Summary
This paper provides an overview of the review and oversight mechanisms in place for law enforcement and security intelligence agencies in eight countries: Australia, Belgium, Germany, New Zealand, Norway, Sweden, the United Kingdom and the United States. The information provided is based on preliminary research, and is subject to further examination of primary and secondary sources.
