Necessity Testing
Part III comprises two chapters, Chapter Five and Chapter Six. These chapters together investigate the decisions of WTO panels and the Appellate Body in environmental and health cases. The chapters examine the major contribution made through WTO dispute settlement to the emerging global regulatory standard of regulatory coherence. Specifically, Chapter Five analyses the elaboration of the ‘necessity’ formula in the GATT and the GATS general exceptions’ subparagraphs, as well as under the TBT and SPS Agreements. The WTO adjudicatory process appears to have been protecting the traditional procedural justification of international law’s relative authority claim by enabling respect for domestic decision-making through democratic processes. Members’ entitlement to choose their level of protection against a risk is still at present fully recognised and there is vital scope for recognition of the importance to WTO Members of long-term non-economic interests requiring a multifaceted policy response.
