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
