How a Bill Becomes Law in Northern Ireland
Every law the Northern Ireland Assembly makes starts life as a bill — a draft law — and must pass through seven stages before it becomes an Act. This guide walks through each stage, who can introduce a bill, and what can speed a bill up or stop it. You can follow the real progress of every current bill on our bill tracker.
Who can introduce a bill?
There are three routes into the Assembly:
- Executive bills — introduced by a minister on behalf of their department. These make up most of the Assembly’s legislation. For example, the Justice Bill was introduced by the Minister of Justice and is scrutinised by the Committee for Justice.
- Private members’ bills — introduced by an individual MLA who is not a minister. Any MLA can propose one, though drafting support is limited and they compete for Assembly time.
- Committee bills — introduced by an Assembly committee. These are rare.
A bill must be within the Assembly’s legislative competence — it can only deal with transferred (devolved) matters and must comply with human-rights and other legal limits. See our guide to devolved, reserved and excepted powers.
The seven stages
1. First Stage. The bill is formally introduced: its title is read out in the Chamber and the text is published. There is no debate or vote.
2. Second Stage. The Assembly debates the bill’s general principles — should there be a law about this at all? — and votes. If the bill fails here, it falls.
3. Committee Stage. The bill goes to the relevant committee — usually the statutory committee that shadows the sponsoring department — for detailed, clause-by-clause scrutiny. The committee takes written and oral evidence from officials, experts and the public, then publishes a report recommending changes. This is typically the longest stage, and the main opportunity for outside voices to shape the law.
4. Consideration Stage. Back in the Chamber, the whole Assembly examines the bill clause by clause and votes on amendments. This is where the committee’s recommendations — and other MLAs’ proposals — are accepted or rejected.
5. Further Consideration Stage. A second amendment stage. Only the amendments tabled are debated, giving MLAs a final chance to refine the text.
6. Final Stage. The Assembly debates and votes on the bill as a whole. No further amendments are possible — it passes or falls.
7. Royal Assent. After a short period in which the bill’s legal competence can be checked (and, in limited circumstances, challenged in court), the bill is submitted for Royal Assent and becomes an Act of the Northern Ireland Assembly. Some or all of its provisions may still need a commencement order before they take effect.
Accelerated passage: skipping Committee Stage
In urgent cases a bill can go through accelerated passage, which skips Committee Stage entirely. The Assembly must agree to this by a cross-community vote, and the sponsoring minister must explain why it is needed. In practice it is used routinely for Budget Bills — for example the Budget Bill (2026) — because spending authority is time-critical, and occasionally for other urgent legislation. Because it removes the main scrutiny stage, its use for anything other than budget legislation tends to attract criticism from across the Chamber.
What can stop a bill?
A bill can fall at any voting stage if a majority votes against it. In addition:
- A petition of concern — signed by 30 MLAs from at least two parties — can require a vote to pass with cross-community support instead of a simple majority. See how votes work.
- Bills that have not completed all stages when an Assembly mandate ends fall — they must be reintroduced from scratch in the next mandate.
- The courts can, in limited circumstances, be asked to rule on whether a bill is within the Assembly’s powers before Royal Assent.
