Lost in Translation or Full Steam Ahead: The Transposition of EU Transport Directives across Member States

Abstract: This study supplements extant literature on implementation in the European Union (EU). The quantitative analysis, which covers the EU transport acquis, reveals five main findings. First, the EU has a transposition deficit in this area, with almost 70% of all national legal instruments causing problems. Second, transposition delay is multifaceted. The results provide strong support for the assertion that distinguishing between the outcomes of the transposition process (on time, short delay or long delay) is a useful method of investigation. Third, factors specific to European directives (level of discretion and transposition deadline) and domestic-level factors (national transposition package and number of veto players) have different effects on the length of delay. Furthermore, the timing of general elections in member states as well as policy (sub)sector-related accidents influence the timeliness of national transposition processes.
