Another nasty day in the Carl Icahn vs Lionsgate battle. This time, Icahn has made good on his threat to go to court to overturn the film/TV studio’s recent “scorched earth tactic” that diluted his stock holdings He’s referring to last week’s debt-for-equity swap involving major shareholders Mark Rachesky and John Kornitzer. The lawsuit was filed today in the New York State Supreme Court against Lionsgate, its board of directors, Rachesky, Kornitzer Capital Management and its principal John Kornitzer. Icahn wants an injunction to reverse the deal that bought and converted $100 million in senior notes to reduce Icahn’s stake in Lionsgate from 37.3% to 33.5%. “If allowed to stand, this scheme will insulate the directors and management from having to face a fair election at the upcoming annual meeting of Lionsgate’s shareholders,” Icahn said.

He also filed a Canadian petition in the Supreme Court of British Columbia about the manuever on Friday, while the British Columbia Securities Commission has scheduled a hearing about it on July 28th.

It was Lionsgate’s lastest attempt to thwart his hostile takeover of the mini-major and give it to his son Brett to run. Still pending is Icahn’s latest $6.50 a share tender offer for outstanding shares of the company, and his promise to wage a proxy fight over control of Lionsgate’s board at the September annual meeting.
