" ..... I believe I state the rule of the Court correctly when I say that, where a given matter becomes the subject of litigation in, and of adjudication by, a Court of competent jurisdiction, the Court requires the parties to that litigation to bring forward their whole case, and will not (except under special circumstances) permit the same parties to open the same subject of litigation in respect of matter which might have been brought forward as part of the subject in contest, but which was not brought forward, only because they have, from negligence, inadvertence, or even accident omitted part of their case. The plea of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at that time."
"The rule is thus in two parts. The first relates to those points which were actually decided by the court: this is res judicata in the strict sense. Secondly, those which might have been brought forward at the time, but were not. The second is not a true case of res judicata but rather is founded on the principle of public policy in preventing multiplicity of actions, it being in the public interest that there should be an end to litigation: the court will stay or strike out the subsequent action as an abuse of process."
" ..... it ought only to be applied when the facts are such as to amount to an abuse: otherwise there is a danger of a party being shut out from bringing forward a genuine subject of litigation."
"Within one issue, there may be several points available which go to aid one party or the other in his efforts to secure a determination of the issue in his favour. The rule then is that each party must use reasonable diligence to bring forward every point which he thinks would help him. If he omits to raise any particular point, from negligence, inadvertence, or even accident (which would or might have decided the issue in his favour) he may find himself shut out from raising that point again, at any rate in any case where the self-same issue arises in the same or subsequent proceedings. But this again is not an inflexible rule. It can be departed from in special circumstances."
"We write to confirm that we have reached agreement for the resolution of our clients' Notice of Motion dated30th June 1993 as follows:
"As the person of this firm dealing with the copyright aspects of the claim my intention, when writing my firm's letters of 5 and 8 July, was, unless we obtained the contractual undertakings demanded, to commence separate proceedings with Mr Graebe as Plaintiff. I had Mr Graebe's authority to proceed, and intended to apply for an interim injunction to restrain the Defendant from infringing copyright. Those were my clear instructions. I also intended to apply for the passing off and copyright actions to be consolidated.
"Mr Platts-Mills, Counsel for the Defendant, explained that the parties had agreed that the action be dealt with by way of speedy trial. He handed up to the Judge the Minutes of Order.
"Guy Tritton addressing the Judge and confirming that the copyright case for the plaintiffs was stronger than the passing off case and the interlocutory would canvass passing off and copyright issues and may be far more complex than the trial itself [because] the trial would only have half the complexity of the interlocutory and there is an undertaking as to damages in the meantime and the terms are agreed, the sensible course was to crack on with the speedy
"By reason of the matters aforesaid, the Defendants lost profit on sales of the product which it would have made between7th July 1993 and 20th [July] 1994, amounting to£377,803 ."
"Paragraph 5 ..... is denied. The Plaintiffs aver that the marketing of the FLOT'AIR cushions would have been unlawful absent the injunction and/or undertakings as such marketing would have constituted an infringement of the Second Plaintiff's copyright and/or the copyright of Mr ..... Graebe, at all material times the president and principal shareholder of the Second Plaintiff, who designed the ROHO cushion. The following paragraphs ..... concern the ..... copyright claim ..... "
"Whether the Plaintiffs are entitled to rely upon copyright which is alleged to subsist in the design of their air flotation cushions in order to contend that the Plaintiffs can be under no liability whatsoever in respect of the Defendant's claims in the inquiry, on the basis that the Defendant could not lawfully have sold the FLO'TAIR cushion without infringing copyright."
" ..... I must start with the proposition that, at least on the face of it, permitting the plaintiffs to raise the copyright issue at this stage would breach the rule in Henderson . However, it is clear that the rule is subject to exceptions."
"All estoppels are not odious but must be applied so as to work justice and not injustice and I think the principle of issue estoppel must be applied to the circumstances of the subsequent case with this overriding consideration in mind."
" ..... to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at the time."
"Where I part company with Mr Simon [counsel for the defendants in the case] is not so much with this part of his argument as with his basic premise that the rule is applicable to the present case. In my judgment the circumstances are such that it could not fairly be said, to use the words of Lord Kilbrandon in Yat Tung Investment Co Ltd v Dao Heng Bank Ltd[1975] AC 581 , 590 that the matters now raised could and therefore should have been litigated in the earlier proceedings."
" ..... in the circumstances of the present case the matter now raised could not and should not have been litigated first time round."
" ..... in relation to copyright, we were planning on taking a licence of right for the drawings on1st August 1994 . That instead of a hearing of a very substantial motion including copyright the sensible course was to have a speedy trial as to passing off and so the matter would be resolved by the time we had got the licence of right proceedings ..... In the meantime, the Defendant was prepared to give undertakings until Judgment for further Order as set out. Counsel explained the copyright position to the judge, in particular, the licence of right being available as at1st August 1994 and so that issue falls away."
