The article addresses the issue of Brexit in the context of economic analysis of law using a qualitative method, namely the textual analysis of selected papers devoted to both the process of secession of Great Britain from the European Union and the aforementioned research school. The hypothesis of this work is as follows: economic analysis of law reveals limited applicability to the exegesis of the Community disintegration mechanisms, including Brexit, which is one of the symptoms of these processes. According to the author, it reveals certain shortcomings in the research procedures regarding the phenomenon of EU decomposition, although, on the other hand, some of its components still remain valid.
