How Assembly Committees Work
Most of the Northern Ireland Assembly’s detailed scrutiny happens not in the Chamber but in its committees — smaller cross-party groups of MLAs that examine bills line by line, question ministers and officials, and investigate how departments spend money and deliver services. This guide explains the three types of committee, how members are chosen, and what committees can actually do.
Statutory committees: shadowing the departments
Each of the nine Executive departments is shadowed by a statutory committee, created under the Northern Ireland Act 1998. The pairing is one-to-one: the Committee for Health scrutinises the Department of Health, the Committee for Education scrutinises the Department of Education, and so on. The Executive Office is scrutinised by the Committee for The Executive Office.
Statutory committees have four core powers: to advise and assist the minister on policy; to take the Committee Stage of bills (see how a bill becomes law); to initiate inquiries and publish reports; and even to propose legislation of their own. They can call for persons and papers — summoning witnesses and requiring documents.
Standing committees: the Assembly's own machinery
Standing committees are permanent committees that deal with the Assembly’s own business rather than a single department:
- The Public Accounts Committee examines whether public money has been spent properly and effectively, working with the NI Audit Office.
- The Committee on Standards and Privileges oversees MLAs’ conduct and the register of interests.
- The Committee on Procedures reviews the Assembly’s Standing Orders.
- The Business Committee, chaired by the Speaker, plans the Assembly’s weekly agenda.
- The Audit Committee and the Assembly and Executive Review Committee handle the Assembly’s own budget and possible reforms to how the institutions work.
- The Windsor Framework Democratic Scrutiny Committee examines new and amended EU laws that apply to Northern Ireland under the Windsor Framework.
Ad hoc committees: one job, then gone
Ad hoc committees are set up for a single, specific task and dissolved when it is done — most often to take the Committee Stage of a bill that does not belong to any one department’s remit. Two current examples: the Ad Hoc Committee on the Assembly Members (Remuneration Board) Bill and the Ad Hoc Committee on the School Uniforms (Trousers) Bill.
Who sits on committees, and how they're chosen
Committees are typically made up of around nine MLAs, with seats shared out roughly in proportion to party strength in the Assembly, so every committee is cross-party by design. Ministers cannot sit on the statutory committee that scrutinises their own department.
Each committee has a Chairperson and Deputy Chairperson. For statutory committees these positions are allocated to parties using the d’Hondt formula — the same proportional method used to appoint ministers — which means committee chairs are spread across parties, including parties in opposition to the relevant minister. Every committee’s current chair, deputy chair and full membership is listed on its page in our committees directory.
What committee work looks like
Committees usually meet weekly while the Assembly is sitting, mostly in public session at Parliament Buildings. A typical meeting might include a briefing from departmental officials, oral evidence from outside organisations, deliberation on a bill’s clauses, or agreeing a report. Meetings are broadcast and minutes, evidence and reports are published on the Assembly’s website.
For the public, committees are the most accessible point of influence in the legislative process: when a committee runs a call for evidence on a bill or inquiry, anyone — individuals, charities, businesses — can make a written submission.
