As expected, Michigan has appealed a recent court decision to allow construction of a tunnel under the Straits of Mackinac.
The tunnel would be built by Enbridge, the company that owns the aging and controversial Line Five pipeline that carries petroleum product across the straits.
The deal to remove the pipeline from the lake bed and place it in a tunnel was struck during the closing days of the administration of Governor Rick Snyder.
Governor Gretchen Whitmer opposes the plan, and Attorney General Dana Nessel filed suit to stop it.
A Court of Claims judge recently ruled against Nessel.
Nessel is also pursuing a separate lawsuit to force Enbridge to stop using the existing pipeline immediately.
