It has power to legislate in a wide range of areas that are not explicitly [[reserved and excepted matters|reserved]] to the [[Parliament of the United Kingdom]], and to appoint the [[Northern Ireland Executive]]. It sits at [[Parliament Buildings (Northern Ireland)|Parliament Buildings]] at [[Stormont Estate|Stormont]] in [[Belfast]].

The Assembly is a [[unicameralism|unicameral]], democratically elected body comprising 90 members<ref>After the [[2017 Northern Ireland Assembly election|March 2017 elections]], previously 108.</ref> known as [[Member of the Legislative Assembly (Northern Ireland)|members of the Legislative Assembly]] (MLAs). Members are elected under the [[single transferable vote]] form of [[proportional representation]] (STV-PR).<ref>{{cite web|last1=Whyte|first1=Nicholas|title=The Single Transferable Vote (STV)|url=http://www.ark.ac.uk/elections/gstv.htm|website=Northern Ireland Elections|access-date=28 June 2016|archive-date=7 October 2018|archive-url=https://web.archive.org/web/20181007064514/http://www.ark.ac.uk/elections/gstv.htm|url-status=live}}</ref> In turn, the Assembly selects most of the ministers of the Northern Ireland Executive using the principle of [[Consociationalism|power-sharing]] under the [[D'Hondt method]] to ensure that Northern Ireland's largest voting blocs, [[Unionism in Ireland|British unionists]] and [[Irish nationalism|Irish nationalists]], both participate in governing the region. The Assembly's standing orders allow for certain contentious motions to require a [[cross-community vote]]; in addition to requiring the support of an overall majority of members, such votes must also be supported by a majority within both blocs in order to pass.

The Assembly is one of two "mutually inter-dependent" institutions created under the 1998 [[Belfast Agreement|Good Friday Agreement]], the other being the [[North/South Ministerial Council]] with the [[Republic of Ireland]].<ref>{{citation|title=Peace Agreements and Human Rights|first=Christine|last=Bell|publisher=Oxford University Press|location=Oxford|year=2003|page=141|quote=The agreement makes it clear that the North-South Ministerial Council and the Northern Ireland Assembly are 'mutually inter-dependent, and that one cannot successfully function without the other'. This interdependence is constructed so as to ensure that nationalists and unionists cannot 'cherrypick' the aspects of government that they particularly want to implement. Thus, unionists only get the Assembly and devolved power if they operate the cross-border mechanisms, and for nationalists the situation is reversed.}}</ref> The Agreement aimed to end Northern Ireland's violent 30-year [[The Troubles|Troubles]]. The [[1998 Northern Ireland Assembly election|first Assembly election]] was held in June 1998.

{{Politics of Northern Ireland}}
{{Good Friday Agreement}}

===Previous legislatures===
From June 1921 until March 1972, the devolved legislature for Northern Ireland was the [[Parliament of Northern Ireland]], established by the [[Government of Ireland Act 1920]] and meeting from 1932 at [[Parliament Buildings (Northern Ireland)|Stormont]], outside Belfast. Due to [[gerrymandering]] practices, the Parliament always had an [[Ulster Unionist Party]] (UUP) majority and always elected a UUP [[Government of Northern Ireland|administration]]. For its first two elections it used [[proportional representation]] ([[Single transferable voting]]) but switched to [[First-past-the-post voting]] in 1929.

It was suspended by the UK Government on 30 March 1972 and formally abolished in 1973 under the [[Northern Ireland Constitution Act 1973]].

Northern Ireland was subsequently administered by [[direct rule]] until 1999, with a brief exception in 1974.  Attempts began to restore on a new basis that would see power shared between [[Irish nationalist|nationalists]] and [[Unionism in Ireland|unionists]]. To this end a new legislature, the [[Northern Ireland Assembly, 1973|Northern Ireland Assembly]], was established in 1973 with a power-sharing [[Northern Ireland Executive, 1974|Executive]] taking office in January 1974. However, this body was brought down by the [[Ulster Workers' Council strike]] in May 1974. Political discussions continued against the continued backdrop of [[the Troubles]]. In 1982, another [[Northern Ireland Assembly (1982)|Northern Ireland Assembly]] was established, initially as a body to scrutinise the actions of the [[Northern Ireland Civil Service]] and the [[Secretary of State for Northern Ireland|Secretary of State]], the UK Government minister with responsibility for Northern Ireland. It was not supported by Irish nationalists and was officially dissolved in 1986.

