Even if it can be argued, though wrongly, that the suit ought to have been commenced by means of a judicial review, the Appellants did not raise this at the earliest opportunity at the trial Court. In other words, where an action is commenced by an irregular mode, it is trite law, that a party who took active part in the proceeding without raising a formal complaint or objection to it, cannot later, be heard to complain and pray for the action to be set aside.
