Michigan Supreme Court rejects permit for Enbridge oil pipeline under Great Lakes.
The Michigan Supreme Court has ordered state regulators to reconsider a key permit that allowed a planned tunnel to carry an oil pipeline under part of the Great Lakes to move forward.
The 6-1 decision further clouds the future of the 73-year-old pipeline owned by Canadian energy transportation company Enbridge that carries petroleum from Superior, Wisconsin, to Sarnia, Ontario.
