This article aims to present, through comparative, historical and statistical method the importance of the judicial precedent for the research and study of Cooperative Law from the approach between the common law andthe Brazilian legal system, traditionally tied to the civil law system. Although the Codes arethe main sourcesof Brazilian Law,judicial precedent conquered relevant space in the Brazilian legal system due to the culture of valuing standardization of jurisprudential understandingtied to the technological modernization of the Brazilian legal structure. Based on that, the OCB System, as an entity that represents Brazilian cooperatives, has refined the research work and study of Cooperative Law through monitoring and disclosure of judicial decisions to strengthen the cooperative movement in Brazil.
