Rational Relationships
Chapter Six continues Chapter Five’s examination of the regulatory coherence standard in WTO dispute settlement, this time focusing on ‘rational relationship’ testing under the non-discrimination provisions in the chapeau to the GATT and GATS general exceptions, as well as under the TBT and SPS Agreements. WTO non-discrimination jurisprudence looks for a rational relationship between a regulatory measure’s otherwise discriminatory aspects and the measure’s policy objectives. Rational relationship tests, like necessity tests, embody the emerging global regulatory standard of regulatory coherence, calling for a certain relationship between trade measures and their objectives. Like necessity testing, rational relationship testing lends itself to application in a way that accommodates decision-making at the domestic level on matters requiring important value judgements.
