A problem I find common to many introductory texts in any of the various legal spheres is that they so often become carried away and forget their purpose; to provide a competent and relatively succinct summary of the relevant area of law while also setting the reader on the right path to further research if they desire to engage in it.
This newest edition brings up to date a work which had already succeeded in fulfilling each of those goals, being less a dusty tome and instead more an easily accessible guide, while being unabashed about leading the reader to materials which disagreed with the narrative put forward by the authors as often as not.
In particular, and as one might expect given its title, the work does not shy away from examining the procedural quirks of the newly formed ICC in spite of the limitations imposed by the paucity of jurisprudence, avoiding the understandable desire to focus solely upon the substantive and theoretical meat of the area which has seized other, otherwise excellent, works.
Just as Shaw has done with his own excellent work in the Public International sphere, Cryer and his co-authors do an excellent job providing a text which serves as both an engaging précis to the relatively nascent area of International Criminal Law and a fruitful gateway for further research.
