"WINNIPEG, Manitoba - A Canadian court ruled on Friday that a federal carbon-pricing plan does not violate the constitution, marking a victory for Prime Minister Justin Trudeau over one of his trademark policies ahead of the October national election.

In a 3-2 decision, the Saskatchewan Court of Appeal rejected a challenge from the conservative provincial government, which argued the tax could not be imposed by Ottawa.

Trudeau, citing international commitments on global warming, four years ago campaigned on a promise to introduce a plan to fight climate change, and on April 1, he slapped a federal tax on the four provinces that had refused to introduce their own carbon-reduction plans."
