Section 5(4), (5) and (6) make provision for late joiners. Section 5(4) allows the State to join a team which has already been established by other member states. Section 5(5) allows other member states to join a team which has been established by member states including the State. Section 5(6) is a technical interpretative provision which extends the reference to member states which established the team to include those member states which join after initial establishment. This means, in effect, that although a member state may be a late joiner, once it has joined it will be considered as if it had been involved in the initial establishment and its members will be seconded members for the purpose of the Bill.
