Road Accident Fund v Mongalo, M E; Nkabinde, Palesa Joyce v Road Accident Fund

Two consolidated appeals involving claims by plaintiffs who alleged they were customary union widows of deceased road accident victims and claimed damages for loss of support from the Road Accident Fund (RAF). In both cases, the RAF admitted liability for damages resulting from the deaths, but contested whether the plaintiffs were partners in customary unions with the deceased at the time of the collisions. Both plaintiffs produced certificates issued by Commissioners under the Black Laws Amendment Act 76 of 1963, which under s 31(2A) are stated to be "conclusive proof" of the existence of customary unions. The RAF sought to lead evidence impugning the certificates on grounds of fraud. In Mongalo, Lewis J ruled the RAF could not lead such evidence. In Nkabinde, Snyders J allowed evidence of fraud, found the certificate was fraudulently procured, and granted absolution from the instance with costs.

• Whether a certificate under s 31 of the Black Laws Amendment Act 76 of 1963 constituting 'conclusive proof' of a customary union can be impugned by evidence of fraud
• Whether s 31 of the 1963 Act had been superseded by s 4 of the Recognition of Customary Marriages Act 120 of 1998
• In Nkabinde, whether the evidence established fraud in the procurement of the customary union certificate
• The meaning and scope of 'conclusive proof' in statutory provisions

In Mongalo: Appeal succeeded with costs including two counsel. The ruling of Lewis J was set aside and replaced with an order that the defendant is entitled to lead evidence impugning the certificate on grounds of fraud, with the plaintiff to pay costs of the argument on the ruling. In Nkabinde: Appeal succeeded with costs. The judgment granting absolution from the instance was set aside and replaced with a judgment that the defendant (RAF) is liable for any damages the plaintiff may prove, with the defendant to pay costs of the action.

A statutory provision that a certificate constitutes 'conclusive proof' of a fact does not immunize that certificate from being challenged on the basis that it was obtained by fraud. The principle that any document can be upset on grounds of fraud applies universally and is not excluded by statutory language designating a document as 'conclusive proof'. 'Conclusive proof' means the certificate is ordinarily determinative and excludes evidence to the contrary in the absence of fraud, but it does not mean the certificate is unimpeachable where fraud in its procurement is proved. A party seeking to impugn a certificate on grounds of fraud bears the burden of proving fraud on the balance of probabilities, though such evidence must be carefully scrutinized given the seriousness of allegations of dishonest conduct.

The Court observed that the statements in S v Moroney regarding the meaning of 'conclusive proof' (that it connotes proof which excludes 'all countervailing evidence') were obiter dicta not necessary to decide the meaning of 'sufficient proof' in that case, and were erroneously over-broad insofar as they might be read to exclude evidence of fraud. The Court noted that powerful policy reasons underlie the principle that fraud vitiates documents: deliberate deceit in procurement must taint the document's entire subsequent existence, and the law cannot permit propagation of the fruits of dishonesty. The Court indicated it was unnecessary to decide difficult questions about when a customary union comes into existence and how it is evidenced, given the finding that fraud was not proved. The judgment also commented on the implications of fraudulently obtained certificates for genuine customary union partners who would have to share damages under s 31(5), noting the legislature could not have intended to license such injustice.

This case establishes important principles regarding the interpretation of 'conclusive proof' in South African statutory provisions, particularly in the context of customary unions. It affirms the fundamental principle that fraud vitiates all documents, regardless of statutory language describing them as 'conclusive'. The judgment is significant for customary law claims, particularly Road Accident Fund matters involving customary union partners. It clarifies that s 31 of the Black Laws Amendment Act 76 of 1963 was not superseded by the Recognition of Customary Marriages Act 120 of 1998. The case also provides guidance on the standard of proof required when alleging fraud, emphasizing that courts must carefully scrutinize such allegations. The decision disapproves dicta in S v Moroney and Finlay v Kutoane, while approving Registrar of Asiatics v Salajee and Hlela v Commercial Union Assurance, thereby settling conflicting lines of authority.
