s 30 Expert reports.
(1) An expert report shall be admissible as evidence in criminal proceedings, whether or not the person making it attends to give oral evidence in those proceedings. (2) If it is proposed that the person making the report shall not give oral evidence, the report shall only be admissible with the leave of the court. (3) For the purpose of determining whether to give leave the court shall have regard— (a) to the contents of the report; (b) to the reasons why it is proposed that the person making the report shall not give oral evidence; (c) to any risk, having regard in particular to whether it is likely to be possible to controvert statements in the report if the person making it does not attend to give oral evidence in the proceedings, that its admission or exclusion will result in unfairness to the accused or, if there is more than one, to any of them; and (d) to any other circumstances that appear to the court to be relevant. (4) An expert report, when admitted, shall be evidence of any fact or opinion of which the person making it could have given oral evidence.
