The legal system is based on Roman-Dutch law with South African influences. A five-member Supreme Court, headed by the Chief-Justice has original jurisdiction over alleged violations of fundamental rights guaranteed in the constitution and appellate jurisdiction over other matters. There is a High Court consisting of general and appellate divisions. Below the High Court are regional magistrate's courts with civil jurisdiction and magistrate's courts with both civil and criminal jurisdiction over cases involving traditional law and custom. Beginning in 1981, these courts were integrated into the national system.
