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.
Robert Sternberg
The main three branches of government are the executive branch, legislative branch and judicial branch. People also need to perform these functions in their own thinking and working. Legislative people like to build new structures, creating their own rules along the way. Executive people are rule followers, they like to be given a predetermined structure in which to work. Judicial people like to evaluate rules and procedures, to analyze a given structure.
