Example Recent Matters

• Prevailed in a second appeal filed by the opponent with the Dallas Court of Appeals. (Bill Siegel and Sim Israeloff handled the trial, Mike Northrup and Sim Israeloff handled the appeal.) Our client, a business that sells health-conscious, hemp-infused food and beverage products, sued its former CEO for secretly issuing company stock to himself and then selling those shares to a third party. After the former CEO refused to respond to discovery, the trial court granted sanctions and rendered a default judgment, which voided the stock and awarded the company the proceeds of the sale of those shares. The amount involved was $3.5 million. 2022 (Click here for more info.)
