Wisconsin circuit courts
In addition, the courts are constrained from taking action that will encroach on the powers of the legislative or executive branches. Under the separation of powers doctrine, no branch of government may exercise a power of government assigned exclusively to another branch. The purpose of separating powers among the branches of government is to avoid concentration of governmental power in the hands of a new and to give the various branches the ability to check actions by the other branches.
Judiciary of Greece
According to the Constitution, there are three categories of courts: civil courts, penal courts and administrative courts. The supreme court of the civil and penal justice is the Court of Cassation, while the supreme court of the administrative justice is the Council of State. Hence, Greek judges belong to one of these two branches. Consequently, an administrative judge is not entitled to judge a penal or civil case, while a civil judge is entitled to judge a civil or penal case but not an administrative one.
