Undoubtedly, the essence of service of originating processes upon a party, a defendant or Respondent as the case may be in administration of justice, cannot be over emphasized. Indeed, the service of origination process on a party is not merely important but fundamental. Indeed, it goes very deeply to the root of the Jurisdictional competence of the Court to adjudicate upon the matter. Thus, failure to serve the adverse party with the necessary originating process invariably renders the proceedings by the Court and any orders predicated thereupon, nullities.
