The multi-party agreement required the parties to “use all the influences they might have” to obtain the dismantling of all paramilitary weapons within two years of the adoption of the agreement by referendums. The standardization process has forced the British government to reduce the number and role of its armed forces in Northern Ireland “to a level compatible with a normal peaceful society.” These include the elimination of security measures and the abolition of special emergency powers in Northern Ireland. The Irish government has pledged to conduct a “thorough review” of its violations of national law. But if they do not reach an agreement before the end of the transition period, on December 31, 2020, and if there is no free trade agreement, some of this new bill could come into play. But not on those three points of friction that we have heard so much about in recent days: fishing rights, competition rules and the application of any agreement. The main themes addressed by Sunningdale and dealt with in the Belfast Agreement are the principle of self-determination, the recognition of the two national identities, intergovernmental cooperation between the British and Ireland and legal procedures for compulsory power-sharing, such as inter-community voting and the D`Hondt system for appointing ministers to the executive.   Former IRA member and journalist Tommy McKearney says the main difference is the British government`s intention to negotiate a comprehensive agreement including the IRA and the most intransigent unionists.  With regard to the right to self-determination, two qualifications are recorded by the writer Austen Morgan. First, the transfer of territory from one state to another must be done through an international agreement between the British and Irish governments. Second, the population of Northern Ireland can no longer be alone in united Ireland; They need not only the Irish government, but also the people of their neighbouring country, Ireland, to support unity. Mr Morgan also pointed out that, unlike the Irish Act 1949 and the Northern Ireland Constitution Act 1973, drawn up under Sunningdale, the 1998 agreement and the resulting British legislation explicitly provide for the possibility of a unified Ireland.
 Article 4 of the agreement stipulates that the provisions of the treaty prevail in law, particularly in UK domestic law.
