Microsoft has hit back at media giant AOL Time Warner by demanding that it give up more documents in the latest instalment of the ongoing antitrust case.
US District Court Judge Colleen Kollar-Kotelly was told that AOL had not provided the complete set of documents subpoenaed in the case against the software giant.
If the judge accepts Microsoft's arguments, AOL could be prevented from providing evidence at the hearing scheduled for 11 March.
AOL has denied Microsoft's allegations. Earlier this week, the media company took out a lawsuit against Microsoft, seeking damages for its anti-competitive behaviour during the 'browser wars' of the 1990s.
AOL said that the latest legal machinations are in retaliation for the lawsuit.
Microsoft is currently embroiled in a number of legal battles. In November, a settlement was reached with the Department of Justice and nine US states.
A further nine states opposed the settlement, and sought additional penalties. It is this case over which Judge Kollar-Kottely will preside.
