Parliaments across the world are increasingly exploring artificial intelligence (AI) to modernise legislative processes, improve research and strengthen oversight of government activities.
The shift comes as lawmakers face growing pressure to examine complex policies, process large volumes of information and respond to rapid technological changes. AI tools could help parliamentary institutions perform these tasks more efficiently, provided they operate under appropriate safeguards.
A report published by the United Nations Development Programme (UNDP) on October 7, 2026, examines how parliaments are engaging with AI and the support they need to govern the technology in the public interest. It highlights the unique responsibility of legislatures to make laws, hold governments accountable and protect citizens’ interests as AI adoption expands.
The Inter-Parliamentary Union (IPU) has also developed practical guidelines and documented examples of AI applications in legislatures. These resources cover legislative research, document summarisation, parliamentary transcription, public engagement and institutional cybersecurity.
AI Offers New Tools for Lawmaking
Artificial intelligence is creating opportunities to improve how parliamentary institutions prepare, examine and communicate legislation.
One potential application is legislative research. Lawmakers often need to review existing laws, policy papers, court decisions, research findings and international agreements before considering a bill. AI-powered search tools can help retrieve relevant information from large document collections.
AI can also produce preliminary summaries of lengthy bills and policy documents. This may help lawmakers identify key provisions, compare proposals and prepare questions for debates or committee hearings.
Another application involves amendments. Parliamentary staff may use AI to group similar amendments, identify overlapping proposals and flag provisions that could conflict with existing legislation.
However, these tools should support rather than replace legal analysis. Human experts must verify the information, interpret the relevant laws and determine whether proposed changes are appropriate.
The IPU has documented applications in legislatures including Brazil’s Senate and Canada’s House of Commons. Examples include AI-assisted legislative research and automated transcription of plenary sessions and committee meetings.
Technology Could Strengthen Government Oversight
Beyond drafting and reviewing legislation, AI could help parliamentary committees examine government performance.
Committees routinely assess budgets, public expenditure, agency reports and the implementation of government programmes. Reviewing these records can require considerable time, especially when information is spread across different documents and databases.
With reliable data, AI systems could help identify unusual spending patterns, compare expenditure against approved budgets and flag inconsistencies for further investigation.
They could also assist committees in tracking government responses to resolutions, recommendations and audit findings. This would give parliamentary researchers additional tools for identifying outstanding issues that require follow-up.
Nevertheless, an AI-generated alert is not proof of wrongdoing. A flagged transaction or unusual pattern must be investigated using reliable evidence and established procedures.
Effective oversight still depends on access to accurate records, independent verification, cooperation from public institutions and the authority of parliamentary committees to demand explanations.
AI can accelerate the examination of information, but lawmakers remain responsible for drawing conclusions and holding public officials accountable.
Global Legislatures Develop Practical AI Applications
The international parliamentary community is already sharing experiences to help institutions adopt AI responsibly.
The IPU’s collection of AI use cases and case studies includes examples involving legislative document retrieval, bill summarisation, transcription, public engagement and parliamentary data services. It also covers systems designed to support cybersecurity and modernise existing digital infrastructure.
For example, AI-assisted transcription can convert parliamentary speeches and committee discussions into searchable text. This could make proceedings easier to archive, retrieve and analyse.
Translation and automated subtitles can also improve access for citizens who face language or hearing barriers. Meanwhile, AI-powered search tools can help journalists, researchers and members of the public find information in parliamentary records.
Some legislatures are also exploring tools that analyse public submissions on proposed laws. These systems may help organise large volumes of responses and identify recurring concerns.
However, automated analysis must not silence minority opinions or misrepresent public sentiment. Institutions need transparent methods for checking whether AI-generated summaries accurately reflect the submissions received.
AI Governance and Human Oversight Remain Essential
Despite its potential benefits, AI introduces risks that parliamentary institutions must manage carefully.
AI systems can generate inaccurate information, misinterpret legal provisions or reproduce bias in their training data. If lawmakers rely on unverified outputs, these weaknesses could affect legislative debates, policy recommendations and public confidence.
There are also concerns about cybersecurity and confidentiality. Parliamentary institutions handle sensitive documents, internal communications and information relating to national security. Uploading such material to inadequately secured systems could expose it to unauthorised access.
The IPU’s guidelines recommend a strategic, risk-based approach to AI adoption. They emphasise strong governance, ethical considerations, staff training and human oversight. The guidance also stresses that AI should enhance human capabilities rather than replace human judgement in democratic deliberation and decision-making.
Consequently, legislatures need clear rules on which AI tools staff may use, what information they may process and who remains responsible for decisions.
They should also verify AI-generated content, protect confidential data and ensure that citizens can understand how automated systems influence public institutions.
Implications for Nigeria’s National Assembly
The global developments offer practical lessons for Nigeria’s National Assembly as it manages legislative research, committee investigations, public engagement and parliamentary records.
AI-assisted transcription could help preserve Senate and House proceedings in searchable formats. Digital archives equipped with intelligent search functions could also make it easier for lawmakers and researchers to retrieve past debates, bills and committee reports.
Furthermore, AI-supported document analysis could help committees review budget proposals, monitor project implementation and compare government spending with approved allocations. These applications could improve the speed of research and help staff identify issues requiring closer scrutiny.
Public engagement is another potential area. AI tools could organise submissions from citizens and civil society groups during public hearings, making recurring concerns easier to identify. However, the original submissions must remain accessible for verification.
Successful adoption would require investment in secure digital infrastructure, reliable parliamentary records and staff training. The National Assembly would also need clear policies on data protection, accuracy, accountability and the use of external AI platforms.
Nigeria could draw on the IPU’s guidance and international case studies when designing pilot projects suited to its legislative needs. Starting with specific, measurable applications would allow the institution to evaluate benefits and risks before expanding deployment.
Ultimately, artificial intelligence is not a substitute for democratic representation, legal expertise or legislative independence. Its value will depend on whether it helps lawmakers make better-informed decisions, scrutinise government more effectively and serve citizens with greater transparency.
As parliaments worldwide explore AI, the central challenge is to combine technological efficiency with human judgement, institutional accountability and public trust.
