Christine Varney, Assistant Attorney General in charge of the DoJ's Antitrust Division, made the announcement in a speech this morning. In her remarks, Varney stated that the Justice Department would withdraw the findings of a report on Section 2 of the Sherman Act as official DoJ policy on antitrust monopoly enforcement.
Varney went on to say that the notion implicit in the previous policy's hesitance to interfere with companies was that markets would generally correct any monopolies. Pointing to the economic crisis that has dominated the administration's first months in office, Varney stated that "we can no longer rely upon the marketplace alone to ensure that competition and consumers will be protected."
Many people have wondered whether Varney's remarks are aimed at Google, a company that has been coming under increasing antitrust scrutiny lately. Varney said that her statement and the policy shift wasn't directed at any company in particular, but it's worth noting that Varney was a Federal Trade Commissioner specializing in Internet-related competition issues under Bill Clinton.
Kent Walker, Google's General Counsel, might want to start re-reading the Sherman Act.
