Derogations under Article XX of the GATT are permitted as long as the resulting measures are not unjustified or arbitrary. This implies that the country has no other means of pursuing objectives that would avoid restrictive trade practices. In this context, the general principles of international law and other international conventions ratified by members may also be taken into account when interpreting the extension of a waiver (US – Shrimp, WTAB/R, 1998, para. 35). See also the Vienna Convention on Treaty Law Article 31.3.c). Unlike the ITO charter, the GATT did not need congressional approval. Technically, the GATT was a 1934 agreement, in accordance with the provisions of the U.S. Reciprocal Trade Act. The Uruguay Round of multilateral trade negotiations of the General Agreement on Tariffs and Trade (GATT) ended in 1994, after 7.5 years of negotiations, with the signing of the final deed on 15 April 1994 in Marrakech, Morocco. This issue, known as the « GATT of 1994, » led to the creation of the World Trade Organization (WTO) on 1 January 1995.
Among the agreements included in the WTO Treaty is the Agreement on the Application of Health and Plant Health Measures (SPS Agreement), which sets out the basic rules for the protection of human, animal and plant health during international trade (WTO, 1995). In addition to facilitating applied tariff reductions, GATT`s contribution to trade liberalization includes « the commitment of extended-term tariff reductions (which became more sustainable in 1955), the definition of universality of non-discrimination through the treatment of the most favoured nation (MFN) and the status of domestic treatment, ensuring greater transparency in trade policies and creating a forum for negotiations and the peaceful settlement of bilateral disputes. All of these have helped to streamline trade policy and reduce trade barriers and political uncertainty.  This statement served as the basis for the so-called « Malthouse Compromise » between conservative parties on how to replace the withdrawal agreement.  However, this plan was rejected by Parliament.  The assertion that Article 24 could be used was also adopted by Boris Johnson during his 2019 campaign as leader of the Conservative Party. The summit almost resulted in a third organization. This should be the very ambitious International Trade Organization (ITO). The 50 countries that started negotiations wanted an agency within the United Nations to create rules, not only for trade, but also for jobs, agreements on raw materials, trade practices, foreign direct investment and services.
