This panel is based upon the premise that the use of indicators is an important form of power in global governance, which needs to be addressed from, perhaps even regulated by, international law. I agree with this assessment, but want to focus on a slightly different angle. My starting point is that many of the debates taking place these days on the structure of the international legal system can be usefully understood as problems derived from the interaction among regimes. Climate change, investment protection, humanitarian intervention--all these problems imply the interaction of different legal regimes (domestic, international, or transnational) whose outcomes and effectiveness depend not only on their own "internal" characteristics (that is, intra-regime), but also on the way in which they interact with each other--sometimes bolstering each other's effectiveness, sometimes annulling the very limited results they achieve.
In this context, indicators work as a hinge between regimes. In a world where each regime seems to derive its legitimacy from closed communities of experts, indicators work as a common language for communication among regimes. With their claim to technical neutrality, their well-organized and easily understood bits of information, and their trans-national, non-culturally based terminology, indicators are well-placed to help epistemic communities communicate with each other outside their own narrowly defined areas of expertise.
Indicators serve as the linguafranca of interaction among regimes. And if such interaction is potentially able to enhance or hinder international justice, then a more thoughtful look at indicators seems to be important, in order to understand the way in which international law not only confronts complexity, but also whether and how it contributes to a more just world.
Human rights law is an interesting example of how international law and indicators overlap. Here we have one of the most important areas of international legal regulation, and we have also one area where indicators have been developed in more detail. In this case, quantitative measurement is instrumental for experts and activists acting within the human rights regime to communicate with people and institutions acting outside that regime. For example, indicators play a role in the interaction between development experts and human rights lawyers, as is made clear by the World Bank's recent report on Human Rights Indicators and...
