The Article 29 Data Protection Working Party wrote an opinion on the definition of consent. Not everything this Working Party produces is of interest to me, or even understandable (‘too’ legal for mere mortals). I however did find this opinion interesting since it describes when consent is needed from a legal perspective (based on Data Protection and e-Privacy Directives), and it has examples making it relatively easier to interpret. In my work on this area I usually take the user’s perspective on consent (e.g., on consent for the SURFfederatie), and how to enforce this (architectural/technical perspective), but a legal perspective is of course also needed.
The statement in the summary that especially got my attention was that if consent is used incorrectly, the data subject’s control becomes illusory. I couldn’t agree more, of course, consent cannot be used as an excuse, and in some cases a different legeal ground is needed, and that consent should be informed, freely given etc. I however do want to make a point here that even in cases that privacy law requires a different legal ground for data exchange than consent, it does not forbid to additionally ask for consent. I therefore argue that the decision if and how to offer consent should be primarily based on whether users want it.
Below I quote and interpret parts of the opinion that I found most interesting, and further motivate my position on doing consent-even-when-not-legally-needed.
… obtaining consent does not negate the controller’s obligations under Article 6 with regard to fairness, necessity and proportionality, as well as data quality. For instance, even if the processing of personal data is based on the consent of the user, this would not legitimise the collection of data which is excessive in relation to a particular purpose.
Consent is related to the concept of informational self-determination. The autonomy of the data subject is both a pre-condition and a consequence of consent: it gives the data subject influence over the processing of data. However, as explored in the next chapter, this principle has limits, and there are cases where the data subject is not in a position to take a real decision. The data controller may want to use the data subject’s consent as a means of transferring his liability to the individual. For instance, by consenting to the publication of personal data on the Internet, or to a transfer to a dubious entity in a third country, he may suffer damage and the controller may argue that this is only what the data subject has agreed to. It is therefore important to recall that a fully valid consent does not relieve the data controller of his obligations, and it does not legitimise processing that would otherwise be unfair according to Article 6 of the Directive.
Or in my wording: if a data processor has obtained consent then this does not mean the data processor can do whatever he wants with the data, it has to be a reasonable usage of the privacy sensitive data, the data processor still has a liability and last-but-not-least the person has be in a position to really make a decision.
Transparency is a condition of being in control and for rendering the consent.
Or in my wording: without insight there is no actual control.
There is in principle no limits as to the form consent can take. However, for consent to be valid, in accordance with the Directive, it should be an indication.
The form of the indication (i.e. the way in which the wish is signified) is not defined in the Directive. For flexibility reasons, “written” consent has been kept out of the final text. It should be stressed that the Directive includes “any” indication of a wish. This opens the possibility of a wide understanding of the scope of such an indication. The minimum expression of an indication could be any kind of signal, sufficiently clear to be capable of indicating a data subject’s wishes, and to be understandable by the data controller. The words “indication” and “signifying” point in the direction of an action indeed being needed (as opposed to a situation where consent could be inferred from a lack of action).
Or in my wording: consent can be implicit in an action, but not implicit in doing nothing.
Consent can only be valid if the data subject is able to exercise a real choice, and there is no risk of deception, intimidation, coercion or significant negative consequences if he/she does not consent.
In several opinions, the Working Party has explored the limits of consent in situations where it cannot be freely given. This was notably the case in its opinions on electronic health records (WP131), on the processing of data in the employment context (WP48), and on processing of data by the World Anti-Doping Agency (WP162).
Or in my wording: a consent given in a situation where the person did not really have a choice is basically no consent, and another basis for processing the data is needed. I guess the consent could be considered a form of conformation that the person was at least informed, but the opinion did not state that explicitly.
To be valid, consent must be specific. In other words, blanket consent without specifying the exact purpose of the processing is not acceptable.
