s.V Modalities, Ch.17 The Two Cultures of International Criminal Law
This chapter looks more globally at the methodologies used by international criminal justice, particularly its tendency towards expansionism: including more actors, more situations, and more offences under its umbrella. It does more than simply tell the story of this expansion; this chapter also systematizes it in an important way. The chapter argues that international criminal justice’s expansionism has taken two important forms. The first wave involved a sources-based expansionism, characterized by the field’s desire to expand its influence by increasing the number of legal sources—treaty, custom, general principles—that could be sources of international criminal law. But when that process was largely complete, the passage of the Rome Statute of the International Criminal Court heralded a new, hermeneutic form of expansionism—this one based on interpretation rather than on adding new sources of law. While the hermeneutic expansion is less overt and less recognized than the first wave, its consequences are still dramatic.
