The Justice Department is probably going to bring an antitrust suit against Google, experts are beginning to say. Yesterday, the department hired former Disney superlawyer Sandy Litvack to take a closer look at Yahoo's deal to outsource search to Google. “They wouldn’t bring in a special counsel unless they were preparing to litigate,” says Sam Miller, the lawyer who defended Microsoft's antitrust trial. Former FCC official Blair Levin agrees . Levin wrote in a Stifel Nicholas research note yesterday that "the hiring of a lawyer with this kind of background is far more rare, and, in our memory, the times when this has happened the Department brought a case." The irony: if the U.S. does win the case against Google, it won't be the search giant which feels the most pain. Yahoo would lose $250 million to $450 million in cash it's counting on raking in.
