Abstract
Implementation of directives which in many spots fail to regulate issues exhaustively or only just introduce certain institutions and ideas makes the national legislator, on one hand, responsible for creating regulations which would follow the aims outlined in that legal act, and on the other makes the legislator free to choose whatever measures are appropriate for local conditions.
Such acts are new public procurement directives, in particular owing to the fact that their provisions provide the national legislator with additional instruments to impact a number of elements of the situation with respect to the economic, special or environmental aspect.
Apart from the procedural elements affecting effectiveness of the proceedings, the directives concern the issues which may be defined as literally systemic (in-house orders) or which may (significantly) affect execution of some public tasks (opening the market to contractors and goods from outside of the EU or states with which the EU has singed relevant trade agreements).
