4 I agree with the judgment of my brother Osborn that the application and the appeal against conviction should be allowed and for the reasons which he has stated. I wish only to add the following.
5 The authorities make it clear that a Longman warning should not be understood as the product of any undue tenderness for accused persons or from any suspicion that complainants or, indeed, any class of witnesses are or may be inherently unreliable. It is part of a concession accorded to the prosecution and that very old cases might be permitted to go to trial[1] rather than be stayed for fear that the lapse of time might cause injustice to the accused.[2] It is a warning which is quite separate from the comment or warning which may be directed to the impact of the
passage of time upon the recollection of the complainant and other prosecution witnesses or the inference which the jury might draw from the delay of the complainant in bringing the allegation forward.[3]
6 In summary, the warning must satisfy certain requirements:
(1) It must be, not a mere comment, but a warning couched in firm and unmistakable terms;[4]
(2) It must be made clear to the jury that it is a warning which carries the authority of the judge;
(3) It must be made clear to the jury that the need for the warning arises from the long experience of the law in cases of this kind;
(4) It must identify the particular matters in the case which, by reason of the delay, have left the accused at a disadvantage at the trial and therefore risk causing an injustice;[5]
(5) It must make plain to the jury that, by reason of this disadvantage, it would be dangerous or unsafe to convict the accused on the complainant's evidence alone, unless, having scrutinised the evidence with great care, considering the matters relevant to its evaluation, and paying heed to the warning, the jury is convinced of the truth and accuracy of that evidence.[6]
7 It is clear from cases such as EO [7] that this warning must be tailored to meet the requirements of the case and that its terms and manner of presentation may vary depending upon the circumstances. Nevertheless, having searched the charge in this case to see whether the essential features of this warning are to be found, I regret that, essentially for the reasons set out by my brother Osborn, I, too, have been
unable to conclude that the terms and manner in which the trial judge presented the warning to the jury meet these requirements.
8 Accordingly, I would allow the application and the appeal against the conviction.
