 The decision whether to allow a party to adduce a particular item of evidence is one that the judge has to make and arises in the course of a trial.  Section 2  above dealt with the conditions that must be satisfied for a witness’s testimony, a document or an object to be received as evidence. At the end of the trial, the fact-finder must consider all the evidence that has been presented and reach a verdict. Although verdict deliberation is sometimes subjected to various forms of control through legal devices such as presumptions and corroboration rules, such control is limited and the fact-finder is expected to exercise personal judgment in the evaluation of evidence (Damaška 2019). Having heard or seen the evidence, the fact-finder now has to evaluate or ‘weigh’ it in reaching the verdict. Weight can refer to any of the following three properties of evidence: (a) the probative value of individual items of evidence, (b) the sufficiency of the whole body of evidence adduced at the trial in meeting the standard of proof, or (c) the relative completeness of this body of evidence. The first two aspects of weight are familiar to legal practitioners but the third has been confined to academic discussions. These three ideas are discussed in the same order below.
