      the practice of incarcerating accused individuals before trial on the assumption that their release would not be in the best interest of society—specifically, that they would be likely to commit additional crimes if they were released. Preventive detention is also used when the release of the accused is felt to be detrimental to the state's ability to carry out its investigation. In some countries the practice has been attacked as a denial of certain fundamental rights of the accused.

      The procedure has been used primarily in civil-law countries, in some of which, particularly France and Belgium, the rights of individuals detained before trial were more carefully protected. In 1970 in France the practice was placed exclusively in the hands of the courts. In Belgium a review of every individual detained in this manner must be held monthly to determine if his release would still constitute a threat to society.

      Preventive detention is used to a considerable extent in countries ruled by dictators. It was also found in the Soviet Union (Union of Soviet Socialist Republics), particularly in cases in which the accused individuals were perceived as political or security threats to the government. In such countries, where there was often little concern for the protection of individual rights, preventive detention was left almost exclusively in the hands of police and prosecuting authorities. Where there is greater concern for individual rights, the courts have been given control; but critics maintain that the practice in any form does not lend itself to vigorous and continuous protection of individual rights.

      Court-supervised preventive detention was adopted in 1970 in the United States by the federal government for the District of Columbia over much protest that the measure constituted imprisonment without due process and amounted to the curtailment of rights only because of behaviour that might occur. The procedure has been used sparingly, and its constitutionality has not been fully adjudicated in the courts. See also accused, rights of; due process.
