If, in the course of the hearing before the Court of Appeal, it had been sought to expand the particulars of the allegations against the appellant to include an allegation that he had deliberately given false evidence to that Court, a question would have arisen whether it would be reasonable to require the appellant to deal at the one time with the original particularized complaints against him and a complaint that the evidence which he gave in answer to those complaints was deliberately false. Obviously, there would have been something to be said for the view that it would have been unfair to require the appellant to establish that he had been honestly mistaken in giving the evidence upon which he relied before that evidence had been rejected by the Court of Appeal. In fact, there was no attempt to amend the particulars of complaint. In the absence of any such amendment, the issue before the Court of Appeal remained whether the effect of all the evidence, including the appellant's evidence about the car park conversation, was that the particularized complaints had been made out to the requisite standard of proof [19] . The appellant could not realistically be expected, while maintaining the reliability of his evidence in relation to that issue, to have set out to establish how and why that evidence was honestly mistaken. If the Court of Appeal, after reaching the conclusion that the appellant's evidence about the car park conversation should be rejected, had thought it desirable or necessary to consider whether the appellant had been guilty of professional misconduct in that he had deliberately given false evidence before it, "at the very least a new charge would have [had] to be laid (before it could be relied upon) so that [the appellant could] then know of it, appreciate what he [had] to meet and be allowed ample opportunity to meet it" [20] . Such a new charge could have been laid by appropriate amendment to the particulars of complaint and an appropriate opportunity of being heard could have been provided by relisting the matter for that purpose. In fact, however, no specific charge of deliberately giving false evidence before the Court of Appeal was ever laid against the appellant and no opportunity was extended to him to deal with such a specific charge before the Court of Appeal made its initial finding of guilt.
