In 2010, the Hillsborough Castle Agreement was waived by the D`Hondt system for the allocation of ministerial posts to allow the inter-communal Alliance Party of Northern Ireland to accept the politically controversial powers of the police and justice system when most of these powers were entrusted to the Assembly. Decentralisation took place on 12 April 2010. The power-sharing government returned to Northern Ireland after extensive discussions and the recent publication of a document from the British and Irish governments. Optimistic new Decade, New Approach, it was the mechanism that was found to bring political parties back together to government three years after the collapse of the Assembly. It is a detailed text containing many proposals, plans and initiatives; relative inconsistency is evidence of conflicting challenges. At the heart of the dilemma is how to encourage representatives of Northern Ireland`s two main (nationalist-unionist) communities to share power again. Prime Minister Boris Johnson welcomed the deal and tweeted it was a “great step forward for the people of Northern Ireland.” In February 2018, an agreement appeared to be reached, but at the last moment it collapsed due to a disagreement between the DUP and Sinn Féin over the proposed text. At the end of the fifth round of negotiations, the parties agreed on an agreement that should serve as the basis for a restored executive. The New Decade, New Approach agreement[1] was jointly published by the Secretary of State for Northern Ireland and the Irish Prime Minister. Disagreements and disputes will continue, particularly with the British government, but also between the parties themselves.
There is still a lot of work to be done, and there is plenty of room for the old oppositions to reappear quickly. It is difficult to predict the evolution of constitutional and political relations. Life after Brexit, for example, will have a fundamental impact on what happens next. The fact that the United Kingdom withdraws without the agreement of two localities (Scotland and Northern Ireland) is not forgotten by those who do not appreciate the specifics of continuing membership in the trade union state (United Kingdom).
