“(3) The court may make an order under this rule only where— (a) the respondent is likely to be a party to subsequent proceedings; (b) the applicant is also likely to be a party to those proceedings; (c) if proceedings had started, the respondent’s duty by way of standard disclosure, set out in rule 31.6, would extend to the documents or classes of documents of which the applicant seeks disclosure; and (d) disclosure before proceedings have started is desirable in order to (i) dispose fairly of the anticipated proceedings; (ii) assist the dispute to be resolved without proceedings; or (iii) save costs.” (a) the respondent is likely to be a party to subsequent proceedings; (b) the applicant is also likely to be a party to those proceedings; (c) if proceedings had started, the respondent’s duty by way of standard disclosure, set out in rule 31.6, would extend to the documents or classes of documents of which the applicant seeks disclosure; and (d) disclosure before proceedings have started is desirable in order to (i) dispose fairly of the anticipated proceedings; (ii) assist the dispute to be resolved without proceedings; or (iii) save costs.”
“23. I accept Mr Huckle’s submission that there is no jurisdictional “arguability threshold”, and I think I can fairly say that Mr Kinnier was not by the end of his oral submissions seeking to persuade us that there was. The jurisdictional requirements for the making of an order underCPR 31.16 are expressly set out at heads (a)-(d) in para. (3) of the rule, and they say nothing about the applicant having to establish some minimum level of arguability. If such a requirement exists it can only be implicit, and I see no basis for making any such implication. If heads (a)-(b) required an applicant to show that it was likely that proceedings would be commenced I could see an argument that that necessarily involved showing that the putative proceedings had some chance of success (because people are not likely to start hopeless cases). But it is clear from Black v Sumitomo that there is no such requirement: all that has to be shown is that it is likely that the respondent would be a party to such proceedings if commenced (see para. 71 of Rix LJ’s judgment – para. 10 (4) above). I accept of course that it cannot have been the intention of the rule-maker that a party should be entitled to pre-action disclosure in circumstances where there was no prospect of his being able to establish a viable claim; but in such a case disclosure could and no doubt would be refused in the exercise of the discretion which arises at the second stage of the enquiry.”
