"Shutting down the pipeline would carry tremendous negative consequences for the Chambers' members and the economies of the United States and Canada," the brief reads. "Such a shutdown would constrain an already disrupted energy supply, an especially problematic development given recent decisions related to importation of petroleum products from Russia." Enbridge challenged Gov. Whitmer's illegal order in federal court, but the governor has asked the Court to dismiss the lawsuit based on the claim her Administration simply will not enforce the shutdown order, even though it remains in effect. "They are now trying to close the federal courthouse doors to a determination of whether the shutdown order is illegal under federal law while leaving the order in place," the brief states. "Such tactics waste judicial resources and impose significant costs on litigants."
