In February 2016 a federal judge issued an injunction that prohibited work on the 500 kV line until the Waimiri-Atroari indigenous people had been consulted . He said IBAMA had ignored the requests of the indigenous people and forced through the project without consultation , as required by the Indigenous and Tribal Peoples Convention , 1989 . Although public hearings had been held in the cities of Presidente Figueiredo , Manaus , Rorainópolis and Boa Vista , none had been held in the Waimiri Atroari Indigenous Territory . A leader of the indigenous people said FUNAI could not speak on their behalf concerning the project . The Convention required free and informed prior consultation . The Waimiri Atroari had already suffered from a history of " violent pacification " , illegal mining and flooding of sacred territories , as with the Balbina Dam . Construction would involve hundreds of workers entering the territory , where FUNAI considers that more than 1,600 Indians are " recent contact " . The Indian leaders said that there were already problems in the community and conflicts since BR-174 was opened
