Mambo v The State

Three appellants (Mambo, Moroane and Hlako) had been arrested on armed robbery and related charges arising from a carjacking incident in December 1996 and January 1997. They remained in custody for approximately one and a half years. On 19 May 1998, while appearing in the Pretoria Magistrate's Court, after their case was postponed and bail was denied or unaffordable, they were being returned to the holding cell adjacent to the court. As the court orderly unlocked the gate of the holding cell, he was overpowered, disarmed and fatally wounded by a gunshot from his own firearm. The three appellants then escaped from the holding cell, though they were subsequently recaptured. The only witness to the incident was another awaiting-trial prisoner, Abel Makhubela, who was already in the cell. According to Makhubela, appellant 1 gripped the orderly around the neck, appellant 2 grabbed his legs, and appellant 3 seized the firearm from the orderly's holster. Appellant 1 allegedly said 'skiet' (shoot), whereupon appellant 3 cocked the weapon and fired, killing the orderly and injuring appellant 1's arm. The appellants presented different versions denying their involvement or intent.

• Whether the appellants acted with common purpose in murdering the court orderly
• Whether appellant 2 could be convicted of murder on the basis of common purpose when the murder was not reasonably foreseeable to him
• Whether substantial and compelling circumstances existed to justify departure from the prescribed minimum sentences under the Criminal Law Amendment Act 105 of 1997
• The application of mandatory minimum sentencing provisions under sections 51(1) and 51(2) of the Criminal Law Amendment Act 105 of 1997

The appeal was partially successful. For appellants 1 and 3: convictions for murder, escaping from custody confirmed; sentences for murder (life imprisonment) and escape confirmed; robbery convictions confirmed but life imprisonment sentences set aside and replaced with 15 years' imprisonment; appellant 3's convictions and sentences for unlawful possession of firearm and ammunition confirmed. For appellant 2: conviction and sentence for murder set aside; conviction and sentence for escaping from custody (5 years) confirmed; conviction for robbery confirmed but life imprisonment set aside and replaced with 10 years' imprisonment, with 2 years to run concurrently with the escape sentence, antedated to 10 December 1999.

For a conviction of murder based on the doctrine of common purpose, the State must prove that the accused subjectively foresaw the possibility that death could result from the planned conduct and reconciled himself to that possibility. Mere participation in a robbery or escape plan that involves disarming a victim does not, without more, warrant the inference that the accused foresaw and accepted the risk of murder being committed. The common purpose to escape and rob does not automatically extend to a common purpose to murder unless the evidence establishes such foresight and acceptance. Where an accused plays a limited role (such as grabbing the victim's legs during an escape) and the plan was to disarm and lock up the victim rather than kill him, a conviction for murder on the basis of common purpose cannot stand if there is no proof of subjective foresight of the possibility of death.

The court observed that it was inherently probable that an escape from custody would be preceded by some discussion and planning, as was demonstrated by the manner in which the plan was executed in this case. The court also noted that the practice at the court was that firearms of court orderlies were never kept cocked and were checked daily to ensure proper working order, which supported the finding that appellant 3 deliberately cocked the weapon before firing. The court expressed sympathy for appellant 2's predicament, noting that he had been advised he had no case to answer on the original charge and that the magistrate's decision to postpone the discharge application for three months, coupled with unaffordable bail, made him vulnerable to the suggestion to escape - factors which, while not excusing his conduct, were relevant to the substantial and compelling circumstances analysis for sentencing purposes.

This case is significant in South African criminal law for its authoritative application of the common purpose doctrine in the context of murder. It clarifies that for a conviction of murder based on common purpose, there must be proof that the accused subjectively foresaw the possibility of death occurring. Mere participation in a robbery or escape plan is insufficient if the murder was not reasonably foreseeable to the particular accused. The case also provides guidance on the application of mandatory minimum sentencing provisions under the Criminal Law Amendment Act 105 of 1997, particularly regarding robbery with aggravating circumstances and what constitutes 'substantial and compelling circumstances' to justify departure from prescribed sentences. The judgment demonstrates how courts should consider factors such as the accused's age, prior record, time in custody, and the circumstances leading to the offence when determining whether to depart from minimum sentences.
