‘The ‘without prejudice rule’ is a rule governing the admissibility of evidence and is founded on the public policy of encouraging litigants to settle their differences rather than litigate them to a finish. It is nowhere more clearly expressed than in the judgment of Oliver LJ in Cutts v Head[1984] 1 All ER 597 at 605-6,[1984] Ch 290 at 306: ‘That the rule rests, at least in part, on 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 RPC 151 at 156, be encouraged freely 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 rule applies to exclude all negotiations genuinely aimed at settlement whether oral or in writing from being given in evidence.’
