When he was asked whether Bhopal mishap is a closed case or not, Crowley said "Yes. It's a closed case."
However, later the State Department official clarified that legally Bhopal gas case is closed.
Meanwhile, BJP and Left parties on Thursday alleged that the US was trying to arm-twist India to let Dow Chemicals go scot-free with regard to its liability in the Bhopal gas tragedy.
A Union Carbide plant in Bhopal spewed toxic gas into surrounding neighborhoods, killing thousands instantly and tens of thousands later in Dec 1984.
In 1999, Dow Chemical Company bought the Union Carbide which was responsible for the world's worst man-made disaster in 1984, the Bhopal gas tragedy.
After 26-year of the tragedy, a court sentenced seven Indian managers to two-year jail terms in 2010.
But public outrage that the sentences were not tougher, India promised to renew efforts to extradite Union Carbide's former boss Warren Anderson.
