The dissertation conducts a comparative analysis of the roles of the Inspectors-General of Intelligence with specific reference to South Africa. The analysis assessed the roles, functions and structures of the office of the Inspectors-General in the following countries: Canada, Australia, New Zealand, the United States of America, South Africa and equivalent institutions in the United Kingdom. The study was based on a review of existing literature and interviews and written responses with some of the members of the Joint Standing Committee on Intelligence, the former Minister for Intelligence Services, LN Sisulu, the head of the intelligence division of the South African National Defence Force, the former deputy Director-General of the South African Secret Service, judge Gordon who is responsible for interception of communications and the current Inspector-General of Intelligence, Mr ZT Ngcakani. The performance of the office of the Inspector General of Intelligence since 1995 indicates that: (a) there were ambiguities in the legal framework for the office of the Inspector-General which led to various interpretations by stakeholders on the functioning of the office; (b) there is still a need to test the impact of the office of the Inspector General on the Services and the public; and (c) the Inspector-General's office requires other oversight mechanisms to complement its functions. / Dissertation (MSS)--University of Pretoria, 2008. / Political Sciences / unrestricted