===1998–2002===
The [[Northern Ireland Act 1998|Northern Ireland (Elections) Act 1998]] formally established the Assembly in law under the name '''New Northern Ireland Assembly''', in accordance with the [[Good Friday Agreement|Good Friday (or Belfast) Agreement]]. The first election of members of the New Northern Ireland Assembly was on 25 June 1998 and it first met on 1 July 1998. However, it only existed in "shadow" form until 2 December 1999 when full powers were devolved to the Assembly. Since then the Assembly has operated with several interruptions and has been suspended on six occasions:
* 11 February – 30 May 2000
* 10 August 2001 (24-hour suspension)
* 22 September 2001 (24-hour suspension)
* 14 October 2002 – 7 May 2007
* 9 January 2017 – 11 January 2020
* 3 February 2022 – 3 February 2024

Attempts to secure its operation on a permanent basis were initially frustrated by disagreements between the two main unionist parties (the [[Democratic Unionist Party]] (DUP) and the [[Ulster Unionist Party]]) and [[Sinn Féin]]. Unionist representatives refused to participate in the Good Friday Agreement's institutions alongside Sinn Féin until they were assured that the IRA had discontinued its activities, decommissioned its weapons, and disbanded.

===2002–2007 (suspension)===
The Assembly's suspension from October 2002 to May 2007 occurred when unionist parties withdrew from the [[Northern Ireland Executive]] after Sinn Féin's offices at Stormont were raided by police, who were investigating allegations of intelligence gathering on behalf of the IRA by members of the party's support staff. The Assembly, already suspended, was dissolved on 28 April 2003 as scheduled, but the elections due the following month were postponed by the UK Government and were not held until November that year.

Although the Assembly remained suspended from 2002 until 2007, the members elected at the [[2003 Northern Ireland Assembly election|2003 Assembly election]] were called together on 15 May 2006 under the [[Northern Ireland Act 2006]] to meet in an Assembly to be technically known as  "the Assembly established under the Northern Ireland Act 2006" for the purpose of electing a First Minister and  {{notatypo|deputy}} First Minister<!-- For reasons explained at [[Good Friday Agreement]], this title is always given as "deputy First Minister", never as "Deputy First Minister". (It would have been so much easier had they agreed on "Joint First Minister" but that was too difficult to accept.) -->  and choosing the members of an Executive before 25 November 2006 as a preliminary to the restoration of the Northern Ireland Executive.<ref>{{cite web |url=http://www.opsi.gov.uk/acts/acts2006/20060017.htm |title=Northern Ireland Act 2006 (c. 17) |publisher=Opsi.gov.uk |access-date=28 October 2008 |archive-date=8 September 2008 |archive-url=https://web.archive.org/web/20080908104116/http://www.opsi.gov.uk/acts/acts2006/20060017.htm |url-status=live }}</ref>

Multi-party talks in October 2006 resulted in the [[St Andrews Agreement]], wherein Sinn Féin committed to support the [[Police Service of Northern Ireland]] and the mechanism for nominating First and deputy First Ministers was changed.  In May 2006, [[Ian Paisley]], leader of the DUP, had refused Sinn Féin's nomination to be [[Office of the First Minister and deputy First Minister|First Minister]] alongside Sinn Féin's chief negotiator, [[Martin McGuinness]], as deputy First Minister; after the St Andrews Agreement, these positions were now chosen by larger parties only, while the holders of other positions were elected by sitting MLAs. [[Eileen Bell]] was appointed by the [[Secretary of State for Northern Ireland|Secretary of State]], [[Peter Hain]], to be the interim speaker of the Assembly, with [[Francie Molloy]] and [[Jim Wells (politician)|Jim Wells]] acting as deputy speakers.<ref>{{cite web |url=http://www.niassembly.gov.uk/theassembly/main.htm |title=The Assembly – Main Page |publisher=Niassembly.gov.uk |access-date=28 October 2008 |url-status=dead |archive-url=https://web.archive.org/web/20081229020725/http://www.niassembly.gov.uk/theassembly/main.htm |archive-date=29 December 2008 |df=dmy-all }}</ref> The [[Northern Ireland (St Andrews Agreement) Act 2006]] repealed the Northern Ireland Act 2006 and disbanded "the Assembly".

The St Andrews Agreement Act provided for a "Transitional Assembly established under the Northern Ireland (St Andrews Agreement) Act 2006" – to continue to contribute to preparations for the restoration of devolved government. A person who was a member of the Northern Ireland Assembly was also a member of the Transitional Assembly, with the same speaker and deputy speaker as elected for "the Assembly". The Transitional Assembly first met on 24 November 2006 but proceedings were suspended due to a bomb threat by [[Ulster loyalism|loyalist]] paramilitary [[Michael Stone (loyalist paramilitary)|Michael Stone]].<ref name="stoneattack">{{cite news|title=Stone held over Stormont attack|url=https://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6181994.stm|work=[[BBC News Online]]|publisher=BBC|date=24 November 2006|access-date=8 May 2007|archive-date=28 November 2006|archive-url=https://web.archive.org/web/20061128084309/http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6181994.stm|url-status=live}}</ref> It was dissolved on 30 January 2007 when the election campaign for the next Northern Ireland Assembly started.

