PROTECTING FOREIGN INVESTMENT AND PUBLIC HEALTH THROUGH ARBITRAL BALANCING AND TREATY DESIGN

Abstract

AbstractThis article analyses the fraught relationship between host States’ obligations under investment agreements and their regulatory powers in the field of public health. First, tribunals addressing the merits of health measures have exercised considerable deference to States under existing treaties. Second, the recent generation of treaties spells out health considerations to encourage respondents or tribunals to adopt broad interpretations of the right to regulate, general exceptions, or article-specific carve-outs. Clauses modelled on GATT exceptions may prove difficult to invoke due to the ‘necessity’ threshold. Finally, the Kyoto Protocol may serve as a model of incentivising private investment in the public health sector.
