Direct domination of London ended in Northern Ireland when power was formally transferred to the new Northern Ireland Assembly, the North-South Council and the Anglo-Irish Council when the opening decisions of the Anglo-Irish Agreement came into force on 2 December 1999.    Article 4, paragraph 2 of the Anglo-Irish Agreement (the agreement between the British and Irish governments on the implementation of the Belfast Agreement) required both governments to inquire in writing about compliance with the terms of entry into force of the Anglo-Irish Agreement; The latter is expected to come into effect as soon as both notifications are received.  The British government has agreed to participate in a televised ceremony at Iveagh House in Dublin, the Irish Foreign Office. Peter Mandelson, Minister of Northern Ireland, participated in his participation in early December 2, 1999. He exchanged notifications with David Andrews, the Irish Foreign Secretary. Shortly after the ceremony, at 10:30 a.m., the Taoiseach, Bertie Ahern, signed the declaration of formal amendment of Articles 2 and 3 of the Irish Constitution. He then informed the D`il that the Anglo-Irish agreement had entered into force (including some endorsements to the Belfast Agreement).   After years of deadlock, the British government has committed to implementing the legacy-related institutions outlined in the 2014 agreement as part of the January 2020 Stormont Recovery Agreement. However, uncertainty remains, particularly over how Johnson`s government will handle investigations into former members of the British security services for their actions in the northern Ireland conflict. The agreement reaffirmed its commitment to “mutual respect, civil rights and religious freedoms for all within the Community.” The multi-party agreement recognized “the importance of respect, understanding and tolerance with regard to linguistic diversity,” particularly with regard to the Irish language, Ulster Scots and the languages of other ethnic minorities in Northern Ireland, “all of which are part of the cultural richness of the Island of Ireland.” The Good Friday Agreement provided for the creation of the International Independent Commission for Decommissioning (IICD) to monitor, review and verify the complete disarmament of all paramilitary organizations. The deadline for the end of disarmament was May 2000. The Northern Ireland Arms Decommissioning Act (1997), which received royal approval on 27 February 1997, had a provision in section 7 for the creation of an independent decommissioning commission. The law was passed before the agreement was signed in 1998.
That is why the Independent International Commission for Decommissioning was established as soon as the agreement was signed and was led by Canadian General John de Chastelain (1 Disarmament did not begin in 1998). Unionists and Republicans disagreed on the interpretation of the decommissioning wording, with Republicans saying they had no formal ties to the Irish Republican Army (IRA) and were therefore unable to influence the IRA.
