The binding legal principles established are: (1) A settlement agreement limited to the negligence of an insured driver does not settle causation or the existence and extent of injuries and consequential loss; (2) An order for the furnishing of an undertaking in terms of s 17(4)(a) of the Road Accident Fund Act does not, in the absence of a specific determination or agreement, resolve the question of what injuries were caused by the collision or whether such injuries gave rise to compensable loss; (3) In delictual claims, all elements must be independently proved: wrongfulness, negligence, causation (factual and legal), harm, and quantification of loss; (4) In undefended actions for unliquidated damages, the default position is that viva voce evidence must be led - expert reports without confirming affidavits and without viva voce evidence do not constitute admissible and sufficient proof; (5) The failure to present any properly admissible evidence at a default hearing is fatal to a claim and dispositive of the matter.
