Parliamentary Court of Justice is responsible for judging acts by the President in cases where he or she has been accused of high treason. This Court also has responsibility for judging acts by the Prime Minister of the Cameroon, other members of the Government and other senior officials in cases relevant to state security. Legal traditions Prior to independence, jurisdiction over Cameroon was shared between the United Kingdom and France under a League of Nations mandate issued in 1919. The northern part of the British area became part of Nigeria while the Christian southern part joined with the French area. As a consequence, the country inherited a dual legal system including parts of the Code Napoleon and the common law. However, on 12 July 2005 the National Assembly (Assemblé Nationale) approved a law to harmonize the country's criminal procedure code. In addition, traditional courts still play a significant role in domestic, property and probate. The court system honours tribal laws and customs when these do not conflict with national laws. Prison system The Ministry of Justice became responsible for administering the prison system at the beginning of 2005 taking over responsibility from the Ministry of Territorial Administration of Cameroon. This follows disturbances caused by overcrowding of prisons and long stays in detention without charges of prisons. There were 15,903 people in the prison system as of 1997 representing 115 per 100,000 population. However, the population of the prisons has grown rapidly in recent years. The New Bell prison in Douala was meant to hold 800 inmates but holds 3,100. The International Centre for Prison Studies estimates that Cameroon has the second highest occupancy rate in the world after Barbados with approximately half awaiting trial. The Government has built two new prisons but has not provided enough staff resulting in the establishment of "anti-gangs" of inmates to preserve order. Human rights The preamble of the constitution adopted in 1996 incorporates parts of the Universal Declaration of Human Rights and the African Charter on Human and Peoples' Rights. The Ministry of Justice shares responsibility for administering human rights with the Ministry of Territorial Administration. A person who considers that their rights may have been violated may take their case either to the statutory courts or to the traditional courts. They may also petition the National Committee on Human Rights and Freedoms established in 1990. They may also seek compensation through the courts.
