Enbridge Inc. is a Calgary-based energy company that owns and operates pipelines in Canada and the U.S. It is under ongoing legal scrutiny over Line 5 and has begun rerouting aging oil pipelines around a Wisconsin tribal reservation.
The U.S. Supreme Court has unanimously ruled that Michigan's lawsuit to shut down part of the Line 5 pipeline will stay in state court. Justice Sotomayor has found that Enbridge Energy missed the deadline to move the case to federal court, reinforcing state authority over pipeline regulation amid environmental concerns.
