"In the absence of any statutory or other like definition of the word 'eligible', or of the phrase 'persons eligible for appointment or promotion to a vacant position', one is thus cast back to the normal or usual meaning to be attributed to such words or to that meaning as coloured by the context in which they appear. … As a matter of ordinary English usage, the word 'eligible' conveys a notion of 'available', or 'qualified', for whatever it is - as, for example, to be picked for something, to be appointed to do a task - that is in contemplation. In the present case, it seems to me that the appropriate meaning to be given to the word 'eligible' is that of 'qualified' for appointment to the staff or for promotion from one position to another position on the staff of the TAFE Commission. Since the concept of 'qualified' must apply both to those seeking to join the staff and to those seeking to be promoted from one position to another on the staff of the TAFE Commission and since the range of positions to which appointment or promotion might be sought and the range of qualifications required in order that one might properly carry out those duties would inevitably be extensive, it seems to me that the only manner in which one might determine whether or not an applicant is 'qualified', and, thus, 'eligible', is by reference to the nature and statement of duties of the relevant position and the selection criteria set out in any advertisement of, or other form of invitation for applications for appointment or promotion to, the position in question."
33 Hodgson AJA said (at 115-6) -
"It would be wholly impractical for an employer such as the TAFE Commission to assess for itself de novo every aspect of merit of every candidate for a position. If a position requires abilities normally acquired only by the completion of certain processes of learning and of experience, which is in turn normally demonstrated by acquisition of certain qualifications as being in general both pre-conditions of eligibility for the position and also important aspects of merit in relation to the position. Indeed, it may be unreasonable for the employer not to treat the qualifications as being both essential for eligibility and important aspects of merit. That is not to say that the qualifications may be treated as a substitute for the statutory test of merit; but rather that they are both an aspect of merit, and also an important part of the procedure by which an employer can fairly and efficiently address the question of merit.
Turning to the interpretation of s 18, I note that the TAFE Commission Act contains no definition of 'eligible'; and in my opinion, the suggestion in s 18(2) that the candidates whose merit is to be considered are only those 'eligible' for the position cannot be used to introduce some further criterion for appointment beyond that of 'merit' as required by s 18(1). Accordingly, where as here the Commission has laid down criteria for eligibility for a position, a candidate's failure to fulfil those criteria cannot ipso facto disqualify that candidate from appointment: but, for the reasons set out in the previous paragraph, a reasonable approach to the question of merit may mean that the Commission should regard that candidate as ineligible or, if eligible, of less merit than candidates who fulfil the criteria."
34 These passages support that eligibility for appointment to a position may be determined by the determination of the qualifications a person must satisfy the guidelines to be appointed to the position. The qualifications may be determined by regard to the abilities required for proper performance of the duties of the position, and a person will be ineligible for appointment if that person does not possess the qualifications.
35 Kirby P and Hodgson AJA did not regard the guidelines as a definitive determination of eligibility, although both seem to have regarded failure to possess the qualifications as tending to ineligibility. Their Honours did not say what else could determine eligibility. Powell JA saw less significance in the guidelines, and considered that eligibility was to be judged by reference to the nature and statement of duties of the relevant position and the selection criteria set out in the advertisement of, or other form of invitation for applications for, the position.
36 In the present case there was no equivalent to the guidelines in Janson v Scanlon. The only indicator of the qualifications determined by the Commissioner in respect of the positions was the advertisement of 14 December 1998. The advertisement stated a selection criterion of successful completion of the assessment centre for Crime Agencies and an alternative selection criterion of successful completion of the operational supervisor assessment centre. There was nothing in the evidence to suggest that the criteria did not reflect the possession of a qualification required in order properly to carry out the duties of the positions.
37 The appellants' submission was that successful completion of the assessment centre for Crime Agencies could not be made a qualification by which eligibility was determined because the assessment was on a comparative merit basis. Assessment of merit was distinct from eligibility, it was said, and applicants could not be excluded from eligibility by the statement of a qualification which was really just a cut-off point in assessments of comparative merit. Further, it was said, by the definition of "merit" the possession of qualifications determined by the Commissioner was part of merit, and so applicants could not be excluded from eligibility by statement of a qualification which went to make up the applicant's merit.
38 It is necessary to see what was meant by successful completion of the assessment centre for Crime Agencies. This must be gleaned from less than complete evidence before the Tribunal.
39 The information accompanying the advertisement of 14 December 1998, agreed to be common form information at all relevant times, included -
"ASSESSMENT CENTRE PROCESS
Applicants for positions at the rank of inspector or above should note an assessment centre will be a component of the recruitment process for positions at that rank. Unless otherwise specified in the information package, the assessment centre will be the operational manager/supervisor centre currently conducted for duty officers/crime managers.
Progression to the assessment stage of the process is not automatic as an application cull will be conducted.
Those applicants progressing to assessment centre who do not meet the standard of assessment, will not progress to the interview stage.
Applicants who have previously completed the assessment process, whose applications are progressed from the application will not need to complete the assessment centre as previous results will stand. Conversely, results of those previously unsuccessful at the assessment centre will stand for 12 months from the date of assessment.
Details of the assessment centre process are included in the information package."
40 The evidence did not include the details of the assessment centre process. It will be noted, however, that according to the information applicants had to meet a "standard of assessment" in the assessment centre process, that if they did not they would not "progress to the interview stage", and that the results of prior completion of the assessment centre process would stand for the application for the position. If the applicant was successful in the process, it would not be necessary to undergo the process again. If the applicant was unsuccessful, and was unsuccessful within the preceding twelve months, the application would not progress to interview stage. The particular advertisement of 14 December 1998 was more stringent, in that those invited to apply had to have successfully completed one of the assessment centres - future successful completion of an assessment centre was not sufficient. The past assessment centre process was, or at least included, the assessment centre process pursuant to the publication of 4 May 1998 by which the appellants had applied for the assessment centre for Crime Agencies.
41 The publication of 4 May 1998 began -
"Expressions of interest are now sought from officers interested in being assessed for the following chief inspector and inspector positions within Crime Agencies.
The assessment centre used will be identical to that undertaken by duty officer and crime manager applicants … "
