Remarks by Tania Voon
The WTO general exceptions are crucial provisions that recognize that in some circumstances non-trade objectives will trump trade liberalization. That recognition flows from the fact that trade liberalization per se is not the purpose of the WTO; rather, trade liberalization is a means to achieve other objectives as specified in the preamble to the Marrakesh Agreement Establishing the World Trade Organization, such as raising standards of living and ensuring full employment. The predominant view is that the general exceptions are extremely difficult to satisfy. Indeed, I am aware of only three instances in which a respondent has successfully invoked GATT Article XX; of these, two are compliance proceedings, and one of those is under appeal. However, challenged measures typically fail to satisfy the requirements of the Article XX chapeau because they are discriminatory, and removing that discrimination provides a means of benefiting from the exception.
