Jurisdiction is very fundamental to adjudication because it goes to the foundational competence of any cause or matter or action before the Court. It is indeed the epicenter of the entire litigation process and thus, without it there can be no validity in any proceedings or resultant judgment or ruling of the Court. Thus, without jurisdiction there can be no competence in the Court to exercise its adjudicatory powers. In such a situation, zealousness to do substantial justice, where there is no competence, is not a virtue. It is simply over zealousness. This is so because “Without jurisdiction, the laborers that is the litigant and counsel on the one hand and the Court on the hand labor in vain”.
