The binding legal principles established are: (1) For leave to appeal, an applicant must demonstrate reasonable prospects of success based on a sound, rational basis - more than mere possibility or arguability is required (following Essop v The State); (2) It is a legal impropriety to cite and sue a deceased person; (3) Section 8 of the Titles Registration and Derelict Lands Act requires strict compliance with notice requirements, including proper description of the property and full citation of parties - failure to comply means the statutory bar does not apply; (4) Section 13 of the Titles Registration and Derelict Lands Act does not preclude rescission of default judgments - title registered under the Act can be annulled or set aside in the same manner as normal transfers; (5) The right to be heard (audi alteram partem) is a fundamental principle that cannot be lightly denied, but where parties fully argue the merits, this right is satisfied; (6) Leave to appeal against interlocutory orders that are not final and dispositive of the matter is limited to ensure efficient administration of justice.
