Abstract
One of the important areas of procuratorial supervision over preliminary investigation is supervision of the legality of measures of restraint. The procurator must be particularly attentive with regard to the legality of application of a measure of restraint such as confinement under guard, as it touches the interests of the citizen most significantly. Confinement under guard (as well as other measures of restraint) is usually applied to an accused (Article 89, RSFSR Code of Criminal Procedure), and only as an exception to a suspect (Article 90, ibid.).
