Abstract
The research analyses the extent of the duty to give reasons reasons and how it is specialised in the various categories of acts and measures, as well as in the different forms of administrative decisions that do not result in any type of act or measure, starting from the administrative proceeding law, and also including special legislation and case law. In particular, we have sought to highlight how behind the apparent general nature and uniformity of the giving reasons requirement of administrative acts, governed by Article 3 of the administrative proceeding law, the legislature itself and case law have created multiple, special heterogeneous rules based on which a plurality of obligations to state reasons can be identified.
