7 However, the appellant, in defending his acquittal against the cross-appeal, is entitled to and did argue that the finding by the learned magistrate that the artefacts had been on the site later covered by the levee was against the weight of the evidence and led to an unsafe and unsatisfactory verdict. I think there is considerable substance in this. Mr Stanton was the only witness who asserted that the levee covered the position where the four items were found the previous August. The method of recording their position was extremely unsophisticated. Ms McConnell in some cases measured and in others paced the distance of the four items (as she did of 155 other artefacts around the perimeter of the lagoon although even some of the latter distances were only estimated) from what she took to be its high water mark. However, she acknowledged that the actual water level was lower than the high water mark she claimed to have been able to identify and said that she could not remember if all distances had been taken from the high water mark or the actual water's edge. On the appended plan, she plotted the position of each. According to that plan, the distance between the northern most and the southern most of the four was approximately 115 metres, but even the scale on the plan was, according to unchallenged evidence, defective and the true scale distance was greater. No bearings were recorded. No adequate explanation was given as to how distances between artefacts were determined or how the northern most artefact in this group (item 2) was plotted on the plan in a north-south line by reference to any detailed measurement from a known point. Items 2 and 3 were recorded as 30 metres from the high water mark, while item 4 was 15 metres therefrom and item 15, 20 metres from the high water mark. In evidence not subject to cross-examination, the appellant said that 70 per cent of the fill material for the levee was procured from under high water mark and pushed outwards to form an embankment. He said at the particular stretch of levee, the width of its base was from 3 metres at its lowest end to a maximum of 12 metres at a discontinued fence line relied upon by Mr Stanton as a datum point for the items and that "possibly a third" of the levee bank was inside the high water mark. This meant that the outside edge of the levee would be at most 8 metres from the high water mark well short of the distances measured to each object. It was an agreed fact that the levee was "approximately 500 metres long and up to 20 metres wide". The learned magistrate incorrectly recorded in her Reasons for Judgment that "there was no dispute on the evidence that the levee was approximately 500 metres long and 20 metres wide". Certainly on the prosecution case it was no greater than 20 metres wide. Mr Stanton was not prepared to concede that the inside edge of the levee was below the high water mark. He claimed the earth had been moved above that mark and that in his opinion the position of the levee "was such that it would have been on top of artefacts 2 - 5 in as much as it was my opinion a certain distance from the previous dam level, the water level". He conceded that he did not measure that distance and could not recall if when he visited the site in April 1998 he had with him the plan prepared by Ms McConnell the previous August. He also agreed he made no record of the position of the levee in relation to the artefacts until he had left the area. The uncertain method of recording the position of the objects to begin with, the fact that Mr Stanton only noted their position once previously in August and had not visited the site in the meantime save for the October visit and the imprecision of his identification of their location in April, compared with the appellant's evidence of the width and positioning of the levee could not but create a reasonable doubt as to whether or not the levee was constructed over the sites of items 2 - 5. The appellant was rightly acquitted on count 1, for this reason in any event.
