Enbridge has gained support from numerous chambers of commerce and Republican lawmakers. The state sued to enforce the order, which is pending as a federal judge decides whether to retain jurisdiction or send the case to a Michigan state court. Business groups filed a brief in support of Enbridge, which claimed a shutdown would have "tremendous consequences" for regional and the national economies. The brief said it could mean the loss of billions of dollars in economic activity and tens of thousands of jobs in the region.
