Dallas Mavericks owner and billionaire entrepreneur Mark Cuban is no stranger to legal disputes. One thorn in Cuban’s side: litigation filed against him in 2009 by Hillwood Investment Properties, a company controlled by H. Ross Perot Jr., son of the two-time presidential candidate of the same name. In its suit, Hillwood accuses the Mavs majority owner of mismanaging the team and certain real estate assets. (Perot, who owns a 5 percent stake in the team, sold Cuban a controlling stake in the Mavs in 2000 for $285 million.)

Now, just a few weeks after the Mavs won their first NBA championship by beating the Miami Heat, Cuban’s lawyers from Fish & Richardson filed “World Champion Dallas Mavericks and Radical Mavericks Management’s Motion for Summary Judgment,” which lets Perot know just how wrong they think he is about Cuban’s handling of the team.
