The judge hearing the Microsoft Corp versus the Department of Justice anti-trust case left all sides none the wiser as to which way he is leaning, following a two hour hearing on Friday. Judge Thomas Jackson will issue a written ruling as to whether the case should be extended to include a discovery period for Microsoft to gather evidence from Justice, which wants to get the case wrapped up by February when Microsoft plans to have personal computer manufacturers installing Internet Explorer 4.0. There is no time frame for when the ruling will be made. In October Justice accused Microsoft of reneging on an earlier consent decree by integrating Internet Explorer with Windows 95 and forcing personal computer manufacturers to license all or nothing. Microsoft says IE is an integrated product with the operating system and justice knew and approved of its plans all along.
