Overview
- Mark Cuban has filed a Texas Rule 202 petition in Dallas County accusing Mavericks governor Patrick Dumont of freezing him out of business opportunities and seeking internal records about the Valley View arena project.
- Cuban’s filing says his companies are contractually entitled to participate as equity investors in the Valley View deal and asks the court to compel an entity tied to Dumont to produce purchase contracts, financing papers and corporate records.
- The petition reiterates Cuban’s claim that a verbal handshake gave him control of basketball operations and says he was excluded from key decisions, citing the February 2025 trade of Luka Dončić as an example of being shut out.
- Cuban retained roughly 27% ownership after the 2023 sale, and the original purchase agreement reportedly allows the Adelson and Dumont families to buy an additional 20% of his stake, a clause that could limit his leverage.
- The Mavericks and Cuban have declined substantive public comment, and legal experts say the pre-suit discovery move could presage formal litigation that might complicate or delay the team’s planned move to a 104-acre Valley View site targeted to open by 2031.
