Necessity and Proportionality in the WTO

The document argues that shifting from a strict 'necessity' test to a 'proportionality' test in WTO dispute settlements would transfer the power to balance trade interests against public policy goals from domestic democratic institutions to WTO panels and the Appellate Body. It specifically warns that proposed changes to the General Agreement on Trade in Services (GATS) could allow the WTO to outlaw domestic measures it deems 'out of balance' with their objectives, potentially undermining protections for the environment, human health, and consumers.

• The WTO's dispute settlement mechanism operates under a 'reversed consensus' rule, which means a panel or Appellate Body report is adopted unless every single Member objects, effectively removing the power to adjudicate domestic policy from national governments.
• A 'necessity' test traditionally implies that no alternative exists to achieve a goal, whereas a 'proportionality' test involves a weighing and balancing of conflicting policy objectives, a role traditionally reserved for domestic democratic institutions.
• Recent Appellate Body reports have begun interpreting necessity tests to include balancing elements characteristic of proportionality tests, and there are active negotiations to explicitly include proportionality tests in new WTO services disciplines.
• The introduction of proportionality testing could enable WTO tribunals to invalidate national measures if the trade-restrictive effects are judged to be excessive relative to the non-economic policy goals the measure intends to promote.
• The author argues that a flexible and deferential test is necessary to ensure WTO Members can effectively regulate for the protection of human health, consumers, and the environment, and that a proportionality test for technical regulations and licensing would be 'inappropriate'.
