The GATT security exceptions were practically in hibernation until recently. The recent WTO disputes panel activity concerning such exceptions is characterized by a standard of review that places the accent on ‘when’ action should be taken and not so much on ‘what’ action should be taken. We see two problems with this construction. First, the ‘when’ might be a function of privileged information that those possessing it might be unwilling to divulge in a transparent manner. Second, national security is an amorphous concept, and unless we disaggregate it, it is impossible to pronounce the appropriateness of measures adopted to pursue the underlying objective. In turn, the absence of disaggregation could lead to false positives and negatives, as the same action could be pursuing essential security or providing protection to domestic players.

This paper reviews the World Trade Organization (WTO) Panel Report Russia – Measures Concerning Traffic in Transit of April 2019. It constitutes the first attempt to disentangle the legal and political aspects related to the invoked essential security interests from the economic considerations underlying the measures imposed on the transit through Russia of goods exported from Ukraine to the Republic of Kazakhstan and Kyrgyzstan. One the one hand, the panel's interpretation of Article XXI of the GATT denies Members unilateral determination over security exceptions. It further enables a pathway for future WTO panels to review possible abuses of security exceptions – a growing concern due to the rising complexity of transnational economic relations. On the other hand, our economic analysis suggests a stricter assessment of Russia's transit restrictions was necessary. In particular, it argues that the panel adopted a circular assessment when considering the plausibility of whether Russia implemented its measures for the protection of its essential security interests at a time of emergency in international relations. Ultimately, although the panel's focus on finding a diplomatic and legal path forward failed economic scrutiny a legal assessment argues that the panel's findings fit the legal design of Article XXI:b of the GATT.
