In Blasingame v. Krueger, 800 S.W.2d 391, 392 (Tex. App.--Houston 14th Dist. 1990, orig. proceeding), the property owners sought to subpoena various State employees, but the trial court granted a motion to quash filed by the State. 800 S.W.2d at 392. After the trial court granted the motion, the owners filed a mandamus petition. In their response to the petition, the State argued that mandamus relief should be denied because the ability to have a trial de novo after the commissioners' hearing provided the owners with an adequate remedy by appeal. The appellate court agreed and determined that the trial de novo will allow the owners to obtain the information sought through "'regular' discovery in accordance with the rules of civil procedure." Id. at 394.
