In applications for condonation of non-compliance with Supreme Court Rules, the court must weigh multiple factors including degree of default, explanation, prospects of success, and finality of judgment. Where the explanation for non-compliance is inadequate and the applicant has no reasonable prospects of success on appeal, condonation will be refused. An agreement for the change of ownership of land entered into prior to obtaining subdivision approval under s 39 of the Regional, Town and Country Planning Act is prohibited and invalid, regardless of when the change of ownership is to take place.
