The aim of this study is to show how the institution of consolidated cases in Polish civil proceedings was shaped in the context of Polish criminal procedure and canon law. A comparative analysis de lege lata will help to determine the nature of the procedure aimed at issuing a sentence in cases that have been combined into one trial considering their subject matter, and thus answer the question whether there is a cumulative judgement in each of the procedures and how it is understood by the legislator in civil, criminal and canon law. The analysis is an important novelty in research on the institution of cumulative judgement because it enables a comparison of the institution not only within the framework of the state system of law, but also within the autonomous normative system created by canon law.
