In pursuance of the recommendations of the Santhanam Committee on Prevention of Corruption, the Government of Tamil Nadu constituted the Directorate of Vigilance and Anti-Corruption in 1964 and the State Vigilance Commission in 1965. A Vigilance Commissioner heads the Vigilance Commission. He advises the Government on the major administrative problem of prevention of corruption in Public Services in general and the manner in which an individual case of corruption that is brought to light should be dealt with.

               The commission has jurisdiction and power to undertake an enquiry or cause an enquiry/investigation to be made on any information that a Public Servant has exercised or refrained from exercising his powers, for improper or corrupt purposes. It also has powers to call for any information from any Department or Undertaking of the State Government or from any Public Servant on matters within its jurisdiction.

              The Government of Tamil Nadu set up the Directorate of Vigilance and Anti-Corruption (DVAC) as a separate Department as a first organised measure towards tackling corruption in public administration. The DVAC comes under the administrative control of the Government in Personnel and Administrative Reforms (N) Department. With regard to matters of enquiry and investigation against Public Servants, the reports on the result of enquiries/investigations are sent to the Vigilance Commissioner for further action .
