On June 7 1839 the Hawaiian Declaration of Rights was signed.
Proclaimed by Kamehameha III (Kauikeaouli) on June 7, 1839, the Declaration of Rights—often called Hawaiʻi’s first Bill of Rights—affirmed natural rights for both the makaʻāinana (people) and aliʻi (chiefs), including protection of life, limb, and property and freedom of worship. It marked a shift from chiefly rule by custom to governance under written law, laying the groundwork for the 1840 Constitution and later legal reforms. Issued amid growing foreign pressure and missionary influence, the declaration signaled the Kingdom’s intent to meet recognized standards of law among nations. – Hawaiian Cultural Association.
On October 8 1840 the Hawaiian Constitution was enacted.
The Constitution defined the duties of each branch of government. Civilly, the laws embraced the usual rights and duties of the social relations between the three classes of people, and initiated the internal development of the country with the promotion of industry and commerce.
His Majesty King Kamehameha III voluntarily relinquished his absolute powers and attributes, by promulgating a constitution that recognized three grand divisions of a civilized monarchy; the King as the Chief Executive, the Legislature, and the Judiciary.
In these laws, the fundamental basis of landed tenure was declared, and cultivation of the soil, under a feudal tenancy.
