The NI protocol, known as „backstop,“ is supposed to be temporary and applies unless it is replaced by a future relationship agreement that the parties will attempt to reach by December 31, 2020. The protocol provides that the common travel area and North-South cooperation will continue to a large extent as they do today, as well as the internal electricity market (so that some EU legislation on wholesale electricity markets will continue to apply). The withdrawal agreement between the European Union and the United Kingdom sets out the conditions for the UK`s orderly exit from the EU, in accordance with Article 50 of the Treaty on european Union. The 2019 revisions also adapted elements of the political declaration and replaced the word „appropriate“ with „appropriate“ with respect to labour standards. According to Sam Lowe, a trade fellow at the Centre for European Reform, the amendment excludes labour standards from dispute resolution mechanisms.  In addition, the Equal Competition Mechanism has been postponed from the legally binding withdrawal agreement to the political declaration, and the line of the political statement that „the United Kingdom will consider taking into account alignment with trade union rules in the relevant areas“ has been removed.  No. 10 stated that ministers were summoned to a special meeting to „review the draft agreement reached by the negotiating teams in Brussels and decide on the next steps“. Part 6 relates to the institutional provisions underlying the agreement and how to resolve VA disputes.
The main changes to Part 6 of the March 2018 draft relate to disputes related to the agreement itself, which the Commission had originally proposed, should be resolved by the ECJ if they could not be resolved in the Joint Committee. Instead, the November draft proposes, in Article 170, that all disputes that are not settled in the Joint Committee be referred to an independent arbitration tribunal which will give a binding decision on the dispute. However, where litigation requires the interpretation of terms or provisions of EU law, Article 174 obliges the Tribunal to refer them to the ECJ in order to interpret in a binding manner those terms or provisions which the Tribunal must then apply.
