Anthony B, Big A and Messey. In view of the totally incorrect and unfounded allegations in these posts, the thread is currently under consideration by solicitors, details of whom can be provided if required. As the matter is therefore now sub judice, I cannot respond other than to enlighten Messey in particular of the role, and duties, of an expert witness, as clearly he is ignorant of such matters.
1. It is common practice, in cases such as these, for the Defendants (and, as in this case, the prosecution) to appoint expert witnesses.
2. An expert witness is not permitted to act as an advocate for either party, and their evidence would be dismissed (case law suggests dismissed in total) should he/she try to do so.
3. The sole duty of an expert witness is to advise the Court. No duty is owed to the instructing party(ies).
4. An expert witness report must be totally impartial, while advising the Court on the evidence presented to it.
5. By law, an expert witness report must contain a statement that the expert understands that his duty is to serve the Court, and that he has complied with that duty.
6. An expert witness report must, by law, contain a statement of truth that opens the expert to proceedings for perjury should any fact or statement be shown to be untrue.
7. Courts prefer the experts from each side to prepare a joint and, as far as possible, fully agreed report. This originally emanated from reforms of the justice system in civil law, as part of the Woolf reforms that were intended to take away the adversarial approach to justice.
While, as noted above, I am restrained from making any more specific comment on this case, with regard to Big A's allegation that the Defendants in this case did not plead guilty, it is within the public arena that the Defendants did plead guilty to the offences for which they were fined.
