The conflict between free trade and public health measures : the role of science

Abstract

The needs of the free trade regime and governments' legitimate regulatory aims in the area of public health protection conflict. Government health measures create barriers to free trade and are thus disciplined by the trade regime. This conflict is addressed in the rules of the World Trade Organization, in the Agreement on the Application of Sanitary and Phytosanitary Measures. This Agreement uses science to mediate the conflict. The reason for the reliance on science is the view that it provides a neutral, universally-valid discipline and that thus the results of testing health measures for scientific validity would be acceptable to both parties in a dispute. This uncritical approach towards science is called into question. An analysis of the relevant science-based disciplines of the SPS Agreement and their interpretation in WTO dispute settlement shows the flaws in this system. A re-evaluation of the WTO rules governing health regulation is called for.
