Dish Network Corp. Chairman Charles Ergen asked a court to dismiss a lawsuit brought by Philip A. Falcone’s Harbinger Capital Partners LLC against him and an entity that are offering $2.22 billion in cash to buy LightSquared Inc. out of bankruptcy, saying that the suit is an attempt to derail his offer, Bloomberg News reported yesterday. Harbinger sued Ergen and Dish in August, claiming that he’s fraudulently trying to take control of LightSquared, a broadband network services provider, by having an entity that he controls, SP Special Opportunities LLC, buy large amounts of its debt. Ergen and SP said in a motion to dismiss, filed yesterday in bankruptcy court, that they made no “false representations” about the purchases, so there was no fraud.
