Introduction
In 2017, the Australian government surveyed the Australian people on whether they supported a change to the law to allow same-sex marriage. Despite the non-binding nature of the survey, there was a widespread expectation that the government would implement the result. In the end, more than 60 per cent of survey participants voted ‘Yes’. On the day that the result was announced, Prime Minister Malcolm Turnbull declared: ‘The people have voted “Yes” for marriage equality, now it's our job to deliver it’ (Turnbull 2017). A few weeks later, the Commonwealth Parliament amended the Marriage Act 1961 (Cth) to make same-sex marriage lawful.
The marriage survey illustrates one of the curious features of the advisory referendum, or ‘plebiscite’ as the device is often called in Australia.2 The result is not binding on the parliament but may nonetheless be treated as if it is. Lawmakers remain free to respond as they wish, but there is a strong political incentive for the parliament to act in line with the result, as disregarding it could risk a severe backlash from voters. For this reason, some view the plebiscite as ‘effectively binding’ (Gallagher 1996, 246). Viewed in this way, the plebiscite can be seen as a device that empowers citizens and, potentially, weakens parliaments (Suksi 1996; Psycharis 2022, 233).
However, others challenge the idea that plebiscites are politically binding and question their value as a mechanism for citizen participation in the making of policy decisions. They point to examples where advisory votes have been ignored by political actors (Cheneval and El-Wakil 2018). Some view plebiscites as nothing more than official opinion polls given that they provide a mechanism for people to express a view on a policy proposal but deny them the final say (noted by Setälä 1999, 87). And it is said that advisory votes, if anything, empower politicians at the expense of citizens, as political actors remain free to manipulate the results to their own advantage (Cheneval and El-Wakil 2018). On this account, the plebiscite offers an illusion of popular control but preserves the power of political elites.
This chapter investigates which of these two accounts of the plebiscite is most applicable to Australia. It does this by examining the immediate aftermath of the 44 plebiscites that have been held by federal, state and territory governments since federation in 1901.
