The adoption of feminicide in Brazilian legislation represents, for the feminist movement, the recognition of structural misogyny as the cause of these violent deaths of women, enunciative of gender oppression through the law. Furthermore, this naming would promote an essential change in the acting of the justice system in the judgment of these crimes, previously held on the basis of blaming the victim, on the moral judgment of her conduct and, consequently, on gender discrimination. Therefore, based on Catharine Mackinnon s Feminist Theory of the State and the parameters established by Law 13.104/15 and the National Guidelines on Feminicide, the work intends to investigate the incorporation of the gender perspective in feminicide trials in the Jury Courts of the City of Rio de Janeiro, which occurred after the entry into force of that law.
