23 Mr Flint submitted that there are, in effect, three indications in the text of cl 5.9.13 of TPS7 which suggest that the Commission's determination by approval of a structure plan, where the Council has not adopted the structure plan, does not constitute or amount to adoption of the plan by the Council for the purposes of cl 6.2.1 of the Scheme. First, Mr Flint submitted that the scheme of cl 5.9.13 is that there are two alternative mechanisms by which a structure plan could make its way from the Council to the Commission for its determination. The first mechanism is where the Council forwards a structure plan to the Commission for its endorsement in circumstances where the Council proposes to adopt the plan: cl 5.9.13.7. The second mechanism is where an applicant itself submits a structure plan to the Commission for its determination in circumstances where the Council has not adopted the plan: cl 5.9.13.11. The two mechanisms are alternatives, depending on the attitude of the Council. The latter "is not a de facto right of appeal to the Commission where a structure plan is not adopted by the Respondent".
24 The second indication, according to Mr Flint, that determination by the Commission does not constitute adoption by the Council, is the use of the word "its" before "determination" in subclause 11 of cl 5.9.13. The word indicates two things. First, the determination is on behalf of the Commission, not the Council. Second, it is not the only necessary determination to be made in relation to the structure plan.
25 The third indication, according to Mr Flint, that the Commission's determination does not amount to adoption by the Council, is that the Scheme provides for a right to seek review by the Tribunal "in relation to the local government's failure to adopt a structure plan" after "the applicant has first obtained a determination of the Commission in accordance with clause 5.9.13.11": cl 5.9.13.13. Mr Flint submitted that, if the Commission's determination were the operative decision in circumstances where the Council has not adopted a structure plan, there would be no need for the right to seek review provided for in that subclause, only the right to seek review of the determination of the Commission, which is conferred by subclause 12.
26 Mr McMurdo submitted that the Commission's determination is of the structure plan itself, that is, whether the structure plan is to be adopted for the purposes of the Scheme. If the Commission approves the structure plan, its determination of the status of the plan is "conclusive", and has "final effect for the purposes of TPS7". Mr McMurdo submitted that the legislative purpose is that the Commission has "an overarching role to adopt or approve the structure plan when it is refused" by the Council.
27 Mr Bydder, for the Commission, acknowledged that, on one view, cl 5.9.13 provides two alternative mechanisms for submitting a structure plan to the Commission for its consideration. However, he submitted that "in describing identical activities, one would expect the use of identical words". He contended that the use of different words, namely "endorsement" and "determination", suggests that the Commission is undertaking different activities under each of the two subclauses, not the same activity. He noted that, whereas "endorse" is relevantly defined in the Oxford English Dictionary On-line to mean "to confirm, sanction, countenance" and "to declare one's approval of", the word "determine" is relevantly defined to mean "to bring to an end a dispute, controversy or doubtful matter; to conclude, settle, decide, fix" and "to direct to some end or conclusion; to come to some conclusion".
28 In his oral submissions, Mr Bydder also placed reliance on the use of the expression "an aggrieved applicant" in the provision which permits such a person to submit a structure plan to the Commission for its determination. These words "echo to some extent" the qualification of a person to seek review by the Tribunal of a determination of the Commission: cl 5.9.13.12.
29 Finally, Mr Bydder submitted that, if the construction advocated by WA Plantation Resources and the Commission were not adopted, "the structure plan would be approved for the purposes of part of the Scheme, but not for the purposes of another part of the Scheme". There is "no warrant in the Scheme for this inconsistency".
30 In consequence of these textual indications, Mr Bydder contended that the Commission's determination is sufficient to bring the structure plan into effect without the need for the Council to adopt the structure plan. He submitted that, if the Commission determines that the structure plan should not be approved, the proponent will be entitled to seek review of the Commission's determination. This construction does not render otiose the right to seek a review of the Council's decision under cl 5.9.13.13. The right to seek such review would properly be exercised where both the Commission and the Council decided that the structure plan should not be approved. In that case, the views of both the Commission and the Council would assist the Tribunal in considering the structure plan on review of their decisions.
31 Although aspects of the argument put on behalf of WA Plantation Resources and the Commission are attractive, the argument is ultimately not persuasive. It is correct that the word "aggrieved", which is used to describe the qualification of an applicant to submit a structure plan to the Commission for its determination, is often used in the context of conferring a right to appeal against, or seek review of, an administrative decision. It is used in that context in subclause 13 of cl 5.9.13 and cl 10.11 of TPS7. However, the use of that word does not necessarily indicate that the Commission's determination is to be in relation to the same issue as was the decision which gave rise to the grievance. In the wider context of cl 5.9.13, the word "aggrieved" simply expresses the qualification on the part of an applicant to be able to submit the structure plan to the Commission, where its determination (whether positive or negative) is a necessary condition for the applicant to be able to seek review before the Tribunal in relation to the Council's failure to adopt the structure plan: cl 5.9.13.13.
