This dissertation investigates the manner in which facts are proven with specific emphasis on the role which the concept of ‘probabilities’ plays in achieving the ‘burden of proof. It is illustrated that the concept of ‘probabilities’ plays a central role throughout the process of determining the accountability of a litigant, including fact-finding during the evaluation of the adduced evidence and the application of the burden of proof. This study distinguishes between the findings of individual facts, as opposed to the finding of whether the case of a party, as reflected by the cumulative effect of the individually proven facts, has been proven. It is submitted that, despite traditionally perceived views, the concept of ‘probabilities’ is applied in exactly the same manner to both these aspects of a legal dispute, the only variable being the degree of probabilities as determined by a specific stage and nature of the litigation. The research focuses on both criminal and civil cases. The dissertation is based on current South African practices as reflected in judgments in different law reports and, to some extent, on English and American legal practices.
