“(1) A party to whom a document has been disclosed may use the document only for the purpose of the proceedings in which it is disclosed, except where- (a) the document has been read to or by the court, or referred to, at a hearing which has been held in public; (b) the court gives permission; or (c) the party who disclosed the document and the person to whom the document belongs agree.” (a) the document has been read to or by the court, or referred to, at a hearing which has been held in public; (b) the court gives permission; or (c) the party who disclosed the document and the person to whom the document belongs agree.”
“First, a party receiving documents on discovery impliedly undertakes not to use them for a collateral purpose. Secondly, the obligation to give discovery is an invasion of the litigant’s right to privacy and confidentiality. This is justified only because there is a public interest in ensuring that all relevant evidence is provided to the court in the current litigation. Therefore the use of those documents should be confined to litigation. Thirdly the rule against using disclosed documents for a collateral purpose will promote compliance with the disclosure obligation.”
“(i) The collateral purpose rule now contained inCPR 31.22 exists for sound and long established policy reasons. The court will only grant permission under 31.22(1)(b) if there are special circumstances which constitute a cogent reason for permitting collateral use. … (iii) There is a strong public interest in facilitating the just resolution of civil litigation. Whether that public interest warrants releasing a party from the collateral purpose rule depends upon the particular circumstances of the case. Those circumstances require careful examination. There are decisions going both ways in the authorities cited above.”
“… there is the most unusual feature of this case that the very same issue, namely whether the 1981 agreement infringes Article [101], is being considered concurrently by two tribunals, namely this court and the Commission. Clearly both tribunals have to apply the same criteria. In so far as facts have to be decided in order to reach a conclusion on the issue, both tribunals need to decide the same facts. For the purpose of any such decision the same evidential material ought, one would have thought, to be available to both tribunals. As the tribunals are completely independent of each other, there cannot be certainty that they will necessarily reach the same conclusion of fact on the same evidence or give the same weight to every individual piece of evidence. But it appears to me to be highly desirable, to put it no higher, that each tribunal should have the opportunity of evaluating the same evidence unless it can be seen that the particular material which is relied upon is devoid of relevant evidential value so far as the issue is concerned.”
“Clearly the defendants cannot validly complain about use of the documents in the way proposed on the ground that the relevant documents may assist the plaintiffs to succeed in their contentions. The defendants, of course, do not put their [objection] The reported text reads “obligation” but that seems to be a typographical error. in this way.”
“(c) to better enable the regulatory body and the court to reach the same conclusions, it is important that the evidential material which is before the court is available before the regulatory body. Accordingly (and most particularly in a case where the procedural rules of the regulatory body and the court regarding disclosure are different) the court will release crossundertakings given by parties on disclosure to enable this object to be achieved: see Apple Corps v Apple Computers.”
“In order to ensure compliance with the principles of legal certainty and the uniform application of the Community competition rules in a system of parallel powers, conflicting decisions must be avoided.”
