The Supreme Court has sided with Michigan in ruling that the state’s lawsuit seeking to shut down a section of an aging pipeline beneath a Great Lakes channel will stay in state court. Justice Sonia Sotomayor wrote for a unanimous court Wednesday that the Enbridge energy company waited too long to try to move the case to federal court. The case is part of a messy legal dispute about a pipeline that has carried crude oil and natural gas liquids between Superior, Wisconsin, and Sarnia, Ontario, since 1953. Enbridge argues the case affects U.S. and Canadian trade. The pipeline is at the center of a legal dispute in Wisconsin as well.
