Rosalind Dixon (University of New South Wales (UNSW) - Faculty of Law) has posted Proportionality & Comparative Constitutional Law Versus Studies ((2018)12(2) Law & Ethics of Human Rights 203) on SSRN. Here is the abstract:
The doctrine of proportionality has received sustained attention from comparative constitutional scholars. Yet it is an area where courts, and scholars, have made limited use of empirical or inter-disciplinary approaches to constitutional comparison. The article calls for a change in this practice as part of a broader call for greater dialogue between scholars and practitioners of conceptual and more empirical forms of constitutional comparison.
Highly recommended.
