The interest which will support an application for leave to appeal as interested party must be genuine and legally recognisable interest in respect of a decision which prejudicially affects such a person. And for a person to qualify as a person interested, the applicant must show not only that he is a person having interest in the matter but also that the order or judgement of the Court below which he is seeking leave to appeal against prejudicially affects his interest. In other words, to succeed in the application, the applicants must show that they are persons who are aggrieved or persons against whom decisions have been produced which have wrongfully refused them something or wrongly affected their title to something.
