"Sub-section 420(1) directs the RRT [the Tribunal] 'in carrying out its function under [the] Act ... to pursue the objective of providing a mechanism of review that is fair, just, economical, informal and quick'. A requirement that the RRT pursue an objective of providing a mechanism of review satisfying such a general description is not, in my respectful opinion, a requirement that it observe a procedure in connection with the making of a particular decision, with which para 476(1)(a) is concerned.

> This view gains support from four more specific considerations. First, the objectives referred to in sub-s 420(1) will often be inconsistent as between themselves. In particular, a mechanism of review that is 'economical, informal and quick' may well not be 'fair' or 'just'. It is difficult to accept that the legislature intended in para 476(1)(a) to provide a ground of review where a mechanism of review in its application to a particular case, although 'fair' and 'just', was not 'economical', 'informal' and 'quick'. Similarly, I do not think that the legislature intended by para 476(1)(a) to afford a ground of review wherever the RRT provided a mechanism of review which, in its application to a particular case, was 'economical', 'informal' and 'quick', but which might be considered to be somewhat less than 'fair' and 'just' in some respect.
>
> The second consideration is derived from the nature of non-observance of the supposed 'procedure' laid down in sub-s 420(1). Non-observance would be, for example, a 'failure to pursue the objective of providing a mechanism of review that is fair' or a 'failure to pursue the objective of providing a mechanism of review that is economical'. The nature of the complaint made in a particular case might make relevant evidence of the RRT's staff and financial resources and its internal organisation and practices. A mere conclusion that a mechanism of review in its operation in a particular case did not satisfy one or more of the epithets in sub-s 420(1), would not necessarily establish that the RRT had not been pursuing the specified objective. The difficulty, perhaps practical impossibility, of proving a failure to pursue that objective in some cases suggests that the requirement of sub-s 420(1) was not intended to fall within the ground of review described in para 476(1)(a).
>
> The third consideration is founded on para 476(2)(a) the terms of which were set out earlier. It will be recalled that that paragraph provides that a breach of the rules of natural justice is not grounds upon which an application may be made under sub-s 476(1). If sub-s 420(1) requires observance of a 'procedure' for the purpose of para 476(1)(a), in so far as it refers to a 'fair' and 'just' mechanism of review, it must refer to 'procedural fairness' - an expression synonymous with 'natural justice'[138]. But para 476(2)(a) provides expressly that breach of the rules of natural justice is not a ground of review. This suggests that the legislature did not intend the 'procedures' of para 476(1)(a) to embrace the standards which sub-s 420(1) requires the RRT to pursue.
>
> There is another argument based on para 476(2)(a) that leads to the same result. The general law notion of natural justice comprises the 'impartial tribunal' requirement (the 'bias rule') and the 'fair hearing requirement' (the 'hearing rule')[139]. While para 476(2)(a) makes clear that these requirements do not provide the basis of a ground of review, para 476(1)(f) provides that actual bias is such a ground, while para 476(1)(a) and para 425(1)(a), taken together, have the effect that a failure to give a genuine opportunity to appear before the RRT to give evidence, is also such a ground. This suggests that the legislature turned its mind to the twin requirements of natural justice and intended that para 476(1)(f) and para 425(1)(a) should occupy the field that would otherwise be occupied by the rules of natural justice. It will be clear that I do not agree that the expression in para 476(2)(a), 'the rules of natural justice', is to be read down in some way so that it refers to those rules only in so far as they depend on the general law, and does not detract from any generally expressed requirement of the Act which might otherwise be thought to have the effect of mandating observance of those rules.
>
> The fourth consideration derives from the Explanatory Memorandum which accompanied the Migration Reform Bill 1992. That Memorandum makes clear that s 476 was intended to introduce a regime of limited grounds of review which were 'certain' in their meaning[140]. To permit review on the ground that a mechanism of review is not 'fair' or 'just' is discordant with that intention.
>
> For all the foregoing reasons, I think that the better view is that sub-s 420(1) does not lay down a procedure required to be observed in connection with the making of a decision by the RRT. Before parting with sub-s 420(1), however, I make the following further observation. It should not be thought that all non-observances of statutory directives addressed to a public body must give rise to a civil remedy. Statements of broad objectives to be pursued afford a paradigm illustration of statutory commands which are not intended to generate a private right of action. An example is found in s 9 of the Disability Services Act 1992 (Qld) which was considered in Criminal Justice Commission v Queensland Advocacy Incorporated[141]."
