The environmental activist group Greenpeace is fighting to defend itself against a $300 million dollar lawsuit in federal court, accused of organizing violent protests to delay the Dakota Access Pipeline (DAPL).

The protests near the Standing Rock Sioux reservation began in April 2016 as thousands of protestors and environmental activists gathered to oppose the DAPL which transports oil from North Dakota to Illinois.

The pipeline was ultimately completed but not before the protests had escalated into arrests for violence, obstruction, and trespassing that  Energy Transfer, the Dallas-based company behind the DAPL, says cost them millions of dollars in financial losses.

After the protests, workers found vandalized equipment, abandoned pets and 21 million pounds of garbage that cost $1.1 million to clean up.

Attorneys for Energy Transfer have argued that Greenpeace played a key role in coordinating and fundraising off the protests and the company is suing Netherlands-based Greenpeace International, U.S. affiliate Greenpeace USA and organization’s financier the Greenpeace Fund for $300 million dollars.

The Energy Transfer legal team has sought to highlight connections between Greenpeace and the DAPL protestors through payments made to activist groups like the Red Warrior Camp and the Indigenous Peoples Power Project.

Among the evidence shown to jurors thus far in court is an Aug 30, 2016 email from IP3 founding member Nick Tilsen to Greenpeace employee Cy Waggoner, who is an IP3 board member, stating, “Our ability to provide this level of training would not be possible without financial support from Greenpeace.”

The Washington Post reports that protestors received a “rapid response grant” from Greenpeace as well as other materials like lockboxes to chain themselves to equipment and payments to cover the trainers’ costs of food and travel.

Energy Transfer Partners CEO Kelcy Warren says Greenpeace raised millions of dollars off the protests by spreading “lies” about the pipeline encroaching on the Standing Rock reservation when the actual pipeline is never closer than half a mile from the reservation’s boundary.

Greenpeace had asked the North Dakota Supreme Court to move the trial to Fargo from Morton County District Court in Mandan, the community most affected by the months-long protests, but that request was denied.

Supporters of Greenpeace are expressing concern that a $300 million judgment could bankrupt Greenpeace USA and have a stifling effect on free speech by other activist groups.

Mark Morano, the publisher of Climate Depot, remains skeptical of claims that a victory by Energy Transfer would force Greenpeace USA to go out of business, calling the dire predictions, “another fundraising appeal.”

Greenpeace is expected to rest its case on Friday.
