CNIL’s crackdown on non-compliant cookie banners

The French Data Protection Authority, known as the CNIL (Commission Nationale de l’Informatique et des Libertés), recently issued a formal notice to multiple website publishers. The CNIL warned that their cookie banners fail to comply with France’s data protection laws, specifically Article 82 of the French Data Protection Act.

Publishers have been given a tight one-month deadline to address these violations or face significant penalties. This move is part of a broader effort to combat “dark patterns”—design tactics that manipulate users into consenting to cookies without genuine choice.

What is the CNIL?

The Commission Nationale de l’Informatique et des Libertés (CNIL) is France’s independent regulatory body tasked with ensuring the protection of personal data and upholding privacy rights. 

Known for its rigorous enforcement of privacy laws, the CNIL has been at the forefront of ensuring cookie consent compliance with the General Data Protection Regulation (GDPR) and the ePrivacy Directive. It regularly audits and issues fines to organizations failing to meet data protection standards.

What are dark patterns in cookie consent banners?

Dark patterns are manipulative design practices used to nudge website (or app) users toward specific actions, such as accepting cookies. These tactics undermine transparency and informed consent, violating data protection principles.

Examples of dark patterns in cookie banners identified by the CNIL

The CNIL’s investigation uncovered several common examples of dark patterns in cookie consent banners:

  • Unequal button presentation: “Accept” buttons are prominently displayed, while “Reject” options are harder to find, often hidden in plain text or styled less visibly.
  • Ambiguous wording: Misleading language, such as “I decline non-essential purposes,” creates confusion about the choices being made.
  • Repeated “Accept” options: Users are presented with multiple “Accept” buttons, while the “Reject” option appears only once.
  • Delayed rejection options: Users must click through multiple layers or sub-menus to reject cookies, making the process more cumbersome than accepting them.

The urgency of cookie consent compliance

Website publishers targeted by CNIL’s notice now face a one-month deadline to bring their cookie consent banners into compliance with CNIL cookie guidelines. Failure to act in due time could result in significant fines and reputational damage for the websites and companies in question. 

Given the CNIL’s history of imposing substantial penalties for cookie-related violations—Amazon fined €35M, Carrefour and Carrefour Bank fined €2,250,000 and €800,000— this warning should not be taken lightly.

CNIL cookie recommendations: Best practices for compliant cookie banners

To ensure compliance with CNIL cookie guidelines and avoid penalties, follow these best practices on your website:

  1. Equal visibility and accessibility: Make “Accept” and “Reject” buttons equally prominent in terms of color, size, and placement.
  2. Clear and transparent language: Use unambiguous wording that makes it easy for users to understand their options. Avoid phrases that obscure the option to reject cookies.
  3. Respect prior consent: Ensure that no cookies are pre-set or fired before the user has explicitly given consent.
  4. Simple rejection process: Users should be able to reject cookies with the same ease as accepting them, avoiding extra clicks or hidden menus.
  5. Comprehensive cookie audit: Regularly scan your website to identify all cookies and trackers in use (or implement a website consent solution that does this automatically for you).
  6. Detailed cookie categories: Clearly differentiate between essential and non-essential cookies, explaining their purposes in user-friendly terms.
