Three Seals Law

The Three Seals Law manuscript no. 41, displayed at the Bangkok National Museum.
The seals of the Mahatthai (represented by a rajasiha), Kalahom (a gajasiha) and Phrakhlang (the Bua Kaeo seal) give the law its name.

The Three Seals Law or Three Seals Code (Thai: กฎหมายตราสามดวง; RTGS: Kotmai Tra Sam Duang) is a collection of law texts compiled in 1805 on the orders of King Rama I of Siam. Most of the texts were laws from the Ayutthaya era which had survived the destruction of Ayutthaya in 1767. The compilation remained the working law of Siam until partially replaced by modern law codes in the early 20th century. The texts are an important source for the history of the Ayutthaya Kingdom and legal history in Asia.

Parts of the Three Seals Law are still in force, according to a ruling of the Supreme Court of Justice of Thailand in 1978.[1]