Subsequently, a new [[2007 Northern Ireland Assembly election|election]] to the suspended Northern Ireland Assembly was held on 7 March 2007. The DUP and Sinn Féin consolidated their positions as the two largest parties in the election and agreed to enter government together. [[Peter Hain]] signed a restoration order on 25 March 2007 allowing for the restoration of devolution at midnight on the following day.<ref name="deadline">{{cite news|title=Parties face deadline at Stormont|url=https://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6493691.stm|work=[[BBC News Online]]|publisher=BBC|date=26 March 2007|access-date=8 May 2007|archive-date=6 August 2012|archive-url=https://web.archive.org/web/20120806154648/http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6493691.stm|url-status=live}}</ref> An administration was eventually established on 10 May with Ian Paisley as First Minister and Martin McGuinness as deputy First Minister.<ref name="historicreturn">{{cite news|title=Historic return for NI Assembly|url=https://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6634373.stm|work=[[BBC News Online]]|publisher=BBC|date=8 May 2007|access-date=8 May 2007|archive-date=9 April 2020|archive-url=https://web.archive.org/web/20200409111723/http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/6634373.stm|url-status=live}}</ref>

=== 2007–2017 ===
This [[Members of the 3rd Northern Ireland Assembly|third Assembly]] was the first legislature in Northern Ireland to complete a full term since the Northern Ireland Parliament which convened [[1969 Northern Ireland general election|between 1965 and 1969]]<ref>{{cite news|url=https://www.bbc.co.uk/news/av/uk-12865791|title=Ian Paisley retires as NI Assembly completes historical first full term|date=25 March 2011|work=BBC News|access-date=20 June 2018|archive-date=1 February 2016|archive-url=https://web.archive.org/web/20160201215320/http://www.bbc.co.uk/news/uk-12865791|url-status=live}}</ref> and saw powers in relation to [[Department of Justice (Northern Ireland)|policing and justice]] transferred from Westminster on 12 April 2010. [[Peter Robinson (Northern Ireland politician)|Peter Robinson]] succeeded Ian Paisley as First Minister and DUP leader in 2008.

A five-year term came into effect with the [[4th Northern Ireland Assembly|fourth Assembly]] [[2011 Northern Ireland Assembly election|elected in 2011]]. The subsequent period was dominated by issues of culture and dealing with the past which culminated in the [[Stormont House Agreement|Fresh Start Agreement]] in 2014. The first [[Northern Ireland Assembly Opposition|Official Opposition]] in the Assembly was formed by the UUP in the closing months of the fourth term. Following the [[2016 Northern Ireland Assembly election|election]] of the [[5th Northern Ireland Assembly|fifth Assembly]] in 2016, the DUP and Sinn Féin formed the [[Executive of the 5th Northern Ireland Assembly|fourth Executive]],<ref>{{Cite news|url=https://www.irishtimes.com/news/politics/claire-sugden-takes-justice-ministry-in-new-ni-executive-1.2660115|title=Claire Sugden takes justice ministry in new NI executive|newspaper=The Irish Times|language=en|access-date=2020-02-02|archive-date=15 May 2020|archive-url=https://web.archive.org/web/20200515055808/https://www.irishtimes.com/news/politics/claire-sugden-takes-justice-ministry-in-new-ni-executive-1.2660115|url-status=live}}</ref> with [[Arlene Foster]] as First Minister and Martin McGuinness continuing deputy First Minister.

=== 2017–2020 (suspension) ===
In the wake of the [[Renewable Heat Incentive scandal]], McGuinness resigned from his post in January 2017, bringing an end to almost a decade of unbroken devolution. Sinn Féin withdrew from the Assembly, and a [[2017 Northern Ireland Assembly election|fresh election]] was held on 2 March 2017.

==Powers and functions==
The Assembly has both legislative powers and responsibility for electing the Northern Ireland Executive. The First and deputy First Ministers were initially elected on a [[cross-community vote]], although this was changed in 2006 and they are now appointed as leaders of the largest parties of the largest and second largest Assembly 'block' (understood to mean 'Unionist', 'Nationalist' and 'Other').<ref>{{Cite web|url=http://www.legislation.gov.uk/ukpga/1998/47/part/III|title=Part III, Northern Ireland Act 1998|website=www.legislation.gov.uk|language=en|access-date=2 April 2017|archive-date=3 April 2017|archive-url=https://web.archive.org/web/20170403020353/http://www.legislation.gov.uk/ukpga/1998/47/part/III|url-status=live}}</ref>  The [[Department of Justice (Northern Ireland)|Minister of Justice]] is appointed by cross-community agreement.<ref>{{Cite web|url=http://www.legislation.gov.uk/ukpga/1998/47/section/21A#(3A)(b)|title=Section 21A, Northern Ireland Act 1998|website=www.legislation.gov.uk|language=en|access-date=2 April 2017|archive-date=3 August 2012|archive-url=https://archive.today/20120803180536/http://www.legislation.gov.uk/ukpga/1998/47/section/21A#(3A)(b)|url-status=live}}</ref> The seven other ministerial positions are distributed among willing parties roughly proportionate to their share of seats in the Assembly by the [[D'Hondt method]], with ministers chosen by the nominating officers of each party.

