“66. The relevant legal principles are conveniently summarised by Blair J. in paragraph 17 of Assetco.CPR 31.16 provides that the court may make an order for pre-action disclosure only if certain conditions are satisfied: i). The respondent and applicant must both be likely to be parties to subsequent proceedings. It is not however necessary to show in addition that the initiation of such proceedings is itself likely: Black v Sumitomo Corp[2002] 1 WLR 1562 at [71 – 72], Rix LJ, which is the leading case on the rule. ii). The documents sought must fall within the scope of the standard disclosure which the respondent would have to give in the anticipated proceedings. It follows that at the time of the application, the issues must be sufficiently clear to enable this requirement to be properly addressed. iii). Disclosure before proceedings have started must be desirable (i) to dispose fairly of the anticipated proceedings, (ii) to assist the dispute to be resolved without proceedings, or (iii) to save costs:CPR 31.16 (3) (d). iv). In considering whether to make an order, among the important considerations are the nature of the loss complained of, the clarity and identification of the issues raised by the complaint, the nature of the documents requested, the relevance of any protocol or pre-action inquiries, and the opportunity which the complainant has to make his case without pre-action disclosure (Black v Sumitomo Corp at [88]). v). The anticipated claim must have a real prospect of success. vi). In the commercial context, a pre-action disclosure order, even if not exceptional, is unusual.”
“CPR 31.16 (3)(a) and (b): “likely to be a party”. 70.. The application has to be made by “a person … likely to be a party to subsequent proceedings” against “a person … likely to be a party to the proceedings” (section 33(2)) and those requirements are reflected (in reverse order) inCPR 31.16 (3)(a) and (b). There is no longer any statutory requirement that “a claim … is likely to be made”…CPR 31.16 (3)(d): “desirable” 79.. This is a difficult test to interpret, for it is framed both in terms of a jurisdictional threshold (“only where”) and in terms of the exercise of a discretionary judgment (“desirable”)… 81.. It is plain not only that the test of “desirable” is one that easily merges into an exercise of discretion, but that the test of “dispose fairly” does so too. In the circumstances, it seems to me that it is necessary not to confuse the jurisdictional and the discretionary aspects of the sub-rule as a whole. In Bermuda v. KPMG Waller LJ contemplated (at para 26) that sub-rule (d) may involve a two-stage process. I think that is correct. In my judgment, for jurisdictional purposes the court is only permitted to consider the granting of pre-action disclosure where there is a real prospect in principle of such an order being fair to the parties if litigation is commenced, or of assisting the parties to avoid litigation, or of saving costs in any event. If there is such a real prospect, then the court should go on to consider the question of discretion, which has to be considered on all the facts and not merely in principle but in detail. 82.. Of course, since the questions of principle and of detail can merge into one another, it is not easy to keep the two stages of the process separate. Nor is it perhaps vital to do so, provided however that the court is aware of the need for both stages to be carried out. The danger, however, is that a court may be misled by the ease with which the jurisdictional threshold can be passed into thinking that it has thereby decided the question of discretion, when in truth it has not. This is a real danger because first, in very many if not most cases it will be possible to make a case for achieving one or other of the three purposes, and secondly, each of the three possibilities is in itself inherently desirable. 83.. The point can be illustrated in a number of ways. For instance, suppose the jurisdictional test is met by the prospect that costs will be saved. That may well happen whenever there are reasonable hopes either that litigation can be avoided or that pre-action disclosure will assist in avoiding the need for pleadings to be amended after disclosure in the ordinary way. That alternative will occur in a very large number of cases. However, the crossing of the jurisdictional threshold on that basis tells you practically nothing about the broader and more particular discretionary aspects of the individual case or the ultimate exercise of discretion. For that, you need to know much more: if the case is a personal injury claim and the request is for medical records, it is easy to conclude that pre-action disclosure ought to be made; but if the action is a speculative commercial action and the disclosure sought is broad, a fortiori if it is ill-defined, it might be much harder… Discretion …. 88.. That discretion is not confined and will depend on all the facts of the case. Among the important considerations, however, as it seems to me, are the nature of the injury or loss complained of; the clarity and identification of the issues raised by the complaint; the nature of the documents requested; the relevance of any protocol or pre-action inquiries; and the opportunity which the complainant has to make his case without pre-action disclosure… …95.. In my judgment, the more focused the complaint and the more limited the disclosure sought in that connection, the easier it is for the court to exercise its discretion in favour of pre-action disclosure, even where the complaint might seem somewhat speculative or the request might be argued to constitute a mere fishing exercise. In appropriate circumstances, where the jurisdictional thresholds have been crossed, the court might be entitled to take the view that transparency was what the interests of justice and proportionality most required… The more diffuse the allegations, however, and the wider the disclosure sought, the more sceptical the court is entitled to be about the merit of the exercise. …97.. In the present circumstances, the expressed determination of Mr Black to commence proceedings, and the avenues open to him to obtain documentation or (as it seems) information from other sources, militate against him. 98.. In this connection, as this case demonstrates, there is considerable danger of a request for pre-action disclosure leading to what must be expensive satellite litigation in connection with proceedings which have not yet been initiated.”
