years of Labor governance, and ending an eight-year period for Hodgman himself as Leader of the Opposition. Hodgman then won a second term of government in the 2018 state election, but resigned mid-term in January 2020 and was replaced by Peter Gutwein. In May 2021, the Tasmanian state election was held after being called early by the incumbent Liberal Party, resulting in their return to government and establishment of a one-seat majority. It was also the first time that the Liberal Party had been elected three-times in a row. In April 2022, former deputy premier Jeremy Rockliff became Premier after Gutwein announced his retirement from politics. Politics Tasmania has a number of undeveloped regions. Proposals for local economic development have been faced with requirements for environmental sensitivity, or opposition. In particular, proposals for hydroelectric power generation were debated in the late 20th century. In the 1970s, opposition to the construction of the Lake Pedder reservoir impoundment led to the formation of the world's first Green party, the United Tasmania Group. In the early 1980s the state debated the proposed Franklin River Dam. The anti-dam sentiment was shared by many Australians outside Tasmania and proved a factor in the election of the Hawke Labor government in 1983, which halted construction of the dam. Since the 1980s the environmental focus has shifted to old growth logging and mining in the Tarkine region, which have both proved divisive. The Tasmania Together process recommended an end to clear felling in high conservation old growth forests by January 2003, but was unsuccessful. In 1996, the House of Assembly consisted of 35 seats with 7 seats per each of the five electorates. By the 1998 election, the number of seats had been reduced down to 25, or 5 per each electorate. This resulted in the reduction of the Greens' number of seats from 4 to 1, and increased the proportion of seats held by both the Labor and Liberal parties. This was despite growth in population (five-fold since responsible government) and an increase in the voting percentage required for a majority government. There was also no public consultation, and inquiries at the time had recommended the opposite. The House of Assembly Select Committee in 2020 recommended in its report that the number should be increased again from 25 to 35, arguing that such a small representation would undermine democracy and limit the capabilities of the government.
