Arnold v Minister Administering the Water Management Act 2000 (No 6) [2013] NSWLEC 73

Arnold v Minister Administering the Water Management Act 2000 (No 6) [2013] NSWLEC 73

The Plan and Amending Regulation are not invalid. The Minister was under a duty to have regard to sustainable yield and socio-economic impacts but was not required to rely on a 'sound and reliable' hydrogeological numeric model; the approach adopted was within the latitude permitted by the Act. The Plan's extraction limit was not irrational or manifestly unreasonable in light of expert advice and available information. Socio-economic impacts were adequately considered without the need for a formal or farm-by-farm study. No acquisition of property contrary to s 51(xxxi) occurred. The form of the Plan satisfied statutory requirements. The proceedings are thus dismissed.
