It is simple, the natives make the rules and everyone else must agree or at least that seems to be the case these days. Trouble is the government can't "establish some kind of playing field where everyone knows what the rules are." when the natives can't agree among themselves what the rules are.

"this is now complicated by the fact that the government has not embraced the UN Declaration on the Rights of Indigenous Peoples, which states that First Nations must give their consent to anything that will affect their way of life before it can go ahead."

Oh yes embracing that should really get things moving LOL.
