Articles 8 and 9 of the treaty provide for unified control of the management and operation of the tunnel to be exercised by a Channel Tunnel Authority whose members will be drawn from both countries. To avoid certain legal difficulties and complications that would have been involved in setting up a bi-national corporation for this purpose, the device adopted is to establish two national corporations, the British Board and the French Board, whose members, acting together, constitute the authority. The authority acts through the national boards, and the latter are required to comply with the directions given them by the authority. The boards will, each in its own country, represent the authority for legal purposes. This is in Clause 12(2).
