The comprehensive legal information system is a database that organically integrates information such as precedents, laws, and legal documents operated and managed by the Supreme Court, the Constitutional Court, the National Assembly, the Ministry of Government Legislation, and the court library, and is serviced inside and outside the court through the Internet. The Court Library is a center that provides comprehensive legal information. Data such as precedent data and legal documents from the Supreme Court, courts at various levels, and the Constitutional Court are collected and processed and loaded into the system. In July 2013, the new comprehensive legal information system, co-developed by the court library and Government Computer Center of the National Court Administration, has further improved its functions, such as improving the quality of search services and providing stable services.
