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.
