Facebook has taken the European Commission (EC) to court because the EC would search for more information than necessary during two ongoing investigations into Facebook. This would include "highly personal employee information," Facebook confirms after reporting by The Financial Times .

The EU competition authority is investigating how Facebook collects data from users and subsequently makes money from it. In addition, it is investigated whether the marketplace of Facebook, Marketplace, has an unfair advantage over competitors in placing advertisements on the platform.

Two insiders tell The Financial Times that Facebook provided the European Commission with 1.7 million pages of documents for these investigations, including internal emails. The EC would now have made a new request to receive all documents containing words such as "high demand", "free", "not good for us" and "closure".

Highly sensitive personal information

This request, according to Facebook, is too broad and would include documents containing private information of employees. These would include "highly sensitive personal information such as medical information, financial records and personal information about employees' family members," said Tim Lamb, general adviser to Facebook, in a statement. "We believe that such requests should be reviewed by EU courts."

EU officials said they followed the normal procedure and were not interested in employees' personal data. The European Commission says it will defend itself in court.

Facebook has asked the European court in Luxembourg to stop these data requests until judges have made a decision in the case.
