evidence: Northern Ireland occupies a unique position in the relationship between the United Kingdom (UK) and the European Union (EU). The Protocol on Ireland/Northern Ireland provides that aspects of EU law continue to apply in Northern Ireland despite it having left the EU with the rest of the UK on 31 January 2020. [...] Moreover, the Protocol requires that amendments or replacements to these acts apply in Northern Ireland. Such dynamic regulatory alignment is necessary to maintain the free movement of goods on the island of Ireland. However, this has proved politically controversial, not least because it involves EU acts applying in Northern Ireland in which, after Brexit, neither the UK nor Northern Ireland has had a direct role in adopting. In June 2022, the UK government proposed domestic legislation – the Northern Ireland Protocol Bill (NIPB) – that would, if enacted, disapply those provisions of the Protocol in UK law that currently provide for the continued application of EU law in Northern Ireland. As the NIPB is still going through the parliamentary process the arrangements for Northern Ireland agreed to by the UK and the EU in the text of the Protocol still apply. This would change if the NIPB is adopted.
