The European Prison Rules is under revision. The purpose is to create a more comprehensive and logical structure and revise some of the rules, primarily the ones on Solitary confinement, Women, Complaints, Inspections and monitoring, Foreign nationals, Adequate staffing level, Use of restraints and Records and file management. Some changes can be expected in the Preamble in order to align them to the most recent judgments of the European Court of the Human Rights and the UN Standard Minimum Rules for the Treatment of Prisoners (The Nelson Mandela Rules).
