Bureaucracy reform has caused a significant change in the criminal justice system in Thailand. Today, laws, legislation and practices are employed in accordance with the United Nations Standards and Norms in Crime Prevention and Criminal Justice. With the endorsement of the 1997 Thai Constitution B.E. 2540, there has been the establishment of new justice agencies for the protection of Thai citizens, such as the Office of the National Human Rights Commission of Thailand and the Office of the Ombudsman. The Thailand Criminal Justice System is now seen as headed in the right direction. The development of laws and legislation pertaining to criminal justice in Thailand and putting the concept of restorative justice into practice is seen as a better way to enhance the justice system in Thailand to the universal standard, particularly the United Nations Standards and Norms. This paper presents a report on the general situation of the criminal justice system in Thailand, the current situation and problems regarding the treatment of offenders, and countermeasures concerning the use and application of the United Nations Standards and Norms in Crime Prevention and Criminal Justice.
