Wrongful convictions and miscarriages of justice, their reasons and effects, only rarely become the subject of academic debate in Poland. This article aims at filling this gap and providing a discussion on the current challenges of mechanisms available in Polish law focused on the verification of final judgments based on innocence claims. While there are two procedures designed to move such judgment: cassation and the reopening of criminal proceedings, only the latter aims at the verification of new facts and evidence, and this work remains focused exactly on that issue. The article begins with a case study of the famous Komenda case, which resulted in a successful innocence claim, serving as a good, though rare, example of reopening a case and acquitting the convict immediately and allows for discussing the reasons that commonly stand behind wrongful convictions in Poland. Furthermore, the article examines the innocence claim grounds as regulated in the Polish criminal procedure and their interpretation under the current case law. It also presents the procedure concerning the revision of the case. The work additionally provides the analysis of the use of innocence claim in practice, feeding on the statistical data and explaining tendencies in application for revision of a case. It also presents the efforts of the Polish Ombudsman and NGOs to raise public awareness in that field. The final conclusions address the main challenges that the Polish system faces concerning innocence claims and indicates the direction in which the system should go.
