QUESTION 1
The Requirement That the Enrichment Must Have Been Sine Causa
The requirement that enrichment must have been sine causa is a crucial element in unjustified
enrichment claims under South African law. The phrase sine causa means “without legal cause” and
ensures that a person who has been enriched at another’s expense is required to restore the benefit
only if there was no valid legal reason for the enrichment. This requirement prevents claims where
enrichment was justified by a contractual obligation, statutory requirement, or a lawful donation. The
burden is on the claimant to demonstrate that the defendant was enriched without a valid cause and
that retaining the benefit would be unjustified.
Legal Framework and Case Law
South African case law has consistently reinforced the sine causa requirement, clarifying when
enrichment is deemed without legal cause and thus actionable.
One of the leading cases is McCarthy Retail Ltd v Shortdistance Carriers CC 2001 (3) SA 482 (SCA), where
the Supreme Court of Appeal held that enrichment is only unjustified if the recipient had no lawful
basis to retain the benefit. The court emphasized that a party cannot claim restitution if the enrichment
resulted from a valid contract, lawful performance of an obligation, or any other legitimate basis. This
decision underscores that sine causa does not exist when a party rightfully receives a benefit under legal
grounds.
In African Diamond Exporters (Pty) Ltd v Barclays Bank 1957 (2) SA 428 (W), the court ruled that a

Similarly, in Meyer v Merchant’s Trust Ltd 1942 AD 244, the court held that where a party mistakenly

enrichment. The judgment reaffirmed that an error in law or fact can lead to sine causa enrichment,
