S v Zuma

S v Zuma was the Constitutional Court's first judgment, delivered in 1995. It declared unconstitutional a reverse-onus provision in section 217(1)(b)(ii) of the Criminal Procedure Act 51 of 1977, which required an accused to prove lack of knowledge that goods were stolen, finding it violated the presumption of innocence under the interim Constitution.

Jacob Zuma was charged with offences involving stolen property. The applicable statute placed the burden on the accused to prove he did not know and had no reasonable grounds to believe the goods were stolen. The matter was referred to the Constitutional Court to determine the constitutionality of this reverse-onus provision.

Whether section 217(1)(b)(ii) of the Criminal Procedure Act 51 of 1977, imposing a reverse onus on an accused to prove lack of knowledge, violated the presumption of innocence guaranteed by the interim Constitution.

The Constitutional Court held that section 217(1)(b)(ii) was unconstitutional and invalid. The reverse-onus provision impermissibly infringed the presumption of innocence because it required the accused to prove an element of the offence on a balance of probabilities.

A reverse-onus provision that requires an accused to prove an essential element of an offence violates the constitutionally entrenched presumption of innocence and right to a fair trial.

The Court found that the presumption of innocence is a fundamental right that requires the State to prove all elements of an offence beyond reasonable doubt. While Parliament may create rebuttable presumptions to assist prosecution, requiring an accused to disprove mens rea on a balance of probabilities shifts the core burden impermissibly. The provision could not be saved under the limitations clause of the interim Constitution.

The Court noted that evidentiary presumptions that merely shift a tactical or evidential burden (rather than the legal burden of proof) may be constitutionally permissible, depending on their scope and effect.

This was the Constitutional Court's inaugural judgment, establishing its role as guardian of constitutional rights and signaling that criminal procedure statutes would be scrutinized for compliance with Bill of Rights protections. It remains a foundational precedent on the presumption of innocence and reverse-onus provisions in South African criminal law.
