"[3] It seems to me to be a reasonable inference from what their Honours have said that all the current Justices of the High Court, excepting the Chief Justice and McHugh J, take the basic position that in any criminal trial a feature of which is substantial delay in complaint of alleged sexual offences then charged against the particular accused, a Longman direction must be given. Not only must the direction be given; but it must be cast in a form that manifests, and is seen plainly to manifest, certain characteristics which one can draw, as follows, from the various statements of principle in Longman itself and in the subsequent decisions in Crampton and in Doggett;
...
(f) The initial trigger for any Longman direction is the passage of time between the alleged offence and first complaint. No doubt, and as Kirby J observes in Doggett (at 1309 [127]; 28 [127]), '[t]he criterion for the provision of a warning as stated in Longman is not mathematically precise'. His Honour goes on to say that 'in a case involving a comparatively short interval between the alleged offence and a subsequent complaint to family members or to authorities, a warning might not be necessary' (emphasis added). His Honour refers in a footnote to Crofts, where the delay between the first alleged offence and complaint was about six years, although there had been offences allegedly continuing until about six months before complaint; and Jones v The Queen (1997) 191 CLR 439, where there was a delay in the order of four years between offence and complaint.
On these particular points, Gaudron J, Gummow J, Hayne J and Callinan J in the judgments variously delivered by their Honours in Crampton and in Doggett, are not, I think, as precise as is Kirby J. I think, nevertheless, that the prudent inference to be drawn from what their Honours have variously said in Crampton and in Doggett is that they would support, at least generally, the propositions advanced by Kirby J.
It is, I think, clear enough that a delay in the order of 20 years would require, imperatively in the view of the current majority opinion in the High Court, a Longman direction, and a strong one at that. What is not clear is whether there is any, and if so what, time lapse that would be generally regarded by current majority opinion in the High Court as not calling for the giving of a Longman direction.
While that state of affairs continues, it seems to me that the only prudent approach of a trial judge is one that regards any delay between offence and complaint as sufficient to raise for consideration the need for a Longman direction. That consideration should concentrate upon two related factors, namely, the actual lapse of time involved in the particular case; and the actual risk of relevant forensic disadvantage in the particular case. It seems to me that, as matters stand, a trial judge would be well advised to give a Longman direction unless it is possible to conclude reasonably: first, that the particular time lapse is so small that any reasonable mind would regard it as, in context, trifling; and secondly, that the risk of relevant forensic disadvantage would be seen by any reasonable mind as, (to borrow from Mason J in Wyong Shire Council v Shirt [1980] HCA 12; (1980) 146 CLR 40 at 47), 'far-fetched or fanciful'."
