The Michigan Supreme Court orders the state’s regulators to reconsider a permit tied to Enbridge’s planned oil pipeline tunnel beneath part of the Great Lakes. According to multiple outlets, the court’s decision focuses on how the permit was evaluated when it was granted. One report says the court ruled that regulators did not properly consider whether the tunnel project would extend the pipeline’s operating lifetime. As a result, the permit is not allowed to proceed as issued, and regulators must revisit the permitting decision. The decision effectively sends the matter back for further review rather than definitively blocking the project. The outlets agree that the case concerns a key permit related to the use of a tunnel to carry the pipeline under the Great Lakes and that the Supreme Court’s ruling requires additional consideration by the relevant state authorities before any further steps can be taken.