To be specific, consent must be intelligible: it should refer clearly and precisely to the scope and the consequences of the data processing. It cannot apply to an open-ended set of processing activities. This means in other words that the context in which consent applies is limited.
Consent must be given in relation to the different aspects of the processing, clearly identified. It includes notably which data are processed and for which purposes. This understanding should be based on the reasonable expectations of the parties. “Specific consent” is therefore intrinsically linked to the fact that consent must be informed. There is a requirement of granularity of the consent with regard to the different elements that constitute the data processing: it can not be held to cover “all the legitimate purposes” followed by the data controller. Consent should refer to the processing that is reasonable and necessary in relation to the purpose.
The need for granularity in the obtaining of consent should be assessed on a case-by-case basis, depending on the purpose(s) or the recipients of data.
Actually, this one does not help me much. Completely open-ended consent is of course not valid, but there are many gray zones here … I guess doing a user survey on what users expect what the consent would reasonably include would be an approach, but don’t know if that would hold up in court.
“consent by the data subject (must be) based upon an appreciation and understanding of the facts and implications of an action. The individual concerned must be given, in a clear and understandable manner, accurate and full information of all relevant issues, in particular those specified in Articles 10 and 11 of the Directive, such as the nature of the data processed, purposes of the processing, the recipients of possible transfers, and the rights of the data subject. This includes also an awareness of the consequences of not consenting to the processing in question”
Two sorts of requirements can be identified in order to ensure appropriate information:
• Quality of the information – The way the information is given (in plain text, without use of jargon, understandable, conspicuous) is crucial in assessing whether the consent is “informed”. The way in which this information should be given depends on the context: a regular/average user should be able to understand it.
• Accessibility and visibility of information – information must be given directly to individuals. It is not enough for information to be “available” somewhere.
I do not understand the difference with transparency, but it certainly makes sense that consent needs to be informed. This is in my opinion also very difficult in reality, since users will often not be willing to spent time/attention to be informed. There are trade-offs here. I think in current practise the quality of information requirement is violated with long legal texts that no-one wants to read or is able to understand.
As time goes by, doubts may arise as to whether consent that was originally based on valid, sufficient information remains valid. For a variety of reasons, people often change their views, because their initial choices were poorly made, or because of a change in circumstances, such as a child becoming more mature.This is why, as a matter of good practice, data controllers should endeavor to review, after a certain time, an individual’s choices, for example, by informing them of their current choice and offering the possibility to either confirm or withdraw. The relevant period would of course depend on the context and the circumstances of the case.
This is what we call “timed consent“. I didn’t realize this was a good practise from a legal perspective 
Our primary motivation for introducing timed consent is also different, we did it because people will forget what they consented to, not because they changed their mind or circumstances changed.
What becomes clear in the opinion, is that simply asking for consent is often not enough. There has to be an actual choice, and the data processor has to provide different legal grounds if this choice is not there. This is also argued by this blog post of Andrew Cormack (JANET). Although I, of course, agree with this, I do not think this means that a consent functionality is therefore not beneficial in cases that a different legal ground is needed.
To make this more specific, taking the consent-from-a-user-perspective pilot we did as an example. In this case, in the SURFfederatie. personal information is exchanged between universities and service providers. Some of the provided services a student simply has to use to be able to complete some course. In this case, there is little choice and there needs to be a different legal ground for the data exchange (and I think there is). However, I believe there is added value in still offering a consent question during the login user experience because:
- The users are informed that this exchange takes place, which in my opinion is a goal in itself.
- There are also services that the user does have a choice, and consent is needed as a legal ground to exchange data, and we need a consistent user experience for all services
- Last but not least: users appreciate the consent question, as our research showed (85% in our pilot)
Or to make it as simple as I can make it (repeating my earlier statement): even in cases that privacy law requires a different legal ground for data exchange than consent, it does not forbid to additionally ask for consent. I therefore argue that the decision if and how to offer consent should be primarily based on whether users want it.