The Assembly has authority to legislate in a field of competences known as "transferred matters". These matters are not explicitly given in the Northern Ireland Act 1998. Rather they include any competence not explicitly retained by the Parliament at Westminster. Powers reserved by Westminster are divided into "excepted matters", which it retains indefinitely, and "reserved matters", which may be transferred to the competence of the Northern Ireland Assembly at a future date. A list of transferred, reserved and excepted matters is given below.

While the Assembly was in suspension, its legislative powers were exercised by the UK Government, which governs through procedures at Westminster. Laws that would have normally been within the competence of the Assembly were passed by the UK Parliament in the form of [[Order in Council|Orders-in-Council]] rather than Acts of the Assembly.

Further, when the Assembly is suspended, certain devolved matters revert to the remit of the [[British–Irish Intergovernmental Conference]] (BIIGC). The BIIGC guarantees the [[Government of Ireland]] a say in areas of bilateral co-operation and on those matters not yet devolved to the Assembly or the [[North/South Ministerial Council]].<ref>Forman, F. N. :''Constitutional change in the United Kingdom''. University College, London. Constitution Unit. Routledge, 2002, p. 71. {{ISBN|0-415-23035-7}}</ref>

Acts of the Northern Ireland Assembly as with other subordinate legislatures are subject to judicial review. A law can be struck down if it is found to:
* exceed the competences of the Assembly;
* violate retained [[European Union law]];
* are incompatible with human rights as codified in the [[European Convention on Human Rights]]; or
* discriminate against individuals on the grounds of political opinion or religious belief.

===Transferred matters===
A transferred matter is defined as "any matter which is not an excepted or reserved matter".<ref>{{cite legislation UK|type=act|year=1998|chapter=47|section=4|act=Northern Ireland Act 1998|access-date=9 January 2021}}</ref> There is therefore no full listing of transferred matters but they have been grouped into the responsibilities of the [[Northern Ireland Executive]] ministers:
* [[Department of Agriculture and Rural Development|Agriculture, Environment and Rural Affairs]]
* [[Department for Communities|Communities]]
* [[Department for the Economy|Economy]]
* [[Department of Education (Northern Ireland)|Education]]
* [[Department of Finance (Northern Ireland)|Finance]]
* [[Department of Health (Northern Ireland)|Health]]
* [[Department for Infrastructure (Northern Ireland)|Infrastructure]]
* [[Minister of Justice (Northern Ireland)|Justice]]

==Procedure==
The Assembly has three primary mechanisms to ensure effective power-sharing:
* in appointing ministers to the Executive (except for the Minister of Justice), the [[D'Hondt method]] is followed so that ministerial portfolios are divided among the parties in proportion to their strength in the Assembly.<ref>{{cite journal|title=The institutional design of executive formation in Northern Ireland|first=Joanne|last=McEvoy|journal=Regional & Federal Studies|year=2006|volume=16|issue=4|pages=447–464|doi=10.1080/13597560600989037|s2cid=7618735}}</ref> This means that all parties with a significant number of seats are entitled to at least one minister;
* certain resolutions must receive "[[cross-community vote|cross community support]]", or the support of a minimum number of MLAs from both communities, to be passed by the Assembly. Every MLA is officially designated as either nationalist, unionist or other. The election of the [[Speaker of the Northern Ireland Assembly|speaker]],<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1998/47/section/39 |title=Section 39, Northern Ireland Act 1998 |publisher=Legislation.gov.uk |access-date=26 May 2013 |archive-date=3 August 2012 |archive-url=https://archive.today/20120803193059/http://www.legislation.gov.uk/ukpga/1998/47/section/39 |url-status=live }}</ref> appointment of the Minister of Justice, any changes to the standing orders<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1998/47/section/41 |title=Section 41, Northern Ireland Act 1998 |publisher=Legislation.gov.uk |access-date=26 May 2013 |archive-date=5 August 2012 |archive-url=https://archive.today/20120805083159/http://www.legislation.gov.uk/ukpga/1998/47/section/41 |url-status=live }}</ref> and the adoption of certain money bills must all occur with cross-community support. The election of the First and deputy First Ministers previously occurred by parallel consent but the positions are now filled by appointment; and
* Most votes taken by the Assembly can be made dependent on cross-community support if a [[Cross-community vote|petition of concern]] is presented to the speaker. A petition of concern may be brought by 30 or more MLAs, with at least two parties or independent members who were elected to the Assembly as independents in the most recent election being represented among the petitioners.<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1998/47/section/42 |title=Section 42, Northern Ireland Act 1998 |publisher=Legislation.gov.uk |access-date=26 May 2013 |archive-date=3 August 2012 |archive-url=https://archive.today/20120803205703/http://www.legislation.gov.uk/ukpga/1998/47/section/42 |url-status=live }}</ref> Petitions may not be brought on resolutions relating to sanctions of members, on votes relating to the general principles of a bill rather than specific provisions or passage, and matters relating to the full implementation of paragraph 2.2.4 of Annex B of Part 2 of The New Decade, New Approach Deal as specified in the standing orders of the Assembly. In cases where a petition is properly filed, a vote on proposed legislation will only pass if supported by a weighted majority (60%) of members voting, including at least 40% of each of the nationalist and unionist designations present and voting. Effectively this means that, provided enough MLAs from a given community agree, that community (or a sufficiently large party in that community) can exercise a veto over the Assembly's decisions. The purpose is to protect each community from legislation that would favour the other community.

