Abstract
The present study seeks to analyze ADPF 779 MC, from a report by Minister Dias Toffoli, and its importance, because of the legitimate defense of honor argument, going back to the Doca Street case, but without exhausting the theme. Dissatisfaction with the thesis of legitimate defense of honor vs. the dignity of Brazilian women is detailed through a bibliographic and methodological study, by raising a famous case from the 70s, called Doca Street. Finally, it was verified that there is no room for the argument of the legitimate defense of honor, because of the space of death of victims of femicide in the country and that such a measurement is unconstitutional and offensive to female dignity.
