Case register
Our case register includes information about the following types of Commission activity:
- Applications for:
- the authorisation or clearance of mergers
- authorisation of anti-competitive agreements
- clearance of competitor collaboration.
- Investigations of businesses or individuals under the laws that we enforce.
A case register entry is published when an application is accepted for assessment, or an investigation begins. The facts and the context of each case determine what detail we publish.
When deciding what to investigate we consider whether there is a reasonable basis to suspect a breach of the laws we enforce as well as our enforcement criteria and current priorities. The existence of an investigation does not mean that there has been a breach of the law, as only a court can make that determination.
