This Chapter deals with the transfer of personal data to third countries or international organisations, as follows—
sections 73 to 76 set out the general conditions that apply;
section 77 sets out additional conditions that apply in certain cases where the intended recipient of personal data is not a relevant authority in a third country or an international organisation (see section 73(4)(b));
section 78 makes special provision about subsequent transfers of personal data.
In this Chapter, "relevant authority", in relation to a third country, means any person based in a third country that has (in that country) functions comparable to those of a competent authority.
