Northern Ireland Constitutional Framework
The Good Friday Agreement, the Northern Ireland Act 1998, and the constitutional position of Northern Ireland within the United Kingdom.
Introducción
Northern Ireland's constitutional position rests on the Belfast / Good Friday Agreement (1998), implemented in domestic law by the Northern Ireland Act 1998. The Agreement created the devolved Northern Ireland Assembly and the power-sharing Northern Ireland Executive, recognised both nationalist and unionist identities (the 'consent principle' — Northern Ireland remains part of the UK unless a majority votes otherwise), and established North-South and East-West institutional arrangements. The Windsor Framework (2023) replaced the Northern Ireland Protocol and adjusted the post-Brexit trading arrangements. Section 75 of the 1998 Act imposes a positive equality duty on public bodies — one of the most far-reaching equality duties in UK law.

Frequently Asked Questions
What is the 'consent principle'?
The principle confirmed by the Belfast Agreement and enshrined in s.1 NIA 1998: Northern Ireland remains part of the UK unless a majority votes otherwise in a poll. If a majority votes for unification with Ireland, the UK and Irish governments are required to give effect to that wish.
How does section 75 differ from the Equality Act 2010?
Section 75 NIA 1998 imposes a positive duty on public authorities to have due regard to the need to promote equality of opportunity across 9 categories (religion, political opinion, age, disability, marital status, sexual orientation, sex, race, persons with dependants). The Equality Act 2010 applies in NI too, but s.75 is a distinctively NI obligation with mandatory equality impact assessments.
What is the role of the Northern Ireland Human Rights Commission?
Established by the Northern Ireland Act 1998 s.68, the NIHRC is an independent statutory body that promotes awareness of human rights, advises government on legislative compatibility with the Human Rights Act 1998, conducts investigations, supports strategic litigation, and may take cases in its own name on important human rights points. The Commission's work on a Northern Ireland Bill of Rights has been the subject of ongoing political negotiation since the Belfast Agreement committed to such a Bill.
