1. Authority to institute proceedings may be challenged substantively on affidavit and is not impeachable only via rule 7(1) of the Uniform Rules (or Land Court Rules). 2. The grant of a rule nisi with interim relief does not finally determine urgency; a respondent is entitled under rule 34(4)(b) to dispute urgency on the return day, and the court must reconsider it in light of the complete record. 3. Urgency will not be found where the prejudice or harm complained of has existed for a substantial period, the applicant delayed in approaching the court, and substantial redress remains available in due course (self-created urgency). 4. An interdict against "persons unknown" will only be granted where the class is described with sufficient precision to render its membership objectively ascertainable and there is cogent evidence linking that class to the actual or imminent infringement. 5. In the ESTA context, demolition of structures erected without consent or meaningful engagement is not automatic. The court retains full equitable discretion and must apply the justice-and-equity framework mandated by ss 5 and 6(2) of ESTA. Demolition must be justified as proportionate, taking into account: the occupier's dignity, security of tenure, vulnerability, conduct (good or bad faith, response to warnings), and means; the owner's property and management interests; the stage and nature of the structure; the availability of alternative remedies (compensation, regularisation, modification); and the systemic inequality inherent in the owner-occupier relationship on farms. 6. A court should not treat demolition as a routine sequel to unlawfulness in ESTA disputes, especially on urgent truncated papers; less drastic, incremental remedies (such as interim interdicts coupled with directions for engagement and provision for further proceedings) may be more appropriate and just.
