Jon Corzine, former chief executive officer of bankrupt MF Global Holdings Ltd., asked that a lawsuit against him by the Commodity Futures Trading Commission be dismissed, Bloomberg News reported today. The CFTC sued Corzine in June for failing to oversee the brokerage company properly while it spiraled toward failure in 2011 as $1.6 billion in customer funds went missing. After “exhaustive investigations lasting 19 months,” the CFTC hasn’t produced evidence to support its claims, Corzine said in a filing yesterday in federal court in New York. The CFTC’s complaint “relies on irrelevant allegations calculated to sully Mr. Corzine’s character, as well as rambling hindsight criticisms of complex management decisions, many of which were made during times of extreme stress,” Corzine said in the filing.
