Three years later, while “good governance” was widely accepted in the Thai public sector, “Black May” (Phruetsapha Thamin) – a common name for the 17-20 May B.E. 2535 (1992) popular protest in Bangkok against the government of General Suchinda Kraproyoon, led to a major demand to re-write the constitution which was completed in 1997 (Pasuk Phongpaichit, 2001: 1). The promulgation of The Constitution of the Kingdom of Thailand B.E. 2540 (1997) was called a “revolution in Thai politics”. The constitution showed a bold attempt at conferring greater power to the Thai people and decentralizing government. After that, laws and regulations relating to the reform and restructuring of government were continuously promulgated.
