According to Czech Law no. 129/2000 (Law on Regions), which replaced paragraph of the Czech Constitution on higher-level territorial administrative units (vyšší územne-správní celky), the Czech Republic consists of thirteen regions (kraje) and one capital city (hlavní mesto) with regional status since 1 January 2000. The older seventy-three districts (okresy, singular okres) are still recognized and remain the seats of various branches of state administration, such as the judicial system.
