Unwritten Constitutions: Britain, Israel, New Zealand

Three democracies operate without a single entrenched constitutional document. Britains constitution sprawls across statutes like Magna Carta, the Bill of Rights 1689, and Parliament Acts, plus conventions and royal prerogative.

Israel builds piecemeal through Basic Laws since 1958, with the Supreme Court converting them into review grounds in 1995. New Zealand relies on ordinary statute, the Treaty of Waitangi, and convention under parliamentary sovereignty.

The lesson, flexibility and political restraint substitute for entrenchment, until crises like Brexit prorogation or Israels 2023 judicial fight test the limits..
