Prof. Mr. Kalvimani and Mr. Ramesh, a human rights activist, is a human rights activist, retired Professor from Tindivanam, who independently runs school in Tamil Regional Language from his own resources. They undertook the case of the assault on four Irula Tribal women to get justice for them. They organised those victims and sought for justice before the Judicial Magistrate. Meanwhile, the Leader of the Tribal People's Liberation Party, Mr. Thangamani, asked Prof. Kalvimani and Ramesh to withdraw their activities regarding the case and he will handle it. On that day when the case came for hearing before the Judicial Magistrate, the victims made it clear that they were in favor of Ramesh, who took forward their complaint. Prof. Kalvimani also accompanied them to Court on that day. While they were about to take the vehicle Mr. Thangamani allegedly blocked them from taking the vehicle by lying down on the road. Later the District Superintendent of Police came to the spot to clear the problem. In this connection, Mr. Thangamani has filed a false charge against Prof. Kalvimani and Mr. Ramesh under the SC/STs Atrocities Act on false allegations that they used abusive and filthy words against those Irula Tribal women and defamatory statements based on their caste. Mr. Thangamani's allegations were false and it shows that he did not want Prof. Kalvimani - a non-tribal person - to get involved in this case related to the assault of women of his Irula community.
