The Constitution of Bhutan (Dzongkha: འབྲུག་གི་རྩ་ཁྲིམས་ཆེན་མོ་; Wylie: 'Druk-gi cha-thrims-chen-mo) was enacted 18 July 2008 by the Royal Government of Bhutan. The Constitution was thoroughly planned by several government officers and agencies over a period of almost seven years amid increasing democratic reforms in Bhutan. The current Constitution is based on Buddhist philosophy, international Conventions on Human Rights, comparative analysis of 20 other modern constitutions, public opinion, and existing laws, authorities, and precedents. According to Princess Sonam Wangchuck, the constitutional committee was particularly influenced by the Constitution of South Africa because of its strong protection of human rights.
