Abstract
The article outlines problems of the preparatory proceedings following the major amendment of the criminal procedure by the Act of 27 September 2013. It discusses the scope of matters covered by the individual forms of the proceedings (inquiry, investigation), the relations between the prosecutor and other authorities, inquiry and investigation time limits, pointing out in this aspect the differences of the penal fiscal procedure. Special attention has been given to the materially modified procedure ending the preparatory proceedings and the modified form of documenting the investigation process. The author focuses on presenting practical problems arising from the critical analysis of the amended regulations, which will be faced by those who will apply the new regulations after 1 July 2015. The publication takes into account the changes introduced by the Act of 20 February 2015.
