Goseibai Shikimoku

The Goseibai Shikimoku (御成敗式目) or the Formulary of Adjudications was the legal law of the Kamakura shogunate in Japan, promulgated by third shikken Hojo Yasutoki in 1232. It is also called Jōei Shikimoku (貞永式目) after the era name.

Before enacting the Goseibai Shikimoku, the Kamakura shogunate conducted trials without formal laws. After the Jokyu Incident, an increasing number of land disputes between its vassals, aristocrats and peasants made fair trials indispensable. Thereafter Hojo Yasutoki compiled the outline with 51 article headings and 13 Hyojoshu (councilors) completed it.

Supplementary articles to the Goseibai Shikimoku, called Tsuika (追加), were issued afterward. The Muromachi shogunate also adopted the Goseibai Shikimoku as the basic law. The Goseibai Shikimoku was repealed during the Edo period, but was widely used as a textbook for writing in temple schools.
