Electoral Boundary Review Commission 2026: Delimitation Timelines, Public Participation Guidelines & Article 89 Framework
IEBC Chairman Erastus Edung Ethekon
The long-awaited electoral boundary review has become a significant constitutional and political issue as communities demand fair representation ahead of the 2027 General Election. The Independent Electoral and Boundaries Commission (IEBC), however, faces a difficult balancing act: fulfilling its constitutional responsibility to review electoral units while observing strict timelines, resolving legal questions and preparing for the next national polls.
In 2026, the debate centres on Article 89 of the Constitution, which establishes the legal framework for constituency and ward delimitation. The exercise determines how electoral boundaries are drawn, how population differences are addressed and how communities participate in decisions that affect their representation in the National Assembly and county assemblies.
The IEBC has indicated that substantive constituency and ward boundary changes will not take place before the 2027 General Election. Its phased approach allows preparatory and technical activities to continue while the commission addresses legal and population-data challenges. The decision has significant implications for communities that had hoped to see new electoral units before the next election. (IEBC boundary review statement).

Article 89: The Constitutional Foundation of Boundary Reviews
Article 89 gives the IEBC responsibility for reviewing the names and boundaries of constituencies and periodically reviewing the number, names and boundaries of wards.
Under Article 89(1), Kenya has 290 constituencies for electing members of the National Assembly. This constitutional limit means that demands for additional constituencies cannot, by themselves, result in an increase in their number. Any expansion would require an appropriate constitutional change rather than an ordinary administrative boundary review.
Article 89(2) requires constituency reviews to take place at intervals of not less than eight years and not more than twelve years. The process must also be completed at least twelve months before a general election of members of Parliament.
The first boundary review under the 2010 Constitution was completed in March 2012, meaning the second review was due by March 2024. The delay has complicated efforts to complete the exercise before the 2027 polls.
The full text of Article 89, published by the Kenya Law Reform Commission, sets out the constitutional requirements governing population quotas, public consultation, boundary adjustments and court challenges.
The IEBC’s position in 2026 reflects the difficulty of completing a comprehensive review within the remaining electoral timetable. According to reporting by the Daily Nation, the commission has cited constitutional deadlines and the need to follow a legally defensible, sequential process.
The decision to defer substantive changes means existing constituency and ward boundaries will remain the basis for the 2027 election unless a lawful determination provides otherwise.
Population Quotas and Fair Representation
Population distribution is central to the delimitation process. Article 89(12) defines the population quota as the number obtained by dividing Kenya’s total population by the number of constituencies or wards, as applicable.
The principle seeks to ensure that electoral units have populations that are as nearly equal as possible. Without this safeguard, voters in heavily populated constituencies could find themselves represented by the same number of elected officials as voters in significantly smaller constituencies, potentially creating disparities in representation.
Nevertheless, population figures are not the only consideration.
Article 89(5) recognises that geographical features, urban centres, community interests, historical connections, economic and cultural ties, and means of communication can justify differences between electoral units.
Article 89(6) permits deviations from the population quota of up to 40 per cent for cities and sparsely populated areas and up to 30 per cent for other areas.
These limits recognise the practical realities of representation. A sparsely populated region with difficult terrain may require a different boundary arrangement from a densely settled urban area. Equally, communities with longstanding social and economic connections may have legitimate reasons to oppose a proposed boundary that separates them.
The IEBC’s delimitation methodology explains how population analysis, geographical information and public representations can inform boundary proposals.
Reliable population data is therefore essential. The commission has indicated that some substantive activities depend on the resolution of legal questions surrounding census information. Its phased approach is intended to allow technical preparations to proceed while matters affecting the validity and use of population data are addressed.
Public Participation and County Memorandum Submission
Public participation is a constitutional requirement, not an optional exercise. Article 89(7) directs the IEBC to consult interested parties during constituency and ward boundary reviews and to work progressively towards population equality.
The process gives residents, county governments, community organisations, elected leaders and other interested parties an opportunity to explain how proposed boundaries could affect representation, access to services and community relationships.
County memoranda can provide evidence that may not be immediately apparent from population statistics alone. Residents might raise concerns about long travel distances to administrative centres, geographical barriers, historical ties between neighbouring communities or the practical consequences of moving a settlement into another electoral unit.

