In the theory, legislation and practice of regulation and conduct of administrative procedures, trends towards the concept of good administration can be detected at both supra- and national levels. Based on normative and comparative-legal analyses of Slovene (1999), Croatian (2009) and the EP Resolution (2013) administrative procedure acts (APAs), the article identifies user-oriented institutions that pursue the principles of good administration. Furthermore, it examines acceleration and braking mechanisms that influence the duration of procedures (e.g. setting and shortening time limits, positive fiction, preclusions, and enforcement of procedural errors, broader participation of affected parties, legal protection). Timely and efficient decision-making viewed as a human right with balanced protection of public and private legal interests is in fact crucial for achieving good administration. Hence, in conclusion, the authors propose selected changes de lege ferenda for the reregulation of APAs in Slovenia and beyond, in support of less excessive length of procedures.

The case law of the Court of Justice on revoking a national final administrative decision or judgement which is not compliant with EU law can illustrate the existing tension between the principle of primacy on the one hand, and the principle of national procedural autonomy on the other. Although the Court’s choice for one of the two principles as a starting point for solving a collision between EU law and national law may seem arbitrary at first glance, a system may be possible to a certain extent. This study discusses this system, hoping to provide a possible model of explanation which may be applicable to future case law.
