use of state government plane to ferry Union Carbide Chairman Warren Anderson out of Bhopal in 1984 are not available with the Madhya Pradesh government, state's aviation directorate has said.

Responding to an RTI application seeking to know who had sanctioned the flight which took Anderson to Delhi soon after the Bhopal gas tragedy in December 1984, the aviation directorate, said information is not available as the matter is 26-year-old.

The information under the Right to Information Act should be provided within one month of receiving the application but the Aviation Directorate which got the application on June 26, 2010, did not respond to it till March 26, 2011. The reply came only after a complaint against it was filed with the State Information Commission.

The applicant had sought to know regarding the sanction of the flight, name of person who sanctioned it, details about the names and number of passengers in it.

Anderson had reached Bhopal from the US three days after the gas tragedy struck the city on the intervening night of December 2-3, 1984.

But he left the country on December 7 and remained evasive since then. He was allegedly allowed to use an aircraft of Madhya Pradesh government to come to Delhi from Bhopal from where he returned to the US.

The CBI has been pursuing the matter of extradition of Warren Anderson since 1993.

However, the US did not agree for extradition of Anderson stating that the request of India does not meet the requirements of dual criminality under Article 2(1) and 9(3) of the extradition treaty between the two countries.
