Dear Mr.Ashok,
As of now the Central list of OBC does not incorporate all castes/ communities found in State lists. You cannot get OBC certificate until Government of India has incorporated your caste in Central OBC list for Tamil Nadu.
The judgement of Supreme Court in Mandal case is that the State lists should prevail over Mandal list. As and when the State list is updated with new entry by the State Government, such information has to be sent to the Government of India. The Central Government should examine the information and make necessary changes in its list of OBC. If it has any objection for such inclusion, Central Government has to inform the State reasons as to why it should be excluded from the State list. This is not being done. The Central Government continues to create disparity between State list and Central list. Website (
www.ncbc.nic.in/Pdf/Tamil%20Nadu/Tamilnadu-Vol2/1.pdf )discloses the reasons for not including your community in OBC list of Central Government. The reasons are baseless. The Central Government has not obeyed the judgement of Supreme Court in Mandal case.
