Abstract

In competition law investigations, the right of defence is, among others, guaranteed by the exercise of the Legal Professional Privilege. The right of the client under investigation to maintain the secrecy of communications with his lawyer before the EU Commission is ensured only by the manner in which the legal instruments provided correspond to effective protection, which have to be harmonised with ECHR jurisprudence on the topic. The rules on protection are the result of a delicate balancing act between the rights of the party and the interest of the investigation. The Commission’s Guidance on best practices in such investigations, as a soft-law instrument, raises some interesting challenges with respect to the power of the investigative party when conducting dawn raids in relation to Legal Professional Privilege. The present study analyses the legal regime of attorney-client privilege in EU competition investigations and the manner of handling documents containing such information in the context of an investigation and their compatibility with the principles laid down in Article 6 and Article 8 ECHR.
