It's land that is owned by Indigenous People he represents.  Sohe  has more right than Trudeau to decide what happens.

What is wrong for Chief Phillips stating the truth?  Trudeau's promises are on record.  He is in fact a "serial liar".  Indigenous Nations are not Canadian.  Trudeau knows this and knows that only through agreements with the Indigenous Nations along the route can any pipeline cross BC.  Selling dilbit to Chinese industry, the only real market for west coast oil terminals, is a low value proposition for Canada and will not meet the SCOC definitions of "in the National interest".
