Butei Law

Japanese Butei Charter

Also referred to as the Butei Charter, these laws were founded by the IADA (Intergovernmental Armed Detective Alliance) (国際武偵連盟 Kokusai Butei Renmei?) govern the actions of Butei across the world. Each country has their own separate articles and provisions, so Butei on overseas assignments adhere to the law of the land their license is from.
