If passed, the bill would be an «extremely serious violation» of the withdrawal agreement and international law. The United Kingdom (United Kingdom) left the European Union (EU) on 31 January 2020. A transitional period is now in effect until 31 December 2020. During this period, the UK will have to comply with all EU rules and legislation. For businesses and the public, virtually nothing will change. After the transition period, there will be changes, whether or not an agreement is reached on the new relationship between the UK and the EU. After an unprecedented vote on 4 December 2018, MEPs ruled that the UK government was not respecting Parliament because it refused to give Parliament full legal advice on the consequences of its proposed withdrawal terms.  The focus of the consultation was on the legal effect of the «backstop» agreement for Northern Ireland, the Republic of Ireland and the rest of the United Kingdom with regard to the CUSTOMS border between the EU and the United Kingdom and its impact on the Good Friday agreement that led to the end of the unrest in Northern Ireland, including whether , according to the proposals, the UK would be certain that it would be able to leave the EU in a practical sense. On the European Union side, the European Parliament also approved the ratification of the agreement on 29 January 2020 and the Council of the European Union approved the conclusion of the agreement by e-mail on 30 January 2020.  That is why, on 30 January 2020, the European Union also tabled its instrument for ratification of the agreement, concluding the agreement and allowing it to enter into force on the date of the UK`s withdrawal from the EU on 31 January 2020, at 11 .m GMT.
On 6 September 2020, the Financial Times reported that the UK government was considering drafting new laws to circumvent the protocol of the Northern Ireland Withdrawal Agreement.  The new law would give ministers the power to determine which state aid should be notified to the EU and to define which products at risk of being transferred from Northern Ireland to Ireland (the withdrawal agreement stipulates that in the absence of a reciprocal agreement, all products are considered vulnerable).  The government defended this approach and stated that the legislation was in accordance with protocol and that it had only «clarified» the volumity in the protocol.  Ursula von der Leyen warned Johnson not to violate international law and said that the implementation of the withdrawal agreement by Britain was a «precondition for any future partnership».  On 8 September, the Minister of Foreign Affairs for Northern Ireland, Brandon Lewis, told the British Parliament that the government`s internal market bill would «violate international law».»  He called on the government to withdraw the bill «by the end of the month,» adding that the withdrawal agreement contained «a number of mechanisms and remedies to remedy violations of the legal obligations contained in the text – which the European Union will not hesitate to use.»
