A group of British Columbia First Nations is seeking to challenge the federal government’s second approval of the Trans Mountain pipeline expansion project in Canada’s highest court. The Squamish Nation, Tsleil-Waututh Nation, Ts’elxweyeqw Tribes and Coldwater Indian Band say they have each filed applications with the Supreme Court of Canada. They are seeking leaves to appeal a Feb. 4 decision by the Federal Court of Appeal that found cabinet’s approval of the pipeline project in June, 2019 was reasonable under the law. Tsleil-Waututh and Squamish leaders said they’re challenging the adequacy of Indigenous consultation leading up to the second approval of the oil pipeline project.
