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,[1] though it has been continuously postponed since 1950.
