This is a proposal to systematize the overruling in Brazilian Law. The current Civil Procedure Code has introduced a set of rules to regulate the formation and application of the binding precedent. Although it establishes the possibility of modifying the precedent, through appropriate and specific reasoning and compliance with the principles of legal certainty, justified reliance and isonomy (art. 927, paragraph 4) and mentions the overruling once only (art. 489, paragraph 1, VI), the Code does not specifically regulate this institute. On the other hand, the current interpretation of the courts on the rules of admissibility of exceptional appeals prevents the issue of overruling from being brought to higher courts, which carries a serious risk of stagnation of law. From the concept of overruling as extracted from the general theory and from its interpretation according to the constitutional norms of the rules inherent to the formation, application and modification of the precedents contained in our current procedural order, this work seeks to fill the legal gaps to identify the contours of overruling in Brazilian law, its material and procedural requirements, the transitional rules that must accompany it, with especial regard to the modulation of its effects, and the appropriate ways to promote it.
