Withdrawal of consent
16.—(1)  On giving reasonable notice to the organisation, an individual may at any time withdraw any consent given, or deemed to have been given under this Act, in respect of the collection, use or disclosure by that organisation of personal data about the individual for any purpose.
(2)  On receipt of the notice mentioned in subsection (1), the organisation concerned must inform the individual of the likely consequences of withdrawing his or her consent.
(3)  An organisation must not prohibit an individual from withdrawing his or her consent to the collection, use or disclosure of personal data about the individual, but this section does not affect any legal consequences arising from such withdrawal.
(4)  Subject to section 25, if an individual withdraws consent to the collection, use or disclosure of personal data about the individual by an organisation for any purpose, the organisation must cease (and cause its data intermediaries and agents to cease) collecting, using or disclosing the personal data (as the case may be) unless such collection, use or disclosure (as the case may be) without the individual’s consent is required or authorised under this Act or other written law.
