The Supreme Court of Hawaii is the highest court of the State of Hawaii in the United States. Its decisions are binding on all other courts of the Hawaii State Judiciary. The principal purpose of the Supreme Court is to review the decisions of the trial courts in which appeals have been granted. Appeals are decided by the members of the Supreme Court based on written records and in some cases may grant oral arguments in the main Supreme Court chamber. Like its mainland United States counterparts, the Supreme Court does not take evidence and uses only evidence provided in previous trials.
