This paper describes the journey of an empirical researcher during her doctoral studies. Narrated in first person, it describes the practical difficulties and theoretical discoveries built throughout the development of the research that culminated in the methodological choice of using the strategy of case study. Similarly, it inserts theoretical considerations about the methodological choices that presented themselves during the process, especially Robert Yin and Carlo Ginzburg. It explains how these works enabled the combination of several research strategies, along with case study. It describes in detail and reports the exploratory phase, the contact with other areas of research and with professionals in other fields. The text presents the results of research reported because it is not yet completed. It aims to contribute to the solidification of the debate about production of legal knowledge.
