On 3 August 1991, the respondent (plaintiff) was severely injured as a passenger in a motor vehicle collision. On 3 August 1993, her attorneys (MNM) lodged a claim form with Santam Insurance Company (the then statutory third party insurer), handled by Mr Van Schalkwyk. The claim was not disputed on merits (negligence of the insured driver Petrus Lekgwabe was effectively conceded), but Van Schalkwyk requested further information to quantify the claim, particularly regarding disability grants. Communication was difficult as the plaintiff lived in a remote area of the Northern Province. The summons was only served in February 1997, over five and a half years after the collision. Under Article 57 of the Multilateral Motor Vehicle Accidents Fund Act 93 of 1989, the prescriptive period was five years from when the claim arose (provided the claim form was lodged within three years). The claim therefore prescribed on 2 August 1996. Van Schalkwyk only realized prescription had occurred when he received information about the disability grant in September 1996, and immediately notified MNM. The Fund (statutory successor to Santam) raised prescription as a special plea. The plaintiff argued: (1) implied waiver; (2) estoppel; (3) interruption of prescription by acknowledgment of liability under s 14 of the Prescription Act; and (4) constitutional unfairness under ss 33 and 34 of the Constitution.
