The use of pre-trial detention in Chile is widely debated. Chilean legal scholars, for the most part, have advocated a restrictive interpretation. Despite this, empirical research studies on the use of pre-trial detention in Chile has revealed an increase in its use during the last decade and the development of standardized working strategies in judicial decision-making in this institution. To date, we lack in-depth analysis of the practice of this standardization and its specific relationship to pre-trial detention decisions. Based on non-participant observation of hearings and interviews with judges, prosecutors and defense attorneys in courts in the Araucanía and Bio-Bio regions, this article presents an empirical analysis of the application of pre-trial detention in Chile. In particular, how does the standardization of judicial practices influence the way decisions on pre-trial detention are made in Chile? The research study focused on the bureaucratic management of time from a socio-legal perspective. It finds that, in the face of time pressures, courts have adopted specific strategies to organize hearings, generating different types of hearings, each with its own speed and logic of standardization. The article emphasizes the need for a detailed and empirical exploration of the processes of bureaucratization within the judicial system and the tangible impacts these processes have on the fairness of access to justice.
