32 Ms Rosen says that Dove's Plan 1880 (c 1879) gives an accurate picture of the buildings abutting the laneway. This is probably correct. The Plan, which coincided with the Sydney Corporation Act of 1879 labels the lane as a 'Right of Way'. Dove's second Plan also appears to show an open access to commercial premises at the rear off the T of the lane. These premises front York Street. Dove's second plan is clearly an update of the first and appears to be current to 1879.
33 Ms Rosen then turned to examine the Council records, which she says provide the 'most convincing evidence of the private use' of the lane. She refers, in particular, to the rate assessment books, especially 1861 and 1862. These had also been relied on by Dr Fitzgerald, the Council Historian. Both historians referred to two ratings in 1861 described as 'off' George Street. Ms Rosen said that the 'off' George Street references could be the result of old buildings being utilised prior to their demolition and prior to the actual formation of the lane defined in the 1860 Deed of Partition. Again, I can see no basis in the material for such a conclusion. Indeed, if any inference is available to be drawn from the use of the word 'off', it is more likely to be that of Dr Fitzgerald to the effect that there were rateable buildings off the lane behind George Street. This portion of Ms Rosen's opinion seems to be no more than conjecture.
34 Reference is then made by Ms Rosen to the notation in the 1863 rate book - 'Through to York Street'. This, she says, meant no more than the rate assessment was included in the York Street building at the rear. I am not sure that this inference is open but even if it is, it cannot support her conclusion which follows:
It also lends support to the view that the actual formation of the lane occurred in c 1862.
35 I am unable to see any logical connection. The opinion does not appear to flow from the material relied on.
36 Ms Rosen continues that the 'overall evidence strongly supports the redevelopment view'. Her report then proceeds to what she describes as 'the most significant' source of evidence, being an 1896 document of the City Engineer. Ms Rosen says that this document identifies the subject laneway as being gated and part paved with sandstone at private expense. She relies upon the reference to the gate in this 1896 document to demonstrate that the lane was privately owned and maintained at that time and, according to her, it 'implies' that this was established practice.
37 However, an examination of the particular document admitted into evidence provides no justification for her opinion.
38 The document is headed 'Brisbane Ward' 'Private Ways'. It contains columns from left to right starting with reference book numbers, the name of the lane, plan number, 'from' and 'to' and 'remarks'. The relevant entry, according to Ms Rosen, is the fifth from the top.
39 Unlike the other entries, this lane has no reference book number, that column being empty. It describes an unnamed lane situated on 'W side of George Street'. The remarks column states 'Part running North and South. Sandstone Paved at Private Cost. Remainder unimproved 12 feet wide. 1 Gully Gates across this lane'. The word 'Gates' is an interpolation between 'Gully' and 'across'.
40 However, far from providing the 'most significant source of evidence', there was, in my opinion, no evidence before Young J which linked the lane in the 1896 document to the subject lane. George Street was a long street and doubtless had many lanes off its western side. The 1896 document provides no evidence that the subject lane had gates in 1896, as Ms Rosen opines. Nor does it provide any evidence that the subject lane was privately used, as she claims.
41 Leaving aside that the 1896 Engineer's document was compiled 17 years after 1879, the subject lane was described as being 10 4½ in the 1860 Deed and fairly consistently described at or about this width in later plans, and not 12 wide. Indeed, no plan refers to the subject lane as being 12 wide. This discrepancy reinforces the likely conclusion that the lane referred to in the Engineer's report of 1896 is not the subject lane but another lane off George Street. There is just no cogent evidence to link it to the lane in question.
42 In my opinion, a close analysis of Ms Rosen's report and the documents upon which it purports to be based, leads to the conclusion that her opinions are not wholly or substantially based on her specialised knowledge. Young J was entitled to reject her evidence on this basis.
43 Should I be wrong, it would follow that the evidence of her opinion was admissible. However, for the reasons discussed above concerning the plausibility of her conclusion, the report would carry little weight. Its rejection would not occasion a substantial wrong or miscarriage because it would not lead to a different result. Assuming the report was wrongly rejected, a new trial should not be ordered.
