There are several elements. We want to protect first nations with regard to the movement of populations and the storage of hazardous waste, particularly on traditional lands. Such a situation requires the express consent of the peoples concerned. That seems fundamental to me.
Article 19 of the United Nations Declaration on Indigenous Peoples also directs states to consult with indigenous peoples to obtain their consent when adopting legislation or policies that may affect the free exercise of their rights. However, the focus is on article 32, which makes explicit reference to the economics of natural resources.
Article 32(2) says the following:
States shall consult and cooperate in good faith with the indigenous peoples concerned through their own representative institutions in order to obtain their free and informed consent prior to the approval of any project affecting their lands or territories and other resources, particularly in connection with the development, utilization or exploitation of mineral, water or other resources.
We want the prior consent of first nations before any project is adopted, in accordance with the articles mentioned in the United Nations Declaration on Indigenous Peoples and their scope.
