24 Counsel for the NSW Police submitted that if an error of fact is relied upon, as it is in this case, it must be an error of fact that is not dependent upon evidence within s 327(3)(a) or (b) being adduced in the appeal and that the evidence sought to be identified in the submissions filed by Mr Fleming in support of the appeal was evidence that to be admissible would need to have fallen within s 328(3)(b). Counsel submitted that such evidence cannot be relied upon to indicate demonstrable error on the fact of the record and referred to Pitsonis v Registrar of Workers Compensation Commission & Anor [2008] NSWCA 88 ("Pitsonis").
25 The NSW Police submitted that attempting to cavil with the clinical judgment of the medical assessor is not a demonstrable error on the face of the record. Counsel also referred to Riverina Wines Pty Limited v Registrar of the Workers Compensation Commission of NSW and Ors [2007] NSWCA 149, (2007) 4 DDCR 607 at 609 where Hodgson J said:
"If the latter medical report is from a doctor who gave an earlier report to similar effect, with which the MAC conflicted, the Registrar could well take the view that there was merely an attempt being made to avoid the conclusive affect of the MAC, and that there was no sufficiently realistic prospect of the ground (deterioration) being made out to warrant the appeal proceedings."
26 Mr Fleming submitted that when making the decision whether there was demonstrate error the Registrar was entitled to take into account further evidence under s 327(3)(a) or s 327(3)(b). Mr Fleming submitted that Pitsonis excludes establishing a demonstrable error by reference to evidence being adduced in the appeal that does not fall within s 327(3)(a) or s 327(3)(b).
27 The MAC was issued on 22 December 2008. The report of Dr Heiner did not come into existence until 9 January 2009. Mr Fleming submitted that the report was clearly evidence that was not available before the medical assessment. According to Mr Fleming the Registrar did not determine whether a ground had been made out under s 327(3)(b). He says that that ground is made out if there is additional relevant information, being evidence not available before the medical assessment appealed against or that could not reasonably have been obtained before that medical assessment. Hence, Mr Fleming submitted that the Registrar was bound to find that the grounds under s 327(3)(b) had been made out and says that the Registrar appears not to have considered that ground because she was already satisfied that the ground under s 327(3)(d) had been made out and that it would be futile to remit the matter to the Registrar. Mr Fleming submitted on further consideration the same conclusion would be reached which is that the matter should proceed to a medical appeal panel. While I accept that the delegate did not address s 327(3)(b) in her reasons it does not automatically follow that that ground of appeal had been made out.
28 The NSW Police did not immediately act to challenge the decision of the Registrar but rather it chose to await the outcome of the Appeal Panel. In these circumstances the court should as a matter of discretion decline to grant the relief sought by the NSW Police. In so far as the exercise of this Court's discretion, it is also relevant to take into account that it was Mr Fleming's solicitor who exercised liberty to restore the matter for medical assessment on the basis that maximum medical improvement had been reached and then succeeded in arguing that he had not achieved maximum medical improvement.
29 In so far as s 327(3)(d) is concerned, the phrase "demonstrable error" was discussed by the Court of Appeal in Pitsonis. The thrust of the appellant's argument in Pitsonis v Registrar of Workers Compensation Commission & Anor [2007] NSWSC 50 was described by Malpass AsJ at [29] - [30] as follows:
"Generally speaking, in the present case, it is said that the error in, or inadequacy of, history was, inter alia, of the nature of either a failure to record or accurately record history that was given or a failure to ask relevant questions …
In the present case the initial problem confronting the plaintiff is the difficulty had in the demonstration of such error. There is an evidentiary hurdle which she could not overcome. All that the plaintiff can look to is competing assertions (made subsequent to the certificate) and speculation. The contents of the certificate do not support the assertion of error. In the circumstances the challenge failed at this threshold stage."
30 On appeal in Pitsonis, Mason P (with whom McColl and Bell AJA agreed) explained at [47] - [49]:
"47 The word "demonstrable" means capable of being demonstrated (The Macquarie Dictionary 4th ed, The Macquarie Library Pty Ltd, Australia, 2005, New Penguin English Dictionary 1st ed, Penguin, London, 2000). If the word "contained" in para (d) were read as no more than "have within itself" (Macquarie Dictionary), then it would follow that s327(3)(d) would confer the equivalent of a right of appeal on all grounds subject only to the persuasive burden being carried by the appellant. This would render para (c) redundant and would tend to trespass over the areas addressed in paras (a) and (b).
48 One thing, I think, is clear, namely that the "appeal" to the Appeal Panel is not intended as the opportunity for an application on the basis of fresh evidence tendered without any constraint and/or on the basis of no more than the Appeal Panel being invited to decide the application afresh. I agree with the observations of Basten JA in Vegan at 400[137] when he stated that two factors suggested that the jurisdiction and powers of the Appeal Panel are limited:
"First, if the Appeal Panel's powers were at large, the need to specify grounds of appeal limited to particular categories, would be rendered largely otiose. Second, the Appeal Panel is not a tribunal which has any powers other than those necessary to deal with the appeals in question."
