Montana federal judge throws out key Keystone XL pipeline permit
A federal judge in Montana has thrown out a key permit needed for a developer to complete the Keystone XL pipeline.
U.S. District Judge Brian Morris of Great Falls ruled Wednesday that the U.S. Army Corps of Engineers improperly granted a permit to developer TC Energy to cross waterways to build the pipeline.
The order does not halt preliminary work that has started at the Canadian border, according to The Associated Press, but it would hinder the developer from building over waterways to complete the 1,179-mile line.
