Woodstock 50, LLC has filed for a court order against the investors who recently pulled their financial support of the festival, TMZ reports and Pitchfork can confirm. In the verified petition, filed yesterday (May 8) in a New York court, a lawyer for Woodstock 50 argues that Dentsu violated an agreement with Woodstock 50 and is asking for an order that would see “Dentsu cease all communications relating to the Festival,” return $17.8 million to Woodstock’s bank account, award financial relief to Woodstock, and more.

“W50 [Woodstock 50, LLC] was blindsided by Dentsu’s announcement, and shocked and outraged that Dentsu claimed the right to unilaterally cancel the Festival—an action that is expressly barred by its Agreement with W50,” the lawyer writes. “Dentsu’s sabotage did not stop with its unauthorized and improper cancellation announcement. Dentsu also pillaged the Festival bank account on its way out, taking all of the $17.8 million in the account earmarked for Festival production costs.”

The Financing and Production Agreement between Amplifi Live, LLC and Woodstock 50, LLC (filed as an exhibit in the case and viewed by Pitchfork) states, “Any decision to cancel the Festival shall be jointly made in writing by the Parties.” In addition, the Agreement includes the following passage:

Neither Party shall make any public announcement confirming musical or other performing talent at the Festival, or any other public announcement that may restrict the ability of the Parties to obtain refunds from musical or other performing talent, until the Parties have mutually agreed in writing to make such type of public announcement for the first time (the “Initial Festival Announcement”).

Pitchfork has contacted representatives and attorneys for Woodstock 50, LLC, as well as Dentsu.

The allegations in the verified petition reflect claims that Woodstock co-creator Michael Lang made in a letter to Dentsu earlier this week. In his letter, Lang wrote that Dentsu “illegally swept approximately $17 million from the festival bank account.” In addition, he claimed that the company was responsible for blocking ticket sales and that Dentsu also suggested to performers, the venue, and vendors that they should cut ties with Lang.

Update (05/09 2:38 p.m. Eastern): A representative for Woodstock 50 says that a hearing regarding the festival organizers’ verified petition has been scheduled for Monday, May 13, and that a gag order has been handed down to Dentsu by the court. The full statement reads:

On Wednesday, May 8th, Woodstock 50 made an emergency application to the Supreme Court of New York State seeking a Temporary Restraining Order against Dentsu and Amplifi Live to prevent those parties from causing further damage to the Woodstock 50 Festival that will be held this August. The court today issued an order that Dentsu and Amplifi Live "shall cease all communications relating to the Festival, including with the media, and Festival stakeholders, including state and county officials, venue operators, local vendors, community representatives, insurers, producers, and talent agencies and performers" pending a hearing on all of the issues raised by Woodstock 50—including Dentsu and Amplifi Live's wrongful misappropriation of nearly $18 million in Festival funds—that will be held on Monday.

Woodstock 50’s previously announced lineup includes JAY-Z, the Killers, Chance the Rapper, Miley Cyrus, and the Raconteurs, among others.
