Bhubaneswar, Mar 11 - Admitting that inclusion of 'Kui' in the list of tribals by the then NDA government at the Centre was a "mistake", former BJP minister Manmohan Samal today said dispute over fake caste certificate issue triggered violence in Kandhamal in 2008.During his cross examination before the S C Mohapatra commission of inquiry probing the Kandhamal riot, Samal said the term - Kui (a language and not a tribal sub-group) was introduced in the list of tribals in Orissa through a constitution amendment by the NDA government in 2002-03."When it was realised that the amendment may cause difficulties, our party took steps to delete it," he said during cross-examination by government pleader Bijay Patnaik.Samal, who appeared before the commission for the third day, however, said that BJP resolved about amendment of Kui term and a resolution was passed and given to the chief minister by a party delegation.A copy of the resolution was also sent to the central government. Many members of the BJP's legislature party had raised the issue in the Assembly, he said.The former minister, who had held chief minister Naveen Patnaik responsible for the Kandhamal riot, said that taking advantage of speaking in Kui language, many non-tribals obtained tribal certificates.  read more »
