As of 2011, Meechai was the chairman of Thailand's Law Reform Commission at the Council of State. After another coup d'état in 2014, Meechai—as one of two civilians—was appointed as a member of the junta which calls itself the National Council for Peace and Order (NCPO). After a first military-appointed committee's draft constitution failed, Meechai was appointed chairman of another Constitution drafting committee by the NCPO on 5 October 2015.
