Update on Mark Cuban's Court Filing Against Dallas Mavericks New Ownership

Mark Cuban filed a court discovery request about a month ago, as he was upset he wasn't involved in the location of the new Mavericks arena, which was announced to likely be on the site of the former Valley View Mall.

Cuban is claiming that the new Mavericks governor, Patrick Dumont, unlawfully excluded him from business opportunities, and this court discovery was supposed to help prove that.

Furthermore, Cuban claims that Dumont never notified him of the Valley View Mall as a possibility, and that Dumont formed a company called Arena Development Institute for the purchase of the site.

Dumont made his own filing on July 31st, documents first obtained by Front Office Sports, which moved the case from the state court to a business court judge, but Dumont is saying there are no business opportunities to present to Cuban yet because ADI hasn't exercised its right to buy the property yet.

Dumont was also upset that Cuban filed it in the state court to begin with, as it seemed to him to be a way to just get more media coverage, something Cuban has done a lot of since the start of the year.

Cuban has gone on podcasts, letting the world know he regrets who he sold the team to, and a group approached Cuban early in the year in an attempt to buy the team back. Miriam Adelson and Patrick Dumont were not interested.

Mark Cuban Withdraws Filing Against Mavericks

Late on Monday, Cuban withdrew the petition against the Mavs, according to the Dallas Morning News. However, he still wants to be kept in the loop on all things regarding the new arena.

Cuban doesn't quite believe that the Mavericks' interest in Valley View Mall, but he knows the ownership, corporate structure, and affiliate status of ADI, which he confirmed is working with the Dallas Sports Group.

Don't expect this to just go away. Cuban wants to be involved in the process of the new arena and doesn't want to be excluded from potential business opportunities. Cuban still owns 27% of the Mavs, but that can be reduced to 7% because of a clause in the initial contract.

All signs point to that being triggered in the near future.

Cuban is going to be salty about the sale and not being in charge of basketball operations as he wanted to be, but it wasn't in the contract.
