Global Comparative Law?

The Cambridge Handbook of Comparative Law, edited by Matthias Siems and Po Jen Yap, continues recent calls to expand the field of comparative law. By including authors drawn from all parts of the world, it presents 'new perspectives' on the field. This wide geographic remit proves successful as a way of moving beyond traditional 'families' and doctrinal topics. The contributors raise new themes for comparison, many related to public law and processes of change. But this, in turn, raises questions about the purposes of expanding the field. The volume largely concerns the laws and legal issues of modern states, and the authors do not venture far into history. Nor do they consider the alternatives offered by religious and traditional legal systems or forms of non-state ordering. I suggest that these subjects could productively expand the field even further, raising more theoretical questions about what law is and does.
