Carl Roberts v Additional Magistrate for the District of Johannesburg, Mr Van Den Berg and The Attorney General of the Witwatersrand

The appellant was convicted in a magistrate's court of assault with intent to do grievous bodily harm and sentenced to a fine and suspended imprisonment. The case arose from two incidents at a steakhouse parking lot on 30 November 1994. In the first incident, after an exchange of abuse, the complainant struck the appellant with a hacksaw. The prosecution claimed it was a single blow in self-defense, while the appellant testified he was chased and struck multiple times from behind, resulting in eight or nine cuts on his head and back. In the second incident, the complainant was assaulted and lost sight in his right eye. The magistrate accepted the complainant's evidence and convicted the appellant. After conviction, the appellant changed attorneys and counsel. At the sentencing hearing, counsel called a doctor who testified about eight fresh abrasions on the appellant's body. The magistrate displayed displeasure, switched off the recording device, exclaimed 'that is it' and rushed out of court. He refused to allow the complainant to be recalled, rejected admission of the complainant's police statement after a private discussion with the prosecutor, and denied a recusal application without reasons.

• Whether irregularities occurring after conviction vitiated only the sentence or the entire trial proceedings
• Whether the magistrate's post-conviction conduct created an appearance of bias requiring recusal
• What is the proper test for apparent judicial bias in South African law
• Whether suspected bias that manifests after conviction can taint the conviction itself

The appeal was allowed. The order of the Court a quo was set aside and substituted with an order that: (1) The application for review succeeds and the conviction and sentence are set aside; (2) By agreement, no order is made as to costs.

The binding legal principles established are: (1) The test for apparent judicial bias in South African law consists of four elements: (a) there must be a suspicion that the judicial officer might (not would) be biased; (b) the suspicion must be that of a reasonable person in the position of the accused or litigant; (c) the suspicion must be based on reasonable grounds; and (d) the suspicion is one which the reasonable person would (not merely might) have. (2) Not only actual bias but also the appearance of bias disqualifies a judicial officer, and continuing to preside after recusal should have occurred renders the further proceedings a nullity. (3) Where a judicial officer's conduct after conviction creates a reasonable suspicion of bias, the entire trial may be vitiated if a reasonable person in the accused's position would think the suspected bias might have motivated the conviction. (4) Private communication between a judicial officer and one party in the absence of the other party is a fundamental irregularity that vitiates proceedings. (5) The South African 'reasonable suspicion' test for bias is to be preferred over the English 'real danger' test as it better accords with constitutional values and assesses bias from the perspective of the accused rather than the reviewing court.

Howie JA made significant obiter observations comparing the South African 'reasonable suspicion' test with the English 'real danger' test established in R v Gough. He observed that there is an important distinction between assessing the appearance of bias through the eyes of a trained judicial officer versus a reasonable person, even when both possess the same knowledge. The Court noted that the real danger test depends on 'the view from the Bench' while the reasonable suspicion test depends on 'the view from the dock', and that the former may be more likely to excuse inappropriate judicial behavior that would nonetheless create a reasonable impression of bias. The Court commented that the reasonable suspicion test 'accords better with the provisions and spirit of the Constitution' and 'is more conducive to acceptance by the accused or the litigants that proceedings will in the end be fair', with a 'salutary' constraining effect on those presiding over trials. The judgment also made obiter comments about the inadequacy of the trial court's credibility findings and treatment of the medical evidence, noting the 'remarkable' failure of the original defense attorney to put the medical report to prosecution witnesses or call the doctor at trial.

This case is highly significant in South African law for comprehensively clarifying and finalizing the test for apparent judicial bias. It established the four-part test for recusal based on appearance of bias, preferring 'would have' rather than 'might have' for the fourth element to make the test more decisive. The judgment clarified that the South African test assesses bias from the perspective of a reasonable person in the position of the accused ('from the dock'), rejecting the English 'real danger' test which assesses from the perspective of the reviewing court ('from the Bench'). The case establishes that apparent bias occurring after conviction can vitiate the entire trial where a reasonable person would suspect the bias might have existed throughout and influenced the conviction. It reinforces fundamental principles that judicial proceedings must be conducted in public, that judges must not communicate with one party in the absence of the other, and that justice must not only be done but be seen to be done. The judgment provides important protection for the right to a fair trial under section 25(3) of the Interim Constitution (and subsequently the final Constitution).