The Assembly has the power to call for witnesses and documents, if the relevant responsibility has been transferred to its remit.<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1998/47/section/44 |title=Section 44, Northern Ireland Act 1998 |publisher=Legislation.gov.uk |access-date=26 May 2013 |archive-date=4 August 2012 |archive-url=https://archive.today/20120804001556/http://www.legislation.gov.uk/ukpga/1998/47/section/44 |url-status=live }}</ref> Proceedings are covered by privilege in [[defamation]] law.<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1998/47/section/50 |title=Section 50, Northern Ireland Act 1998 |publisher=Legislation.gov.uk |access-date=26 May 2013 |archive-date=4 August 2012 |archive-url=https://archive.today/20120804062102/http://www.legislation.gov.uk/ukpga/1998/47/section/50 |url-status=live }}</ref>

The community designation system has been criticised by the cross-community [[Alliance Party of Northern Ireland|Alliance Party]] as entrenching [[sectarianism|sectarian]] divisions.

==Composition==<!-- This section is linked from [[Belfast Agreement]] -->
The Assembly's composition is laid down in the [[Northern Ireland Act 1998]]. It initially had 108 members (MLAs) elected from 18 six-member constituencies on the basis of [[universal adult suffrage]] and the [[single transferable vote]].

This took effect at the March 2017 election.<ref>{{cite news|url=https://www.bbc.com/news/uk-northern-ireland-politics-35555322|title=Stormont election: How results are calculated and reported|work=BBC News|date=23 February 2017|access-date=20 June 2018|archive-date=4 May 2018|archive-url=https://web.archive.org/web/20180504104306/http://www.bbc.com/news/uk-northern-ireland-politics-35555322|url-status=live}}</ref> The constituencies used are the same as those used for elections to the United Kingdom Parliament at Westminster.<ref>Section 33 of the [[Northern Ireland Act 1998]]</ref><ref>{{Cite web|title=FAQs|publisher=Boundary Commission for Northern Ireland|url=http://www.boundarycommission.org.uk/index/current-review/faqs.htm|access-date=10 April 2014|url-status=dead|archive-url=https://web.archive.org/web/20140401011540/http://www.boundarycommission.org.uk/index/current-review/faqs.htm|archive-date=1 April 2014|df=dmy-all}}</ref>

The [[Northern Ireland Act 1998]] provides that, unless the Assembly is dissolved early, elections should occur once every four years on the first Thursday in May. The [[Northern Ireland (Miscellaneous Provisions) Act 2014]] was passed to bring the Northern Ireland Assembly into line with the other devolved legislatures and to extend each Assembly term to five years instead of four. The second election to the Assembly was delayed by the UK government until 26 November 2003. The Assembly is dissolved shortly before the holding of elections on a day chosen by the [[Secretary of State for Northern Ireland|Secretary of State]]. After each election the Assembly must meet within eight days. The Assembly can vote to dissolve itself early by a two-thirds majority of the total number of its members. It is also automatically dissolved if it is unable to elect a [[First Minister and deputy First Minister]] (effectively joint first ministers, the only distinction being in the titles) within six weeks of its first meeting or of those positions becoming vacant. There have been six [[Elections in Northern Ireland#Elections to the Northern Ireland Assembly|elections to the Assembly]] since 1998.

=== Designations ===
The Assembly uses a [[Consociationalism|consociational]] system. Each MLA is free to designate themselves as "Nationalist", "Unionist", or "other", as they see fit, the only requirement being that no member may change their designation more than once during an Assembly session.

The system has been criticised by some, in particular the cross-community [[Alliance Party of Northern Ireland|Alliance Party]], as entrenching [[sectarianism|sectarian]] divisions.{{cn|date=February 2024}} Alliance supports ending the official designation of identity requirement and the taking of important votes on the basis of an ordinary [[supermajority|super-majority]],{{cn|date=February 2024}} as does the largest unionist party, the [[Democratic Unionist Party|DUP]].{{cn|date=February 2024}}

===Executive and Opposition===
Which parties can appoint ministers to the [[Northern Ireland Executive]] is determined by a combination of mandatory coalition, the D'Hondt method and cross-community support, depending on the role, as explained above. Coalitions of between three and five parties have governed over the Assembly's history. The Executive of the Sixth Assembly was formed on 11 January 2020.

