This Study is dedicated to the impact analysis of the anticorruption proofing of the legal and normative acts during 6 years: 2010 – 2015. The Study analyses the phenomenon of promoting individual/private/corporate interests through draft legal and normative acts to the detriment of public interest. It also highlights how the NAC corruption proofing reports can contribute to stopping promotion of the interests causing prejudice to public interest. The Study presents a first attempt of evaluating the costs of prejudice caused by the legal and normative acts promoting private interests.  It analyses two main categories of acts: normative acts (Government Decisions) and legal acts (laws initiated by the Government and Members of Parliament).
