A London tribunal has ruled that Microsoft must face a large-scale lawsuit accusing the company of overcharging thousands of British businesses for using its Windows Server software on competing cloud platforms, according to Reuters.

The case has been brought by competition lawyer Maria Luisa Stasi on behalf of nearly 60,000 businesses that rely on Windows Server while operating on cloud services offered by rivals such as Amazon, Google, and Alibaba. The claim could be worth as much as 2.1 billion pounds ($2.8 billion), per Reuters.

Lawyers representing the claimants argued during a hearing last year that Microsoft imposed higher wholesale licensing fees for Windows Server when it was used outside its own Azure cloud platform. These higher costs were then passed on to customers, effectively making Azure a more financially attractive option compared to competing services like Amazon Web Services and Google Cloud.
