Abstract
Part I of the article outlined the scope of changes introduced by the Amending Act of 2017 and discusses intertemporal issues connected with the amendment. The detailed discussion to be continued in the subsequent three parts of the study will present the changed scope of application of the Code of Administrative Procedure (supplemented primarily with the issues of administrative monetary penalties and European administrative cooperation), as well as new solutions regulating settlement of legal and factual doubts in favour of a party.
