As part of the agreement, it was proposed to build on the existing Inter-Parliamentary Commission in English-Irish. Prior to the agreement, the body was composed only of parliamentarians from the British and Irish assemblies. In 2001, as proposed by the agreement, it was extended to include parliamentarians of all members of the Anglo-Irish Council. Both views have been recognized as legitimate. For the first time, the Irish government agreed, in a binding international agreement, that Northern Ireland was part of the United Kingdom.  The Irish Constitution has also been amended to implicitly recognize Northern Ireland as part of the sovereign territory of the United Kingdom provided that the majority of the population of the island`s two jurisdictions has agreed to a unified Ireland. On the other hand, the language of the agreement reflects a change in the UK`s emphasis on the one-for-eu law to United Ireland.  The agreement therefore left open the question of future sovereignty over Northern Ireland.  The United Kingdom would only violate this issue if it introduced border controls to the Irish Board of Directors. In the event of a non-agreement, the EU should therefore decide whether to force Ireland to violate the Good Friday agreement.
The agreement was approved by voters across the island of Ireland in two referendums on 22 May 1998. In Northern Ireland, in the 1998 referendum on the Good Friday Agreement in Northern Ireland, voters were asked if they supported the multi-party agreement. In the Republic of Ireland, voters were asked whether they would allow the state to sign the agreement and authorize the necessary constitutional changes (nineteen constitutional amendments from Ireland) to facilitate it. The citizens of both countries had to approve the agreement to implement it. The agreement sets out a framework for the creation and number of institutions in three “parts.” The previous text contains only four articles; It is this short text that is the legal agreement, but it contains the latter agreement in its timetables.  Technically, this proposed agreement can be distinguished as a multi-party agreement, unlike the Belfast Agreement itself.  In order to raise awareness among German policy makers, the ESF invited the spokespersons of Belfast, Dublin and Westminster to discuss the facts and scenarios relating to the future of the common travel area, the free movement of goods on the island and the end of EU financial aid.
