Trade disputes raising a public morality defense have occupied and still hold to this day little spot within the World Trade Organization (WTO) Panels and Appellate Body. The defense, portrayed as an exception, has been submitted three times to the WTO “judges”: USA – Gambling, China – Publications and Audiovisual Products and EC – Seal Products. The doctrine has since made several assumptions which consist of many types of public morality measures. The latest dispute in the matter, opposing Canada and Norway to the European Union, helped shed new light on the defense by proposing a new morality test. The test is formulated in two steps: (1) determining citizens’ concerns and (2) whether the citizens’ concerns can be qualified as their public morality. The statement and the implementation of this test require some attention in order to measure the effects and understand the subtleties. It will mainly be demonstrated that the Panel, confirmed on this point by the Appellate body, seems to deviate from previous lessons regarding the public morality defense, requiring international justification of citizen concerns, which should also be supported by national evidence, to be recognized under public morality commercial exception.
