Drafted by law lecturers from Chulalongkorn University (CU), the constitution was enacted by the National Council for Peace and Order (NCPO), a military junta led by General Prayut Chan-o-cha which staged a coup d'état against the caretaker government on 22 May 2014. Without public consultation, King Bhumibol Adulyadej assented to and signed the constitution on 22 July 2014. The constitution came into force on that day and replaced the 2007 constitution.
