A Canadian court on Thursday overturned approval of the Trans Mountain oil pipeline expansion, ruling that Ottawa failed to adequately consider aboriginal concerns... Trudeau’s government agreed in May to buy the pipeline from Kinder Morgan Canada Ltd for C$4.5 billion ($3.46 billion), betting it would win the court battle and expand Trans Mountain despite fierce political and environmental opposition... [T]he federal government failed to adequately consult First Nations, as required by law, [the Court] ruled. The decision also hurts Canada’s oil producers... In a statement, Kinder Morgan Canada President Ian Anderson said the court ruling was not a condition of the pipeline’s sale to Ottawa. He said the project is suspending construction. Kinder Morgan Canada shareholders voted on Thursday to approve the pipeline’s sale to Ottawa... Canada has the option to appeal the ruling to the Supreme Court but Morneau said the government had made no decisions and needs time to study the ruling.