32 Similarly, although there is logic and attraction in Mr Bydder's submission that the use of different words suggests that the activity that the Commission undertakes under subclause 7 of cl 5.9.13 differs from the activity that it undertakes under subclause 11, the use of different words is, in this case, readily explicable. The word "endorsement" is used in the first subclause in circumstances where the Council proposes to adopt the structure plan. A word having the meaning of "confirmation, sanctioning or countenancing" is apposite in that context. However, the circumstances of submission of the structure plan to the Commission in the second subclause are entirely different. There, the Council has not adopted the structure plan. It would make little sense to use the word "endorsement" where the Council does not propose to adopt the structure plan, and indeed has refused to do so. Read in the context of the clause as a whole, and in particular the subclause which confers a right to seek review in relation to the Council's failure to adopt a structure plan (cl 5.9.13.13), the expression "its determination" means "its determination as to whether it endorses the structure plan if adopted by the Tribunal on review of the Council's non-adoption".
33 As noted earlier, subclause 13 provides that "an applicant shall not lodge an appeal under cl 10.11 [to the Tribunal] in relation to the local government's failure to adopt a structure plan unless the applicant has first obtained a determination of the Commission in accordance with clause 5.9.13.11". WA Plantation Resources and the Commission were unable to meaningfully explain or address this subclause in a manner consistent with their suggested construction of the clause as a whole. The subclause clearly contemplates that there is utility in an appeal (now a review) in relation to the Council's failure to adopt a structure plan, and that "a determination of the Commission", in accordance with subclause 11, is a necessary condition precedent to the lodgement of an appeal. However, if, on the proper construction of the clause, the Commission's determination were, to quote its written submissions, "sufficient to bring the structure plan into effect without the need for the [Council] to adopt the structure plan", there would be no need to confer a right of appeal or review in relation to the Council's failure to adopt the structure plan, much less to impose a condition precedent to such an appeal or review that the applicant first obtain "a determination of the Commission".
34 The words "a determination of the Commission" contemplate either a positive or a negative determination in relation to the structure plan. If the construction advanced by WA Plantation Resources and the Commission were correct, and if the Commission's "determination" were positive, there would be no purpose served by subclause 13. Equally, if the Commission's determination were negative in relation to a structure plan, there would be no purpose served by the subclause, as subclause 12 confers a right to seek review of the Commission's determination. The Commission's argument that subclause 13 is explicable on the basis that, where both the Council and the Commission decide that a structure plan should not be approved, the views of both authorities would assist the Tribunal in considering the structure plan on review of their decisions, is inconsistent with its principal submission that its function of determination amounts to the adoption of the structure plan by the Council. If that were so, there would be no need to seek review of the Council's decision, only of the Commission's determination.
35 The construction advocated by the Council is correct in light of subclause 13. A further, textual indication which supports this construction is that, whereas the Scheme uses the word "adopt" (with an appropriate suffix) to describe the Council's function in relation to a structure plan and the status of an operative structure plan in each of subclauses 7, 8, 9, 11, 13 and 14 of cl 5.9.13, and in subclause 3.1 of cl 6.2.1, it only ever uses the words "endorsed" or "determination" to describe the function of the Commission in relation to such a plan: cl 5.9.13.7, cl 5.9.13.9 and cl 6.2.1.3.1 ("endorsed") and cl 5.9.13.11, cl 5.9.13.12 and cl 5.9.13.13 ("determination"). Had the legislative intention been to confer an overarching function on the Commission, under which, where the Council did not adopt a structure plan, the Commission's determination would make the structure plan operative for the purposes of the Scheme, it would have been anticipated, in this context, that the Scheme would have used the word "adoption" rather than "determination" in subclause 11 of cl 5.9.13.
36 The answer to the second preliminary issue identified at par [5] above is "no". The approval of the structure plan by the Commission did not constitute or amount to adoption of it by the Council. Contrary to the Commission's submission, this does not result in an "inconsistency". It is apparent from subclauses 7, 9 and 13 of cl 5.9.13, and from cl 6.2.1, that the Scheme creates a two-stage process for a structure plan to become operative. It requires both "adoption" by the Council and "endorsement" by the Commission, although the adoption cannot take place until the endorsement. Each stage of the process is necessary, but not sufficient, for the structure plan to become operative. There is, therefore, no inconsistency in the Commission making a positive determination in relation to a structure plan and the Council making a negative determination. The applicant, in such a situation, has a right to seek review by the Tribunal of the Council's non-adoption of the structure plan. Alternatively, WA Plantation Resources submits, the Tribunal has power to adopt a structure plan on behalf of the Council in the course of undertaking a review of the Council's determination of a planning application. I now turn to consider that contention, which is the third preliminary issue identified at par [5] above.
