With effect from the 1st of July 2015 to the Polish Criminal Procedure Code was introduced the new Article 168a, which forms a legal basis to exclude from criminal proceedings the evidence obtained by means of criminal offense. However, on the basis of the amending act of 11th March 2016 the provision has been rewritten in such a way that admissibility of evidence obtained as a result of violation of the law is going to be a principle of criminal proceedings. From the axiological perspective such a change should be considered as a lawmaker’s permission to use evidence obtained in an illegal manner.
