Any EU country can take legal action against companies like Facebook over cross-border violations of data privacy rules, not just the main regulator in charge of the company, a top court adviser said Wednesday.
The advice from the European Court of Justice's Advocate General Michal Bobek also paves the way for an onslaught of fresh data privacy cases across the EU, experts said.
The opinion, which is often followed by the court, comes ahead of a formal decision by the ECJ's judges expected later this year.
Facebook argues that the Belgian watchdog, which launched the case in 2015, no longer has jurisdiction after the EU's strict General Data Protection Regulation took effect in 2018. The company says that under GDPR, only one national data protection authority has the power to handle legal cases involving cross-border data complaints - a system known as "one-stop shop." In Facebook's case, it's the Data Protection Commission in Ireland, where the company's European headquarters is based.
"The lead data protection authority cannot be deemed as the sole enforcer of the GDPR in cross-border situations, and must, in compliance with the relevant rules and time limits provided for by the GDPR, closely cooperate with the other data protection authorities concerned," the opinion said.
Facebook said it was "pleased that the Advocate General has reaffirmed the value and principles of the one-stop-shop mechanism, which was introduced to ensure the efficient and consistent application of GDPR. We await the Court's final verdict."
Privacy advocates and experts said the advice could change how data privacy cases are handled, by taking the pressure off a single watchdog.
Johnny Ryan, a senior fellow at the Irish Council for Civil Liberties, said Bobek is signalling that Ireland's privacy watchdog "can no longer use its status as lead authority for Google, Facebook, etc. to hold up enforcement of the GDPR across the EU."
The Irish watchdog has faced criticism for not dealing quickly enough with a rising pile of cross-border data privacy cases involving big tech companies since GDPR took effect. It issued its first such penalty to Twitter last month, fining it for a security breach, but still has about two dozen more to go.
Businesses could also face a bigger compliance burden responding to more privacy cases in multiple EU markets, because it would be easier for people to file complaints to their local privacy watchdog, said Cillian Kieran, CEO of privacy compliance startup Ethyca.
