EU antitrust procedure

Investigation process

The European Commission (Commission) investigates evidence or allegations of anti-competitive behaviour contrary to Articles 101 or 102 TFEU by companies that has an impact in more than one EU country.

Investigations can generally start in one of four ways:

•
a party involved in any wrongdoing blowing the whistle
•
a complaint from a third party
•
the Commission receiving general market intelligence suggesting a breach of competition law, and
•
the Commission discovering alleged breaches of competition law during a sector inquiry

The European Commission (the Commission) has broad investigative powers to review suspected anti-competitive conduct. Among others, the Commission has the power to conduct unannounced inspections at the premises of any undertaking located in the EEA. See Practice Note: European Commission’s powers of inspection (dawn raids).

Investigations follow a set process and ensure companies under investigation have the opportunity to defend themselves. See Practice Note: Rights of defence in European Commission competition proceedings. Investigations can take several years to complete.

Commission adopts adequacy decision on Brazil’s data protection regime

The European Commission has adopted an implementing decision confirming that Brazil ensures an adequate level of protection for personal data transferred from the European Union under Regulation (EU) 2016/679 (General Data Protection Regulation (GDPR)). The decision concludes that Brazil’s legal framework, in particular the General Data Protection Law (LGPD), provides a level of protection for personal data that is essentially equivalent to that guaranteed within the EU, including enforceable rights for data subjects, effective oversight by an independent supervisory authority, and safeguards on access to data by public authorities. As a result, transfers of personal data from controllers and processors in the EU to controllers and processors in Brazil may take place without the need for additional authorisation under Chapter V of the GDPR. The decision is binding on Member States and will be subject to periodic review.

Commission publishes mid-term review of zero pollution action plan and PFAS cost study

The European Commission has published a mid-term review of the EU’s Zero Pollution Action Plan, alongside a study examining the societal costs of pollution caused by per- and polyfluoroalkyl substances (PFAS). The review evaluates progress since the action plan was launched in 2021 and concludes that most of the planned legislation is now in place. However, it finds that further action by Member States will be required for the EU to meet its pollution reduction targets by 2030. The accompanying study provides a minimum estimate of the costs associated with existing PFAS contamination and finds that, if current pollution levels persist until 2050 without further regulatory action, the societal cost could reach approximately €440bn. It concludes that reducing PFAS releases at the source is by far the most cost-effective approach, with measures implemented by 2040 expected to save around €110bn, compared with treating polluted water without addressing emissions at their source, which would cost more than €1trn.
