Mahlangu v The State

The two appellants, Mahlangu and Rametsi, were police officers convicted of corruption. The complainant, Makhamba, was a security guard who had shot and killed a suspected robber in self-defence in 1998. Rametsi was the investigating officer of this incident, and Mahlangu usually accompanied him during the investigation. In November 2000, the two police officers visited Makhamba at his workplace and demanded R600 in exchange for withdrawing the case, threatening to arrest him if he did not pay. Makhamba informed his employer who contacted the Anti-Corruption Unit. Makhamba made a payment of R50 on one occasion to Rametsi. The Anti-Corruption Unit set up a trap for 25 January 2001, providing Makhamba with marked R600 in R100 notes. When Mahlangu received the money, he fled when approached by Anti-Corruption Unit officers, and Inspector Mothudi fired a shot at his vehicle but missed. Rametsi was arrested but later released. Mahlangu disappeared for about two years until he was arrested. Both appellants denied soliciting money and claimed they were investigating the firearm used in the shooting incident.

• Whether the State proved the statutory requirements for contravention of section 1(1)(b)(i) or (ii) of the Corruption Act 94 of 1992
• Whether the presiding magistrate impermissibly entered the arena and aligned himself with the State to the prejudice of the appellants
• Whether the legal representative of the first appellant was incompetent and ill-prepared to the extent of rendering the trial unfair
• Whether the trial court properly applied the cautionary rules applicable to single witnesses and evidence of a trap
• Whether the sentence imposed was appropriate

The appeal against both conviction and sentence was dismissed.

The binding principles established are: (1) Under section 1(1)(b)(i) of the Corruption Act 94 of 1992, police officers who demand payment to terminate an investigation (even where no formal charges have been laid) commit corruption, as terminating an investigation constitutes an act "in relation to" the duty with which they have been charged. (2) The test for determining whether a magistrate has impermissibly "entered the arena" is whether the questioning gave the impression to a reasonable person that the magistrate was not impartial and that the accused was not receiving a fair trial; there is a presumption against partiality and the threshold for finding bias is high. (3) A conviction can be based on the evidence of a single witness where such evidence is substantially satisfactory in material respects or where there is corroboration, and such corroboration need not necessarily link the accused directly to the crime. (4) Corruption by police officers is a serious offence warranting substantial custodial sentences, particularly where the offenders show no remorse and persist with baseless denials.

The Court made significant observations about the scourge of corruption in South African society, stating that "corruption has plagued the moral fibre of our society to an extent that to some it is a way of life" and that "there is a very loud outcry from all corners of society against corruption which nowadays seems fashionable." The Court noted that some commentators have stated that corruption is rendering the state dysfunctional. The Court emphasized the role of the courts in implementing legislative penalties and ensuring that justice is not only done but seen to be done. While these observations were not necessary for the decision, they reflect the Court's view on the broader societal context of corruption and the need for deterrent sentencing. The Court also observed that while the magistrate's questioning during Mahlangu's cross-examination was more extensive than necessary and at times showed scepticism, this did not cross the threshold into creating an appearance of bias.

This case is significant for clarifying the interpretation of section 1(1)(b) of the Corruption Act 94 of 1992, particularly in relation to police officers who demand payment to terminate investigations (even where no formal charges have been laid). It confirms that such conduct falls within the scope of corruption as an act "in relation to" their duty. The judgment also provides guidance on the test for judicial bias, reaffirming the high threshold established in S v Basson and the presumption against partiality of judicial officers. The case emphasizes the seriousness with which South African courts view corruption by law enforcement officers and the appropriateness of custodial sentences to reflect society's condemnation of such conduct. It also addresses the application of cautionary rules to single witness testimony and trap evidence in corruption cases.