{{NI Executive}}
Unlike the [[United Kingdom Parliament]] and the [[Oireachtas]] (Irish Parliament), the Assembly had no provision for an [[Parliamentary opposition|official opposition]] to hold governing parties to account until legislation was passed in 2016.<ref>{{Cite web|url=http://www.niassembly.gov.uk/globalassets/documents/legislation/bills/non-executive-bills/session-2015-2016/assembly-and-executive-reform-assembly-opposition-bill/assembly-opposition-bill---as-introduced.pdf|title=Assembly and Executive Reform (Assembly Opposition) Bill|access-date=6 March 2017|archive-date=3 April 2016|archive-url=https://web.archive.org/web/20160403205103/http://www.niassembly.gov.uk/globalassets/documents/legislation/bills/non-executive-bills/session-2015-2016/assembly-and-executive-reform-assembly-opposition-bill/assembly-opposition-bill---as-introduced.pdf|url-status=live}}</ref><ref>{{Cite web|url=http://www.legislation.gov.uk/nia/2016/10/contents/data.htm|title=Assembly and Executive Reform (Assembly Opposition) Act (Northern Ireland) 2016|website=www.legislation.gov.uk|access-date=29 August 2019|archive-date=29 August 2019|archive-url=https://web.archive.org/web/20190829001039/http://www.legislation.gov.uk/nia/2016/10/contents/data.htm|url-status=live}}</ref> A party may now form or join an [[Northern Ireland Assembly Opposition|Assembly Opposition]], granting it additional speaking, scrutiny and funding rights, if it was entitled to Ministerial roles under the D'Hondt method and declined them, or if it wins 8% or more of the seats. This opportunity was qualified for and taken by the UUP and SDLP following the 2016 election. Even within the Executive, however, the parties (which have collectively held large majorities in the Assembly) have frequently voted against each other due to political and/or policy differences.

===Historical participation===
Alongside independents, a total of 15 parties have held seats in the Assembly since 1998:

'''Unionist:'''
* [[Ulster Unionist Party]]
* [[Democratic Unionist Party]]
* [[Progressive Unionist Party]]
* [[UK Independence Party]]
* [[Traditional Unionist Voice]]
* [[NI21]]
* [[United Unionist Coalition]]
* [[UK Unionist Party]]
* [[Northern Ireland Unionist Party]]
'''Nationalist:'''
* [[Social Democratic and Labour Party]]
* [[Sinn Féin]]
'''Other:'''
* [[Alliance Party of Northern Ireland]]
* [[Green Party Northern Ireland]]
* [[People Before Profit]]
* [[Northern Ireland Women's Coalition]]

===Election results and changes===

The course of the Assembly saw a marked shift in party allegiance among voters. At the 2003 election, the [[Democratic Unionist Party|DUP]] and [[Sinn Féin]] displaced the more moderate [[Ulster Unionist Party|UUP]] and [[Social Democratic and Labour Party|SDLP]] as the largest parties in the unionist and nationalist blocks. The parties only agreed to share power after four years of negotiations and a new election.

The DUP, Sinn Féin, SDLP and UUP have remained the largest parties in the Assembly and so far the only ones entitled to ministerial roles in the Executive under the D'Hondt method. However, there has been growing support for parties designated "Other". The centrist [[Alliance Party of Northern Ireland|Alliance]] party secured the roles of Speaker from 1998 to 2007 and Minister of Justice from 2010 to 2016 (and again from 11 January 2020) thanks to cross-community support, and has seen an increase in its seat wins from 6 to 8. While the [[Northern Ireland Women's Coalition|NI Women's Coalition]] disbanded in 2003, two leftist parties, the [[Green Party in Northern Ireland]] and [[People Before Profit]], won their first seats, in 2007 and 2016, respectively.

A rapidly shifting landscape of smaller unionist parties has also been a feature of the Assembly. In 1999 the [[UK Unionist Party]] lost four of its five MLAs, disagreeing over a protest against Sinn Féin. The four formed the [[Northern Ireland Unionist Party|NI Unionist Party]], which again suffered a split and won no seats in the 2003 election. That election also saw the electoral demise of a loose trio of independently elected unionists who had united as the [[United Unionist Coalition]]. Minor unionist parties flourished again after the 2011 election, which saw the disappearance of the [[Progressive Unionist Party|PUP]] from the Assembly and the election of the [[Traditional Unionist Voice|TUV]], a splinter group from the DUP opposed to the St Andrews Agreement. In 2012, a suspended UUP member became [[UK Independence Party|UKIP]]'s first MLA, and in 2013, two UUP MLAs resigned to form the progressive [[NI21]],<ref name=":1">{{cite news|url=https://www.bbc.co.uk/news/uk-northern-ireland-22802094|title=NI21 to offer opposition: Basil McCrea and John McCallister|work=BBC News|date=6 June 2013|access-date=20 June 2018|archive-date=16 December 2018|archive-url=https://web.archive.org/web/20181216142639/https://www.bbc.co.uk/news/uk-northern-ireland-22802094|url-status=live}}</ref> which later split.<ref name=":2">{{cite news|url=https://www.bbc.com/news/uk-northern-ireland-28128655|title=John McCallister confirms NI21 exit|work=BBC News|date=3 July 2014|access-date=20 June 2018|archive-date=21 July 2018|archive-url=https://web.archive.org/web/20180721070939/https://www.bbc.com/news/uk-northern-ireland-28128655|url-status=live}}</ref> Of these only the TUV survived the 2016 and 2017 elections.

