- Article 5(3): Member States shall ensure that the storing of information, or the gaining of access to information already stored, in the terminal equipment of a subscriber or user is only allowed on condition that the subscriber or user concerned has given his or her consent, having been provided with clear and comprehensive information, in accordance with Directive 95/46/EC, inter alia, about the purposes of the processing...
- Recital 66 (non-binding): ...Where it is technically possible and effective, in accordance with the relevant provisions of Directive 95/46/EC, the user’s consent to processing may be expressed by using the appropriate settings of a browser or other application.
- In a June 2010 opinion, the Article 29 Working Party contended that in the case of interest-based advertising, at least:
The Article 29 Working Party is of the view that prior opt-in mechanisms, which require an affirmative data subject's action to indicate consent before the cookie is sent to the data subject, are more in line with Article 5(3). In a reference to consent as legal grounds for processing, the Article 29 Working Party recently confirmed these views "The technological developments also ask for a careful consideration of consent. In practice, Article 7 of Directive 95/46/EC is not always properly applied, particularly in the context of the internet, where implicit consent does not always lead to unambiguous consent (as required by Article 7 (a) of the Directive). Giving the data subjects a stronger voice ‘ex ante’, prior to the processing of their personal data by others, however requires explicit consent (and therefore an opt-in) for all processing that is based on consent."
- At a speech in September 2010, Neelie Kroes (European Commissioner for the Digital Agenda) acknowledged the value created by the online advertising sector and signalled that she was “open to all creative ideas” to develop self-regulation that works for the advertising industry. When directly asked, she also said she was "not in favour of opt-in" for interest-based ads.
- Alberto Alvaro, the MEP who drafted the revised ePrivacy Directive, has written that it “does not require websites to obtain prior consent for cookies to be placed on users’ terminals.”
- The Commission’s DG Legal Service has not yet expressed an opinion on whether the revised E-Privacy Directive requires explicit opt-in for interest-based ad cookies.
