However, the determination sought to be reviewed in this case is in a different category. Section 131A of the Evidence Act provides for the determination of an objection in respect of a requirement for disclosure, which would extend to the summons issued in this case. It is clearly contemplated that that determination will be made, in an appropriate case, prior to the commencement of the proceedings and will apply the relevant provisions with respect to privilege contained in the Evidence Act. The determination of the provision of such information, prior to the commencement of the actual hearing, has the capacity to affect and inform the course, conduct and nature of the hearing. In the case of the defence, it could conceivably have real implications with respect to the conduct of its case, including the decision by the defendant as to whether to give or adduce evidence. It is certainly possible to test at the conclusion of the hearing whether there has been a miscarriage of justice, but there are discernible benefits with respect to the due and efficient administration of justice, if such a decision is made, and if necessary reviewed, prior to the commencement of the hearing proper. I am satisfied, therefore, that the determination of the magistrate was an order within the meaning of s 107, and, accordingly, the Court has jurisdiction to conduct a review of that determination."
