"Report on the existence of a global system for the interception of private and commercial communications (ECHELON interception system) (2001/2098(INI))"
1.6. Characteristics ascribed to the ECHELON system
The system known as ECHELON is an interception system which differs from other intelligence systems in that it possesses two features which make it quite unusual:
The first such feature attributed to it is the capacity to carry out quasi-total surveillance. Satellite receiver stations and spy satellites in particular are alleged to give it the ability to intercept any telephone, fax, Internet or e-mail message sent by any individual and thus to inspect its contents.
The second unusual feature of ECHELON is said to be that the system operates worldwide on the basis of cooperation proportionate to their capabilities among several states (the UK, the USA, Canada, Australia and New Zealand), giving it an added value in comparison to national systems: the states participating in ECHELON (UKUSA states9) can place their interception systems at each others disposal, share the cost and make joint use of the resulting information. This type of international cooperation is essential in particular for the worldwide interception of satellite communications, since only in this way is it possible to ensure in international communications that both sides of a dialogue can be intercepted. It is clear that, in view of its size, a satellite receiver station cannot be established on the territory of a state without that states knowledge. Mutual agreement and proportionate cooperation among several states in different parts of the world is essential.
Possible threats to privacy and to businesses posed by a system of the ECHELON type arise not only from the fact that is a particularly powerful monitoring system, but also that it operates in a largely legislation-free area. Systems for the interception of international communications are not usually targeted at residents of the home country. The person whose messages were intercepted would have no domestic legal protection, not being resident in the country concerned. Such a person would be completely at the mercy of the system. Parliamentary supervision would also be inadequate in this area, since the voters, who assume that interception only affects people abroad, would not be particularly interested in it, and elected representatives chiefly follow the interests of their voters. That being so, it is hardly surprising that the hearings held in the US Congress concerning the activities of the NSA were confined to the question of whether US citizens were affected by it, with no real concern expressed regarding the existence of such a system in itself. It thus seems all the more important to investigate this issue at European level.
