"Normally this court will not entertain an application for a quashing order in relation to a decision made in a magistrates' court where the proceedings in that court are not complete. In R v Rochford Justices ex-parte Buck(1978) 68 Cr App R 114 it was said that there is no jurisdiction to do so, and a distinction was drawn between an order to direct a magistrate to hear and determine a matter, which can be obtained if he refuses to do so, and an order, as Cockburn CJ put it in Carden(1879) 5 QBD 1 at 5, "to control the magistrate in the conduct of the case or to prescribe to him the evidence which he shall receive or reject."
"The obligation of this Court to keep out of the way until the magistrate has finished his determination seems to me to be a principle properly to be applied both to summary trial and to committal proceedings. Accordingly, I would be prepared to dispose of this matter on the first argued point, namely, that there was no jurisdiction in this Court to interfere with the justices' decision, that not having been reached by termination of the proceedings below."
"(1) Where a justice of the peace is satisfied that- (a) any person in England or Wales is likely to be able to give material evidence, or produce any document or thing likely to be material evidence, at the summary trial of an information or hearing of a complaint… by a magistrates' court, and (b) it is in the interests of justice to issue a summons under this subsection to secure the attendance of that person to give evidence or produce the document or thing, the justice shall issue a summons directed to that person requiring him to attend before the court at the time and place appointed in the summons to give evidence or to produce the document or thing."
"The central principles to be derived from those authorities are as follows: (i) to be material evidence documents must be not only relevant to the issues arising in the criminal proceedings, but also documents admissible as such in evidence; (ii) documents which are desired merely for the purpose of possible cross-examination are not admissible in evidence and, thus, are not material for the purposes of section 97; (iii) whoever seeks production of documents must satisfy the Justices with some material that the documents are 'likely to be material' in the sense indicated, likelihood for this purpose involving a real possibility, although not necessarily a probability; (iv) it is not sufficient that the applicant merely wants to find out whether or not the third party has such material documents. This procedure must not be used as a disguised attempt to obtain discovery."
"Mr Lucas explained to the Deputy District Judge that the documents, reports and service sheets were necessary to his defence and were needed by his experts to enable them to prepare their reports. The Deputy District Judge asked the Crown if they had any objections to this application. There was no opposition to the application she was considering and it was never suggested by the Crown that the items, documents, exhibits, service sheets etc were not necessary and essential to the defence in the criminal case. Accordingly the Witness Summons ...was issued."
