App.---Austin 1996, writ denied), the Court acknowledged the use of discovery in another case involving allegations of procedural irregularity in a suit for judicial review of the Department's order granting a permit application. See 940 S.W.2d at 676-77. The Court rejected the applicant's claim that the district court had erred in allowing certain witnesses to testify at the district court hearing because the witnesses were not sufficiently identified in discovery responses.
