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.
Court system of Canada
These courts (as listed below by province and territory in alphabetical order) exist at the provincial and territorial levels. The superior courts are the courts of first instance for divorce petitions, civil lawsuits involving claims greater than small claims, and criminal prosecutions for indictable offences ("i.e.", felonies in American legal terminology). They also perform a reviewing function for judgements from the local inferior courts and administrative decisions by provincial or territorial government entities such as labour boards, human rights tribunals and licensing authorities.Furthermore, some of these superior courts (like the one in Ontario) have specialized branches that deal only with certain matters such as family law or small claims. To complicate things further, the Ontario Superior Court of Justice has a branch called the Divisional Court that hears only appeals and judicial reviews of administrative tribunals and whose decisions have greater binding authority than those from the "regular" branch of the Ontario Superior Court of Justice. Although a court, like the Supreme Court of British Columbia, may have the word "supreme" in its name, it is not necessarily the highest court in its respective province or territory.
