The purpose of the Australian Democratic Parliament is to convert political inputs into outputs and to be the means through which the will of the people is expressed. Its bicameral structure is intended to enable the sovereignty of a popular government while maintaining and protecting the interests of states; its two chambers have distinct identities but similar powers. The four main functions of Parliament are legislation, representation, accountability and function as a forum for debate. It is common opinion that there has been a decline in parliamentary theses. Proponents of this belief argue that the modern parliament supports the executive rather than scrutinizes it and therefore acts as little more than an electoral college. They say this decline is evident in that it is unable to effectively scrutinize bills, its members are loyal to parties rather than voters, and that it is ineffective in serving as a forum for debate. This essay will examine and evaluate these claims and ultimately conclude whether or not there has been a decline in parliamentary theses. The legislative function requires parliament to initiate, deliberate and subsequently pass legislation. In accordance with its self-image, Parliament should ideally allow legislative proposals to be put forward by both the government and ordinary members; any such bills should then be examined and amended, where necessary, to make them suitable for enactment. The decline of parliamentary theses, however, maintains that Parliament retains this function only formally since in reality it is dominated by party politics. This statement is based on a variety of factors; first, since the government almost always holds the majority in the lower house, it elects the... charter members... individuals who need to be elected and express their opinions. In conclusion, parliament is clearly incapable of carrying out its traditional functions. This is mainly due to the adoption of two-party systems in 1910 which significantly changed the political objectives. Supporters of the decline of the parliamentary thesis therefore argue that, compared to the golden age, parliament has transformed into a rubber stamp of executive will. These critics, however, fail to take into account that previous parliaments were different, not necessarily better, and while it is true that party dominance has reduced opportunities for debate and the ability to enforce ministerial responsibility, it also has strong advantages how to provide the government with a clear set of political powers that it can then defend with an electoral mandate. Furthermore, the two-party system also contributes to the stability of the government.
