The rally Gogoi and Dutta had addressed, was organised to protest the Centre's move to amend the Citizenship Act, non-implementation of the Assam Accord of 1985, lack of constitutional safeguards for the protection of indigenous peoples in the state, and a recent incident of attack on surrendered ULFA members in Nagaon.
