To qualify as an expert under the Act the witness must be specially skilled in the field in which he is giving evidence and whether or not a witness can be regarded as an expert is a question for the Judge to decide; the decision must be based on legal evidence before him. As Sir Verity, CJ (Nigeria) put it in Ajani v. The Controller of Customs 14 WACA 34 at 36: “It is clear, I think, that the test must always be the knowledge and experience of the particular witness and whether the evidence justifies the conclusion that he is ‘specially skilled’ within the meaning of the Evidence Ordinance, which means no more than that he has special knowledge, training or experience in the matter in question.”
