The judiciary (also known as the judicial system or court system) is the system of courts that interprets and applies the law in the name of the state. The judiciary also provides a mechanism for the resolution of disputes. In some nations, under doctrines of separation of powers, the judiciary generally does not make law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case.
In other nations, the judiciary can make law, known as Common Law, by setting precedent for other judges to follow, as opposed to Statutory Law made by the legislature. The Judiciary is often tasked with ensuring equal justice under law.
