The James Bay and Northern Quebec agreements were amended by some twenty additional agreements concerning the implementation and terms of the original agreement, as well as by the expansion of their provisions. In addition, the Constitution Act of 1982 enshrined in the Canadian Constitution all rights granted in treaties and land rights prior to 1982 and gave the rights described in the original agreement the status of constitutional rights. However, more than thirty amendment agreements, ancillary agreements and relevant laws illustrate the complexity and dynamics of the agreement. In 1984, the Canadian Parliament kept its promise of Aboriginal autonomy and passed the Cree-Naskapi (Quebec) Act, the first of its kind at the national level (see Aboriginal Autonomy in Canada). The Naskapi joined the JBNQA in 1978 by signing the Northeastern Québec subsidiary agreement. The James Bay and Northern Quebec Accord (JBNQA) is a legally valid agreement signed on November 11, 1975 by the Government of Quebec, the Government of Canada, Hydro-Québec and two of its subsidiaries, the Grand Conseil des Crees du Québec and the Inuit Association of Northern Quebec. The JBNQA redefined and reformulated land management and the relationship between the State of Quebec and the Indigenous peoples of James Bay and the Northern Quebec region (see James Bay Project, Contracts with Indigenous Peoples in Canada). That ruling was overturned seven days later by the Quebec Court of Appeal after the government`s failed efforts to quickly negotiate an agreement. Nevertheless, the legal requirement that Quebec negotiate a contract on the territory has not been lifted, although construction continues. .
