BISMARCK, N.D. (AP) -- American Indian tribes fighting in court to shut down the Dakota Access pipeline are objecting to the possible intervention of national energy and manufacturing trade groups in the dispute.
The groups want a say because they maintain a shutdown of the $3.8 billion pipeline moving North Dakota oil to Illinois would adversely impact the oil industry.
Tribal attorneys say the groups' arguments are lengthy and duplicate those already made by Texas-based pipeline developer Energy Transfer Partners and federal officials who permitted the project.
U.S. District Judge James Boasberg last month ordered the Army Corps of Engineers to further review the pipeline's impact on the Standing Rock Sioux. He's deciding whether to shut down the pipeline in the meantime. He'll also decide whether the national trade groups get a say in the matter.