The IEBC’s published boundary delimitation public information guide describes participation channels used in the review process. These include submitting memoranda to the commission, making oral presentations at scheduled public hearings and engaging through the commission’s official social media platforms.
Interested parties should check the IEBC’s official website and verified communication channels for any new notice specifying submission deadlines, designated offices, electronic submission arrangements or county hearing dates. The existence of earlier submission channels should not be interpreted as confirmation that a new 2026 memorandum window is open.
A well-prepared memorandum should identify the electoral unit concerned, explain the proposed change or objection and provide supporting evidence. Population information, maps, settlement patterns, transport links and records of community consultation can strengthen the submission.
County governments and community representatives should also distinguish between recommendations on existing boundaries and demands for additional constituencies. The latter face the separate constitutional limit of 290 constituencies.
Transparent public participation can help reduce suspicion that boundary decisions are being shaped by political interests. The IEBC must demonstrate that submissions are considered against consistent legal criteria rather than the influence of particular candidates, parties or communities.
The Twelve-Month Gazettement Requirement
Timing is among the most consequential safeguards in Article 89.
Article 89(2) requires constituency boundary reviews to be completed at least twelve months before a general election of members of Parliament. Article 89(4) separately states that if a general election falls within twelve months after a boundary review is completed, the new boundaries shall not take effect for that election.
These provisions should be read together. The first establishes the deadline for completing a review; the second protects an election from the immediate application of boundaries finalised too close to polling day.
Gazettement is also important. Under Article 89(9), the names and detailed boundaries determined by the commission must be published in the Kenya Gazette, subject to the other constitutional provisions. The boundaries take effect upon the dissolution of Parliament first following publication, in accordance with the Constitution.
Gazettement therefore should not be confused with an announcement of proposed changes, a public hearing or the receipt of county memoranda. Each represents a different stage of the process.
For the 2027 General Election, the IEBC’s stated decision not to undertake substantive boundary changes before the polls means communities should not assume that current petitions will automatically alter their electoral units in time for voting.
Article 89(10) also allows a person to apply to the High Court for review of a commission decision made under the article. Under Article 89(11), such an application must be filed within 30 days of publication of the decision in the Gazette and heard and determined within three months of filing.
Delimitation Components and Administrative Responsibilities
The following table summarises the principal constitutional requirements and the administrative responsibilities associated with them.
| Delimitation Component | Statutory Framework | Administrative Mandate |
|---|---|---|
| Number of constituencies | Article 89(1) | Maintain the constitutional limit of 290 constituencies unless the Constitution is lawfully amended. |
| Review intervals | Article 89(2) | Review constituency names and boundaries at intervals of eight to twelve years. |
| Ward boundaries | Articles 89(3) and 89(8) | Periodically review ward numbers, names and boundaries. |
| Population quota | Articles 89(5) and 89(12) | Use official population figures to work towards equitable representation. |
| Permitted population deviations | Article 89(6) | Apply the prescribed margins while considering geographical and settlement differences. |
| Public participation | Article 89(7) | Consult interested parties and consider relevant representations during the review. |
| County memoranda | Article 89(7) and the IEBC Act’s Fifth Schedule | Receive and assess submissions through formally announced participation channels. |
| Review and gazettement timelines | Articles 89(2), 89(4) and 89(9) | Complete reviews within the constitutional timetable and publish approved boundary details in the Gazette. |
| Judicial review | Articles 89(10) and 89(11) | Facilitate legal scrutiny of decisions within the prescribed filing and determination periods. |
What the 2026 Position Means for Communities
The immediate challenge is managing public expectations. Communities seeking better representation may regard the delay as a lost opportunity, particularly in areas experiencing rapid population growth or persistent complaints about unequal representation.
However, conducting a rushed review could create fresh legal disputes, undermine public confidence and disrupt preparations for the next election. A credible process requires defensible population data, transparent criteria, meaningful consultation and sufficient time to address objections.

The IEBC’s preparatory work can help lay the foundation for a more comprehensive exercise after the 2027 General Election. Technical mapping, geographical data validation, staff capacity-building and public education can improve the quality of future decisions, provided the commission communicates clearly about what is being undertaken and what remains pending.
County governments, civil society organisations and residents also have a role in ensuring that future proposals are supported by evidence. Political pressure alone cannot replace the constitutional tests governing delimitation.
