Michigan Supreme Court rejects permit for Enbridge oil pipeline under Great Lakes

The Michigan Supreme Court rejected a permit for Enbridge's proposed tunnel to house its Line 5 oil pipeline under the Great Lakes, citing insufficient environmental review. The court found regulators failed to assess whether the tunnel would extend the pipeline's lifespan and cause greater harm, while environmentalists and tribal nations oppose the project due to spill risks and cultural significance. Enbridge argues the tunnel would enhance environmental protection and energy reliability.
