Judgment (15 paragraphs)
Background Facts 8 The judgment of Justice Jagot sets out in a comprehensive, chronological manner the background to the relevant decision-making process and the steps taken by all relevant participants up to and including the promulgation of the 2006 Amendment Order. Her Honour's judgment has not been questioned in any way in this respect. It is, accordingly, unnecessary in this judgment to repeat her Honour's findings. It is sufficient to highlight the significant background facts particularly relevant to the determination of the issues that remain in dispute. 9 Pursuant to the Water Act 1912 numerous bore licences had been issued entitling their owners to access groundwater sources. Concern grew during the 1990s that groundwater sources were being depleted and, specifically, that the total amount of groundwater that could theoretically be removed pursuant to extant licences was unsustainable unless entitlements were reduced. The Lower Murrumbidgee Groundwater Sources are one of six distinct areas which were affected in this manner. The process of reducing entitlements affected important commercial interests and impinged upon the reliance which licence holders had placed upon those entitlements when making decisions about investment on their rural properties. 10 In February 2003 the government of New South Wales gazetted the 2003 Plan which proposed to reduce groundwater entitlements on an across-the-board basis to about 52 percent of the pre-existing entitlements. A challenge to the validity of the 2003 Plan was rejected in this Court. (Murrumbidgee Groundwater Preservation Association Inc v Minister for Natural Resources [2005] NSWCA 10; (2005) 138 LGERA 11.) That Plan was not formally commenced. A few months after its gazettal the Commonwealth announced a National Water Plan, which proposed substantial Commonwealth financial assistance to address the problems that had arisen with respect to access to water, including the depletion of groundwater sources. 11 As a result of the Commonwealth intervention, the New South Wales government changed its policy so as to replace the across-the-board reduction with a new policy which recognised actual historical rates of extraction. Instead of an equal percentage reduction of a licence holder's theoretical entitlement under the Water Act 1912, the new policy was to be determined, in large measure, in accordance with the extent to which, in relevant periods identified in the formula, the licence holder had in fact extracted water pursuant to a licence (referred to as the "history of extraction" in the materials). Accordingly, persons, like the present appellants, who, for various reasons, had used a low proportion of their entitlements during the specified periods, would be significantly disadvantaged under the new proposal in comparison with the effect upon them of an across-the-board percentage cut applicable to all licence holders. 12 The basic objective of the 2003 Plan was to establish a sustainable yield in the long term for each water source by identifying an extraction limit which specified in quantitative terms, albeit subject to variation, the total amount of water able to be extracted per year in terms of the calculated recharge, being the quantity by which, as then computed, the source is replenished during a year was directed to ensure that drawing rights would be sustainable in the long term. The 2006 Amendment Order altered the way that objective was to be achieved in the manner I have identified, ie from across-the-board reductions to reductions based on history of extraction. 13 The new policy was carried into effect in the form of a mathematical formula contained in cl 25C of the 2003 Plan, as introduced by the 2006 Amendment Order. The formula provides a basis for computation of the "share component" of the aquifer access licences into which the entitlements under the Water Act 1912 were converted by the 2003 Plan. A share component entitles a licence holder to draw on a specified or computed amount of water. 14 Only four entitlements under the Water Act 1912 are identified in Sch 5 of the 2003 Plan as amended, the exclusion from which is the subject matter of these proceedings. Pursuant to cl 25C(4), the share component is expressed in a quantified total amount of megalitres per year. The sum of these megalitres constitutes, the Court was informed, one and a half percent of the total water that may be extracted. 15 The operation of the cl 25C formula for determining the entitlement involves a computation commencing with a component to secure a minimum allocation of 100 megalitres per year, multiplied by a component derived from the history of extraction. The history of extraction calculation takes account of average extraction multiplied by a quantity composed of the annual average recharge minus quantities for which the plan otherwise provides, such as the volume of planned environmental water, local water utility access licence share components, the volume of domestic and stock access licenses, the volume of entitlements which are less than or equal to 100 megalitres, and the sum of all of the share components specified in Sch 5. 16 The effect of this formula is, accordingly, that any increase in the quantity of water available pursuant to Sch 5 would have resulted in a decrease in the quantity of water available to all other licence holders, save insofar as they are otherwise protected in the formula. This was a zero sum game. 17 The appellants assert that there was a particular "criterion" which was adopted for the purpose of determining which specific licences would be included in what became Sch 5. Schedule 5, and therefore the 2006 Amendment Order and the 2003 Plan as amended, simply lists certain Water Act 1912 entitlement numbers and their associated licences. The so-called "criterion" is not expressed in any way in the 2006 Amendment Order. 