The 'one nation, one test' proposal was a unanimous decision of the IIT Council taken in accordance with the IIT Act passed by the Indian Parliament, he told reporters here when asked to comment on the controversy over the proposal, which has been opposed by IIT Kanpur among others.

Arguing that the decision of the IIT Council is in tune with the international practices, Sibal asserted: "There is no intent to impact on the IIT system autonomy. The exam that is being contemplated is to be set by the IIT itself."
