[24] The plaintiffs' position in relation to continuing the proceeding against the fourth defendant is clear. That is because the material which has been filed on behalf of the fourth defendant for the purpose of the hearing of the relevant applications shows that it is likely that the letter dated 3 September 1991 which is the subject of the claims against the fourth defendant was not, in fact, sent. That is the conclusion that can be drawn from the affidavits of Mr AB Turner, Mr PL Twyford-Jones, Mr J Scrivens and Ms TL Jackson (which relates to the existence of this letter) all filed on 30 November 2001 and the affidavit of the fourth defendant filed by leave on 3 December 2001. The alleged recipient of the letter died on 13 February 1999. In addition, the fourth defendant's affidavit shows that, unsurprisingly, his memory of the relevant events after the passage of time is not good.
