“31. It seems to me that there is a potential problem lurking here, but it is largely dealt with by the fact that on the evidence that I have seen, and that has been provided, and indeed on the defendant’s own assertions, it does not seem that the defendant is going to be able to raise a case that in any particular instance and associate was indeed a confidential source… In those circumstances it seems to me that the confidential source point is a matter of pure speculation and the defendant is not going to be able to make a positive case that anyone was a confidential source. At this stage, therefore, it seems to me that that particular point has no particular weight. 32. Mr Emmerson’s other point was that his client felt it could not freely produce the incoming call data and, therefore, to give the claimants that outgoing call data would be to give them an incomplete and misleading picture. If there was incoming data, even if not from a source, it would provide an entirely different evidential framework against which to judge the significance of outgoing calls. He may be right about the evidential framework but that is going to have to be a matter for his clients to address when they approach the litigation. It seems to me that on any footing data about calls to associates is going to be a disclose will disclosable or discoverable matter. That is the basis on which I made my original order. 33. If the defendant wishes to counter-balance that with its own information then it will have to approach the obtaining of that information in an appropriate way. If it does not produce that information then the court will be left to draw such inference as it is proper to draw from one side of the information only, because there will be only the one side of the information before the court. This may put the defendant in some difficulty in working out how to approach the matter, but it seems to me that it would be a completely wrong basis to refuse to allow the disclosure of outgoing calls on the footing that in some cases, which one cannot identify in case the person is a source, there will be some incoming data which should not be disclosed because of the possibility of a source. That would require every piece of outgoing data to be infected by the possibility (and it is no more than that on the evidence) that somewhere in somebody else’s call data in an entirely different case, there is a source. That, it seems to me, is no basis on which to deal with disclosure.”
