The independent judicial branch is based upon the English model and consists of a Supreme Court of Appeal, a High Court divided into three sections (general, constitutional, and commercial), an Industrial Relations Court and Magistrates Courts, the last of which is divided into five grades and includes Child Justice Courts. The judicial system has been changed several times since Malawi gained independence in 1964. Conventional courts and traditional courts have been used in varying combinations, with varying degrees of success and corruption.
