One of the questions I am asked most frequently whenever I give a talk on the General Data Protection Regulation ("GDPR") is whether it is necessary to seek renewed consent from existing subscribers to newsletters and other services. That ties up with something else that has happened over the last few days. I have received several requests to renew subscriptions to newsletters and other online services that I have used for years.
The reason for that most frequently asked question is that art 5 (2) of the Regulation requires data controllers not only to comply with data protection principles that have existed in one form or another in every previous data protection statute as well as the OECD Guidelines on the Protection of Privacy and Transborder Flows of Personal Data and the Council of Europe Convention for the Protection of Individuals with regard to Automatic Processing of Personal Data but also to demonstrate compliance with those principles. The first of those principles is that personal data shall be processed lawfully, fairly and in a transparent manner in relation to the data subject. Art 6 (1) of the GDPR provides 6 grounds for the lawful processing of personal data one of which is that "(a) the data subject has given consent to the processing of his or her personal data for one or more specific purposes" (art 6 (1) (a) GDPR). Data controllers have focused on that ground because it is easiest to prove.
"Where processing is based on consent, the controller shall be able to demonstrate that the data subject has consented to processing of his or her personal data."
"When assessing whether consent is freely given, utmost account shall be taken of whether, inter alia, the performance of a contract, including the provision of a service, is conditional on consent to the processing of personal data that is not necessary for the performance of that contract.
"Where processing is based on the data subject's consent, the controller should be able to demonstrate that the data subject has given consent to the processing operation. In particular in the context of a written declaration on another matter, safeguards should ensure that the data subject is aware of the fact that and the extent to which consent is given. In accordance with Council Directive 93/13/EEC a declaration of consent pre-formulated by the controller should be provided in an intelligible and easily accessible form, using clear and plain language and it should not contain unfair terms. For consent to be informed, the data subject should be aware at least of the identity of the controller and the purposes of the processing for which the personal data are intended. Consent should not be regarded as freely given if the data subject has no genuine or free choice or is unable to refuse or withdraw consent without detriment."
"In order to ensure that consent is freely given, consent should not provide a valid legal ground for the processing of personal data in a specific case where there is a clear imbalance between the data subject and the controller, in particular where the controller is a public authority and it is therefore unlikely that consent was freely given in all the circumstances of that specific situation. Consent is presumed not to be freely given if it does not allow separate consent to be given to different personal data processing operations despite it being appropriate in the individual case, or if the performance of a contract, including the provision of a service, is dependent on the consent despite such consent not being necessary for such performance."
Pausing there, it is clear from paragraph 42 of the recitals that consent does not have to be in writing but it does have to be recorded if it is to be proved. Art 7 (2) indicates that consent can be sought on a form that contains other matter. However, if it is, the part relating to consent must be clear and cover all the purposes for which the data is to be processed. If the data are to be processed for more than one purpose, then the data subject's consent must be obtained separately for each of those processes. Art 7 (3) of the GDPR entitles a data subject to withdraw his or her consent at any time. Data subjects should be advised of their right to withdraw their consent at any time before they give it. It should not be more difficult to withdraw consent than it is to give consent. Where the data controller and data subject have unequal bargaining power, the data controller should avoid using (or even giving the impression of using) its leverage to extract a data subject;'s consent.
Nothing in the GDPR suggests that consent has to be obtained or renewed specifically to comply with the Regulation but any consent that has been obtained in the past must have met the Regulation's conditions. Indeed, paragraph 171 of the recitals states that where processing is based on consent pursuant to the existing law, it is not necessary for the data subject to give his or her consent again if the manner in which the consent has been given is in line with the conditions of the GDPR, so as to allow the controller to continue such processing after the date of application of this Regulation.
"Any part of such a declaration which constitutes an infringement of this Regulation shall not be binding."
In other words, a data controller cannot rely on a data user's consent unless the above as a defence to any administrative action, civil claim or criminal prosecution unless the above conditions have been complied with, On the other hand, if a data subject who has validly given his or her consent subsequently withdraws it, art 7 (3) makes clear that the withdrawal of consent shall not affect the lawfulness of processing based on consent before its withdrawal.
If a data subject is under the age of 16 (or such other age between 13 and 16 that a member state may set) art 8 (1) requires consent to be obtained from the person having parental responsibility for that data subject. Art 8 (2) requires the data controller to make reasonable efforts to verify in such cases that consent is given or authorised by the holder of parental responsibility over the child, taking into consideration available technology.
