in 2009. On 5 March 1983, the
Australian Labor Party won the
federal election with a large swing. The new prime minister,
Bob Hawke, had vowed to stop the dam from being built, and the anti-dam vote increased Hawke's majority — some federal Victorian seats were notable for having a strong interest in the issue. However, in Tasmania, the vote went against the national trend and the Liberals held all five seats.
Hawke's government first passed regulations under the existing
National Parks and Wildlife Conservation Act 1975, and then passed the
World Heritage Properties Conservation Act 1983, which prohibited Franklin River dam-related clearing, excavation and building activities that had been authorised by Tasmanian state legislation. However, the Tasmanian government ignored both the federal regulations and legislation and continued to order work on the dam. In April 1983 the Australian government sent a
Mirage jet and later an
RF-111, from the Royal Australian Air Force, to undertake a reconnaissance mission over the dam to gather evidence that the Tasmanian Government was not complying with Federal legislation to stop work. The issue was brought before the
High Court with the first day of hearings on 31 May 1983. The government of Tasmania claimed that the federal government had no powers under the
Constitution to pass either the regulations or the legislation. They claimed that as the right to legislate for the environment was not named in the Constitution, and was thus a residual power held by the states, that the
World Heritage Properties Conservation Act 1983 was unconstitutional. The federal government, however, successfully argued that they had the right to do so, under the 'external affairs' provision of the Constitution as, by passing legislation blocking the dam's construction, they were fulfilling their responsibilities under an international treaty (the
UNESCO Convention for the Protection of the World Cultural and Natural Heritage, Australia having signed and ratified that convention and the Franklin River having been listed on it). The Commonwealth government also argued (successfully) that the federal legislation was supported by the constitutional powers of a federal government to pass laws about corporations and about the people of any race (in this case the aboriginal race, whose sacred caves along the Franklin would have been inundated). The resulting court case became known as
Commonwealth v Tasmania. On 1 July 1983, in a landmark decision, the High Court on circuit in Brisbane ruled by a vote of 4 to 3 in the federal government's favour. Judges Mason, Murphy, Brennan and Deane were in the majority and justices Wilson and Dawson with Chief Justice Gibbs were in the minority. This ruling gave the federal government the power to legislate on any issue if necessary to enforce an international treaty and has been the subject of controversy ever since. Justice
Lionel Murphy wrote most broadly of the Franklin Dam decision's broader environmental and social implications in terms of the
UNESCO Convention's
common heritage of humanity principle, stating that "The preservation of the world's heritage must not be looked at in isolation but as part of the co-operation between nations which is calculated to achieve intellectual and moral solidarity of mankind and so reinforce the bonds between people which promote peace and displace those of narrow nationalism and alienation which promote war...[t]he encouragement of people to think internationally, to regard the culture of their own country as part of world culture, to conceive a physical, spiritual and intellectual world heritage, is important in the endeavour to avoid the destruction of humanity." The High Court ruling ended the dam's construction, and the plans have never been revived. On 5 July 1983, a
Huon Pine known as the
Lea Tree, over 2000 years old and about 9 feet (3 metres) across was chainsawed and set alight. Three people who are thought to be the perpetrators were photographed with the tree in the background. This photograph also shows graffiti containing
expletives, which appears to be directed against environmentists on the tree. This was likely done by people who were angry that the project was cancelled. However, dam-building by the Hydro was not finished. The corporation was still able to construct a 'compromise' power development scheme on the nearby
King River and
Henty River to compensate for the loss of the potential power generation from the Franklin scheme. Further on in time, the
West Coast Wilderness Railway - the reconstruction of the old Mount Lyell Abt Railway between
Queenstown and Regatta point, was mainly financed by compensation funds allocated to the Tasmanian Government for the "loss" of the Franklin River or Gordon River dams. ==See also==
