3 The background to the proceedings at first instance and on appeal is conveniently and accurately set out in the appellant's written submissions. Since 1950, electricity generation in New South Wales was provided by the Electricity Commission of New South Wales, which became Pacific Power. Pacific Power was exclusively, until 1996, involved in the operation and ownership of all power stations throughout New South Wales. Pacific Power, until 1995, also operated the electricity transmission network and various coalmines that provided coal for the generation of power.
Restructuring of Pacific Power
4 In 1995, the New South Wales State Government decided to restructure Pacific Power through the transfer of many of its assets to other SOCs to comply with federal competition requirements. From 1995, Pacific Power was progressively restructured until 1 July 2003 at which time the appellant succeeded Pacific Power. The restructuring occurred as follows:
(a) In 1995, the transmission assets of Pacific Power, namely the power lines and substations were transferred to TransGrid, an SOC that primarily transmitted electricity between the power station and the on-seller (e.g., EnergyAustralia).
(b) In 1996, Delta Electricity and Macquarie Generation were formed as SOCs to take-over Pacific Power activities, and to participate in the new electricity market for electricity.
(c) As at 1 July 2000, Pacific Power's business consisted of:
(i) power generation assets (including coal, wind, gas and hydro generation plants);
(ii) power station operations & maintenance (Pacific Western);
(iii) an energy consulting business, Pacific Power International ("PPI");
(iv) coal mining (Powercoal); and
(v) research & development (Pacific Solar).
(d) On 2 August 2000, the power generation and power station operations maintenance businesses within Pacific Power were transferred to an SOC, Eraring Energy. The coal mining was sold on 6 August 2002.
(e) In December 2002, a Memorandum of Understanding was negotiated between the Labor Council, unions affiliated with the Labor Council and the State Government. The MOU dealt with the entitlements and benefits that would be available to employees of Pacific Power, arising out of the sale of PPI and the closure of Pacific Power.
(f) As at February 2003 Pacific Power's workforce was approximately 335. In February 2003, the energy consulting business, PPI, was sold to Connell Wagner and all assets and contracts of PPI were transferred to Connell Wagner. As part of the divestiture, approximately 122 employees accepted the Pacific Power voluntary redundancy package and obtained permanent positions with Connell Wagner. Furthermore, the employees who obtained employment with Connell Wagner obtained membership with a mirror superannuation scheme (the EISS) to that they had previously been entitled to. Some ninety other employees accepted the Pacific Power Voluntary Redundancy Package and exited the organisation on 11 February 2003. Some 51 other employees elected to take voluntary redundancy at a later date.
Creation of appellant
5 As we have noted, the appellant was a special purpose corporation. It was created by virtue of the Pacific Power (Dissolution) Act 2003. Pursuant to s 6 of that Act the objectives of the appellant were as follows:
(a) to manage its assets, rights and liabilities effectively and responsibly;
(b) to operate at least as efficiently as any comparable business;
(c) to minimise the risk of exposure of the State arising from its activities; and
(d) to achieve the efficient and timely winding up of residual business activities.
