Addressing the gathering Rakesh Singha, general secretary CPI(M) said that because of religious sanction, social discrimination had become legitimized.
On the basis of a survey of dalit households conducted by the party, he said that more than 50 forms of social discrimination were being practiced in the hill state.
The party has drawn up plans of submitting a memorandum to the government over implementation of land reforms by seeking allotment of fresh land to the poor, with dalits being the majority among the poor.
The party also sought that 85th constitutional amendment be implemented in letter and spirit and the state draw up a special plan for dalit households and villages with respect to infrastructure development such as roads, education, drinking water and irrigation and MNREGA.
Speakers also sought extension of reservation to the private sector.
