When a judgment cannot have a practical effect on an existing controversy, the case is moot. See Texas Education Agency v. Dallas Independent School District, 797 S.W.2d 367, 369 (Tex.App. 1990, no writ). Ordinarily, we would dismiss the underlying case as well as the appeal. See Texas Education Agency, 797 S.W.2d at 369 (noting general rule that the trial court's judgment must be vacated and cause dismissed when case is moot).
