1875 Constitution, never colonised, monarchy reformed in 2010

In practice
The 1875 Constitution was granted, not negotiated, and its continuity is the source of Tonga's distinctive legal order. The 2010 reforms were the decisive modern change: the majority of Legislative Assembly seats became directly elected, the Prime Minister is now drawn from the Assembly rather than appointed by the monarch, and executive power shifted substantially to cabinet — though the King retains significant powers, nine seats remain reserved to the nobility, and the monarch's assent is required for legislation. The reforms followed the 2006 Nuku'alofa riots. A rights chapter exists in the 1875 text and is enforceable, but it is briefer and older in style than modern bills of rights.
