Philip Falcone's Harbinger Capital Partners is again suing Dish Network Corp. DISH +0.78% and Chairman Charlie Ergen, this time under the federal racketeering statute. Harbinger is suing both Mr. Ergen and Dish for at least $1.5 billion, saying Mr. Ergen violated the Racketeer Influenced and Corrupt Organizations Act when he acquired the debt of LightSquared—the wireless venture controlled by Harbinger—as Dish was making a bid for the company. Harbinger says Mr. Ergen's purchases caused it to lose money and control of the LightSquared board. Mr. Falcone and other Harbinger officials resigned from the board as part of negotiations for a bankruptcy court restructuring. "Ergen and his fellow RICO Enterprise members pursued their abusive scheme through wire, mail and bankruptcy fraud, abuse of process, tortious interference with contract, and obstruction of justice," Harbinger lawyers said in a filing with U.S. District Court in Colorado. Under RICO, originally designed to prosecute organized crime, parties can seek more damages than is typically allowed. [WSJ, related]