18 What the appellants characterised as the "criterion" for inclusion in Sch 5 was identified in the documentation as follows: "Late developer entitlement holders who demonstrate to the regional groundwater verification committee that they had developed their irrigation business based on a proven expectation that the Murrumbidgee Groundwater Water Sharing Plan would be implemented with ' across-the-board' cuts would have their Final New Entitlement adjusted accordingly." [Emphasis added] 19 It was recognised during the course of the formulation of the history of extraction approach that there would be what was called, at first, in the internal documentation, "anomalies" and which was eventually characterised as the identification of "special circumstances". This factor raised the question of how fairly the history of extraction approach would apply to specific cases. 20 For some part of the period of internal development of the new plan, it appears to have been proposed that the "special circumstances" or "anomalous" cases would be dealt with by additional financial compensation. In the event, it appears that, by reason of the fact that only four such cases were identified as deserving of special treatment in this respect, the licence holders involved were in fact given a special entitlement to water, rather than financial compensation. 21 The basic structure of the decision-making process, culminating in a Ministerial submission, was set out by Jagot J: "[124] By 5 August 2004, a body called the Groundwater Adjustment Committee (or GAC) was established to provide advice to the Director-General of the Department and Minister. The genesis of this committee is unclear but it involved numerous Departmental officers, representatives of relevant catchment management authorities, the chief executive of the NSW Irrigators' Council (which I understand to be an industry representative body), a representative of the Commonwealth, and others. The GAC's objectives included considering proposals for methods to reduce entitlements on the basis of history of use. Its functions included providing advice on these potential methods and processes and guidelines for assessing anomalies arising from the methodologies. According to the GAC's terms of reference the catchment management authorities were to be responsible for consulting with water user groups and licence holders about methodologies for reducing entitlements and related assistance. The catchment management authorities were also identified as responsible for reviewing the water sharing plans and making recommendations to the Minister about the plans. The GAC was to assist the catchment management authorities in their allotted tasks. [125] In June 2005 the Commonwealth and NSW Governments announced an Achieving Sustainable Groundwater Entitlements Program (or ASGE program), including a financial assistance package to help water users manage the reduction in their entitlements. [126] By July 2005 at least two other committees had been established, the Groundwater Adjustment Advisory Committee and the Groundwater Adjustment Officials Committee (known as the GAAC and GAOC respectively). The objectives of the GAAC included considering proposals for alternative entitlement reduction methods based on history of extraction or equivalent methods and consequential changes to water sharing plans. Its specific functions included advising the GAOC on these methods and related issues and 'processes and guidelines for assessing special circumstances arising from entitlement reduction and assistance methodology'. Membership of the GAC and the GAAC was similar." 22 In December 2005, as part of a detailed information package about the ASGE programme, it was announced that a ground water verification committee would be established in each region to, inter alia, identify the history of extraction for each licence holder. 23 Furthermore, her Honour said: "[140] On 6 March 2006 the Murrumbidgee Catchment Management Authority issued a media release saying that the Murrumbidgee Regional Groundwater Verification Committee (MRGVC) had been established to review estimates of licence holders' history of extraction where the holder disagreed with the Department's estimate and that the MRGVC would give advice to the Director-General of the Department on this issue consistent with the outcomes of the groundwater assistance package." 24 After the Committees had undertaken their tasks in each of the six groundwater regions, departmental officers prepared a report for the Minister, based on the Committees' Reports, recommending the adoption of the 2006 Amendment Order incorporating, relevantly, Sch 5. 25 The appellants directed attention to the committee processes which led to the ultimate recommendation that Sch 5 take the form that it did. I do not find it necessary to trace the permutations of this process. I am content to proceed on the basis that the Minister accepted the assessment of his advisers, first that in order to qualify for "special circumstances" a licence holder had to establish that investment had been based on the assumption that the across the board cuts approach would be implemented, and second, that the appellants had failed to establish this. 26 As indicated in par [7] above the appellant's complaint is that they did not receive a hearing as to whether this "criterion" should be adopted or as to whether they satisfied it in any event.
