This work analyses an ensemble of collective initial hearings, known as Audiencias de Control de Detención Colectivas (ACDC), understood as the initial proceeding where the detained individual is taken to a judge within twenty-four hours of the arrest in order to verify the legality of the arrest, the individuals’ awareness of their rights, that the established laws for the rights and legal guarantees are respected and leave a record of the proceeding. This work, carried out from a discourse perspective, aims to understand how ACDCs function and how this affects individual’s access to justice. To examine this, we used the methodology proposed in Discourse Analysis, including elements from the French school of Discourse Analysis such as the theory of the communication contract and the discursive ethos; as well as concepts from the English and Spanish speaking schools of Discourse Analysis. In addition, we included concepts from Sociology of Law and took into consideration the historical context of the Chilean Criminal Law Reform. This research was conducted using a corpus composed of eleven ACDC that took place in the Magistrate Court of Concepción, recorded between August of 2018 and March of 2020. The results show the importance of the discourse dimension regarding turn distribution, types of discourse organization and forms of address that impact an individual’s way of accessing justice.Este trabajo analiza un conjunto de audiencias de control de detención colectivas desde una perspectiva discursiva, con el propósito de describir su funcionamiento y de qué manera este incide en el acceso a la justicia. La metodología empleada corresponde a la del Análisis del Discurso, que contempla elementos provenientes del mundo francés (teoría de contrato de comunicación y ethos discursivo), anglosajón e hispano (teoría de la cortesía verbal). Además, este trabajo incorpora elementos de la Sociología del Derecho y el contexto histórico de la Reforma Procesal Penal en Chile. El corpus está compuesto de once audiencias de control de detención colectivas registradas en el Juzgado de Garantía de Concepción, entre agosto de 2018 y marzo de 2020. Los resultados de los análisis ponen de relieve la importancia de la dimensión discursiva en el acceso a la justicia, específicamente, la incidencia que tienen elementos como la distribución de la palabra en este fenómeno.
