The introduction lays out the book’s aim as providing an investigation into the emancipation of the ECHR from an international agreement with a relatively weak enforcement structure into a sophisticated legal system. The introduction argues that researching supranationality under the Convention offers a fresh descriptive-analytical perspective on the ECHR as well as a deconstruction of the ECtHR’s authority. Carrying forward legal-institutional scholarship and studies on the domestification of the ECHR, it also introduces the idea of reviving the notion of Convention community. Lastly, the introduction provides an overview of the book’s structure and presents the line of argument and the methodology adopted in the different chapters.
