6 Interpretation and application of Act by reference to objects
(1) In the interpretation of a provision of this Act or the regulations, a construction that would promote the objects of this Act or the provision is to be preferred to a construction that would not promote those objects.
(2) In the exercise of a discretion conferred by a provision of this Act or the regulations, the person exercising the discretion must do so in the way that would best promote the objects of this Act or of the provision concerned."
32 The third defendant was bound, secondly, by the procedural requirements of Chapter 14 of the Guidelines which Chapter deals with the topic "Assessment Procedure". The provisions which are now particularly relevant are:
"14.1 In conducting an assessment an assessor may determine the assessor's own procedure and is not bound by the rules of evidence and may inquire into any matter in such manner as the assessor thinks fit.
14.3 The assessor is to act with as little formality as the circumstances of the case permit and according to equity, good conscience and the substantial merits of the case.
14.4 The assessor is to take into account the objects of the Act at all times.
14.7 The assessor is to progress the resolution of the claim as quickly, fairly and as cost-effectively as is practicable.
14.8 The assessor shall determine the way in which an assessment is to proceed and may:
14.8.1 decide the elements of a claim on which oral evidence or oral argument may be submitted, and
14.8.2 direct that evidence or argument be presented in writing, and
14.8.3 direct that submissions be presented in writing, and
14.8.4 determine whether an assessment conference is necessary and the time and place for any assessment conference that is to be held, and
14.8.5 determine whether any other conference is necessary, and
14.8.6 direct the number and/or type of witnesses who can give evidence at the conference."
33 The third defendant was, thirdly, acting as a person who had been appointed to be a claims assessor upon the basis that he was in the opinion of the first defendant "suitably qualified" to hold that appointment.
34 The third defendant had, fourthly, curial guidance in the form of the judgment of Hoeben J of this Court in Zurich Australian Insurance Limited v MAA and Another [2006] NSWSC 845, a decision to which the third defendant was taken by the submissions made to him by the plaintiff. I note in particular and as the third defendant was expressly invited to do, paras 53 and 54 of that judgment:
"53 Against that background the scheme of the Act in relation to exemptions from assessment seems to be tolerably clear. Most claims will be assessed in accordance with Part 4.4 of the Act. There will be some claims which are exempt from assessment, but they will be in the minority and be the exception. Lest such exemptions be granted too freely (and thereby defeat the objects and purpose of the Act) strict requirements are imposed before a claim is exempt from assessment. In the case of an exercise of a discretion by an assessor, that requires the approval of the PCA before a certificate of exemption can issue. It follows that if a party to a claim wished to challenge a certificate of exemption, or a determination that a matter was not suitable for assessment under Part 4.4, it could do so for failure to follow the procedure set in place for the granting of such exemptions from assessment. What is less clear (as has arisen here) is what can be done by a party which is aggrieved because either a certificate of exemption from assessment has not been granted or a determination as to non-suitability has not been made.
54. The scope for intervention by this Court with regard to administrative decision-making is limited. For Zurich to be successful in establishing jurisdictional error it has to bring itself within the principles in Craig v South Australia (1985) 184CLR 163 at 179:
If...an administrative tribunal falls into an error of law which causes it to identify a wrong issue, to ask itself a wrong question, to ignore relevant material, to rely on irrelevant material or, at least in some circumstances, to make an erroneous finding or to reach a mistaken conclusion, and a tribunal's exercise or purported exercise of power is thereby affected, it exceeds its authority or powers. Such an error of law is jurisdictional error which will invalidate any order or decision of the tribunal which reflects it."
35 I am, with respect, in general agreement with his Honour's analysis.
36 Fifthly and finally, it is in my view appropriate to bear in mind, albeit by way of analogy, the following observations of the Court of Criminal Appeal in connection with the examination of a summing up at trial:
"The practice of subjecting a summing-up, after the trial is over, to a minute and detailed textual criticism in the hope of finding something on which to base an argument cannot be too strongly discouraged. Such a practice does not in my opinion assist in the proper administration of justice, and this Court was not called into existence to wrestle with exercises in mental ingenuity of that kind.
.….Every summing up must be regarded in the light of the conduct of the trial and the questions which have been raised by the counsel for the prosecution and for the defence respectively. This Court does not sit to consider whether this or that phrase was the best that might have been chosen, or whether a direction which has been attacked might have been fuller or more conveniently expressed, or whether other topics which might have been dealt with on other occasions should be introduced. ( R v Sorlie (1925) 25 SR 532 at 539)."
37 I can see no reason in principle why those observations should not apply mutatis mutandis to reasons published by a claims assessor in explanation of a particular decision. What is fairly to be expected of the assessor is that there should be available a statement at once simple, succinct and clear by reference to which either an appellate Court or some other Court of competent jurisdiction can test logically and according to correct principle whether the assessor's decision is supported by a process of reasoning that is supportable in law and in fact.
38 The plaintiff makes five separate criticisms of the third defendant's reasons. It is convenient to take them up seriatim.
39 The first criticism concerns para 10(ii) of the reasons. I have previously quoted that at paragraph 16 of this judgment.
