Transnational legal orders are an important feature of the contemporary global order, but they are challenging to study since they take many different forms, change over time, and consist of both formal and informal legal mechanisms. They lack the centralized political and legal systems of nation states, which are more capable of exerting formal control. Focusing on the processes, practices, and ideologies of transnational legal orders, as the chapters in this volume do, provides a valuable way to understand the way such orders develop and function. The chapters analyze the dynamics of creation, transformation, and demise of these forms of social organization through the in-depth analysis of individual TLOs engaged in controlling criminal behavior. Taken together, these chapters provide a rich understanding of this important and complex phenomenon.
