The fight between John Malone and Barry Diller is getting brutal. As Diller prepares to spin off several businesses, leaving a company focused on the Oakland-based search engine, Malone's Liberty Media has asked a court to remove Diller from IAC's board and allow Liberty to appoint several board members, in an effort to seize control of the company. Liberty owns 30 percent of IAC, and holds 62 percent of the voting rights, but an agreement allows Diller to vote Liberty's shares, giving him effective control of the company. [WSJ]
