Mark Cuban is accusing Dallas Mavericks governor Patrick Dumont of freezing him out of business opportunities, according to a newspaper report. The claim is connected to a proposed move involving the NBA team’s location, described in the reporting as a shift of the club out of downtown. Cuban, who is identified in the reports as the team’s former majority owner, alleges that Dumont and other Mavericks owners limit his access to opportunities tied to the arena and related business plans. The articles provided do not specify the evidence Cuban cites, the response from Dumont or the Mavericks organization, or the timing and status of the proposed relocation. They also do not detail whether Cuban’s allegations are part of formal legal action or remain confined to public statements reported by the newspaper. Across the sources, the central point is the same: Cuban is making allegations that he is being excluded from opportunities in connection with the Mavericks’ proposed move and arena-related developments.
