There are several ways by means of which one could read the book by Dr. Christopher Soler entitled The Global Prosecution of Core Crimes under International Law. The book adopts a multi-layered approach in which every part is both autonomous and functional to the larger design. This outcome may correspond to the author’s own intellectual maturation while preparing his doctoral dissertation, but has the distinct advantage that the reader can benefit both from each and every chapter on its own, as well as from the entirety of the book as a whole for a unitary vision. To this extent, the book can serve as a valuable frame of reference for jurists, judges, legal practitioners, academics and public administrators who work in the dynamic fields of international human rights law and international criminal law, more so because the book has a noticeable substantive law dimension and a marked procedural law perspective.
