Administration Plans to Strengthen Antitrust Rules

President Obama's top antitrust official this week plans to restore an aggressive enforcement policy against corporations that use their market dominance to elbow out competitors or to keep them from gaining market share. The new enforcement policy would reverse the Bush administration's approach, which strongly favored defendants against antitrust claims. It would restore a policy that led to the landmark antitrust lawsuits against Microsoft and Intel in the 1990s. The head of the Justice Department's antitrust division, Christine A. Varney, is to announce the policy reversal in a speech she will give on Monday before the Center for American Progress, a liberal policy research organization. She will deliver the same speech on Tuesday to the United States Chamber of Commerce. In the speeches, Ms. Varney is expected to explicitly warn judges and litigants in antitrust lawsuits not involving the government to ignore the Bush administration's policies, which were formally outlined in a report by the Justice Department last year. The report applied legal standards that made it difficult to bring new cases involving monopoly and predatory practices.
