Although Lesotho shares with South Africa, Botswana, Swaziland, Namibia and Zimbabwe a mixed general legal system which resulted from the interaction between the Roman-Dutch Civilian law and the English Common Law, its general law operates independently. Lesotho also applies the common law, which refers to unwritten law or law from non-statutory sources, but excludes customary law. Decisions from South African courts are only persuasive, and courts refer to them in formulating their decisions. Decisions from similar jurisdictions can also be cited for their persuasive value. Magistrates' courts decisions do not become precedent since these are lower courts. They are, however, bound by decisions of the High Court and the Court of Appeal. The most powerful court in the Lesotho justice system is the Court of Appeal, which is the final appellate forum on all matters. It has a supervisory and review jurisdiction over all the courts of Lesotho.
