In addition to facilitating applied tariff reductions, the contribution of the FIRST GATT to trade liberalization includes “the commitment of negotiated tariff reductions for an extended period (more durable in 1955), the determination of the generalized nature of non-discrimination by most-favoured treatment (MFN) and the status of domestic treatment, the guarantee of greater transparency of trade policies and the establishment of a negotiating forum with a view to the peaceful settlement of bilateral disputes. All of these have contributed to streamlining trade policy and reducing trade barriers and political uncertainty.  A general agreement is one of the most important business documents you can have, and here`s the reason. Following the UK`s vote to leave the EU, supporters of leaving the EU have proposed that Article 24(5B) of the treaty could be used to maintain a “halt” in trade conditions between the UK and the EU if the UK leaves the EU without a trade deal, thus preventing the introduction of tariffs. According to proponents of this approach, it could be used to implement an interim agreement until a final agreement of up to ten years is negotiated.  The claim that Article 24 could be used in this way has been criticized as unrealistic by Mark Carney, Liam Fox and others, given that there must be agreement between the parties to paragraph 5c of the Treaty for paragraph 5b to be useful, given that there would be no agreement in the event of a no-deal scenario.
