8 Before turning to submissions made in support of the challenge, it is convenient to refer to the appellant's evidence and to some of the medical evidence on the issue, which his Honour took to be critical.
9 The appellant was crossing Marrickville Road holding his infant son in his arms when he was struck by a car. He fell, landing heavily on his right side. The appellant and his son were conveyed by ambulance to the Emergency Department of the Royal Prince Alfred Hospital.
10 The ambulance officer's report included the following history:
"Painful r scapula. C/T. Pedestrian hit by car. C/A family in Medical Centre.

11 The history recorded in the hospital's Emergency Department notes was:
"R shoulder/hip pain, no other complaints.
…

12 The appellant's evidence in chief of his symptoms immediately after the accident was (Black 13.T-14.H):

A. Yes.
Q. When you saw Dr Bourton what problems were you having at that time?
A. Once it cooled down my back started hurting regularly and my neck was still stiff and I still had sharp pains in my chest and right shoulder."
13 The cross-examination on this topic was (Black 29.I-L):
"Q. And I suggest that you said you didn't have any neck pain at that time?
A. Yeah I didn't at the time, no.
Q. I suggest that you didn't suggest either to the ambulance officers or to the people at the hospital that you had back pain?
A. Not at the time no."
14 The day after the accident, the appellant attended a general practitioner, Dr Bourton. Some of Dr Bourton's clinical notes were tendered by the respondent, but these did not include any notes of the attendance on 3 August 2001. The appellant's usual general practitioner was Dr Rothonis. Dr Rothonis' clinical notes were in evidence. Parts of them are indecipherable, but they included the following entries:
"6.8.01 MVA 2.8.01…. "C6 C7"
…
7.8.01 MVA on 2.8.01 -

15 Dr Rothonis referred the appellant to Dr Youssef, a rheumatologist. Dr Youssef recorded that the appellant had low back pain. On 13 September 2001 he ordered an MRI scan of the lumbar spine and sacral regions. (Blue 18.P-Q) Dr Youssef's treatment of the appellant was for pain in the right shoulder, which he considered to be secondary to rotator cuff tendonitis. Dr Youssef referred the appellant to Dr Watson, a neurologist. Dr Watson doubted the existence of any serious neurological problem. (Blue 240.E)
16 In November 2002, the appellant attended Dr Marinkovich, complaining that he was not getting any better after the accident on 2 August 2001. In a report dated 2 June 2003, Dr Marinkovich, a Fellow of the Royal Australian College of General Practitioners, noted that the MRI of the lumbosacral spine carried out on 5 December 2002 showed a T11/12 disc protrusion and that he had referred the appellant to Dr Mahony, an orthopaedic surgeon, for assessment and treatment. Dr Marinkovich's report supported the view that the appellant's discal injury was causally related to the accident. Dr Mahony's reports also supported this conclusion. The appellant was referred to Dr Steel, neurosurgeon, whose reports also support the causal link, as does the report of Associate Professor Yeo, an orthopaedic surgeon.
17 Dr Matheson, a consultant neurosurgeon retained by the respondent, considered that the bulge at T11/12 was an old chronic disc change, which was in any case asymptomatic. In his opinion, the appellant has no disabilities arising from the accident. Dr Sachdev, an orthopaedic surgeon, considered that the appellant's symptoms were associated with a great deal of functional overlay. (Blue 249.S)
18 Dr Dowda, who assessed the appellant for the Medical Assessment Service, commented that there is considerable doubt raised as to the nexus between the accident and the discal change identified by imaging studies. (Blue 301.H)
