    ECJ’s view on attorney-client privilege: When will professional secrecy apply? What is the view from Turkey?

    The attorney-client privilege has always been considered within the scope of the right to defence by the ECJ.

It is a matter of great curiosity whether (and how) the ECJ’s decision will affect local competition authorities, including the Turkish Competition Authority.
