The oil industry has scored a major win in the fight to build the Dakota Access Pipeline, which would go from North Dakota through South Dakota and Iowa into Illinois.

A North Dakota federal court sided with Dakota Access LLC, the company behind the pipeline, yesterday (August 17) by ordering protestors with the Standing Rock Sioux Tribe to stop blocking the pipeline’s construction, according to ThinkProgress. The company filed a lawsuit to obtain the restraining order against the tribal chairman and protestors just days ago after they suspended work.

The Oceti Sakowin, the proper name for the Sioux, claim that the pipeline puts their tribal lands and waters at risk. It is proposed to cross Lake Oahe and the Missouri River less than a half-mile from their territory.

In response to the restraining order, Chairman David Archambault II called on the White House for action, according to Indian Country Today Media Network, noting the president offered help when he visited the tribe in 2014.

The Dakota Access Pipeline, also called the Bakken Pipeline, is nearly as long and wide as the controversial Keystone XL Pipeline, but it would not have the capacity to ship as many barrels of oil a day.

The tribe’s efforts have received widespread support from celebrities like Leonardo DiCaprio, Rosario Dawson and Shailene Woodley.
