The Supreme Court of Canada has denied leave to appeal a decision by the Federal Court of Appeal from September 4th, 2019 which significantly limited the grounds that the First Nations, including Tsleil-Waututh, could argue in the recent Coldwater case.  Tsleil-Waututh announced today that they would appeal the Coldwater decision, which upheld the approval of  the Trans Mountain Expansion Project (TMX) after finding consultation to be adequate.
