Unilever plc v Procter and Gamble Company: CA 4 Nov 1999

The defendant’s negotiators had asserted in an expressly ‘without prejudice’ meeting, that the plaintiff was infringing its patent and they threatened to bring an action for infringement. The plaintiff sought to bring a threat action under section 70 relying on the statements. The judge held the statement inadmissible.
Held: The plaintiff’s appeal failed. Where there had been protracted discussions and negotiations between the parties on a without prejudice basis, it would be quite wrong to take words spoken during such meetings as constituting any threat of infringement proceedings or challenge to a patent so as to found an action for damages. The policy represented by the first statutory threats provision (section 32 of the 1833 Act) was to stop patentees who were (in Pope’s words about Addison) ‘willing to wound but afraid to strike’ from holding the sword of Damocles above another’s head. The modern cases show that the protection of admissions against interest is the most important practical effect of the rule, but to dissect out identifiable admissions and withhold protection from the rest of without prejudice communications (except for a special reason) would not only create huge practical difficulties but would be contrary to the underlying objective of giving protection to the parties to speak freely and to compromise, admitting certain facts. Parties cannot speak freely at a without prejudice meeting if they must constantly monitor every sentence, with lawyers or patent agents sitting at their shoulders as minders.
Robert Walker LJ said that admissions against interest should be protected under the without prejudice rule, ‘In those circumstances I consider that this court should, in determining this appeal, give effect to the principles stated in the modern cases, especially Cutts v Head, Rush and Tompkins and Muller. Whatever difficulties there are in a complete reconciliation of these cases, they make clear that the without prejudice rule is founded partly in public policy and partly in the agreement of the parties. They show that the protection of admissions against interest is the most important practical effect of the rule. But to dissect out identifiable admissions and withhold protection from the rest of without prejudice communications (except for a special reason) would not only create huge practical difficulties but would be contrary to the underlying objective of giving protection to the parties in the words of Lord Griffiths in Rush and Tompkins at page 1300:
‘To speak freely about all issues in the litigation both factual and legal when seeking compromise and, for the purposes of establishing a basis of compromise, admitting certain facts.’
The parties cannot speak freely at a without prejudice meeting if they must constantly monitor every sentence, with lawyers or patent agents sitting at their shoulders as minders.’ and ‘Apart from any concluded contract or estoppel, one party may be allowed to give evidence of what the other said or wrote in without prejudice negotiations if the exclusion of the evidence would act as a cloak for perjury, blackmail or other ‘unambiguous impropriety’ (the expression used by Hoffman LJ in Forster v Friedland) . . but this court has, in Forster v Friedland and Fazil Alizadeh v Nikbin . . warned that the exception should be applied only in the clearest cases of abuse of a privileged occasion.’
