FACTSHEET Detention Monitoring Tool  Second edition Pre-trial detention Addressing risk factors to prevent torture and ill-treatment ‘Long periods of pre-trial custody contribute to overcrowding in prisons, exacerbating the existing problems as regards conditions and relations between the detainees and staff; they also add to the burden on the courts. From the standpoint of preventing ill-treatment, this raises serious concerns for a system already showing signs of stress.’ (UN Subcommittee on Prevention of Torture)1 1. Definition and context 2. What are the main standards? Remand prisoners are detained during criminal investigations and pending trial. Pre-trial detention is not a sanction, but a measure to safeguard a criminal procedure. Because of its severe and often irreversible negative effects, international law requires that pre-trial detention should be the exception rather than the rule. At any one time, an estimated 3.2 million people are behind bars awaiting trial, accounting for 30 per cent of the total prison population worldwide. In some countries, pre-trial detainees reportedly constitute the majority of the prison population, and in some settings even over 90 per cent of detainees.2 They are legally presumed innocent until proven guilty but may be held in conditions that are worse than those for convicted prisoners and sometimes for years on end. Pre-trial detention undermines the chance of a fair trial and the presumption of innocence. It increases the risk of a confession or statement being coerced by torture or ill-treatment and ‘lessens a suspect’s possibilities of defence, particularly when the person is poor and cannot rely on a defence counsel or support to obtain evidence in his favour’.3 Alongside the general risk of violence from guards and fellow prisoners, high rates of pre-trial detention also contribute to widespread prison overcrowding, exacerbating poor prison conditions and heightening the risk of torture and ill-treatment.4 Pre-trial detention is only legitimate where there is a reasonable suspicion of the person having committed the offence, and where detention is necessary and proportionate to prevent them from absconding, committing another offence, or interfering with the course of justice during pending procedures. This means that pre-trial detention is not legitimate where these objectives can be achieved through other, less intrusive measures. Alternative measures include bail, seizure of travel documents, the condition to appear before the court as and when required and/or not to interfere with witnesses, periodic reporting to police or other authorities, electronic monitoring, or curfews. Both the UN Standard Minimum Rules for Non-custodial Measures (the ‘Tokyo Rules’) and the UN Rules for the Treatment of Women Prisoners and Non-Custodial Measures for Women Offenders (the ‘Bangkok Rules’) encourage criminal justice systems to provide a wide range of non-custodial measures to avoid the unnecessary use of imprisonment. However, the absence of alternatives and shortcomings in their implementation have been reported by international5 and regional6 1.
