3. The Assembly shall exercise full legislative and executive authority in respect of matters which currently fall within the competence of the six government departments of Northern Ireland, with the possibility of assuming responsibility for other matters, as described elsewhere in this Agreement. As part of the agreement, it was proposed to rely on the existing Anglo-Irish interparliamentary body. Prior to the agreement, the body was composed only of parliamentarians from the British and Irish parliaments. In 2001, as proposed in the agreement, it was extended to include parliamentarians from all members of the Anglo-Irish Council. 4. In the meantime, aspects of the implementation of the multi-party agreement will be discussed at meetings of the parties concerned on a case-by-case basis (taking into account the results of these elections), under the chairmanship of the UK Government or both governments, once the general elections have taken place; Representatives of both governments and all parties concerned may meet under an independent chairmanship to verify the overall implementation of the Agreement. The agreement was approved by voters across the island of Ireland in two referendums on 22 May 1998. In Northern Ireland, in 1998, during the referendum on the Good Friday Agreement in Northern Ireland, voters were asked whether 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 amendments (Nineteenth Amendment to the Constitution of Ireland) to facilitate it.
The two lawyers had to approve the agreement for it to enter into force. London`s direct rule ended in Northern Ireland when power officially left the new Northern Ireland Assembly, the North-South Council of Ministers and the Anglo-Irish Council, when the first regulations relating to the Anglo-Irish Agreement entered into force on 2 December 1999.    In accordance with Article 4(2) of the Anglo-Irish Agreement (Agreement between the British and Irish Governments for the implementation of the Belfast Agreement), the two governments must inform each other in writing of compliance with the conditions for the entry into force of the Anglo-Irish Agreement. entry into force should take place upon receipt of those two notifications.  The British government agreed to participate in a televised ceremony at Iveagh House in Dublin, the Irish Foreign Office. Peter Mandelson, Secretary of State for Northern Ireland, took part very early on 2 December 1999. He spoke with David Andrews, the Irish Foreign Secretary. Shortly after the ceremony, at 10.30am, the Taoiseach, Bertie Ahern, signed the declaration of formal amendment to Articles 2 and 3 of the Irish Constitution. He then announced to Dáil the entry into force of the Anglo-Irish Agreement (including certain supplementary agreements to the Belfast Agreement).   Paisley stepped down as Premier and DUP leadership on June 5, 2008 and was replaced by Peter Robinson in both positions. In the third Northern Ireland Executive, Robinson and McGuinness had the same political relationship as before between Paisley and McGuinness. After serving as the first minister to resign on January 11, 2016, Robinson was replaced by Arlene Foster.
After McGuinness resigned, on January 9, 2017, Stormont`s decentralized government collapsed, as required by the agreement if no new leader is appointed. . . .
