The Hamburg Higher Regional Court is reviewing a collective lawsuit targeting Meta, the parent company of Facebook, over alleged data protection breaches that affected millions of users. This legal action, initiated by the Federation of German Consumer Organisations (Verbraucherzentrale Bundesverband, vzbv), seeks to establish a legal precedent enabling affected individuals to claim compensation from Meta in Ireland more efficiently.

The lawsuit centers on a significant data breach that surfaced in April 2021, when information from over 530 million Facebook users across more than 100 countries was found circulating on the dark web. In Germany alone, approximately six million individuals are believed to have been impacted by the data leak. The breach exploited a vulnerability related to Facebook's user search functionality, allowing unauthorized parties to harvest user IDs, full names, countries, genders, and phone numbers between January 2018 and September 2019.

Background of the Data Breach

This data leak raised substantial concerns over Facebook's privacy safeguards. According to the consumer association, Meta failed to provide adequate protection for users' personal details and did not sufficiently inform affected parties about the breach. As a consequence, the Irish Data Protection Commission penalized Meta's Irish subsidiary with a fine of 265 million euros following an investigation into the incident.

Legal Implications and Previous Rulings

Thousands of individual lawsuits have already been filed against Meta in Germany. Initially, Meta prevailed in many lower court cases, largely due to disputes about the criteria required to claim damages. However, a decision by the Federal Court of Justice clarified that individuals only need to demonstrate they were victims of the data breach to be eligible for compensation.

Under Germany's model declaratory action law, introduced in November 2018, consumer organizations are empowered to represent groups of affected individuals in court. This legal framework, inspired by cases such as the Volkswagen emissions scandal, allows consumers to benefit from a collective judgment. Should the lawsuit succeed, those affected would be able to reference the court's decision to claim their damages, potentially without engaging in further individual litigation--especially if a settlement is reached.

Participation and Potential Compensation

The vzbv reported that by early October, more than 14,000 individuals had officially joined the collective lawsuit. Those interested in pursuing claims can still register through the Federal Justice Office's online portal, up to three weeks after the oral proceedings conclude. Additionally, the vzbv provides an online tool for users to determine if their personal data was part of the breach.

In terms of compensation, the consumer association is advocating for damages ranging from 100 to 600 euros per person, with higher amounts proposed for users whose data was more extensively compromised. The final compensation figures, however, will depend on the outcome of the court proceedings and any subsequent agreements or settlements.

Next Steps in the Legal Process

At this stage, the Hamburg Higher Regional Court is primarily addressing procedural issues, including the question of its jurisdiction over the matter. The timeline for the conclusion of the trial remains uncertain, and a decision is not expected immediately. The court has indicated that a separate date will be announced for delivering its verdict. Notably, the hearing is open to the public, emphasizing transparency in the judicial process.

Significance for Data Protection and Consumer Rights

This collective lawsuit is being closely monitored by privacy advocates and legal experts, as its outcome could set a significant precedent for handling mass data breaches and consumer protection claims in Germany and across Europe. The case underscores the growing importance of robust data protection measures and the potential liabilities faced by global technology companies when personal information is inadequately safeguarded.
