In the Fashion ID case (C-40/17) , the Court of Justice of the European Union (CJEU) found that the operator of a website that features a plug-in (such as a Facebook ‘Like’ button), can be considered a joint controller with the plug-in provider, in respect of the collection and transmission to that plug-in provider of the personal data of visitors to its website. However the website operator will not be a joint controller or liable for any subsequent processing of the personal data by the plug-in provider.
The CJEU also held that the website operator is responsible for obtaining consent from website visitors for the collection and transmission of their personal data and providing notice to visitors about the use and disclosure of their personal data.
Although the case was decided under the the Data Protection Directive 95/46/EC (the Directive), it will continue to be relevant under the GDPR, since the relevant definitions and obligations continue to apply under the new regime. The decision will have an impact not only on website operators that embed social plug-ins, but to any website operator that uses cookies to collect and transmit personal data of their visitors to third parties, such as AdTech providers.Continue Reading A website operator embedding a Facebook ‘Like’ button is a joint controller with Facebook
