The State v Wellington Mbatha and The State v Nicolaas Marthinus Prinsloo

Two separate criminal prosecutions were referred to the Constitutional Court. Wellington Mbatha was convicted in the Regional Court at Germiston on two counts under the Arms and Ammunition Act 75 of 1969 for unlawful possession of two AK47 rifles and twelve rounds of ammunition, in contravention of sections 32(1)(a) and 32(1)(e). Sentences of eight and two years' imprisonment were imposed to run concurrently. The matter came on appeal to the Witwatersrand Local Division, which referred it to the Constitutional Court. Nicolaas Marthinus Prinsloo was one of 26 accused standing trial in the S v Le Roux and Others case, involving 96 counts arising from bomb explosions before the April 1994 national elections. After the close of the prosecution case, the trial Judge refused discharge on counts 80 to 83 relating to unlawful possession of machine guns, firearms and ammunition. The Judge stated he relied solely on the presumption in section 40(1) of the Act in refusing discharge, and suspended proceedings to refer the constitutional question to the Constitutional Court. Section 40(1) of the Act created a reverse onus presumption: whenever it was proved that an article had been on or in any premises, any person who at that time was on, in, in charge of, present at, or occupying such premises was presumed to have been in possession of that article until the contrary was proved.

• Whether section 40(1) of the Arms and Ammunition Act 75 of 1969 is inconsistent with the right to be presumed innocent under section 25(3)(c) of the Constitution
• Whether the presumption violates the privilege against self-incrimination under section 25(3)(d) of the Constitution
• If section 40(1) infringes constitutional rights, whether the limitation is justifiable under section 33(1) of the Constitution
• Whether the referrals to the Constitutional Court were properly made
• What order should be made regarding the effect of any declaration of invalidity

1. Section 40(1) of the Arms and Ammunition Act 75 of 1969 was declared inconsistent with the Constitution and invalid with effect from the date of judgment (9 February 1996). 2. In terms of section 98(6) of the Constitution, the declaration of invalidity invalidated any application of section 40(1) in any criminal trial in which the verdict was or will be entered after the Constitution came into force, and in which as at the date of judgment either an appeal or review was pending or the time for noting such appeal had not yet expired. 3. The matters of S v Mbatha and S v Prinsloo were referred back to the Witwatersrand Local Division to be dealt with in accordance with the judgment.

A statutory presumption that reverses the onus of proof by requiring an accused person to disprove an essential element of an offence on a balance of probabilities violates the constitutional right to be presumed innocent under section 25(3)(c) of the Constitution, as it permits conviction despite the existence of a reasonable doubt as to guilt. Such a reverse onus provision can only be constitutional if it meets the requirements of section 33(1), namely that the limitation is reasonable, justifiable in an open and democratic society based on freedom and equality, necessary, and does not negate the essential content of the right. The more substantial the inroad into fundamental rights, the more persuasive the grounds of justification must be. A reverse onus provision that is excessively broad in scope, applies without requiring any logical or rational connection between the accused and the prohibited conduct, lacks mechanisms to exclude innocent persons, and imposes a heavy burden on the accused to disprove guilt, is neither reasonable nor justifiable under section 33(1), even where it serves the important objective of combating serious crime. Where the same objective could be achieved through less restrictive means (such as an evidentiary burden rather than a legal burden), the limitation fails the test of justifiability and proportionality.

The Court noted, without deciding, that a right against self-incrimination is implicit in the provisions of section 25(3) of the Constitution, referring to the decision in Ferreira v Levin. However, it was unnecessary to determine the precise scope of this right or its applicability to the facts as the case was decided on the basis of the presumption of innocence alone. The Court suggested that an evidentiary burden (requiring the accused to raise a reasonable doubt rather than to prove innocence on a balance of probabilities) might be more defensible than a reverse legal onus, though it cautioned that such a provision, particularly if broadly framed, would not necessarily be immune from constitutional attack. Such a provision might impact the right to silence, but some limitation on that right might be more defensible than the limitation on the presumption of innocence created by section 40(1). Langa J observed that while the choice of appropriate measures to address social problems is for the legislature, courts cannot accept statutory erosion of constitutional rights without scrutiny. Constitutional recognition of fair trial rights means that statutory presumptions affecting these rights must meet the criteria of section 33(1). The Court emphasized that effective law enforcement should be based on thorough collection of evidence and careful presentation of the prosecution case, not on presumptions that encourage dragnet searches and prosecutions. The Court noted that practical difficulties in prosecution do not justify broad infringements of constitutional rights. The judgment reiterated previous warnings about improper referrals to the Constitutional Court, stating that constitutional issues should only be decided when necessary and that courts should follow the principle of avoiding constitutional issues where cases can be decided on other grounds.

This case is a landmark judgment on the constitutional protection of the presumption of innocence in South African criminal law. It established strict limits on reverse onus provisions that shift the burden of proof to the accused. The judgment affirmed that the presumption of innocence is a fundamental right in an open and democratic society, and that statutory presumptions infringing this right must meet stringent justification requirements under the limitations clause. The case demonstrated the Court's approach to proportionality analysis under section 33(1), requiring that limitations on fundamental rights be precisely tailored to their objectives and that less restrictive means be considered. It rejected the argument that practical difficulties in prosecution or concerns about crime levels alone justify broad infringements of constitutional rights. The judgment has had far-reaching implications for criminal procedure and the validity of numerous statutory presumptions in South African law. It reinforced the principles established in S v Zuma regarding reverse onus provisions and confessions, and formed part of the early constitutional jurisprudence on fair trial rights alongside cases like S v Makwanyane, S v Bhulwana and S v Mhlungu. The case also provided important guidance on proper referrals to the Constitutional Court and the exercise of direct access jurisdiction under section 100(2) of the Constitution.
