DALLAS -

On Tuesday, the billionaire owner of the Dallas Mavericks and star of "Shark Tank" will be in court as a jury begins hearing his insider trading case.

Three men and seven women will hear the lawsuit in federal district court in Dallas.

They were picked Monday from a pool of 64 prospects.

The Securities and Exchange Commission says Cuban violated insider-trading rules in 2004 by selling his shares in a Canadian Internet company when he learned confidentially about news that would send the shares down.

The government says he avoided $750,000 in losses by dumping his stock.

Cuban's lawyers say he did nothing wrong.
