There is a new open access edited volume on the Theory and Practice of the European Convention on Human Rights (Nomos, 2022). The book was edited by Stephanie Schiedermair, Alexander Schwarz and Dominik Steiger.
Here is a brief abstract.
"This edited book brings you a collection of current, critical issues regarding the theory and practice of the European Court of Human Rights. The book is divided into three parts: procedural concerns, principles and jurisprudence, and interaction with national legal systems. Each chapter was written by an expert, with each author coming from a distinct background. The authors all presented at the 2019 University of Leipzig’s & University of Dresden’s 1st International Summer School on the European Court of Human Rights, with only select presenters asked to contribute to this book. The book’s goal is to promote further research and discourse on the operation of the Court, a goal that will be continued in the second summer school in 2021. With contributions by Veronika Bilkova, Katharina Braun, Robert Frau, Hanaa Hakiki, Beti Hohler, Stefanie Lemke, Helga Molbaek-Steensig, Jacopo Roberti di Sarsina, Christiane Schmaltz, Barbara Sonczyk, Dominik Steiger, Edith Wagner and Alain Zysset."
