The SEC charged in a civil lawsuit that Cuban violated insider-trading rules in 2004 by selling his shares in a Canadian Internet company after learning confidentially about news that would send the shares down. One woman picked for the jury remembered seeing Cuban several years ago on "Dancing With the Stars." A jury is set to decide the government's lawsuit charging billionaire and Dallas Mavericks owner Mark Cuban with insider trading. Much of the questioning by lawyers for both sides dealt with what jurors knew about confidentiality agreements and whether they had seen Cuban on ABC's "Shark Tank." After Fitzwater dismissed the SEC lawsuit in 2009, an appeals court overturned his decision and sent the case back.
