In BQP Industries, Inc. v. State, 694 P.2d 337 (Colo. App. 1984), aff'd., 770 P.2d 1189 (Colo. 1989), ten corporate taxpayers appealed judgments of the trial court entered against them in connection with judicial review of an agency action. Each corporation initiated administrative review by submission of the prescribed form through an officer or director, as agent. But, each corporation subsequently pursued its appeal through an attorney. Nevertheless, the trial court dismissed the appeals on the ground that the applications were void because they had been signed by nonlawyer officers or directors of the corporations. See 694 P.2d at 341. The appellate court disagreed.
