A/HRC/42/43/Add.2 17. Administratively, the country is subdivided into 11 provinces. Each provincial government is headed by a governor and is charged with ensuring the implementation, at the provincial level, of centrally defined government policies and the exercise of administrative supervision over local authorities. There are also elected provincial assemblies. 18. The legal system is based mainly on a civil law structure inherited from the era of Portuguese colonialization. However, legal pluralism also exists, so that formal mechanisms of conflict resolution coexist with customary rules, provided that the latter do not contradict the values and principles enshrined in the Constitution. The Supreme Court is the final appellate court and it has original jurisdiction in the most serious criminal cases. As well as other judicial courts, there is the Administrative Court and there are courtsmartial and customs, maritime and labour courts. The president appoints some Supreme Court judges and others are elected by the parliament. 19. In May 2018, Mozambican lawmakers approved constitutional changes aimed at a decentralization process that would give political parties more power in the provinces, a step that represents a crucial milestone in the efforts to achieving a lasting peace. 20.
