There is a pressing need to develop a research methodology for studying judicial opinions that goes beyond both dogmatic analyzes and the established positions developed within philosophy of law and legal theory (e.g. the hermeneutic and argumentative approaches). One possible way is to adopt or modify methodologies developed within empirically oriented social sciences. Most social science textbooks devoted to methodology of empirical research deal with case studies. So far, this research framework developed within the social sciences has not been applied directly to judicial opinions, though they have been used for some empirical legal research studies. Even et first sight, case study research would appear to have potential for use with judicial opinions. The aim of the paper is to answer the question, how and to what extent can case study methodology developed within the social sciences be fruitfully used to examine judicial opinions? The general answer is undoubtedly positive (case studies can bring new, non-trivial threads to the research methodology on judicial opinions), though with many serious and far-reaching reservations.
