BC NDP STANDARD FOR INDIGENOUS CONSENT

All of the aforementioned LNG partnerships and benefit-sharing agreements were concluded with elected First Nation councils.
The leaders of the Unist’ot’en encampment reject those approvals, arguing only hereditary chiefs have jurisdiction over their traditional territories.
So is the NDP standard for consent unanimity among First Nations? Or unanimity among the clans and houses inside of a single First Nation? Or should B.C. just let the courts sort it out?
