The assertion that Article 24 could be used in this way has been criticized as unrealistic by Mark Carney, Liam Fox and others, as point 5c of the contract requires an agreement between the parties so that Article 5b can be useful, since there would be no agreement in the case of a non-agreement scenario. In addition, critics of the GATT 24 approach point out that services would not fall under such regulation.  While GATT was a set of rules agreed upon by nations, the WTO is an intergovernmental organization, with its own headquarters and staff, whose scope covers both goods traded and trade in the services sector and intellectual property rights. Although used for multilateral agreements, multilateral agreements have led to selective exchanges and fragmentation among members in several rounds of negotiations (particularly the Tokyo Round). WTO agreements are generally a multilateral mechanism for the settlement of GATT agreements.  The Uruguayan 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). One of GATT`s most important achievements has been indiscriminate trade. Any GATT signatory should be treated like any other, known to be the nation`s most privileged principle and entered into the WTO. The practical result was that, once a country had negotiated a tariff reduction with some other countries (usually its major trading partners), this reduction would automatically apply to all GATT signatories. There were leakage clauses allowing countries to negotiate exemptions if their domestic producers were particularly harmed by tariff reductions. In 1947, the United Nations negotiated the general agreement on tariffs and trade.
This contract has created a body to verify and resolve trade disputes between its members. Members continue to update the underlying contract through a series of “rounds” of negotiations. The SPS agreement has changed the way trade decisions are made with respect to agricultural products. Its main intention is to facilitate trade and avoid the use of sanitary and plant health measures as unjustified barriers to trade. The agreement stipulates that all measures must be scientifically sound and should not be unnecessarily restrictive, while recognizing the right of countries to the protection of human, animal or plant life or health. This series of meetings and reduced rates would continue, allowing for new GATT provisions in the process. The average tariff rate rose from about 22% when the GATT was first signed in Geneva in 1947, to about 5% until the end of the 1993 Uruguay Cycle, which also negotiated the creation of the WTO. The General Agreement on Tariffs and Trade (GATT), signed on 30 October 1947 by 23 countries, was a legal agreement aimed at minimizing barriers to international trade by eliminating or reducing quotas. , tariffs and subsidies, while maintaining important rules. The GATT is expected to stimulate economic recovery after the Second World War through the reconstruction and liberalization of world trade.
Although GATT is a legal agreement, it acts as an organization. Eight rounds of negotiations have been completed and the current round, the Doha Development Round, began in 2001 and is still not complete.
