Council of Europe, Additional Protocol to the Convention for the Protection of Individuals with regard to Automatic Processing of Personal Data regarding supervisory authorities and transborder data flows (CETS. No. 181) (2001) (full-text).
This document will increase the protection of personal data and privacy by improving the original Convention of 1981 (ETS No. 108) in two areas. Firstly, it provides for the setting up of national supervisory authorities responsible for ensuring compliance with laws or regulations adopted in pursuance of the convention, concerning personal data protection and transborder data flows. The second improvement concerns transborder data flows to third countries. Data may only be transferred if the recipient State or international organisation is able to afford an adequate level of protection.
