I was privileged last year to be invited to contribute (in a small way) to a study prepared for the EU Parliament by the Geneva-based Democratic Control of Armed Forces centre. The study focues on intelligence agency review and oversight. The mammoth 400 page document is now available here. Its abstract reads:
This study evaluates the oversight of national security and intelligence agencies by parliaments and specialised non-parliamentary oversight bodies, with a view to identifying good practices that can inform the European Parliament’s approach to strengthening the oversight of Europol, Eurojust, Frontex and, to a lesser extent, Sitcen. The study puts forward a series of detailed recommendations (including in the field of access to classified information) that are formulated on the basis of indepth assessments of: (1) the current functions and powers of these four bodies; (2) existing arrangements for the oversight of these bodies by the European Parliament, the Joint Supervisory Bodies and national parliaments; and (3) the legal and institutional frameworks for parliamentary and specialised oversight of security and intelligence agencies in EU Member States and other major democracies.
Interested readers may find the annexes describing (in considerable detail) the review and oversight systems in western democracies particularly useful -- there is lots to learn for Canada from the systems employed by various European countries and Australia.
