"That the rule rests, at least in part, upon public policy is clear from many authorities, and the convenient starting point of the inquiry is the nature of the underlying policy. It is that parties should be encouraged so far as possible to settle their disputes without resort to litigation and should not be discouraged by the knowledge that anything that is said in the course of such negotiations (and that includes, of course, as much the failure to reply to an offer as an actual reply) may be used to their prejudice in the course of the proceedings. They should, as it was expressed by Clauson J. In Scott Paper Co. v. Drayton Paper Works Ltd. (1927) 44 R.P.C. 151, 156, be encouraged fully and frankly to put their cards on the table. ... The public policy justification, in truth, essentially rests on the desirability of preventing statements or offers made in the course of negotiations for settlement being brought before the court of trial as admissions on the question of liability."
"the Master of the Rolls there affirms the undoubted proposition that production can be ordered of documents even though they may not be admissible in evidence. Nevertheless, if documents come into being under an express, or, I would add, a tacit, agreement that they should not be used to the prejudice of either party, an order for production will not be made. This case seems to me to fall within that principle. This report was clearly made as a result of a 'without prejudice' interview and it was made solely for the purposes of the 'without prejudice' negotiations. The solicitor for the plaintiff himself says in his affidavit that at the time of the interview it was contemplated that steps such as these should be undertaken. I find myself, therefore, in agreement with the decision of Master Burnand and the judge that this is not a case where production should be ordered."
"It seems to me that it would be monstrous to allow the plaintiff to make use - as he certainly would make use - for his own purposes as against the defendants of a document which is entitled to the protection of 'without prejudice' status."
"I am of opinion that in this jurisdiction a party to a correspondence within the 'without prejudice' privilege is, generally speaking, protected from being required to disclose it on discovery or at trial in proceedings by or against the third party."
"Without prejudice communications - any discussions between the parties for the purpose of resolving the dispute between them are not admissible, even if the words 'without prejudice' or their equivalent are not expressly used (Chocoladefabriken Lindt & Sprungli A. G. v. Nestle Co. Ltd. [1978] R.P.C. 287). It follows that documents containing such material are themselves privileged from production."
