ContextThis study explores the subjective and group repercussions of forced disappearance in the context of Latin American dictatorships in the 1970s. To comprehend the dynamics of such state violence, the study draws on a psychoanalytic approach of groups and institutions. The political repression during this era leads to a “social catastrophe” (Puget et al., 1989): following the collapse of democratic meta-social guarantors, the socio-political and institutional context becomes unrecognizable. In the aftermath of numerous crimes legitimized by the juntas, relatives of the disappeared have been fighting for decades against the impunity of the culprits, demanding justice be served. ObjectivesThe study aims to explore the various functions associated with testifying in trials for relatives of the disappeared. MethodAs part of a qualitative study, we interviewed twenty-nine relatives of disappeared people living in Switzerland. We analyzed the semi-structured interviews using thematic content analysis. We present some of the results of the cross-sectional analyses, illustrating them with a case study emblematic of the whole. ResultsFor relatives of the disappeared, testifying in a trial seems to be a royal road to actively participate in the restoration of democratic meta-social guarantors. In doing so, these relatives seek support from a collective and particularly from institutions, especially when these institutions regain their protective function against state violence. By testifying, they contribute to revitalizing narcissistic contracts and, more broadly, attempt to humanize not only the disappeared person but also their relatives and the perpetrators. InterpretationMemory work and the struggle for justice appear to be prevalent in the practices undertaken by close relatives of the disappeared, even fifty years later. Some of these relatives feel invested with a mission to memorialize and denounce political crimes in order to place them within history and to combat systematic erasure of crimes. This mission also allows them to symbolize, as far as possible, the catastrophe and their own history. This research is of course limited by the number of participants and the unique research interview. Further studies on the subjective and group repercussions of such state crimes and their transgenerational impact would be relevant to promote clinical listening to the relatives of the disappeared and their descendants.
