Patrick Dumont and Mark Cuban escalate legal dispute over Mavericks arena

Patrick Dumont challenges Mark Cuban's claims regarding a potential new Mavericks arena site in a legal dispute. Cuban filed a petition in Texas state court alleging that Dumont unlawfully excluded him from discussions about a property option at the former Valley View Mall. Dumont contends Cuban is seeking involvement in a deal that does not yet exist and claims that his business formation was compliant with legal standards. A Texas business court judge recently denied a request from Cuban's team to move the case back to state court. Dumont argues the matter should be privately arbitrated based on their partnership agreement. Cuban has previously expressed regret about selling his majority stake in the team to Dumont and the Adelson family in 2023.
