Enbridge Energy has asked a Michigan judge to delay a decision on the state's lawsuit over the Line 5 pipeline, urging the court to wait for U.S.-Canada treaty talks to progress. Michigan Attorney General Dana Nessel's lawsuit challenges the pipeline's easement through the Straits of Mackinac, citing safety concerns. Enbridge argues the dispute is under federal jurisdiction and should be resolved through diplomatic negotiations. The judge has not yet issued a ruling.
