Hadjigeorgiou on Beyond Formalism: Reviving the Legacy of Sir Henry Maine for CIL

Andreas Hadjigeorgiou, University of Groningen; University of Antwerp; Frederick University Cyprus, is publishing Beyond Formalism: Reviving the Legacy of Sir Henry Maine for CIL: The Theory, Practice and Interpretation of Customary International Law in The Theory and Philosophy of Customary International Law and Its Interpretation (P. Merkouris, J. Kammerhofer, and N. Arajavi, eds., Cambridge University Press, 2021, Forthcoming). Here is the abstract.

Not all ontological concerns which surround the concept of (customary) international law (CIL) have disappeared, rather they have shifted. Whereas the existence of a genuine international legal system is taken as a ‘given’, questions still remain about its genesis and the position of CIL within it. Some for example, still question whether we can truly speak of customary international law, while others recast the concept of CIL through a formalist perspective. Accordingly, formalism, in its moderate form, treats formal sources, documents and/or proclamations as ‘better’ tools for both a) the preservation of existing rules of CIL, and b) the ‘creation’ of new legal rules. At its more extreme, formalism purports the view that c) IL (or even CIL) finds its genesis only in formal sources, documents, or proclamations. While some formalisation is undeniably helpful and even necessary, we should be more critical of this formalist paradigm. In this way, the chapter seeks to respond to these positions through a revival of the legacy of Sir Henry Maine and the evolutionary conception of law that he laid out the first foundation for. By operationalizing this conceptualization, a new vision spawns for CIL: a vision beyond mere formalism.
