According to Adat Nagari (KAN) which consists of Adat functionaries. The existence of KAN has been upheld by Perda Sumatera Barat No. 13 1983 and the Circulation letter 1985 of higher court of Sumetera Barat. Indonesian Supreme Court has also upheld the existence of Adat law. In its decision No. 1644 K/Pid/1998, May 15, 1991 Supreme Court turned down the charge of prosecutor with the argument that the accused has been tried and punished according to Adat Law.
