{{As of|2017}} only two sovereign states, [[New Zealand]] and the [[United Kingdom]], have wholly uncodified constitutions. The [[Basic Laws of Israel]] have since 1950 been intended to be the basis for a constitution, but as of 2017 it had not been drafted. The various Laws are considered to have precedence over other laws, and give the procedure by which they can be amended, typically by a simple majority of members of the Knesset (parliament).<ref name=lawsintro>{{cite web|title=Basic Laws – Introduction|url=https://www.knesset.gov.il/description/eng/eng_mimshal_yesod.htm|website=The Knesset|date=2016|access-date=7 May 2017}} Article gives information on the procedures for amending each of the Basic Laws of Israel.</ref>

Uncodified constitutions are the product of an "evolution" of laws and conventions over centuries (such as in the [[Westminster System]] that developed in Britain). By contrast to codified constitutions, uncodified constitutions include both written sources – e.g. constitutional statutes enacted by the Parliament – and unwritten sources – [[Constitutional convention (political custom)|constitutional conventions]], observation of [[precedent]]s, [[royal prerogative]]s, [[convention (norm)|customs]] and traditions, such as holding general elections on Thursdays; together these constitute [[British constitutional law]].
