This publication addresses human rights monitoring of the justice system through the creation of a methodology. This tool is intended to reflect a comprehensive overview of the principles, techniques and approaches involved in legal systems monitoring, principles which have been primarily garnered from previous experience and lessons learned from United Nations, Organization for Security and Co-operation in Europe and non-governmental organization legal systems monitoring programmes. The objective of this tool is to provide a framework for developing a monitoring programme to analyse institutions and the justice system as a whole from which good practices can be reinforced and bad practices or deficiencies addressed.