A 5th Executive was formed on 11 January 2020 following the 2017 election results, which saw the unionist block lose its Assembly majority for the first time.<ref>{{Cite news|url=https://www.bbc.co.uk/news/uk-northern-ireland-39166355|title=Assembly election 'a brutal result for unionism'|last=McClafferty|first=Enda|date=4 March 2017|work=BBC News|access-date=29 April 2017|language=en-GB|archive-date=22 April 2017|archive-url=https://web.archive.org/web/20170422180531/http://www.bbc.co.uk/news/uk-northern-ireland-39166355|url-status=live}}</ref> The usual four largest parties had won enough seats to win ministerial roles under D'Hondt (the DUP three, Sinn Féin two and the SDLP and UUP one each provided neither of them choose to enter opposition<ref>{{Cite web|url=http://archive.niassembly.gov.uk/io/summary/d'hondt.htm |title=D'Hondt, Northern Ireland Assembly |last=Assembly Information Office |date=12 January 1999 |website=archive.niassembly.gov.uk |access-date=2 April 2017 |archive-date=1 April 2017 |archive-url=https://web.archive.org/web/20170401112856/http://archive.niassembly.gov.uk/io/summary/d%27hondt.htm |url-status=live}}</ref>). With the reduction in the number of Assembly seats, the [[Northern Ireland Assembly Opposition|8% threshold]] now amounts to eight rather than nine seats, qualifying Alliance to enter official opposition had they chosen to so, which they did not. The Greens retained their two seats and the TUV and Claire Sugden their single seats, while People Before Profit now held only one seat.

The 6th Executive, formed on 3 February 2024, is notable in several respects: Sinn Féin became the largest party in the 2022 election and took the role of First Minister as well as both economic portfolios, and the SDLP for the first time did not qualify for any seats in the Executive, instead forming the Official Opposition.<ref name=":4" />

<!--In the First Assembly (1998–2003) the four largest parties (the UUP, SDLP, DUP and Sinn Féin) participated in the Executive. Following the suspension of devolution during the Second Assembly (2003–2007), the Third Assembly (2007–2011) saw those four parties resume government, joined in 2010 by Alliance when policing and justice was devolved. This coalition continued in the Fourth Assembly (2011–2016) until 2015 when the UUP withdrew. In the Fifth Assembly (2016–2017) only the DUP, Sinn Féin and independent unionist Claire Sugden held executive posts.

During the First Assembly (1998–2003), the non-Executive parties (thus in opposition) were as follows:
* [[Alliance Party of Northern Ireland]] (6 seats)
* [[UK Unionist Party]] (5 seats reduced to 1 from 1999)
* [[Northern Ireland Unionist Party]] (4 seats from 1999)
* [[Progressive Unionist Party]] (2 seats)
* [[Northern Ireland Women's Coalition]] (2 seats)

The above parties held 15 seats at their full strength. In the Second Assembly (2003–2007), the number of opposition MLAs was reduced to eight, from the following parties:
* [[Alliance Party of Northern Ireland]] (6 seats)
* [[UK Unionist Party]] (1 seat)
* [[Progressive Unionist Party]] (1 seat)

That number increased to nine at the [[2007 Northern Ireland Assembly election|2007 Assembly election]]:
* [[Alliance Party of Northern Ireland]] (7 seats)
* [[Green Party in Northern Ireland]] (1 seat)
* [[Progressive Unionist Party]] (1 seat)

Alliance's accession to the Executive in 2010 left only the [[Green Party in Northern Ireland|Green Party]] and [[Progressive Unionist Party]] as parties outside government.

