At the end of the Interlaken Conference in February 2010, an Action Plan was made to improve the efficiency of the system for monitoring the execution of judgments and decisions of the European Court of Human Rights. Twelve years later, the time is ripe for an in-depth reflection of the various legal and political measures developed by the actors involved in the execution of the European Court of Human Right’s judgments. The aim of this volume is to examine the package of reform measures implemented by national authorities and analyse how these practices could be further developed and strengthened in the future in order to enable this unique international system of human rights protection to remain truly effective.
