Joscha Müller, Reformhindernisse im internationalen Investitionsrecht Mohr Siebeck, 2020, ISBN 978-3-16-159090-0

The title of this book, ‘barriers to reform in international investment law’, runs short of the ambitious task undertaken by Joscha Müller as his doctoral thesis at the University of Marburg. For at the centre of the monograph stand not just the usual ‘barriers’ in the political sense but rather technical legal issues relating to the investment treaties themselves that may arise from the on-going reform process of international investment law. To this, Müller adds possible solutions, constructive suggestions, and perhaps the one or other bold—yet perfectly justified—claim.
