Last week Microsoft settled its only outstanding anti-trust case, a class action lawsuit brought in Iowa.

Comes vs Microsoft was resolved seven weeks into trial, and the terms of the settlement will not be revealed until April.

However, the settlement has already had one fortunate outcome for Redmond. The plaintiffs' evidence, which constitutes the largest and most comprehensive archive of Microsoft's dirty tricks ever amassed, has disappeared from the web.

Plaintiffs maintained a website at iowaconsumercase.org, which included daily media updates, full transcripts of the previous day's proceedings, and an archive of some 2,000 exhibits of alleged misdeeds going back to the 1980s.

The website is now password-protected. Microsoft's own archive of exhibits and transcripts has similarly disappeared. Microsoft maintains a comprehensive record of its antitrust proceedings, making Comes a notable absence.

One of the centerpieces of the Iowa class action lawsuit is Microsoft's anti-competitive tactics against DR-DOS and Novell. Caldera, which acquired the rights to DR-DOS in lawsuit in 1996 and filed suit against Microsoft the same year, and settled in early 2000 before trial began.

Readers will recall how 937 boxes of material from the Caldera lawsuit were destroyed in 2003 - apparently at the request of SCO.

Neither of the press contacts for the Iowa Case had returned our calls at time of writing; the office number for media enquiries in the case has been delisted.

Parts of the evidence are still available via Google's cache, however the crawler reached only a small fraction, around 10 per cent, of the exhibits in the Iowa archive, and Google's notoriously sloppy OCR software is so poor that the HTML version is barely comprehensible, as this sample illustrates:

Not very useful to scholars, lawyers or anyone else. ®

Bootnote: Microsoft's eagerness to destroy evidence in the Burst case, suggests Mark ("Robert X Cringely") Stephens, [pt1 - pt2] could lead to perjury prosecutions. As he recounts here, while Redmond lawyers were protesting that they couldn't find deleted emails requested by the court, the emails were sitting in boxes on campus. Oops. ®
