The Legitimate Regulatory Distinction Test: Incomplete and Inadequate for the Particular Purposes of the TBT Agreement

Prior to 2011, the Agreement on Technical Barriers to Trade had been somewhat neglected as a dispute-settlement mechanism, due in part to the lack of previous interpretation of the Agreement by WTO DSB Panels. In 2012, the Appellate Body adjudicated on three TBT disputes: US–Clove Cigarettes, US–Tuna II, and US–COOL, aiming to officially interpret and clarify Articles 2.1 and 2.2 of the Agreement by creating a distinct test for a measure's consistency with these Articles. This paper explores the relevant decisions of both the Panel and Appellate Body in the three disputes which led to the creation of the ‘legitimate regulatory distinction’ test. The substance behind this phrase, placed in context, is dissected along with the associated idea of ‘even-handedness’. The test attempts to simplify future interpretations regarding what will constitute unjustifiable discrimination, but at the cost of the necessary distinction between the GATT and the TBT Agreement being blurred. The result is a test which is incomplete and which fails to take account of the special circumstances surrounding the TBT Agreement.
