[12] As to that explanation, the plaintiff's solicitors had been told, but had apparently misunderstood, that the defendant had leave to issue a third party notice against its insurer; the defendant filed that third party notice on 12 November 2001. The solicitor's affidavit said nothing at all about when the mistake was realised, or how it had happened or what step was now proposed. However, Mr P Alcorn of counsel, who appeared for the plaintiff before the learned District Court judge, did not read any affidavit material from the appellant at all, either as to the circumstances of the accident or the reason for the delay. Mr S Lynch, appearing for the appellant in this Court, likewise did not seek leave to read any affidavit material from Mr Hall as to the delay, and specifically did not invite the court to infer that the delay was due to any fault on the part of Mr Hall's solicitor. That meant, as Mr Lynch readily conceded, that before both the learned trial judge and this Court, the delay was simply not explained in any submission or argument advanced on Mr Hall's behalf, or by any evidence from Mr Hall. Although this Court was not asked so to conclude, the limited material suggested that any fault lay with the solicitor and not the client. The problem for Mr Hall was that there simply was no evidence from him.
