Israeli law is based mostly on a common law legal system, though it also reflects the diverse history of the territory of the State of Israel throughout the last hundred years (which was at various times prior to independence under Ottoman, then British sovereignty), as well as the legal systems of its major religious communities. The Israeli legal system is based on common law, which also incorporates facets of civil law. The Israeli Declaration of Independence asserted that a formal constitution would be written, though it has been continuously postponed since 1950. Instead, the Basic Laws of Israel (חוקי היסוד, ħuqey ha-yesod) function as the country's constitutional laws. Statutes enacted by the Knesset, particularly the Basic Laws, provide a framework which is enriched by political precedent and jurisprudence. Foreign and historical influences on modern-day Israeli law are varied and include the Mecelle (Hebrew: מג'לה; the civil code of the Ottoman Empire) and German civil law, religious law (Jewish Halakha and Muslim Sharia; mostly pertaining in the area of family law), and British common law. The Israeli courts have been influenced in recent years by American Law and Canadian Law and to a lesser extent by Continental Law (mostly from Germany). The modern judicial system in Palestine, later the State of Israel, was established by a British senior judicial officer, Orme Bigland Clarke, who was appointed by General Edmund Allenby in 1918, following the British conquest. The British military administration of Palestine (1917-1920) was replaced with a civilian one which operated under the Constitution of Mandatory Palestine, enacted through an Order in Council issued by the British monarch in 1922. Britain, which in 1920 received a League of Nations mandate to govern Palestine, implemented the common-law system, except for the jury system. Legal precedents in torts and contracts were borrowed from England, and certain legal areas were codified in order to assure legal certainty.
