(a)furnish the other party or parties with a statement in writing of any finding or opinion which he proposes to adduce by way of such evidence; and

(b)Where a request in writing is made to him in that behalf by any other party, provide that party also with a copy of (or if it appears to the party proposing to adduce the evidence to be more practicable, a reasonable opportunity to examine) the record of any observation, test, calculation or other procedure on which such finding or opinion is based and any document or other thing or substance in respect of which any such procedure had been carried out.

Explanatory Note

(This note is not part of the Rules.)

These Rules provide for mutual disclosure of expert evidence between the parties to criminal proceedings in the Crown Court. Rule 3 requires a party to disclose any expert evidence which he proposes to adduce as soon as practicable after committal or the ordering of a retrial. Rule 3(1)(b) enables a party to examine the basis of any findings or opinions proposed to be adduced by way of expert evidence by another party. Rule 4 provides for a party to withhold any matter where he has reasonable grounds for suspecting that its disclosure might lead to intimidation or the course of justice being interfered with. In such a case the party is required to give to the other party notice in writing, which must include the grounds on which disclosure is being withheld. By Rule 5 a party who fails to comply with rule 3 in respect of any evidence may not adduce that evidence without the leave of the court.

The Rules, by virtue of rule 1, come into force on 15th July 1987 and, by virtue of rule 2, have effect in relation to proceedings in which a person is committed for trial or ordered to be retried on or after that date.