The Fourth Assembly (2011–2015) saw several shifts of allegiance among members of the smaller parties. At the [[2011 Northern Ireland Assembly election|2011 election]], the PUP lost its single seat while the [[Traditional Unionist Voice]] gained one seat. In 2012 a UUP MLA, [[David McNarry]], was expelled from the party and later joined the [[UK Independence Party]] (UKIP). In 2013, two UUP MLAs [[Basil McCrea]] and [[John McCallister]] left the party, after opposing the decision to have a joint unionist candidate in the [[2013 Mid Ulster by-election|Mid-Ulster by-election]]. They later formed a new party [[NI21]],<ref name=":1">{{cite web|url=https://www.bbc.co.uk/news/uk-northern-ireland-22802094|title=NI21 to offer opposition: Basil McCrea and John McCallister|work=BBC News}}</ref> which McCallister subsequently left.<ref name=":2">{{cite web|url=https://www.bbc.com/news/uk-northern-ireland-28128655|title=John McCallister confirms NI21 exit|work=BBC News}}</ref> The UUP withdrew from the Executive in September 2015,<ref name=":3">{{cite web|url=http://www.belfasttelegraph.co.uk/news/northern-ireland/uup-votes-to-withdraw-from-government-over-provisional-ira-claims-31486828.html|title=UUP votes to withdraw from government over Provisional IRA claims|work=Belfast Telegraph}}</ref> and so the 2011–2016 Assembly closed with an unofficial opposition consisting of the UUP (now with 14 seats), alongside now-independent unionist John McCallister and four minor parties with one seat each: NI21, Green Party, Traditional Unionist Voice and UKIP.
* [[Traditional Unionist Voice]] (1 seat)
* [[Green Party in Northern Ireland]] (1 seat)
* [[UK Independence Party|United Kingdom Independence Party]] (1 seat from 2012)
* [[NI21]] (2 seats from 2013, reduced to 1 from 2014)
* [[Ulster Unionist Party]] (from 2015, 14 seats)

The first official opposition, forming after the [[2016 Northern Ireland Assembly election|2016 election]], comprised:
* [[Ulster Unionist Party]] (16 seats)
* [[Social Democratic and Labour Party]] (12 seats)

Alliance also left government and joined three smaller parties in unofficial opposition:
* [[Alliance Party of Northern Ireland]] (8 seats)
* [[Green Party in Northern Ireland]] (2 seats)
* [[People Before Profit]] (2 seats)
* [[Traditional Unionist Voice]] (1 seat)
With the reduction in the number of Assembly seats at the 2017 election, the 8% threshold now amounts to eight rather than nine seats, qualifying Alliance to enter official opposition if they choose.-->

[[Dáil Éireann]], the lower house of the [[Oireachtas]] (Irish Parliament), uses the same [[single transferable vote]] system for elections as the Assembly but does allow [[List of Dáil by-elections|by-elections]] to fill vacancies. This method is also used for the seats chosen by election in the upper house, [[Seanad Éireann]].

==Organisation==
The Assembly is chaired by the [[Speaker of the Northern Ireland Assembly|speaker]] and three deputy speakers, of whom one is appointed Principal Deputy Speaker. [[John Alderdice|Lord Alderdice]] served as the first speaker of the Assembly from July 1998, but retired in March 2004 to serve as a member of the [[Independent Monitoring Commission]] that supervised paramilitary ceasefires. The position is currently held by the [[Democratic Unionist Party]] MLA [[Edwin Poots]]. In the Assembly, the speaker and ten other members constitute a quorum.

The [[Northern Ireland Assembly Commission|Assembly Commission]] is the body corporate of the Assembly with all that entails. It looks after the pay and pensions of members directly and through tax-payer funded appointees, and the interests of political parties. The very first bill of the Assembly was to do with members' pensions and was taken through with minimum ado by a member of the commission.

The Assembly has <!--chosen to have -->9 statutory committees, each of which is charged with scrutinising the activities of a single ministerial department. It also has 6 permanent standing committees and can establish temporary ad hoc committees. The chairmen and deputy chairmen of the committees are chosen by party nominating officers under the [[d'Hondt system]] procedure, used to appoint most ministers. Ordinary committee members are not appointed under this procedure but the Standing Orders require that the share of members of each party on a committee should be roughly proportionate to its share of seats in the Assembly. Committees of the Assembly take decisions by a simple majority vote. The following are the current statutory and standing committees of the Assembly:

===Statutory (departmental) committees===
* [[Committee for the Executive Office|Executive Office Committee]]
* [[Committee for Agriculture, Environment and Rural Affairs|Agriculture, Environment and Rural Affairs Committee]]
* [[Committee for Communities|Communities Committee]]
* [[Committee for the Economy|Economy Committee]]
* [[Committee for Education|Education Committee]]
* [[Committee for Finance|Finance Committee]]
* [[Committee for Health|Health Committee]]
* [[Committee for Infrastructure|Infrastructure Committee]]
* [[Committee for Justice|Justice Committee]]

===Standing committees===
* [[Northern Ireland Assembly and Executive Review Committee|Assembly and Executive Review Committee]]
* [[Northern Ireland Assembly Audit Committee|Audit Committee]]
* [[Northern Ireland Assembly Business Committee|Business Committee]]
* [[Northern Ireland Assembly Committee on Procedures|Procedures Committee]]
* [[Northern Ireland Assembly Public Accounts Committee|Public Accounts Committee]]
