"The CBI has been consistently pursuing the matter of extradition of Warren Anderson since 1993," Minister of State for Personnel Prithviraj Chavan said in a written reply in the Rajya Sabha.
However, the US Department of State did not agree for extradition of Anderson in the Bhopal gas leak case stating that the request of the Government of India does not meet the requirements of dual criminality under Article 2(1) and 9(3) of the Extradition Treaty, he said.
"The CBI has sent additional evidence to the Ministry of External Affairs against Warren Anderson for his extradition on July 29, 2010," he said.
