I don't think there's a simple answer to your question, but that doesn't mean we shouldn't be working together to find the answer that everybody can look at and say this is a reasonable implementation of the principle.
I also think this is something that's incumbent on first nations themselves to start to discuss among themselves, to talk about, well, how many...? You know, do we have referenda, or not a common mechanism? Bands and councils pass resolutions. They are what we call BCRs in the business. That represent the opinion of the chief and councillors. That constitutes the approval by the band, or the agreement by the band. Does there need to be a further referendum consultation with the members of the band?
Don't forget that the Indian Act bands are creations of the Indian Act, which means they're creations by a colonial government. If you look at the approval of a people, you're looking at broader than going beyond the boundaries of one band or another. You're looking at saying, well, we need to have the support of a majority of the people who are members of the first nations who are living along a pipeline: how do we do that?
You went from the word “consent” to “unanimous consent”.
