Credibility evidence, in relation to a witness or other person, is evidence relevant to the credibility of the witness or person that--
(a) is relevant only because it affects the assessment of the credibility of the witness or person, or
(b) is relevant--(i) because it affects the assessment of the credibility of the witness or person, and(ii) for some other purpose for which it is not admissible, or cannot be used, because of a provision of Parts 3.2 to 3.6.
Notes--:1 Sections 60 and 77 will not affect the application of paragraph (b), because they cannot apply to evidence that is yet to be admitted.2 Section 101A was inserted as a response to the decision of the High Court of Australia in Adam v The Queen(2001) 207 CLR 96 .
