Bamba v S

The appellant, Constable Thembani Bamba, was charged with the murder of Ludwe Golotile, a 23-year-old man, on 20 January 2007. The appellant was on crime prevention patrol duty with other police officers in Samora Machel, Nyanga township. They encountered a group of people who scattered into shacks and threw rocks at police. After people dispersed, a gunshot was heard. The deceased was found shot and died at the scene. A bullet head fell from the deceased's shirt. All police officers on duty had their firearms and magazines confiscated. The Independent Crime Directorate investigator, Booi, received exhibits including a bullet head and cartridge from the deceased's brother and confiscated firearms. These were sent for ballistic examination. The ballistic report concluded the projectile and cartridge matched the appellant's firearm. The appellant was convicted of murder in the Regional Court and sentenced to 10 years' imprisonment. The Western Cape High Court dismissed his appeal against conviction but altered the finding from dolus directus to dolus eventualis.

• Whether the State proved beyond reasonable doubt that the appellant shot and killed the deceased
• Whether the chain of custody and preservation of ballistic evidence was properly established
• Whether the ballistic evidence could be relied upon to link the exhibits found at the scene to those tested at the laboratory
• Whether the inference that the appellant fired the fatal shot was the only reasonable inference from the proven facts
• Whether the court a quo had jurisdiction to grant leave to appeal after the commencement of the Superior Courts Act

1. Special leave to appeal to the Supreme Court of Appeal against conviction was granted. 2. The appeal was upheld. 3. The order of the Western Cape High Court was set aside and substituted with an order upholding the appeal and setting aside the trial court's order, with the appellant found not guilty and discharged.

The binding legal principles established are: (1) The prosecution must prove beyond reasonable doubt the factual link between exhibits allegedly collected at a crime scene and those tested at a forensic laboratory - material discrepancies in exhibit reference numbers and contradictory evidence about preservation and conveyance of exhibits render such evidence unreliable. (2) In circumstantial evidence cases, applying R v Blom, the inference sought to be drawn must be consistent with all proved facts and must exclude every other reasonable inference - if other reasonable inferences exist, there is doubt about the correctness of the inference. (3) The utmost care must be taken by police, particularly investigating officers, in the recovery, storing, recording and conveying of exhibits for forensic examination. (4) The State has a duty to ensure that requisite evidence proving the integrity of the chain of custody is properly led at trial. (5) Where critical evidence is unreliable and the accused's version is reasonably possibly true, the accused must be afforded the benefit of reasonable doubt and acquitted.

The court noted that the Western Cape High Court did not possess jurisdiction to grant leave to appeal on 28 August 2013 because the Superior Courts Act 10 of 2013 had repealed the Supreme Court Act 59 of 1959 as at 23 August 2013, and special leave from the Supreme Court of Appeal was required. The court also observed that what the case illustrates is the need for utmost care by police in handling ballistic exhibits to avoid the material discrepancies seen throughout the trial court proceedings, and that the State must ensure requisite evidence to prove chain of custody requirements is properly led.

This case is significant in South African criminal law for establishing strict standards regarding the chain of custody and preservation of forensic evidence, particularly ballistic exhibits. It emphasizes that the prosecution has a duty to prove the integrity of the chain of evidence from recovery through testing, and that material discrepancies in exhibit numbering and handling can fatally undermine the reliability of forensic evidence. The judgment reinforces the principle that the State must prove its case beyond reasonable doubt, and where evidence critical to conviction (such as ballistic evidence) is unreliable due to procedural failures, and the accused's version is reasonably possibly true, the accused must receive the benefit of the doubt. The case serves as a warning to investigating officers about the utmost care required in recovering, storing, recording and conveying exhibits for forensic examination.
