Microsoft's Antitrust Case Deepens as Tribunal Demands Documents

A multi-million dollar antitrust case against Microsoft has taken a significant turn in favor of ValueLicensing, a secondhand software reseller. The UK Competition Appeal Tribunal is demanding documents from past and present Microsoft executives related to the company's alleged abuse of market dominance.

The central issue revolves around an internal 'Second-Hand Software' presentation, referred to as a 'known adverse document.' The specific content has not been made public, but Microsoft must explain why it wasn't disclosed earlier. Additionally, 11 previously confidential documents relevant to the case have had their designation lifted.

ValueLicensing alleges that Microsoft stifled the supply of pre-owned software licenses in the UK and European Economic Area by entering into agreements with customers. This allegedly prevented them from reselling their perpetual licenses in exchange for subscription service discounts, leading to higher prices and less choice for customers.
