The detailed Commentary “The revised European Social Charter” explores the boundaries of social rights at a European level through analysis of the Revised European Social Charter (RESC), the most comprehensive regional document on social rights. The Commentary considers the treaty as the counterpart of the European Convention on Human Rights, examining how it sets out fundamental rights in the social field. It focuses primarily on the rich jurisprudence developed by the Charter’s monitoring body, the European Committee of Social Rights (ECSR).
