The commission came into being after a clash, known as "
Black May", between pro-democracy demonstrators and the military in May 1992 which resulted in numerous casualties. The
cabinet (42:
Prem Tinsulanonda 3 March 1980 – 30 April 1983) passed a resolution in September 1992, to establish a national organization to protect human rights. The national human rights commission was eventually mandated in Article 199 and 200 of the
constitution adopted in October 1997, and formally constituted in July 2001. From its inception to 31 May 2005, it received 2,148 complaints of which 1,309 had already been investigated, 559 were still in the process of investigation, and 209 were in the process of evidence gathering. The complaints covered not only civil and political rights, but also other rights including economic, social, and cultural. As for the "clash" that inspired the NHRCT, on 16 May 2002,
Amnesty International issued a press release noting that ten years later, justice had still not been served. The NHRCT has been receiving a decreasing number of complaints from the public from
FY2003 to FY2015, the last year reported. ==Organization and budget==
