Overview
- Cuban filed a petition in Dallas County this week that accuses Mavericks governor Patrick Dumont of 'adversarial business practices' and asks a judge to compel disclosure of documents tied to the Valley View site and related entities.
- The filing says Cuban was denied the basketball control he expected after selling majority ownership in 2023 and that he was not notified in time to object to the February 2025 trade of Luka Dončić, which was overseen by then-GM Nico Harrison.
- Cuban asserts his businesses are contractually entitled to take part in the roughly 104-acre Valley View purchase option and he seeks details about the project’s planned development, financing and corporate structure.
- The 2023 sale left Cuban with about a 27% stake and the purchase agreement reportedly allows the Adelson and Dumont families to acquire another 20% of his shares, a clause that shapes the ownership dispute.
- The petition could slow or complicate the Mavericks’ planned move north and its 2031 arena timetable, and both Cuban and the team have declined to comment while the court considers the discovery request.
