 One of the key points out of the CBI is the approval of 2016 clearances given by his ministry in a span of two years from 2006 to 2008, some of which were associated with trading of hazardous waste.The other issue raised was about the large majority of Raja's supporters in the expert appraisals committee (EAC), responsible for granting clearances to various sectors.In 2007 May, Dinakaran, the newspaper run by Kalanidhi Maran, the elder brother of Dayanidhi Maran who was the central minister for IT and Communication, ran into a controversy when it published the results of a series of opinion polls which showed M. K. Stalin, the second son of Karunanidhi, having more approval (70%) than his elder brother M. K. Azhagiri (2%) as the political heir of Karunanidhi.
