A default judgment will be rescinded under Rule 449(1)(a) of the High Court Rules where it was erroneously sought and granted in the absence of a party who had a substantial interest in the matter. To succeed in such an application, the applicant need not demonstrate a bona fide defence but must only establish that the order was erroneously sought and granted in their absence. Where a party is aware that another person claims ownership of property and is in occupation thereof, that person must be cited in eviction proceedings, failing which any judgment obtained will be liable to rescission. The right to be heard, derived from the audi alteram partem rule and the rules of natural justice, requires that a person be given reasonable notice to make representations where another takes action which adversely affects their interests or rights.
