What this dot point is asking
You need to explain how the Northern Ireland Assembly is elected and composed, its three main functions of representation, legislation and scrutiny, the cross-community voting rules and the petition of concern, the committee system, and how far the Assembly is independent of the Executive. The CCEA AS 1 paper rewards precise knowledge of how Stormont actually works and a balanced judgement on how effectively it does its job.
Composition and election
The use of STV rather than first-past-the-post is deliberate: in a divided society, a majoritarian system would entrench a permanent unionist majority, whereas STV gives minority parties and communities fair representation. On entering office MLAs designate as unionist, nationalist or other, which matters for the cross-community voting rules below.
The three functions
The Assembly, like Westminster, exists to represent, legislate and scrutinise, but the cross-community safeguards shape how it does each.
- Representation. MLAs raise constituents' concerns, hold surgeries, table questions and reflect the full range of community opinion that STV returns to the chamber.
- Legislation. The Assembly makes primary law for transferred matters (devolved powers such as health, education, agriculture, the economy and, since 2010, justice). A bill passes through stages: first stage (introduction), second stage (general principles), committee stage (detailed scrutiny by the relevant statutory committee), consideration and further consideration stages (amendments), final stage and Royal Assent.
- Scrutiny. The Assembly holds the Executive to account through statutory committees, question time to ministers, plenary debates, motions and the petition of concern.
Cross-community voting and the petition of concern
To stop one community outvoting the other, certain key decisions cannot be carried by a simple majority alone. Cross-community support is tested in one of two ways:
- Parallel consent: a majority of all MLAs voting, including a majority of designated unionists and a majority of designated nationalists.
- Weighted majority: 60 per cent of MLAs voting, including at least 40 per cent of designated unionists and 40 per cent of designated nationalists.
In practice the petition of concern became controversial because it was used not just to protect minorities but as a routine veto on issues such as same-sex marriage and welfare reform. New Decade, New Approach (2020) therefore reformed it, raising the threshold and adding conditions to limit its misuse.
The committee system
Committees are the Assembly's main scrutiny machinery and give MLAs real influence:
- Statutory committees shadow each government department. They scrutinise the department's policy and spending, take evidence, consider bills at committee stage and can even initiate their own legislation, a stronger role than Westminster select committees.
- Standing committees include the Public Accounts Committee (which examines value for money in public spending), the Committee on Procedures, the Business Committee and the Audit Committee.
This committee system is one of the Assembly's strengths: because the Executive is a mandatory coalition rather than a single party with a majority, committees can be genuinely cross-party and can hold ministers from rival parties to account.
Independence from the Executive
In theory the Assembly is independent of and superior to the Executive: ministers are accountable to it, and committees scrutinise them. In practice the relationship is weaker than the theory suggests. Because the Executive parties between them command most of the chamber, government bills usually pass, and the Executive controls much of the legislative timetable. The clearest limit on the Assembly's independence, however, is instability: when the Executive collapses, the Assembly cannot legislate or scrutinise either, as happened during the 2017 to 2020 suspension over the Renewable Heat Incentive scandal and again from 2022 over the Northern Ireland Protocol.
Examples in context
A model AS paragraph on scrutiny might read: "The Assembly's statutory committees give it a stronger scrutiny role than is sometimes assumed. Because the Executive is a mandatory coalition rather than a single governing party, a statutory committee chaired by one party can rigorously examine a minister from a rival party, as the Health Committee did during the Renewable Heat Incentive controversy. Committees can also initiate legislation, a power Westminster select committees lack. Yet this strength is conditional: when the institutions collapse, scrutiny stops entirely, and during the 2017 to 2020 hiatus there was no committee oversight of how Northern Ireland was governed at all. The judgement, therefore, is that the Assembly's scrutiny machinery is well designed but only as effective as the institutions' survival allows." This combines precise detail with a balanced verdict.

Q3. To what extent is the Northern Ireland Assembly independent of the Executive? [24 marks]
- Cue. Weigh ministers' formal accountability and committee scrutiny against the Executive parties' dominance of the chamber and timetable and the collapses that suspend the Assembly entirely. Reach a substantiated judgement.

A 12-mark AS 1 explain question. Identify the three functions and
explain how the Assembly performs each.
Representation. The 90 MLAs, elected by STV in 18 constituencies,
represent constituents, raise local issues and reflect the range of
opinion across both communities.
Legislation. The Assembly makes primary law for the transferred matters
through a multi-stage process of bill stages and committee scrutiny, and
can amend or reject Executive bills.
Scrutiny. Through statutory committees, question time, debates and the
petition of concern, the Assembly holds ministers and the Executive to
account. A strong answer explains all three with examples.
CCEA AS 2022To what extent does the Northern Ireland Assembly carry out its functions effectively? [24 marks]Show worked answer →
A 24-mark AS 1 evaluation question. Weigh effective performance of the
three functions against the constraints on the Assembly.
Effective. STV produces a broadly proportional, representative chamber;
statutory committees shadow departments and can initiate legislation; the
petition of concern was designed to protect minority interests.
Limited. Repeated collapses (2017 to 2020 and from 2022) meant no
legislating or scrutiny at all for years; the petition of concern was
misused as a routine veto; party discipline and the Executive's dominance
of the timetable weaken backbench scrutiny.
A top answer judges that the Assembly can perform its functions well when
sitting, but its effectiveness is undermined by instability and the misuse
of its safeguards, then reaches a clear verdict.
