In 2017, the National Prosecution Bureau of Chile created the Special Unit for Human Rights, Gender-Based Violence, and Sex Crimes, becoming a milestone for criminal prosecution policies as the first time a state institution in Chile used the term 'gender-based violence' explicitly in its title. There was no law in the country that addressed and sanctioned this behaviour-recognising it as a social phenomenon-at the time of the Unit's creation. What does the creation of this new Unit mean for access to justice from a gender perspective? To answer this question, we have critically analysed the creation of this Unit as a case study from a feminist institutionalist standpoint. We found that this institutional change might bring a broadening in access to justice for women, girls and LGBTQI+ persons by implementing a gender perspective.
