The binding legal principles established are: (1) Under section 167(3) of the Constitution of Zimbabwe, orders of constitutional invalidity made by the High Court have no force until confirmed by the Constitutional Court; therefore sections 22 and 23 of the Commercial Premises (Rent) Regulations, 1983 remained valid law despite being declared ultra vires in HC 333/21. (2) To defeat an application for summary judgment, a defendant need only establish a bona fide defence with sufficient clarity showing a mere possibility of success or a plausible case that would entitle them to succeed if proved at trial. (3) Where a landlord receives rentals, engages in rental negotiations, and permits a tenant to remain in occupation after lease expiry, this raises plausible defences of tacit relocation and statutory tenancy that are triable issues. (4) In summary judgment applications under Rule 30, a plaintiff must seek the same relief as claimed in the summons and cannot selectively pick and choose portions of relief to pursue, though the court may grant partial judgment under Rule 30(9)(b)(ii). (5) Summary judgment is a drastic procedure meant to balance a plaintiff's interest in timely judgment against the risk of silencing a defendant with a legitimate defence.
