Semi-parliamentary system
Semi-parliamentary system can refer to either a prime-ministerial system, in which voters simultaneously vote for both members of legislature and the prime minister, or to a system of government in which the legislature is split into two parts that are both directly elected – one that has the power to remove the members of the executive by a vote of no confidence and another that does not. The former was first proposed by Maurice Duverger, who used it to refer to Israel from 1996 to 2001. The second was identified by German academic Steffen Ganghof. In a prime-ministerial system, as in standard parliamentary systems, the prime minister can still be dismissed by a vote of no confidence, this however effectively causes a snap election for both the prime minister and the legislature (a rule commonly expressed by the brocard aut simul stabunt aut simul cadent, Latin for "they will either stand together, or fall together"). Like semi-presidential systems, semi-parliamentary systems are a strongly rationalized form of parliamentary systems. After Israel decided to abolish the direct election of prime ministers in 2001, there are no national prime-ministerial systems in the world; however, a prime-ministerial system is used in Israeli and Italian cities and towns to elect mayors and councils. There are two national and five subnational examples of the other type of semi-parliamentarism still in existence today—the national examples of Australia and Japan and the subnational examples of the five bicameral Australian states. Functioning Parliamentary systems originated in constitutional monarchies, in which the government was dually accountable to the parliament and the king: the plurality of opinions of elected assemblies was then balanced by the direction of the monarch. Over time, the power of hereditary monarchs came to be understood as untenable in a democracy, leading many constitutional monarchies to evolve into parliamentary republics, while in the remaining ones the monarch became an increasingly ceremonial figure: regardless of the presence of an elected or unelected head of state, the parliament was thus established as the dominating institution. In their most basic form, parliamentary systems tend to be quite anarchic, as in the well-known cases of the French third and fourth republics. The attitude of parliaments towards governments is essentially oppositive, as elected assemblies are often incapable of taking energetic decisions whose advantages will only be perceived in the future, but whose disadvantages are immediately experienced by the electors. This calls for a strong rationalization of parliamentary systems, such as the one that developed in the United Kingdom, where the hereditary monarch has effectively been replaced by an "elected monarch", namely the prime minister. Being largely based on conventions, the Westminster system cannot be easily replicated in other countries. In his 1956 proposal, Maurice Duverger suggested that France could attain government stability by means of a direct election of the Prime Minister, that was to take place at the same time as the legislative election, by means of a separate ballot paper. The Prime Minister and his supporting parliamentary majority would need
