This is often a function of what is known by the lawyer at the time of the examination. So, for example, a defence lawyer examining an eye-witness in a case who was told by the accused that he did the offence cannot suggest to the witness that they are mistaken as to whom they identified. Similarly, in a case where the defence is alibi, the defence counsel cannot still attack the credibility of the witnesses establishing the offence as he does not have a basis to believe they are being untruthful. | This is often a function of what is known by the lawyer at the time of the examination.
