Abstract
Recently, we have experienced the need to postpone the applicability of certain European regulations within the financial sector due to the late adoption of related acts on lower level by the European Commission or European supervisory authorities (MiFID II, PRIIPs, IDD). It shows gradually that Lamfalussy structure may not bring the needed improvement of implementation of financial services regulations.
Moreover, the entire process of postponing IDD uncovered other unsolved aspects that raise important issues, such as adopting various forms of European level2 acts in conjunction with the late national transposition of level1 act.
