The developer of the Dakota Access oil pipeline is going after the environmental group Greenpeace in state court in North Dakota, after a judge tossed the company's $1 billion racketeering claim out of federal court.

Texas-based Energy Transfer Partners on Thursday sued Greenpeace and several activists it also had targeted in the federal lawsuit that U.S. District Judge Billy Roy Wilson dismissed on Feb. 14. Wilson said he found no evidence of a coordinated criminal enterprise that had worked to undermine ETP and its pipeline project.

ETP had made claims under the federal Racketeer Influenced and Corrupt Organizations Act and also under North Dakota laws. Wilson did not address the merits of the state claims.

ETP seeks "millions of dollars of damages" in the state lawsuit, which makes similar claims to its federal lawsuit — that Greenpeace and activists conspired to use illegal and violent means such as arson and harassment to disrupt pipeline construction and damage the company, all the while using the highly publicized and prolonged protest to enrich themselves through donations.

"Defendants thus advanced their extremist agenda ... through means far outside the bounds of democratic political action, protest, and peaceful, legally protected expression of dissent," company attorney Lawrence Bender wrote in the complaint.

Greenpeace on Friday had not yet been served with the lawsuit and declined to comment on its specifics. However, Greenpeace attorney Deepa Padmanabha said ETP "is clearly still trying to bully Greenpeace through the legal system."

"We are confident that this latest attempt to silence peaceful advocacy will receive the same fate as the last meritless attack," he said.

Groups and American Indian tribes who feared environmental harm from the pipeline staged large protests that resulted in 761 arrests in southern North Dakota over a six-month span beginning in late 2016. ETP maintains the pipeline is safe. It began moving North Dakota oil through South Dakota and Iowa to a shipping point in Illinois in June 2017.
