The European Commission has restarted its investigation into Oracle's hostile bid against PeopleSoft. Its judgement will now be made in early November.

A spokeswoman for Competition Commissioner Mario Monti said that the inquiry had restarted after Oracle "substantially complied" with the Commission's request for the additional information it needs to examine the merger.

A deadline of 9 November has been set for the decision but, given Monti's desire to conclude the case before he steps down from his post on 1 November, it seems likely that the Commission will announce its decision earlier, possibly on 26 October.

Monti is expected to clear the merger, since investigations which result in deals being blocked generally take longer to conclude than the one-month deadline that the Commission has set. The investigation was put on hold in April after the Commission decided it needed more information, particularly relating to billing data, from Oracle.

Oracle's chances of succeeding with the deal, which at one time seemed highly unlikely, have improved recently. The US Department of Justice said at the start of the month that it won't appeal a federal court ruling rejecting its efforts to block the merger on competition grounds.

Perhaps more significantly, PeopleSoft last week fired its chief executive officer, Craig Conway, who had been adamantly opposed to a merger. PeopleSoft director Steven Goldby testified in court this week that he would be open to discussions with Oracle if the price were right. Oracle must also win support from PeopleSoft's shareholders.
