The developer of the Dakota Access Pipeline filed a lawsuit Tuesday against Greenpeace and other environmental groups, accusing them of inciting eco-terrorism for their role in campaigning against the pipeline.

Energy Transfer, suing in U.S. District Court in North Dakota, claims the environmental groups committed racketeering and defamation that increased the cost of construction by at least $300 million.

Greenpeace led a "network of putative not-for-profits and rogue eco-terrorist groups" — including Earth First! and BankTrack, also defendants in the suit — with "criminal activity and campaigns of misinformation" against the pipeline, the suit alleges.

Energy Transfer is represented in the lawsuit by by Kasowitz, Benson & Torres LLP, a firm founded by Marc Kasowitz, one of President Trump's personal attorneys.

The suit follows months of protests over the 1,172-mile pipeline, built to deliver Bakken shale oil from North Dakota to Midwestern refineries.

The Standing Rock Sioux tribe and other Native American groups argued a stretch of the pipeline — across the Missouri River in North Dakota near the Standing Rock Sioux's reservation — would taint drinking water and disturb sacred burial and archaeological sites.

Trump revived the completion of the pipeline's construction through an executive order in January, after the Obama administration had ceded to the tribes' concerns and halted the project.

The pipeline began shipping oil in June.

Earthjustice, which represented the Standing Rock Sioux Tribe in litigation against the Army Corps of Engineers to block the pipeline, called Energy Transfer's lawsuit an "unprovoked and malicious attack."

Earthjustice is not named in the suit as a defendant, but is cited numerous times in the suit.

"Representing the Standing Rock Sioux Tribe in their laudable effort to protect their water and sacred lands from the Dakota Access Pipeline is one of Earthjustice's proudest moments," Trip Van Noppen, president of Earthjustice, said in a statement. "This complaint from Energy Transfer Partners is nothing more than an attack on all those who stood up for the Tribe in this historic fight, packaged as a legal claim. It is an unprovoked and malicious attack on those who would use the power of the law and free speech for good."
