In this article I examine the provisions related to the prohibition of the evidence in the former and current Hungarian Criminal Procedure Code. The analysis of the legislation aims to find extentions, where the former investigative practices are modified by the current Code introduced on 1st July 2018, additionally whether interpretation problems can be occurred among practitioners. I use practical examples for the analysis that I have collected during my 20 year experience at criminal investigative authorities. Based on the analysis I found that the legislation is clearly and largely applicable, but in some aspects, addendums are needed.
