This chapter discusses the law relating to the evidence of opinion. It first considers the rule on the evidence of opinion and explains its rationale, especially the nature of its relationship to the rules excluding hearsay. The chapter discusses two broad spheres of evidence of opinion: expert and non-expert. The first concerns matters calling for specialized skill or knowledge. In this sphere, the only questions are whether the subject of inquiry does raise issues calling for expertise, and whether the witness is a qualified expert. In the residuary non-expert sphere, evidence of opinion will be excluded if the subject is one with regard to which fact and inference can conveniently be kept separate. The chapter then illustrates the operation of the rule, together with the two areas of expert and non-expert opinion in which there are exceptions. Finally, this chapter deals with the reform of the rule.
