The ratio decidendi is that: (1) In determining whether grievous bodily harm has been inflicted for purposes of establishing aggravating circumstances in robbery under section 1(b)(ii) of the Criminal Procedure Act 51 of 1977, the court is entitled to have regard to the whole complex of objective factors involved in the assault upon the victim, including the results which flowed from the infliction of the wounds. The consequences suffered by the victim, including death resulting from the infliction of bodily harm, are relevant considerations. (2) Where parties to a common purpose to rob are established and the infliction of grievous bodily harm upon the victim is proved, all parties are guilty of robbery with aggravating circumstances, regardless of which party actually inflicted the harm, and it is not necessary to prove that this consequence was foreseen by the parties. (3) Corroboration of evidence by an accomplice implicating a co-accused is not an absolute requirement where the accomplice is found to be a satisfactory and convincing witness while the accused is the opposite. What is required is proof beyond reasonable doubt based on an appraisal of all the evidence.
