The will of limiting power of those who dominate societies and the theory of seperation of powers did lead to establishment of modern state. Montesquie explained the formation of legislative, executive and judiciary powers which have impact on administartion and relation of those with each other, in his book called “The Sipirit of the Laws”. From this point of view, the degree of the relation among the powers lead to the name governmental systems differently, so far. The judicial power among the powers is held in separate place within this relationship. Judiciary has close relation with legislative and executive powers in all governmental forms. But Constitutional Courts, found after II. World War to limit legislative and executive powers, and Administrative Courts of Continental Europe States implementing dual judicial system, the both courts have functions in ruler relations. The existence of these relations do not change governmental form. There are courts established in accordance with geographic rudiments in all states with different names. Consequently judicial power, which does not have any impact on establishment of governmental systems, is not included to this research.
