In essence therefore, initiating an action on a wrong procedure robs the court of its jurisdiction to adjudicate over such matter. The issue of jurisdiction of a court to adjudicate over a matter before it is a threshold issue that goes to the root or foundation of adjudication. This stems from the trite position of the law, that once it is discovered that a court has no jurisdiction to adjudicate over a matter, any decision/proceedings emanating from such a court regarding that matter, no matter how well rendered or conducted, is a nullity.
