108CException—evidence of persons with specialised knowledge

108C Exception—evidence of persons with specialised knowledge (1) The credibility rule does not apply to evidence given by a person concerning the credibility of another witness if— (a) the person has specialised knowledge based on the person's training, study or experience; and (b) the evidence is evidence of an opinion of the person that— (i) is wholly or substantially based on that knowledge; and (ii) could substantially affect the assessment of the credibility of the witness; and (c) the court gives leave to adduce the evidence. (2) To avoid doubt, and without limiting subsection (1)— (a) a reference in that subsection to specialised knowledge includes a reference to specialised knowledge of child development and child behaviour (including specialised knowledge of the impact of sexual abuse on children and their behaviour during and following the abuse); and (b) a reference in that subsection to an opinion of a person includes, if the person has specialised knowledge of that kind, a reference to an opinion relating to either or both of the following— (i) the development and behaviour of children generally; (ii) the development and behaviour of children who have been victims of sexual offences, or offences similar to sexual offences.
