The Hungarian Competition Authority (HCA) has used dawn raids for a long time, primarily in cases of suspected cartels. In a dawn raid, the HCA’s investigators are authorised – without prior notification on their arrival – to review and seize all paper-based and electronic documents and communications as well as communication devices (laptops, telephones, etc.) of a company suspected of an infringement. The investigators may enter all of the buildings and other premises used by the company and interview all of its employees.
