Section 14 of the High Court Act requires an applicant to demonstrate a direct and substantial interest in an existing, future, or contingent right as a jurisdictional prerequisite for declaratory relief. Even where this threshold is met, the court retains discretion to refuse relief. Declaratory relief under s 14 cannot be used as a substitute for review, rescission, or appeal procedures, nor can it be used to indirectly attack, neutralize, or undermine extant court orders. Where court orders have already determined the legal position regarding property rights and ownership, an application seeking a declaration inconsistent with those orders is an impermissible collateral attack and constitutes abuse of process. The Henderson principle bars parties from raising in later proceedings matters which were, or with reasonable diligence could and should have been, raised earlier. Transfer of immovable property in Zimbabwe is effected by registration, and a court declaration cannot serve as a substitute for deeds registration. Where an applicant's case fundamentally conflicts with extant court orders and authoritative instruments of record (such as a Sheriff's affidavit), the applicant cannot establish the requisite interest for declaratory relief.
