On September 9, 2018 it was announced that the Public Prosecutor's Office would keep the accusation of rebellion for the separatist leaders that fled or are imprisoned. In May 2019 Segarra issued a working circular with guidelines regarding the interpretation of article 150 of the Spanish Criminal Code concerning hate crime which advised prosecutors that aggression against people holding a belief in Nazi ideology or incitement to hatred against Nazis could be prosecuted under this law due to its ambiguity. The circular was strongly criticised by a number of lawyers and legal associations, including Judges for Democracy, who argued that the guidance could enable prosecutions of concentration camp survivors, and that it violated judgements made by the Constitutional Court. Segarra was ceased from the office on 15 January 2020 as Dolores Delgado was nominated as her successor.
