The judge in the Microsoft antitrust case, Judge Thomas Penfield Jackson, has said he will not issue a final ruling in the case this week.

Jackson has given the US Department of Justice until Monday to respond to Microsoft’s latest court brief, which was filed on Wednesday.

Microsoft would have until next Wednesday (June 7), to respond to that brief, according to Jackson's ruling.

Mixed message It’s unclear what prompted Jackson to set additional deadlines. It is widely expected that Jackson will go along with the Justice Department's plan to split Microsoft into two companies, although last week he expressed interest in a plan to break the company into three entities.

Jackson told the lawyers then that he "was not contemplating any further process" in the trial and he told the government lawyers to file a "clean copy" of their break-up proposal.
