The court system of First Nation was first established in LY 899, and on 8 Su'yet of that year it was granted authority (by popular vote of the general public) to vote laws into effect. This came largely in response to increased gang activity across The Land, which itself necessitated increased cooperation between different villages' police departments. This cooperation led to a need for standardized laws, whereas in the past all villages had made up their own laws whenever the need arose, by popular vote of its citizens. The law which granted the court system the power to enact laws itself also left that power in the hands of the people, by referendum; though from that point on, such matters could only be voted on by the public once per year, on Election Day (see Holidays of the Land). Talks to establish this new set of universal laws were held primarily in Kurok, with representatives from every village. The court system began comparing all the laws of the various villages, and rewrote them to apply specifically to all villages, thus effectively repealing the old laws. (Some older laws were not included in the rewrites, and were just dropped entirely.) The courts also began passing entirely new laws.
Aside from the duty of standardizing the legal system for the entire world, the courts also had to attend to the normal business of trying legal cases, when anyone stood accused of a crime. Arguments will be made by a defense attorney who tries to prove the innocence of the accused, and by a prosecuting attorney who tries to prove the guilt of the accused. A decision is reached by a judge.
On 8 Win'yet, 905, the court system passed its Final Law, which transferred the power to enact laws to the newly established High Court. From that point on, the court system would often be referred to as the "lower courts." Their duties at this point consist solely of trying legal cases. They are subject to the decisions of the High Court (and decisions of the lower courts can sometimes be overturned by the High Court), and are technically a part of the judicial system, as is the High Court itself, but the lower courts are not a part of the Judicial branch of the World Council. In 913, a second country, the United Villages of the Chaos, was established, as was the sovereignty of Sorret and West Ocean. The UVC and any sovereign villages then began to establish their own court systems, though really the local courts were already in place, and little actually changed, considering the majority of existing laws were accepted by all governments.
