by Dr. Alkmini Fotiadou, Centre For European Constitutional Law. There is an almost universal consensus that the rule of law is desirable. Given this enthusiasm, it is remarkable how little is known about the factors conducive to it. A precondition for improving our knowledge of the rule of law is the ability to measure it. In a paper recently posted on the internet, Jerg Gutmann and Stefan Voigt from the University of Hamburg, set out to do just that. Based on very extensive data from a survey carried out in 99 countries, they propose a new indicator for the rule of law.
