We have considered the submissions of counsel. We accept the suggestion in principle. However, there must be evidence of: (1) the witness's knowledge of the person and (2) his concerns for security, et cetera, to determine if a pseudonym can be allowed by the Court. Therefore, we will hear this is private session to determine if it is appropriate that a number rather than a reference to the person by name is adduced in the course of evidence. So if the witness can be brought in, I will remind him of his oath and we will go into private session and deal with that matter first, Mr Bangura, Mr Griffiths. Counsel, I should remark that this was a procedure that we have adopted in the past.
