Part 3: Law enforcement processing Chapter 5: Transfers of personal data to third countries etc Section 72: Overview and interpretation
The transfer of personal data to a third country (as defined in section 33(7)) or to an international organisation should only take place if necessary for a law enforcement purpose, and when the controller in the third country or international organisation carries out functions comparable to those of a competent authority within the meaning of section 30, (except in the case of section 77 which provides for the transfer of data in specific circumstances to a person who does not carry out such functions).
	Where personal data is transferred from the UK to controllers, processors or other recipients in third countries or international organisations, the level of protection of individuals provided for in the UK by Part 3 should not be undermined, including in cases of onward transfers of personal data from the third country or international organisation to controllers or processors in the same, or in another, third country or international organisation.
