The Tongan Constitution is the fundamental legal document that outlines the structure of the government and the rights of the citizens in Tonga. Established in 1875, it serves as the foundation for the country's laws and governance, ensuring a balance of power among the monarchy, the parliament, and the judiciary. The constitution has undergone several amendments, particularly in 2010, which aimed to enhance democratic processes and increase the representation of the people in the Tongan Parliament. It guarantees various rights and freedoms, including freedom of speech and assembly, while also defining the roles of the King and other government officials.
